Does It Affect Your Insurance if Your House Is Underpinned?

If you’re thinking of buying a house that’s been underpinned due to subsidence, people may suggest you’ll find insuring it difficult and expensive. You may even be advised by well-meaning friends not to have your existing house subsidised, for much the same reasons.

The second case flies in the face of reason since even if the warnings were true, the property will still be far safer after underpinning. But is it really true that an underpinned home is harder to insure?

What Is Underpinning?

Underpinning can describe various techniques of strengthening a building’s foundations. This could be done for a number of reasons — subsidence (where the structure is slipping into the weak ground) is the most common, but a building might also be underpinned to provide extra support for a substantial extension.

The two most common methods are mass concrete underpinning and piling. The mass concrete method, also known as traditional underpinning, involves trenches being dug out under the building and filled with concrete.

While this is still the best solution in some cases, it’s being largely replaced by mini-piling, where piles are drilled or driven down to a level where the ground is stronger. The piles then transfer the building’s weight down to the strong soil or bedrock.

Will Underpinning Affect My Insurance?

Insurers tend to be wary of any structure that has ever suffered from subsidence. While underpinning should be seen as a problem solved, they can still be nervous that the subsidence could return.

In the past, that has tended to mean insurance for an underpinned home has been hard to get and more expensive. However, the situation has improved in recent years.

While many mainstream insurance companies are still reluctant to touch an underpinned property, an increasing number recognise that it’s not always bad. Some companies have dedicated underpinning teams, while there are also specialist brokers.

You may need to get specified work done, such as having your drains tested to ensure they’re watertight. However, if you can demonstrate that the underpinning has done its job, you can often find insurance at a reasonable price.

A Good Job Is Essential

This depends, of course, on the insurer being satisfied that the underpinning is secure, making the further risk to the building acceptably low. Consequently, it’s essential that you’ve had an expert job done, not a fix-up by a general builder.

If you want to know more about how specialist underpinning can make your home secure and keep your insurance costs down, feel free to get in touch with us.

Top 10 Construction Trends in 2019

The world is changing faster each year, and the construction industry is no exception. 2019’s top trends may not affect you directly this year, but it’s almost certain that they’ll all soon be commonplace. So what do we all need to prepare for?

1. Designing in the Cloud

Cloud computing is transforming many industries. In the case of construction, it cuts out the need for multiple copies of the building data, eliminating the risk of slight variations creeping in. Everyone involved can use a single version, held in the cloud.

2. Modular Construction

This isn’t a new idea. Since the days of prefabs, modules have been manufactured elsewhere and then assembled on site, but applications for this approach have exploded. Perhaps all buildings will be constructed this way in the future.

3. Robots and Drones

Automating heavy, repetitious and dangerous work is just common sense, and we have the technology now for this. Whether robotic heavy lifting or using drones for hard-to-reach inspections, this is set to grow in the industry.

4. Wearable Technology

From health monitors to smartwatches, wearable technology is growing. Its applications to construction are wide-ranging, from improving health and safety on site to more efficient monitoring of the project.

5. Augmented Reality

A long step beyond virtual reality augmented reality uses an actual view of reality with extra information overlaid. This will allow detailed planning of construction projects using fully augmented simulations.

6. Smart Buildings

Like phones, buildings are starting to become smart, with inbuilt technology that can be upgraded. This means that we’re going to start seeing digital user manuals for buildings, to allow owners to make the best use of the technology.

7. Onsite Construction Labs

For custom-made components of a building, construction labs can use LiDAR data from drones to produce precise designs, which can then be produced using 3D printing technology.

8. Less Use of Cranes

Cranes aren’t always the most efficient technology for constructing or refurbishing buildings, and sometimes they aren’t practical at all. Instead, robotic machinery can be used to deliver components to the relevant place.

9. Waste Management

We’re all conscious these days of how our actions impact the environment, and the construction industry is no exception. The sector has improved on its record of waste production, and this will grow through 2019 and beyond.

10. Quality and Experience

Not all trends are new. The need for experience and high quality in construction projects will never go out of date. If you want to take advantage of U&M’s long experience, why not get in touch to see how we can help you?

Masonry Repair — Everything You Need to Know

The walls of your home do two vital jobs — they support the structure, and they keep out the weather. If they become worn or cracked, their ability to do both jobs is compromised and they need to be repaired. But there are a number of things that can happen to your walls, and it’s important to recognise them.

Repairing Cracked Walls

Walls often develop small cracks as a result of ageing, and the damage can be easily repaired. Sometimes, however, and especially if the cracks are more substantial, they may be symptoms of subsidence. In this case, it’s essential to repair the foundations with underpinning or piling before patching up the walls.

Hairline cracks can be repaired simply with caulk, but more substantial cracks need to be stitched, once underpinning or other structural work is complete. This is normally done from the exterior, using helical wires.

Repairing Worn Masonry

Worn brick or stone can give an old building period charm, but if the wearing becomes too bad the walls are no longer protecting you. In any case, once the external face is gone, deterioration is likely to carry on more quickly.

Various methods of repair are available, depending on the type and severity of the damage. These range from applying clear sealant or lime mortar over the damaged surfaces to partially rebuilding the wall.

Repairing Render

Whether the rendering on your walls is stucco, pebbledash or roughcast, it performs the crucial job of protecting you against the elements. When it starts cracking or bulging, or when patches start falling off, it’s no longer doing the job as effectively.

Except in the most serious cases of render damage, only localised patches need to be replaced. The damaged render should be hacked off, and the exposed wall allowed to dry out, before applying the new render.

Repairing Damp Walls

Damp can get into the walls due to damage to masonry, render or windows, or else because of leaking gutters or internal condensation. Signs to look out for include smells, blistering paint or peeling wallpaper inside, or either white salt or black mould on the walls.

Repair methods will vary depending on the cause of the damp. This may involve repointing the walls, with softer lime-based mortars better for this purpose than modern cement mortar. The damp will also need to be expelled with extractor fans.

A Professional Job

While a few of these jobs (repairing hairline cracks with caulk, for instance) could be done by an expert DIYer, it’s generally best to get professionals in. In any case, you’ll need a professional analysis of the problems, otherwise, you risk missing a serious problem, such as subsidence.

You’re very welcome to get in touch with us for more advice on masonry repair.

Guidelines for Underpinning Your Basement

There are many excellent reasons for adding a basement to your home, from creating an independent flat to having an indoor swimming pool. It’s a major job, though, and one of the most important aspects is ensuring the foundations of your house remain strong. This means underpinning to form the basement.

Why Have a Basement?

Growing families eventually outgrow their homes, and one option is to move to a bigger place. That’s not only a huge upheaval, though — it’s also prohibitively expensive for many people at current house prices.

An increasingly popular alternative is to add a basement to the existing house. This could be used as an extra bedroom or living room, or else as a playroom for the kids or a games room for the whole family. It could even be converted into a flat, perhaps for an older teenager.

Why Would Your Basement Need Underpinning?

If you’re having space under your home excavated for a basement, this means digging under its existing foundations, leaving the whole structure at risk. Underpinning will replace the lost foundations and restore the building to full strength.

There are various approaches to underpinning, but the most likely methods to be used when constructing your basement are either mass concrete underpinning and/or mini piles. The method adopted is chosen for a variety of factors: ground conditions, groundwater, access and proximity to other structures to name a few. The ultimate aim is to transfer the load from the existing structure to the proposed basement level while providing a retaining structure for the ground surrounding the basement.

What Needs to Be Done?

The process of underpinning is an integral part of creating a new basement. It’s therefore preferable to employ a contractor that specialises in both underpinning and constructing basements. The things you’ll need to do include:

  • A professional survey of the site, especially the state of the soil, which will help to determine which kind of underpinning should be used.
  • Check the contractor’s record and specialisation before hiring — it’s important not to hire a general builder with no record of underpinning.
  • Check with your local authority whether you need planning permission.
  • Find out if the work will affect any party wall agreement.
  • Plan ahead for how you’ll deal with the disruption while the work is being carried out.
  • Make sure the contractor you hire will fully clear up and restore the site when the job is over.

Feel free to get in touch with us if you want to know more about underpinning your basement.

Ten Advantages of Driven Piling

Of the two main methods of inserting piles to support foundations, driving is the preferred method across most of Europe. In the UK, though, there’s a stubborn loyalty to the more traditional technique of boring, also known as drilling.

While bored piles certainly have their place, the advantages of driven piles are clear for the majority of situations. Instead of creating a hole and then filling it with grout or cement, driving involves pushing a metal tube into the soil. This is then filled while in situ and can be withdrawn when the filling has solidified.

Here are ten advantages of driven piling.

1. Precasting Piles

Piles can be precast in a variety of sizes and shapes and brought to the site, helping work to proceed faster.

2. Extra Strength

Because driving compacts the adjacent soil, the pile will be more securely fixed into the ground. Its load-bearing capacity will, therefore, be significantly increased, whereas boring techniques can occasionally lead to subsidence.

3. No Spoil

Unlike boring, driving piles doesn’t involve excavating any soil. This means that no spoil will accrue on the site, making it far easier to keep the site neat and tidy.

4. Suitable for Sites with Groundwater

On some sites, it isn’t advisable to bore holes in case of groundwater. Because driving doesn’t create an empty hole at any point, this isn’t a problem.

5. Maintaining Shape

Unlike bored piles, driven piles don’t bulge in soft ground. It’s also rare that they’ll be damaged when subsequent piles are installed.

6. No Curing Time

Because driven piles don’t need time to be cured, they can be installed on the site in their natural sequence. This makes the process more efficient, saving time and cost.

7. Superior Structural Strength

Driven piles will tend to have greater structural strength than bored piles, with high levels of lateral and bending resistance. This makes them suitable for challenging conditions, as well as for more normal use.

8. Shorter Piles

Because driven piles tend to adhere better to the sides, it’s often possible to use shorter piles to achieve the same results.

9. More Eco-Friendly

The combination of more efficient deliveries to the site with no need to dispose of spoil reduces the CO2 footprint of driven piles.

10. Cost Effective

All of this combines to make driving piles a more cost-effective technique than the alternatives. That’s better piles for less money — a win-win situation.

You’re very welcome to get in touch with us if you want to know more about the advantages of driven piling.

Structural Repair — Bring Your Property Back to Health and Safety Standards

If your property is showing signs of structural damage, the worst thing you can do is leave it alone. Furthermore, hope everything will be all right. If you’re a landlord renting out a property, you have a legal obligation to ensure that it’s structurally safe and meets all Health & Safety requirements. In any case, any property owner would be liable if a collapsing building were to cause any injury or any damage to other properties.

What Are the Signs that You May Need Structural Repairs?

The most common causes of structural damage are subsidence, failure or damage to building materials, and poorly restrained walls, although it can also be caused by a traumatic impact. Crucial signs to look out for include:

  • substantial cracks in the walls, either internally or externally
  • door or window frames pulling away from the walls
  • bulging brickwork on the walls
  • sloping floors
  • leaning chimney stacks

If you notice any of these, it’s vital to call in a structural engineer or a company specialising in structural repairs to find out what needs to be done.


If the problem is subsidence caused by poor soil quality or excavations beneath the building, the usual remedy is to have the foundations underpinned. This can be done by adding an extra layer of concrete beneath the existing foundations, but the more popular method today is piling. Here, piles are driven or bored down to a more secure level, allowing them to support the foundations.

In most cases, underpinning the foundations will prevent any further deterioration. However, it may also be necessary to repair damage already done, and this may need various methods.

Repairing the Structure

If the problem hasn’t been caused by subsidence, or if the subsidence has caused structural damage that won’t right itself naturally, a number of techniques are available. These include:

  • crack stitching to repair failed building materials, using stainless steel or resin grout
  • replacement of cavity wall ties, sometimes without having to replace the old ones
  • resin repair and replacement to strengthen structural timbers
  • replacement of lintels without any demolition needed

Structural repairs may seem expensive. However, in many cases (especially in the case of damage through impact) the costs may be covered by your building insurance. In any case, it’s cheaper than writing off the building — or risking legal action.

If you have any suspicions that your property may need structural repair, feel free to get in touch with us, and we’ll be happy to have a look at it.

Piling — The Way It Works

In recent decades, piling has become the method of choice for the majority of underpinning needs. Compared with other methods, it’s quicker, less disruptive, requires less concrete and spoil disposal and is therefore much friendlier on the environment. It can also provide ‘stronger’ underpinning in more poor-quality soils.

What Is Piling?

Piles are either metal or concrete shafts which are inserted into the ground to distribute the load of a structure down to a secure sub-surface layer. They’ve been traditionally used for building large structures, but piling is now widely used in underpinning solutions, although more traditional methods still have their place.

Piles can be either driven straight into the ground or concrete poured into drilled holes. Both systems have their advantages and disadvantages, and one is usually recommended for a given project and ground condition.

Why Use Piling?

If your home is at risk of subsidence, it may need to be underpinned. This could be because the soil quality is weak, there’s a high water table or there are old excavations beneath it.

Piling has the big advantage over other methods of underpinning that the piles reach down much further into the ground. This means they can be anchored in a stronger layer, redistributing the weight of the building down to a level that can hold it.

At one time, the disadvantage of piling was that it required large, disruptive machinery, which wasn’t practical in a domestic building. Modern mini-piles, however, use far more manageable machinery that causes relatively little disruption.

What Are the Types of Piling?

Broadly, piling can be divided into two types. Driving piles, which can focus the power either at the top or toe of the pile, is best suited to soft, squeezing soil. Among the options for driven piles are:

  • Steel Cased Bottom Driven Piles, where the energy is delivered directly to the toe, are an extremely efficient system. This means the machines can be relatively small, so this approach suits confined spaces.
  • Steel Cased Grundomat Driven Piles are powered by compressed air. Sections of casing are inserted and welded together, causing less vibration than other forms of driving.

With augered piles, a hole is bored first and then filled with (reinforced) concrete or grout to make the pile. This tends to have the advantage of causing less vibration than driving. Options include:

  • Sectional Auger Mini Piles are very versatile, especially in restricted spaces. Here, multiple flight sections are inserted.
  • A Grout Injected Continuous Flight Auger is drilled in a single flight or hollow stem. This supports the sides of the hole throughout the process.
  • Helifix Dixie Pile which is a helix ‘screwed’ into the ground providing end bearing capabilities under each helix

Don’t Make These Mistakes When Underpinning Existing Foundations

Underpinning the foundations on a building is a major operation, and the way it’s carried out can have a crucial effect on the building’s future. There are many pitfalls to the process — though fortunately most can be avoided by using expert professionals. Here are the main things to remember.

Get Your Building Professionally Surveyed

The worst thing you can do is dive straight into underpinning. If you see signs that may suggest subsidence, the first step should be to hire a Chartered Surveyor or Structural Engineer to look at the property.

Not all subsidence requires underpinning. Sometimes, it’s as simple as removing a tree whose roots are interfering with the foundations, or getting the drains fixed. The survey will tell you exactly what’s required.

Select the Appropriate Type of Underpinning

Each underpinning technique is the right one in specific circumstances. If you don’t need to excavate far down, traditional mass concrete underpinning may be fine. However, if the survey reveals that the sub-soil is poor to a depth of two metres or more, or that there’s a high water table, you’ll almost certainly need piling.

There are many kinds of piles and piling machines, and the best choice will reflect not only the condition of the ground but also issues such as access and the amount of headroom available. Both the Structural Engineer and the contractor you employ will be able to advise you on this.

Check Out the Legal Aspects

You shouldn’t start any building work without checking whether you need permission. The work may be notifiable under the Building Regulations, and you should also investigate if another building is close enough for the Party Wall Act 1996 to be relevant.

Again, any competent professional can advise you on these points, but it’s your responsibility to make sure you ask the right questions.

Choose the Right Contractor

Underpinning is a job for specialist professionals, not DIYers or a general builder, and your choice of contractor can make the difference between success and a botched job. With a major project, it’s natural to look for ways to keep down the cost, but that can mean going for the cheapest quote, instead of the one offering the best job.

It’s crucial to ensure the firm you choose has substantial specialist experience of underpinning. This will not only mean they have the necessary expertise, but also that they have the equipment required.

Feel free to get in touch with us for any advice or information you might need about your underpinning requirements.

Three Superior Basement Extension Ideas for Summer 2018

In recent years, property prices have gone through the roof, putting the option of moving home beyond the reach of many families, even if they desperately need the space. A far cheaper solution is to extend your existing home, and basement extension has really started catching on recently. Here are three great ideas for a basement extension to think about in 2018.

1. Games Room

Whether it’s the children wanting space to play or the adults wanting their pool or table tennis, fitting it all into a typical family home can be a problem. Equipment needs to be laboriously brought out and set up each time and put away in storage afterwards.

Putting in a basement extension for your games room gives you all the space you need. Your favourite games can be set up permanently for use whenever you want. Or, if it’s primarily for the children, they can have everything from a basketball hoop to climbing ropes installed — though you might want to think about soft flooring.

A games room doesn’t require natural light, though the artificial lighting would have to be efficient. You would need to incorporate good ventilation into the basement extension, though.

2. Self-Contained Flat

Sometimes, their own bedroom isn’t quite enough. Whether you want somewhere for an older teen to feel independent, a granny flat or a guest suite, a basement conversion can be just the answer.

Depending on the amount of space available for your basement, this could be a complete flat or a bedsit. Even in a bedsit, though, careful planning can leave enough room for a small kitchen space, a walk-in shower, a bed and an area to sit and chill.

Unlike a games room, this will require natural light and ventilation to be attractive. That can be achieved by incorporating a light well, also doubling as a means of outside access.

3. Kitchen

A kitchen may not seem the most obvious use for a basement conversion, but it can offer space for the kitchen you’ve always wanted. At the same time, the cramped room you’ve been coping with can be converted into valuable living space.

Like the self-contained flat, a kitchen would need a light well and, even more importantly, excellent ventilation. Outside access to the garden would also be ideal, especially if you grow your own vegetables or herbs.

These are just three of many options for a superior basement conversion to think about for summer 2018. Feel free to get in touch with us to find out more about these or other opportunities.

Why You Should Consider a Basement Construction for Your Home

Very few 20th-century houses have basements, but there are signs that this is being rethought. UK homes are smaller than in most countries, and many of us need more space. There seems a choice between moving to a larger property or sacrificing part of the garden for an extension.

There’s an alternative, though. You could add a basement to your home.

Creating Space with a Basement

A basement, whether included in a new build or retrofitted in an existing house, provides an entire extra floor with no extra footprint or height. It can provide extra living space for a growing family, or else you could have your utility room or garage down there, freeing up space on the main floors.

On the other hand, a basement has many possible uses. You could have a games room, a gym, a home cinema or even a swimming pool. Alternatively, you could convert your basement into a self-contained flat, either for a family member to live independently or to rent out.

And, if you think a basement would be too gloomy for some of those uses, it needn’t be. It’s easy enough to include light wells, which can also be used for access, either as an independent entrance or a fire escape.

Saving Money with a Basement

Moving is an expensive business. It’s been estimated that, with fees and expenses, selling a property worth around £300,000 could cost you up to £28,000 — and that’s before factoring in the higher cost for a larger property.

Excavating and fitting out a basement isn’t cheap, but it’s unlikely to come to that much, unless there are major issues. You’ll have the additional advantage that basements are very energy efficient, since there are few exposed surfaces.

Adding Value with a Basement

A basement can be invaluable just for improving your quality of life by providing extra living space without the costs of moving, but it can also give you a financial boost. The simplest way of achieving this would be to rent it out as a flat, but it can also add real value to your home when you finally sell it.

It makes sense that a house with three storeys and 50% more floor space will sell for significantly more than one with two storeys, and the advantage will far outweigh what you’ve paid out. Property guru Phil Spencer’s estimate on his own basement conversion was that “for every £1 invested into the house, potentially £3 was added to its value.”

How much difference would a basement make to your quality of life? Get in touch to discuss your home’s potential with us.

What Is Progressive Scaffolding?

For most people, scaffolding is just scaffolding. It surrounds buildings of all types and sizes that are being built, repaired and demolished and, at a distance, it all looks much the same.

That’s far from the truth. There are many kinds of scaffolding, each type used in certain circumstances and not others — including progressive scaffolding.

What Is Progressive Scaffolding?

If an average semi or detached house needs structural repairs, it’s likely that the scaffolding will be put up at the start of the job and left till it can be removed. For some jobs, though, it’s not so simple, and progressive scaffolding is needed.

Scaffolding is progressive if it needs to be added to during the course of the work. This may involve the same scaffolding being extended around the building to work on different sections. Most often, though, progressive scaffolding is built up one level at a time, as it’s needed.

This creates challenges of its own. It’s the nature of most scaffolding that the lowest level provides the foundation that supports all higher levels. This means that the initial construction needs to be capable of supporting everything that will be added to it — though this still needs to be checked each time a new level is built.

When Is Progressive Scaffolding Used?

The most common use for progressive scaffolding is for constructing multi-storey buildings. It wouldn’t be practical, for example, to build ten levels of scaffolding straight away, before the building has got beyond the ground floor. Each level is normally added when it’s required, until the scaffolding stretches up to the full height of the finished building.

A different type of progressive scaffolding may be required when one part of a building needs to be worked on at first, but the scaffolding has to be extended in later stages. Extending it around the building has challenges similar to building it up

Can It Be Used for Commercial and Domestic Properties?

Multi-level buildings are put to a wide range of uses — blocks of flats, hotels, office-blocks, shopping complexes and many others. The purpose might be different, but the challenges of construction are similar.

Whether the building is to be put to domestic, commercial or public use, it will need progressive scaffolding to be constructed safely. And that’s also true whether it’s three or four storeys or the latest rival to the Shard.

If you think your project may require progressive scaffolding (or any other kind), you’re welcome to get in touch with us to find out what we can offer.

How Are Construction Piles Injected?

Whether you’re constructing a new building or strengthening an existing one, strong foundations are essential. However, especially if you’re underpinning in a built-up area, you’ll also want to achieve this with a minimum of disruption and nuisance.

In both respects, the ideal solution is often to use construction piles.

What Are Construction Piles?

Piling was originally used for large-scale construction projects, with steel piles. They can also be concrete now and are increasingly being used for domestic properties. It’s quicker and less labour intensive than traditional methods of excavating foundations. It also creates far less displaced soil and debris to be removed.

This is the ideal approach when the soil immediately below the surface is of poor quality or the water table’s high. The piles can be drilled or driven deep into the ground, allowing the building’s weight to be evenly distributed and transferred down to a more stable level.

Drilling Construction Piles

Of the two methods of injecting construction piles, drilling (also known as boring) creates a hole into which the pile is inserted, usually by pouring in concrete or grout. This is particularly useful for going very deep into the ground, though the piles can’t be extended above ground. Drilled piles don’t cause ground heave and involve relatively little noise and vibration.

Among several types of drilled piles, perhaps the most efficient are:

  • Sectional Auger Mini Piles — This is a versatile system, particularly useful for restricted spaces, in which the piles are inserted in multiple flight sections.
  • Grout Injected Continuous Flight Auger — A continuous flight auger is drilled into the ground, providing support for the sides of the hole at all times and causing little vibration.

Driving Construction Piles

Piles can also be driven into the ground, either from the top or the toe. Although driving doesn’t take the piles as deep as drilling, it’s unaffected by ground water, and the piles can extend above ground. Driving tends to cause more noise and vibration than drilling, though this can be minimised with the right equipment. Options include:

  • Steel Cased Bottom Driven Piles — Because the energy is delivered directly to the toe, allowing for high efficiency, the machines can be relatively small and access confined spaces.
  • Steel Cased Grundomat Driven Piles — Powered by compressed air, the casing is injected in sections, each welded to the one before. This method causes less vibration than most driven piling.

All these methods offer the best option in different circumstances. Why not get in touch for a chat about what kind of piling would suit your needs?

When Do I Need Scaffolding?

If you ask whether you legally require scaffolding for a given job, you’ll get half a dozen self-styled experts each giving you a different answer. The regulations aren’t always precise, but understanding them will give you a firm guideline to what’s needed.


When Is Scaffolding Required?

The short answer to the question of when scaffolding is needed is when a thorough risk assessment concludes that it’s necessary. A risk assessment must by law be carried out on any job where any employees are working at height. It’s not a legal requirement when an individual is doing the work privately, but it’s common sense to take safety seriously.

Employees working at height (which isn’t clearly defined) must by law be safeguarded. For low-risk jobs, such as minor roof repairs to a domestic house, it might be considered safe to use a ladder, however we would always recommend utilising scaffolding or a working platform for Health and Safety reasons to increase stability and reduce the risk of accidents occurring. If you are planning to be working at height for a long period or moving about at height, then this is when it is imperative that you use a safer working platform such as an appropriately designed scaffolding system.


Why Is Scaffolding Necessary

Even when the law doesn’t specify it, there are numerous reasons why scaffolding is important. Anyone working at height for extended periods, especially in wet or windy weather, could be at risk of falling. Having a stable platform on a secure framework will reduce the risk to acceptable levels. Scaffolding also makes it easier to move around the building without having to constantly climb up and down.

In addition, scaffolding provides an easier means to tether tools and prevent a possible tragedy, since even a small tool falling from height could kill someone below. Besides common humanity, the safety aspect is a legal obligation for the person responsible for the site’s safety — often the contractor, but a business such as a property developer or landlord may have responsibility for work being done.


Properties That Can Use Scaffolding

Any building that’s being built, demolished or substantially repaired is likely to require scaffolding. The size doesn’t matter, nor whether it’s commercial, domestic or public.

A multi-storey office block being demolished will have scaffolding that’s dismantled from the top downwards as the building gets lower. If and when the promised repairs to Parliament get started, we’ll see the Palace of Westminster swathed in scaffolding. On the other hand, you might also need it for substantial work on the roof of your home.

The right scaffolding is available for all of these requirements. If you have any questions about scaffolding, feel free to get in touch with us.
