Summer is the busiest time of year for home improvement projects. Across Liverpool, Wirral, Chester and the wider North West, homeowners use the warmer months to start extensions, loft conversions, garage conversions and larger renovation projects.
But many older properties still contain hidden asbestos-containing materials, and building work is one of the most common ways asbestos is accidentally disturbed.
Many asbestos-containing materials remain stable for years, but renovation work can quickly release harmful fibres if those materials are disturbed. Once fibres become airborne, they can spread throughout the property, creating serious disruption, unexpected costs and potential health risks.
That is why arranging an asbestos survey early in the project is so important.
What do new extensions have to do with old asbestos
Asbestos was widely used in UK homes throughout much of the twentieth century, particularly in properties built or refurbished before 2000. Because it was valued for its insulation, fire resistance and durability, it became part of countless everyday building products.
The problem is that extension and renovation work often involves cutting into exactly the areas where asbestos may still be hidden. This commonly includes:
- Garage roof sheets and wall panels
- Artex and textured ceiling coatings
- Vinyl floor tiles and adhesives
- Pipe lagging and boiler insulation
- Soffits, gutters and cement boards
- Asbestos insulating board (AIB) around partition walls, ceilings and service ducts
Many homeowners have no idea these materials are present until work has already started.
What Is a Refurbishment & Demolition Asbestos Survey?
A refurbishment and demolition (R&D) asbestos survey is designed for renovation, extension and structural alteration work.
Unlike a standard management survey, it focuses on the specific areas that will be disturbed during the project, including hidden spaces behind walls, ceilings and flooring where asbestos-containing materials may be present.
The aim is to identify asbestos before work begins so builders and homeowners can plan safely, avoid delays and prevent accidental contamination.
What to do before your extension starts
- Confirm your property age.
If it was built or significantly refurbished before 2000, treat asbestos as a real possibility, even if the inside looks modern. - Arrange a refurbishment and demolition survey of the affected areas.
Do this before contractors are appointed and before any stripping out begins, so the findings feed into the plan. - Have suspect materials tested.
Samples should go to a UKAS accredited laboratory for confirmation, so you get clear answers rather than guesswork. - Act on the findings.
If asbestos is found, it can be safely removed or managed before your build continues. Some materials require a licensed contractor, others do not, and a specialist will advise which applies. - Get clearance before reoccupation.
After any removal, air monitoring and a clearance check confirm the area is safe.
What the law actually requires before you build
If a property was built before 2000, asbestos should always be considered before intrusive refurbishment work takes place.
Under UK health and safety regulations, anyone carrying out building, refurbishment or demolition work has a responsibility to prevent asbestos exposure. This applies not only to contractors and tradespeople, but also to homeowners overseeing renovation projects.
Many builders and contractors will now recommend an asbestos survey during the planning stage, particularly in older homes. Identifying asbestos early helps prevent unexpected disruption later in the project and protects everyone working on site.
Across Liverpool, Wirral, Chester and the wider North West, we regularly work alongside homeowners, builders and project managers to help renovation work start with a clear understanding of the building before structural alterations begin.
What happens if you skip it
Most asbestos problems we are called out to could have been avoided with a survey at the planning stage.
Once asbestos-containing materials are disturbed, fibres can spread far beyond the immediate work area, settling on surfaces, furnishings and clothing throughout the home. At that point, work often has to stop while the property is professionally cleaned, tested and cleared, causing delays, additional costs and major disruption to the build schedule.
For many homeowners, what started as a straightforward summer extension quickly becomes a far more stressful and expensive problem than expected.
Quick questions
Can builders start work before an asbestos survey?
If a property was built before 2000, builders should not begin intrusive refurbishment work until asbestos risks have been properly assessed. Identifying asbestos before work starts helps prevent accidental disturbance, delays and potential contamination.
Is an asbestos survey needed for a loft conversion?
In many cases, yes. Loft conversions can disturb asbestos-containing materials such as textured coatings, insulation board, cement water tanks and older pipe lagging hidden within roof spaces.
Can asbestos delay a house extension?
It can if asbestos is discovered after work has already started. Arranging a survey during the planning stage helps avoid unexpected stoppages, decontamination work and costly delays later in the project.
What happens if asbestos is found during renovation?
Work should stop immediately until the material has been assessed. Depending on the type and condition of the asbestos, it may need to be safely removed, encapsulated or managed before the project continues.
Do garage conversions require asbestos surveys?
Older garages are one of the most common locations for asbestos-containing materials, particularly within cement roof sheets, wall linings and soffits. A refurbishment survey is strongly recommended before conversion work begins.
Do I legally need an asbestos survey before an extension?
A private home is not bound by the same duty to manage asbestos that applies to commercial premises. However, the work must not disturb asbestos without it being identified first, and your contractors have legal duties under CAR 2012. In practice this means a refurbishment and demolition survey of the areas being worked on is the responsible and expected step before any building begins.
What type of survey do I need for an extension?
A refurbishment and demolition survey. A standard management survey is not designed for construction work, because it does not look into the parts of the building that an extension will disturb.
My house was built in the 1980s. Could it still contain asbestos?
Yes. Asbestos was used in UK construction right up until it was fully banned in 1999. Homes from the 1980s and 1990s can still contain it, even if they look modern inside.
Will a survey delay my build?
A focused survey is quick to arrange and carry out, and it usually only needs to cover the areas affected by your works. Booking it during your planning stage means it sits comfortably ahead of your start date rather than holding anything up.
Do I need to survey the whole house or just the extension area?
Usually just the area being worked on. For a single storey extension, garage conversion, or loft conversion, the survey can be scoped to the part of the property being changed.
How much does an asbestos survey cost?
The cost depends on the size and scope of the works being surveyed. Contact Fibre Safe for a tailored quote based on your specific project, and we will explain exactly what is included.
