Does Your Drywall Contain Asbestos? Here’s What You Need to Know Before You Test
Drywall installed before the year 2000 could contain asbestos — and that is not a risk worth guessing at. Whether you are renovating an older property, managing a commercial building, or simply concerned about what is lurking behind your walls, a proper drywall asbestos test is the only way to know for certain. The problem is that too many people approach this process incorrectly, putting themselves and others at serious risk in the process.
This post walks you through the most common mistakes made when testing drywall for asbestos, how to avoid every one of them, and what a professional testing process actually looks like from start to finish.
Why Drywall Is a Genuine Asbestos Risk
Asbestos was widely used in construction materials throughout the twentieth century, and drywall products were no exception. Joint compounds, textured coatings, and the board itself could all contain asbestos fibres — particularly in buildings constructed or refurbished before 2000.
When drywall is cut, sanded, or drilled, it can release microscopic fibres into the air. These fibres are invisible to the naked eye and, once inhaled, can cause serious diseases including mesothelioma, asbestosis, and lung cancer. Symptoms can take decades to appear, which is precisely why so many people underestimate the danger.
If your property was built or refurbished before 2000, treat any drywall as a suspect material until a qualified professional confirms otherwise. Do not assume it is safe simply because it looks intact or undamaged — visual inspection alone tells you nothing about what is in the material.
Mistake 1: Skipping Proper Protective Equipment
One of the most common errors people make when attempting a drywall asbestos test is skipping personal protective equipment (PPE). It might seem like a minor inconvenience, but the consequences of getting this wrong are severe and potentially irreversible.
At a minimum, anyone collecting a sample from a suspect material should wear:
- A correctly fitted FFP3 respirator mask — not a standard dust mask
- Disposable nitrile gloves
- Disposable overalls or old clothing that can be bagged and disposed of safely afterwards
- Eye protection
The Control of Asbestos Regulations sets out clear legal obligations around protection from asbestos exposure. These rules exist for a reason — asbestos fibres are hazardous even in small quantities, and no test result is worth risking your health over.
Professional surveyors follow strict PPE protocols on every single visit. Any credible asbestos testing kit will include guidance on the minimum protective equipment required before you touch anything.
Mistake 2: Using Uncertified or Poor-Quality Testing Kits
Not all testing kits are created equal. There is a wide range of products on the market, and cheaper options can give unreliable results — either missing asbestos that is present or generating false positives that cause unnecessary alarm and expense.
A reliable drywall asbestos test kit should include:
- Appropriate PPE for safe sample collection
- Clearly labelled, sealable sample containers
- Step-by-step instructions for correct sampling technique
- Prepaid packaging for laboratory submission
- Analysis by a UKAS-accredited laboratory
The laboratory analysis itself matters enormously. Polarised light microscopy (PLM) is the standard method used to identify asbestos fibres in bulk samples. Laboratories accredited to ISO/IEC 17025 by UKAS are the benchmark you should look for — this accreditation means the lab’s methods have been independently verified as accurate and consistent.
Supernova’s testing kit is designed with exactly these standards in mind, giving you confidence that your results are reliable and legally defensible.
Mistake 3: Disturbing the Material Before or During Sampling
This is where many DIY attempts go badly wrong. People assume that to test drywall for asbestos, they need to cut or break off a chunk — and they reach for a saw, grinder, or hammer without thinking about what they might be releasing into the air.
Power tools are particularly dangerous when used on suspect materials. They generate significant quantities of fine dust, which can carry asbestos fibres throughout a room and beyond. Once fibres are airborne, they can settle on surfaces, clothing, and furnishings, creating a contamination problem far harder to manage than the original sample collection.
The correct approach involves:
- Dampening the surface lightly with water before sampling — this suppresses fibre release
- Using a sharp knife or scalpel to take a small, controlled sample
- Placing the sample directly into the container without shaking or handling it excessively
- Sealing the area with plastic sheeting if there is any doubt about contamination
- Disposing of all PPE and tools safely after sampling
If the drywall is in poor condition — friable, crumbling, or already damaged — do not attempt to sample it yourself. Contact a licensed professional immediately. Disturbing friable asbestos-containing material without proper controls is not just dangerous; it may breach your legal duties under the Control of Asbestos Regulations.
Mistake 4: Choosing the Wrong Sample Location
Where you take your sample matters just as much as how you take it. A drywall asbestos test is only meaningful if the sample is representative of the material you are concerned about.
Taking a sample from a freshly painted surface, a repaired section, or an area that has been previously disturbed may not give you an accurate picture of what is in the original material. For drywall specifically, you need to consider each distinct layer and component:
- The board itself — some older boards contained chrysotile (white asbestos) in the gypsum mix
- Joint compound — one of the most commonly identified asbestos-containing materials in older drywall systems
- Textured coatings and artex — applied over drywall, these frequently contained asbestos fibres
- Skim coats and plaster finishes — particularly common in commercial properties
A professional surveyor will assess the entire system and take samples from the most relevant locations. If you are unsure which part of your drywall to test, a management survey is the most thorough way to identify all suspect materials across a property and assess the risk each one presents.
Mistake 5: Ignoring the Legal Framework
Many property owners — particularly those managing commercial or rented premises — do not realise that asbestos management is not optional. The duty to manage asbestos is a legal requirement under the Control of Asbestos Regulations, and it applies to anyone responsible for non-domestic premises.
This duty includes identifying asbestos-containing materials (ACMs), assessing the risk they present, and putting a management plan in place. Simply testing one wall and forgetting about the rest does not satisfy this obligation.
Key regulations you need to understand
- Control of Asbestos Regulations — the primary legislation governing asbestos work in Great Britain, covering licensing, notification, and worker protection
- HSG264 – Asbestos: The Survey Guide — the HSE’s definitive guidance on how surveys should be conducted; professional surveyors follow this on every job
- Regulation 4 (Duty to Manage) — requires owners and managers of non-domestic premises to identify ACMs, assess risk, and maintain an asbestos register
Failure to comply can result in significant fines and, more critically, harm to building occupants and workers. A proper survey provides the documentation you need to demonstrate legal compliance.
When a DIY Drywall Asbestos Test Is Not Enough
A drywall asbestos test using a sampling kit can be a useful first step for homeowners who want a quick answer before deciding whether to proceed with renovation work. But there are situations where a DIY approach simply is not appropriate.
You should always use a professional surveyor when:
- You are planning significant renovation work — a refurbishment survey is legally required before any work that could disturb suspect materials
- The material is already damaged, friable, or visibly deteriorating
- You are managing a commercial, industrial, or rented property
- You need results that are legally defensible for insurance, sale, or regulatory purposes
- Multiple materials are suspect across the property
- You are planning to demolish all or part of a structure — a demolition survey is a legal requirement before any such work begins
If you have previously had a survey carried out, a re-inspection survey may be needed to check whether the condition of known ACMs has changed — particularly if there has been any building work, damage, or deterioration since the original survey was completed.
What Happens After You Get Your Results?
If your drywall asbestos test comes back negative, you can proceed with confidence — but keep the report on file. Circumstances change, and having documented evidence of a negative result is useful if the property is ever sold, let, or subject to further works.
If it comes back positive, do not panic. The presence of asbestos does not automatically mean it needs to be removed. Asbestos in good condition that is not being disturbed can often be managed safely in place, with regular monitoring to track any deterioration.
When removal becomes necessary
Where removal is necessary — for example, before renovation work that would disturb the material — this must be carried out by a licensed contractor. Supernova’s asbestos removal service connects you with licensed professionals who follow all HSE requirements for safe removal and disposal.
For commercial properties, it is also worth considering whether a fire risk assessment is due alongside your asbestos management — both are legal requirements for many premises, and addressing them together is often more efficient and cost-effective.

Frequently Asked Questions
How do I know if my drywall contains asbestos?
You cannot tell by looking at it. The only way to confirm whether drywall contains asbestos is to have a sample analysed by a UKAS-accredited laboratory. If your property was built or significantly refurbished before 2000, treat all drywall, joint compounds, and textured coatings as suspect materials until testing confirms otherwise.
Can I carry out a drywall asbestos test myself?
For homeowners, a DIY sampling kit can be a practical first step — provided you follow all safety precautions, wear appropriate PPE, and use a kit that sends samples to a UKAS-accredited laboratory. However, if the material is damaged, if you are managing a commercial property, or if you are planning renovation or demolition work, you should always use a qualified professional surveyor.
What types of asbestos are found in drywall?
Chrysotile (white asbestos) is the most commonly identified type in drywall boards and joint compounds. However, amosite (brown asbestos) and crocidolite (blue asbestos) have also been found in some construction products from the same era. Laboratory analysis under polarised light microscopy can identify the specific fibre type present.
Is asbestos in drywall always dangerous?
Not necessarily. Asbestos-containing materials that are in good condition and are not being disturbed pose a lower risk than damaged or friable materials. The danger arises when fibres are released into the air — typically during cutting, sanding, drilling, or demolition work. A professional surveyor will assess the condition of the material and advise on whether management in place or removal is the appropriate course of action.
What should I do if my drywall asbestos test comes back positive?
A positive result does not automatically mean the material needs to be removed. Your next step should be to speak with a qualified asbestos surveyor who can assess the condition of the material and advise on risk management. If removal is required — for example, ahead of renovation work — it must be carried out by a licensed contractor in accordance with the Control of Asbestos Regulations and HSE guidance.
