Asbestos in pre-2000 homes
A black pad sits under a stainless-steel sink and it was not sampled. Why must the survey not declare that pad free of asbestos?
The survey must not declare that pad free of asbestos, because it was not sampled. A black pad under a stainless-steel sink is often a bitumen sound-deadening layer, and buildings built or refurbished before 2000 can contain asbestos in materials of that kind. Looking at the colour does not identify it. The home survey has recorded an unsampled pad left in place. It has not had the material tested, and it has not called the pad safe or unsafe.

What is the fuller explanation?
A home survey is not an asbestos survey. It does not sample by looking, and the pad should be left undisturbed rather than opened up to see what is inside. The pad is there to quiet the steel bowl. That job does not name the fibres. Until a competent person samples it properly, asbestos has not been ruled out and has not been confirmed. A new-looking sink does not date the pad underneath it. The report has issued no clearance.
Tell the solicitor there is an unsampled black pad under the sink and that the survey has not cleared it. If you need to know the material, instruct someone competent to sample it, and leave the pad undisturbed. Do not let a kitchen fitter pull it off as part of an ordinary quote. The home survey has not named the material. It has not said the pad may be treated as free of asbestos.
What should you ask your surveyor?
- Was the black pad under the sink left unsampled?
- Has the survey refused to call that pad free of asbestos?
- Is the finding limited to what could be seen without disturbing it?
What are the typical next steps?
- Treat the pad as untested for asbestos.
- Leave it undisturbed unless a competent sampler is instructed.
- Do not let a fitter remove it as ordinary kitchen work.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.

If the sink is new, must the pad be new and clear?
No. A new stainless bowl can be set on an older pad, and the survey has not dated either. The pad was not sampled. Buildings built or refurbished before 2000 can contain asbestos, and looking at a black layer does not rule that out. The report has not declared the pad free of asbestos, whatever the bowl looks like.
Can you wipe the pad and then call it checked?
No. Wiping is not sampling, and a home survey does not identify asbestos by eye. The pad should be left undisturbed. A competent person, if you instruct one, takes a sample under proper controls. Until that result exists, the survey's position stands: the pad has not been declared free of asbestos.
