Asbestos in pre-2000 homes
Thermoplastic tiles are stuck with a black adhesive and neither the tile nor the adhesive was sampled. What has a visual note not identified?
The visual note has not identified whether the thermoplastic tile or the black adhesive contains asbestos. Neither was sampled. A black adhesive under this kind of tile is a familiar suspect appearance in older floors. Appearance is not an identification. The survey recorded the tiles and the adhesive it could see. It has not named the material, and it has not cleared it. Buildings built or refurbished before 2000 can contain asbestos. Looking does not sample it.

What is the fuller explanation?
Thermoplastic floor tiles and the bitumen adhesives used with them are among the products that get asked about in pre-2000 homes. The survey can describe colour, size and the black bed. It cannot say the tile is asbestos, and it cannot say the adhesive is not. Both sentences would be identifications, and no sample was taken. A home survey does not become an asbestos survey because the adhesive looks dark. The limit of the note is exactly that: seen, not identified.
If the floor is to be lifted, ask an asbestos surveyor about sampling before the tiles are disturbed, and tell the solicitor the home survey has not identified them. Do not describe the black bed as a known material. Leave the covering in place rather than treating a visual note as a reason to rip it out. The report has not cleared the floor and has not condemned it.
What should you ask your surveyor?
- Were both the thermoplastic tiles and the black adhesive left unsampled?
- What did the visual note record, short of an identification?
- Did you avoid calling either material asbestos or free of it?
What are the typical next steps?
- Treat the tile and the adhesive as unidentified.
- Ask an asbestos surveyor before the floor is disturbed.
- Do not read a black adhesive as a laboratory result.
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 a later kitchen has modern sheet flooring, are these tiles cleared?
No. Another room's new floor does not sample these tiles or their adhesive. The survey saw thermoplastic tiles in a black bed and identified neither. Buildings built or refurbished before 2000 can contain asbestos, and a visual note does not clear a different covering. Each material stands on its own sample, which was not taken here.
Does a firm tile that does not crumble change the identification?
No. How a tile feels underfoot is not a sample. The survey did not identify the thermoplastic tile or the black adhesive. Condition of the surface does not show what either product contains. Leave them undisturbed. An asbestos survey is the route to identification, not a judgement from the sole of a shoe.
