Asbestos in pre-2000 homes
Black spots of old adhesive remain where vinyl tiles were lifted. Why is that residue still a materials question?
Because those black spots of old adhesive are still on the floor, the residue remains a materials question after the vinyl tiles were lifted. Lifting the tiles did not identify what was left behind. HSE says asbestos can be present in buildings built or refurbished before 2000, and floor finishes are among the places materials vary. The home survey can note black spots. It has not analysed them. The spots are not cleared because the tiles themselves have gone.

What is the fuller explanation?
Adhesive left as dots looks like a decorating nuisance, which is why people grind it off before a new floor goes down. Grinding is disturbance of a material that has not been named. The survey's limit is visual: old adhesive, black, where tiles were lifted. That sentence keeps the question open. It does not say the residue is asbestos, and it does not say it is not. Until someone competent identifies it, it stays a materials question rather than a patch of dirt.
Tell any floor layer that the spots are not to be scraped, sanded or heated off as part of measuring the room. If identification is required, that is a competent person's instruction, not a multitool on viewing day. Do not bag a few spots yourself to 'help the lab'. The tiles being gone changes the surface you can see. It does not retire the question the black residue still poses.
What should you ask your surveyor?
- Are the black spots recorded as unidentified adhesive, not as dirt?
- Did lifting the tiles include any test of what was left?
- What should not be ground off before the residue is identified?
What are the typical next steps?
- Keep the black adhesive spots as a materials question.
- Do not scrape, sand or heat them off while you measure.
- Ask someone competent to identify the residue before floor works.
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.
Also asked about this
If the spots are only in a cupboard, can they be ignored?
No. A cupboard is still a place the black residue remains. The survey has not identified those spots, wherever they sit, so they stay a materials question.
Does a new laminate over the spots answer the question?
No. Laminate covers the spots. It does not identify the adhesive, and the materials question stays under the new floor until someone competent has looked.
