Asbestos in pre-2000 homes
Thermoplastic tiles in the porch were not sampled. Why must a visual note not declare them free of asbestos?
A visual note must not declare the porch tiles free of asbestos because they were not sampled. Thermoplastic tiles were seen, and seeing them is not a sample. Buildings built or refurbished before 2000 can contain asbestos, and a home survey does not sample it by looking. The survey has recorded the tiles and the fact they were not tested. It has not called them safe, and it has not called them unsafe. Free of asbestos is a laboratory answer. This note does not have one.

What is the fuller explanation?
Thermoplastic floor tiles are among the materials people ask about in older porches, and the only honest survey sentence is that they were not sampled. A glance cannot see asbestos fibres and cannot clear a product. The surveyor should not break a tile to settle the question, and neither should you. Sampling, if you need it, is a separate instruction to someone competent to take a sample and have it analysed. Until that exists, the visual note stays visual.
Tell the solicitor the porch tiles were not sampled and the survey has not declared them free of asbestos. If you need an answer, instruct a proper sample rather than a harder stare at the same tiles. Do not sand, drill, scrape, or break the tiles to find out. Keep any analyst's result, if you obtain one, separate from the visual note in the home survey.
What should you ask your surveyor?
- Which porch tiles were seen and not sampled?
- Why must a visual note stop short of calling them free of asbestos?
- Did this visit include any sample or analysis?
What are the typical next steps?
- Tell the solicitor the porch tiles were not sampled and are not cleared.
- Instruct a proper sample if you need an analysis.
- Do not sand, drill, scrape, or break the tiles to find out.
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 porch tiles look modern, may the visual note call them free of asbestos?
No. Tiles that look modern can still not be declared free of asbestos on a visual note, because they were not sampled. A home survey does not sample by looking. Buildings built or refurbished before 2000 can contain asbestos. Appearance is not an analysis, and the survey has not provided one.
Should a tile be broken off to settle whether asbestos is present?
No. Breaking a tile is not the way to settle it, and the survey has not asked you to. The tiles were not sampled. A visual note must not call them free of asbestos. If a sample is required, that is a competent person's job, not a fragment you knock off the porch floor.
