What should I say if I do not know what is under the floor?
“Unknown layers” is a useful and honest answer. Do not lift, scrape or sand a finish simply to complete an enquiry. The visible surface can hide earlier coverings, adhesives or repairs that need assessment before disturbance.

Separate the decisions
Describe only what you already know from records or exposed areas that are safely visible. A previous owner’s description is background information, not a material identification. Older materials can require specialist assessment; appearance alone cannot establish whether a layer is safe to disturb.
What to explain next
Ask how the scope will handle uncertainty and who will decide if unexpected layers change the work. Your new-floor installer should also explain what surface they need afterwards. Keeping these questions open is better than requesting “everything down to concrete” without confirming the assembly.
An example, not a completed job
Put the uncertainty into words
“The visible floor is laminate. We have no record of the layers below it and have not lifted a section. Please allow for assessment before confirming removal depth.”
- Which layer is actually visible?
- Are there reliable renovation records?
- Who reviews newly exposed material before further work?
Choose your next step
Use the short enquiry, or organise what you know in the optional three-step planner. You can leave uncertain details for assessment. The form does not accept attachments.
