Practical damp subfloor assessment across SE10/SE3

a free site survey

Floor coverings can fail when moisture is trapped below adhesive, vinyl or laminate. In Greenwich, the survey starts with the existing floor and the georgian and victorian period homes common locally, so the recommendation is based on the actual substrate rather than a generic product list. We check the visible symptoms, identify the floor build-up and take appropriate moisture readings before recommending preparation.

What damp subfloor assessment in Greenwich actually involves

Floor coverings can fail when moisture is trapped below adhesive, vinyl or laminate.

Period properties have suspended timber and lath ceilings below — no aggressive sanding.

Before we quote a subfloor prep job in Greenwich

  • Stair nosings

    Older Greenwich stairs often have shallow treads — we re-cut grippers rather than force a standard kit.

  • Doorway transitions

    Most georgian and victorian period homes doorways here need a bevelled bar rather than a Z-bar to clear the carpet next door.

  • Underlay choice

    8mm crumb is the usual call for Greenwich bedrooms; 10mm PU on stairs to stop bounce.

Greenwich FAQs

Damp Subfloor Assessment in Greenwich — common questions

What should I send before a Greenwich visit?

A few room photographs, approximate dimensions and a note about the current floor are enough to help us bring relevant samples and tools.

Can preparation and installation be handled together?

Yes. We check the visible symptoms, identify the floor build-up and take appropriate moisture readings before recommending preparation. Where both are needed, they are planned as one job rather than leaving separate trades to resolve the join.

Will you explain alternatives before materials are ordered?

Yes. The result may be extra drying time, a suitable moisture-control system or a different floor specification; it should never be guessed. The quote separates preparation from the chosen finish so the scope is clear.

Can you quote accurately from photographs?

Photos are useful for an initial conversation, but floor levels, moisture, movement and hidden damage need an on-site check before the final quotation.
