  • Erith subfloor reality

    Riverside flats sometimes flag damp — we use a meter before guaranteeing any glue-down vinyl.

  • Underlay choice

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

  • Doorway transitions

    Most victorian and post-war terraces doorways here need a bevelled bar rather than a Z-bar to clear the carpet next door.

Erith FAQs

Plywood Overlay Subfloor Prep in Erith — common questions

6mm or 12mm ply overlay in Erith?

6mm for most residential rooms; 12mm where joists are wide or boards are particularly uneven. Standard 6mm on Victorian bedroom fits in Northumberland Heath.

Will overlay stop floor squeaks?

Yes — ring-shank nails on 150mm grid pin the ply and the boards below to the joists. Standard on every DA8 overlay job.

How much height does it add?

6–12mm plus underlay for the new decorative floor — usually 10–20mm total. Doors may need trimming, we factor that in on the Erith visit.

Can you lay LVT straight after overlay?

Yes — ply overlay is fit-ready the same day. No moisture cure required (unlike latex screed).
