  • Underlay choice

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

  • Doorway transitions

    Most 1930s bay-fronted semis doorways here need a bevelled bar rather than a Z-bar to clear the carpet next door.

Blackfen FAQs

Plywood Overlay Subfloor Prep in Blackfen — common questions

6mm or 12mm ply overlay in Blackfen?

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

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 DA15 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 Blackfen visit.

Can you lay LVT straight after overlay?

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