Sidcup FAQs

Plywood Overlay Subfloor Prep in Sidcup — common questions

Can you lay LVT straight after overlay?

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

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 Sidcup visit.

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 DA14/DA15 overlay job.

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