Blackheath FAQs

Plywood Overlay Subfloor Prep in Blackheath — common questions

6mm or 12mm ply overlay in Blackheath?

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

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 SE3 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 Blackheath visit.

Can you lay LVT straight after overlay?

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