Ply overlay subfloors across SE9/BR7

What plywood overlay subfloor prep in Mottingham actually involves

Cottage estates often have thin chipboard upstairs — checked for deflection before laying laminate or LVT.
Before we quote a subfloor prep job in Mottingham
- Stair nosings
Older Mottingham stairs often have shallow treads — we re-cut grippers rather than force a standard kit.
- Doorway transitions
Most 1920s cottage-estate terraces 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 Mottingham bedrooms; 10mm PU on stairs to stop bounce.
- 6mm or 12mm ply overlay for old floorboard subfloors
- Ring-shank nailed on 150mm grid — no squeaks
- Perfect base for LVT, laminate, vinyl and wood
- Alternative to full screed on suspended floors
Bottom line: LVT over old floorboards is a mistake. Ply overlay first, LVT second.
