Ply overlay subfloors across SE28
Old floorboards in a 1970s Peabody-era estates transitioning to mid-rise new-builds 1970s peabody estates in Thamesmead are the wrong base for LVT — every dip and gap telegraphs through. 6mm ply overlay, ring-shank nailed on a 150mm grid, gives you a mirror-flat base that doesn't squeak.
What plywood overlay subfloor prep in Thamesmead actually involves
Old floorboards in a 1970s Peabody-era estates transitioning to mid-rise new-builds 1970s peabody estates in Thamesmead are the wrong base for LVT — every dip and gap telegraphs through. 6mm ply overlay, ring-shank nailed on a 150mm grid, gives you a mirror-flat base that doesn't squeak.
Original 70s screed is often uneven — self-levelling latex is almost always needed for LVT.
What we check first on a Thamesmead subfloor prep job
- Stair nosings
Older Thamesmead stairs often have shallow treads — we re-cut grippers rather than force a standard kit.
- Doorway transitions
Most 1970s peabody estates 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 Thamesmead 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
