Before we quote a subfloor prep job in Petts Wood
- Stair nosings
Older Petts Wood stairs often have shallow treads — we re-cut grippers rather than force a standard kit.
- Doorway transitions
Most 1930s mock-tudor detached 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 Petts Wood 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
