Subfloor preparation · Strood, ME2
Floorboard preparation explained for Strood homes, from re-securing boards to deciding when a plywood overlay is also needed.
Floorboard preparation ranges from a straightforward re-screw of loose boards through to more involved work where boards are damaged, badly cupped or need partial replacement. What is required depends entirely on the condition found once carpet or an old floorcovering is lifted.
Suspended timber floors under Victorian terraces in Strood need ventilation checked as well as levelness, since a damp void below causes problems no amount of surface work solves.
| Condition | Typical approach |
|---|---|
| Occasional squeak, boards otherwise sound | Screw down at joist positions |
| Gaps between boards under 3-4mm | Screw down, accept minor gaps under most coverings |
| Wider gaps or draughts | Consider overlay or filling before fitting |
| Cupping or bowing across several boards | Overlay usually needed to give a flat surface |
| Damaged, rotten or missing boards | Individual replacement, structural check if extensive |
Older {town} properties with original timber floors often have a mix of board ages and past repairs, so each area gets checked individually rather than assumed to be consistent throughout the room. A board that feels sound in one spot can be loose only a metre away.
Uneven hallway floors are a recurring theme in Cuxton, usually where an old quarry tile floor was skimmed over rather than properly levelled years ago.
Narrow rear access off the Cuxton in parts of Strood means preparation materials sometimes have to be carried through rather than driven to the door, which we plan for in advance.
Postcode district ME2, Medway Council.
Boards that have been lifted repeatedly for plumbing or electrical access are often the loosest in the room, since repeated lifting widens the fixing holes each time. These boards are usually refixed with new screw positions rather than reusing the same worn holes, giving a more secure result.
We reach Strood via the M2 Junction 2, and cover the wider ME2 district as part of our normal round.
Our in-house fitters secure boards at the joists so the noise and movement actually stop.

Decide whether re-fixing alone is enough or whether a plywood overlay is needed for a flat, stable surface.
Walk the floor to confirm no squeaks or movement remain before fitting the new floorcovering.
Confirm airbricks and under-floor ventilation paths remain clear once work is complete.
Boards that are split, rotten, or too badly damaged to hold a secure fixing are replaced individually rather than screwed back down, since a weak board will not provide a stable base.
Proper preparation should not block under-floor ventilation. Airbricks and ventilation gaps are kept clear to prevent damp building up beneath a suspended timber floor.
Yes, generally. Screws hold far better against the repeated flex that causes movement and noise, whereas nails can work loose again over time, especially in boards that have already moved once.
Gaps usually form as timber shrinks over time, particularly in older properties or where heating has dried the boards out further. Small gaps are often accepted under carpet, while wider gaps may need filling or an overlay before resilient flooring.
Screwing boards down properly at the joists, replacing damaged sections, and checking ventilation gives a stable base for whatever flooring is fitted on top.
