Gapping solid wood floor in Dalgety Bay — properly diagnosed
Solid wood moves — that's not a defect, it's the material. But when boards in Dalgety Bay start showing 5mm winter gaps, something is off in the humidity or ventilation of the room, and the fix isn't always filler. We start with a two-week humidity log, check underfloor ventilation, then decide between stabilising the room, re-laying in a stable month, or sliver-filling for character.
Common across KY11 — modern new-build housing here shows this pattern most often.
From £280 humidity survey + treatment plan; re-lay from £22/sqm
Diagnostic 1 day, remedial work 1–4 days

Wood floors move with humidity — chasing every gap without stabilising the room is money badly spent.
Symptoms we look for
Match two or more of these and it's very likely gapping wood boards.
- 01Visible gaps between boards, often 2–8mm wide
- 02Cupped edges — plank sides higher than centres
- 03Board ends lifting near external walls
- 04Squeaks that only appear in dry winter months
What causes it
Room humidity swinging outside the 40–60% comfort band
New central heating in an unaerated period property
Boards fitted too dry (or too wet) at install
Missing air-bricks under the joists — no ventilation
Affects: Solid oak · Solid pine · Original Victorian pine boards

How we fix it
- 1
Log room humidity for 2–3 weeks — establish the swing
- 2
Check underfloor ventilation and clear or install air-bricks as needed
- 3
Reversible-solutions first: humidifier / dehumidifier in season
- 4
For >4mm gaps — lift and re-lay tight in a stable month, or fill with matched slivers on Victorian floors
- 5
Refinish with an oil rather than lacquer to allow seasonal movement
Where DIY goes wrong
Filling with rigid wood filler — cracks out within one season
Sanding cupped boards flat before they've stabilised — leaves them thin and dished
