Uneven subfloor in Dalgety Bay? Fix it before the new floor goes down
Uneven subfloors are the single most common reason cheap flooring fails inside two years — and Dalgety Bay's off-level screed pours from the 80s and 90s are all classic culprits. We survey the floor properly, latex-level or sister-joist as required, then quote the finished floor — never the other way round.
Common across KY11 — modern new-build housing here shows this pattern most often.
£8–£16 per sqm for latex levelling; joist repair from £180
1 day for levelling + 24hr cure, before the finish floor goes down

Fitting hard flooring over an uneven subfloor is the #1 cause of premature failure — most warranties are void if it's out of spec.
Symptoms we look for
Match two or more of these and it's very likely uneven subfloor.
- 01New laminate or LVT clicks apart at the joints within months
- 02A marble rolls visibly across the floor
- 03Uneven wear stripes across an old carpet
- 04Doors that catch or scrape in one corner of the room
- 05Skirting boards showing a widening gap along one wall
What causes it
Screed poured off-level in 1970s–90s builds
Sagging joists in period properties
Localised damp or historic settlement
Old thermoplastic tile beds still in place under carpet
Affects: Concrete slab · Screed · Chipboard deck · Original pine boards

How we fix it
- 1
Survey with a 2m straight-edge and long spirit level, mapping the low points
- 2
Grind or scarify high spots on concrete/screed
- 3
Latex self-levelling compound (SLC) to bring the whole floor within tolerance
- 4
For timber decks — sister-joist or over-board with 18mm ply as required
- 5
Only then quote the finished floor — LVT, laminate, engineered wood or carpet
Where DIY goes wrong
Buying the wrong SLC grade — some need primer, some crack on flex
Levelling without addressing the underlying cause (damp, joist rot)
