What happens when timber gets damp? Timber that stays above roughly 20% moisture content becomes vulnerable to fungal decay — wet rot in persistently damp wood, dry rot when conditions allow — and to wood-boring insects like woodworm. Treatment involves fixing the moisture source, drying the timber, treating with preservatives, and replacing wood that has lost structural strength.
Signs of timber damp in your home
Caught early, timber damp is far cheaper to fix. If you recognise any of these, it’s worth getting a local expert to take a look — our advice is free.
- Soft, spongy wood — skirtings, joists or window frames that give when pressed
- Dark staining — discoloured timber, often with a damp, earthy smell
- Springy or bouncy floors — floor joists losing strength below the boards
- Small round exit holes — woodworm flight holes with fine dust (frass)
- Cracked, cuboidal timber — wood breaking into cubes — a dry rot warning
- Fungal growth — strands, cotton-wool mycelium or mushroom-like fruiting bodies
What causes timber damp?
Building timbers stay healthy for centuries when dry. Problems start when leaks, rising damp, condensation or poor sub-floor ventilation push moisture content up — creating ideal conditions for wet rot, dry rot and wood-boring beetles.
Sub-floor voids with blocked airbricks are a classic Sussex case: trapped humid air slowly soaks joists from below, and the first sign many owners notice is a bouncy floor. Catching it at the 'treat and dry' stage costs a fraction of replacing structural timber.
Not sure this matches what you’re seeing? Book a local damp survey and we’ll diagnose it properly — survey fees are discounted from any work you go ahead with.
How we treat timber damp
Timber & damp survey
We inspect accessible timbers, measure moisture content and identify decay type and the moisture source feeding it.
Fix the moisture
Leaks, damp and ventilation problems are corrected — no timber treatment lasts if the wood stays wet.
Treat & replace
Affected timbers are treated with professional preservatives; structurally weakened wood is cut out and replaced.
Protect long-term
Preventative treatment and ventilation improvements protect remaining timbers, backed by our guarantee.
Every job protected for 30 years.
All timber damp works are completed by checked & vetted local specialists and come with a 30-year guarantee — so you can fix it once and forget about it.
