What is wet rot and is it serious? Wet rot is fungal decay in timber that stays persistently damp (above ~50% moisture saturation), most commonly Coniophora puteana (cellar fungus). It stays confined to the wet area — unlike dry rot it doesn't spread through masonry — but it will steadily destroy structural timber until the moisture source is fixed and the wood treated or replaced.
Signs of wet rot in your home
Caught early, wet rot 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 timber — wood that feels mushy and gives under a screwdriver
- Darkened wood — affected timber looks darker than the surrounding area
- Cracking along the grain — linear splits as the timber dries and shrinks
- Flaking paint on frames — painted timber hiding decay beneath — probe it
- Damp, musty smell — earthy odours near affected wood
- Localised fungal growth — dark brown strands or thin sheets on damp wood
What causes wet rot?
Wet rot needs one thing: timber that stays wet. Leaking gutters soaking fascias, failed window sills holding rainwater, plumbing leaks under sinks, rising damp at joist ends and condensation in sub-floor voids are the usual suspects we find across Brighton's housing stock.
Because wet rot only lives where the moisture is, the repair logic is simple — stop the water, and the rot stops with it. That's also why painting over decayed frames or filling soft wood never works for long: the moisture is still there underneath.
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 wet rot
Confirm wet rot & its source
We identify the decay type (wet rot vs dry rot matters enormously) and trace the moisture feeding it.
Eliminate the moisture
Gutter, roof, plumbing, damp or ventilation problems are fixed so timber can dry below decay threshold.
Treat & repair timber
Decayed timber is cut out and replaced; surrounding sound timber is treated with fungicidal preservative.
