Wet rot is fungal decay of timber that stays persistently wet — typically above 50% moisture content. Unlike dry rot, it stays confined to the damp area and cannot spread through masonry. Treatment is straightforward: eliminate the moisture source, remove decayed wood, and treat surrounding timber with fungicide.

What is wet rot?

Wet rot (most commonly Coniophora puteana, the cellar fungus) thrives wherever timber and constant moisture meet: window sills under failed paint, joist ends in damp walls, floors over wet sub-floor voids, and roof timbers under slow leaks.

The encouraging news is that wet rot is the "contained" rot — fix the damp and it stops. The risk is structural: a joist or lintel can lose most of its strength before the surface looks obviously bad. That's why professional assessment matters.

Signs of wet rot to look out for

  • Timber that feels soft and spongy when pressed
  • Darkened, localised decay in damp areas
  • Cracking along and across the grain
  • Flaky, blistered paint on affected wood
  • A damp, musty smell near the affected area
  • Visible fungal growth or thin dark strands

Spotting one or more of these? Don't wait — damp problems only get more expensive with time. Book a free survey and we'll tell you exactly what's going on.

How we treat wet rot

Step one is always the moisture: we trace and fix the leak, damp or condensation keeping the timber wet — whether that's penetrating damp, plumbing, or sub-floor ventilation. Step two: decayed timber is cut out and replaced or repaired with structural resin where appropriate. Step three: surrounding timber is treated with professional fungicide to prevent recurrence.

Everything is documented, COSHH compliant and backed by our written guarantee.

Wet Rot FAQs

Wet Rot — your questions answered

What's the difference between wet rot and dry rot?

Wet rot needs very damp timber and stays confined to the wet area. Dry rot is far more dangerous — it can transport moisture, spread through masonry, and colonise dry timber far from the original source. If you see rusty-red spore dust or grey strands, treat it as suspected dry rot and call us promptly.

Is wet rot serious?

It can be. While it spreads more slowly than dry rot, untreated wet rot will eventually destroy the structural strength of joists, lintels and floors. Early treatment is dramatically cheaper than structural repairs.

Can wet rot come back after treatment?

Only if timber gets wet again. Because we fix the moisture source as part of every wet rot job — not just the visible decay — recurrence is rare, and our guarantee protects you.

How much does wet rot treatment cost?

It depends entirely on the extent of decay and the repairs needed. After a free inspection you'll receive a fixed, itemised quote — typically far less than homeowners fear if the rot is caught early.
