Dry rot is one of the most serious forms of timber decay found in older and moisture-prone homes across Cheshire. It spreads rapidly, often hidden beneath floors, and can compromise the structural safety of your property if left untreated.
At Weather Wise Solutions Limited, we’re trusted specialists in diagnosing and treating dry rot in floor joists and subfloor timbers — using advanced systems from PAM Ties and working to the standards of the Damp Proofing Association and Federation of Damp.
🔍 What Does Dry Rot Look Like?
Signs of dry rot in floor joists include:
-
Cracking or shrinking of timber with a brittle, cube-like texture
-
Distinct orange/brown fungal growth (Sporophore)
-
A musty, damp smell beneath the floor
-
Grey or white cotton wool-like mycelium
-
Paint blistering or discolouration on skirting boards or flooring
