What Is Dry Rot?
Dry rot is a type of fungal decay that attacks timber when moisture levels are high and ventilation is poor. Unlike wet rot, dry rot can spread beyond timber into masonry, plaster, and brickwork as it searches for new moisture sources. Left untreated, it weakens structural timbers such as floor joists and roof beams, causing serious safety and financial risks.
Signs of Dry Rot
You may have dry rot if you notice:
- White or grey, cotton-wool-like growth on timber
- Rusty-brown patches on wood
- Cracked, cuboid-shaped patterns in timber
- Musty or damp odours in affected rooms
- Shrinking, brittle, or crumbling wooden structures
If you spot any of these signs, it’s essential to book a professional survey quickly before the damage spreads further.
How Dry Rot Affects Your Property
Dry rot doesn’t just damage timber — it threatens the entire structure of your property:
- Structural weaknesss – sagging floors, leaning walls, and roof instability
- Costly repairs – decayed joists and beams often require full replacement
- Health concerns – spores released into the air can aggravate asthma and allergies
- Property value – untreated dry rot can deter buyers and reduce sale price

I spoke to James over the phone when their workers were doing some work at my neighbours. He was very clear and prompt with his response. Then I booked an appointment for him to visit my property to inspect for rising damp. James arrived within the time span given and was very patient in explaining the problem and gave us a quote within the time scale he promised. His pricing is reasonable and quote has clear explanation of what would be done and what is the requirement from us. We have now decided to go ahead and complete the work with them. Excellent communication & customer service so far.![]()
