FREQUENTLY ASKED QUESTIONS
Your Questions About Dry Rot & Wet Rot Answered
Dry rot and wet rot can both cause serious structural problems if ignored. Here are answers to some of the most common questions about rot treatment across Northern Ireland.
1. What’s the difference between dry rot and wet rot?
Dry rot spreads quickly through timber and masonry, even without visible damp. Wet rot stays confined to areas with constant moisture, such as leaking roofs or floors.
2. What causes rot in timber?
Rot is caused by fungal growth that feeds on damp wood. It often results from leaks, rising damp, or poor ventilation.
3. How do I know if I have dry rot?
Look for cracking or crumbling timber, a musty smell, and white or grey fungal growth with orange spore dust.
4. How do you treat dry and wet rot?
We remove infected timber, apply fungicidal solutions, and correct the source of damp to stop the fungus from spreading or returning.
5. Can dry rot spread through brickwork?
Yes. Dry rot can travel through porous masonry to reach new timber, which is why professional treatment is essential.
6. How long does rot treatment take?
Most treatments are completed within a few days, depending on the level of decay and structural repairs required.
7. Will I need new timbers installed?
In many cases, yes. Severely damaged wood is replaced with treated, rot-resistant timber.
8. Are your treatments safe and guaranteed?
Yes. All treatments use approved, safe fungicides and come with long-term guarantees for your assurance.
