Dry Rot & Wet Rot Treatment in Merthyr Tydfil
Dry rot (Serpula lacrymans) is one of the most serious timber defects a property can suffer. Unlike wet rot, dry rot can spread through masonry and travel significant distances from its moisture source — rapidly destroying structural timbers and plaster as it goes. Wet rot (Coniophora puteana) is more common and confined to the immediate damp area, but still causes serious structural damage to joists, rafters, and floorboards. Both require specialist treatment: fungicide application, removal of infected material, and — most importantly — elimination of the moisture source. EverDry Damp handles the full remediation from survey to reinstatement.

Frequently Asked Questions — Dry Rot & Wet Rot in Merthyr Tydfil
How quickly can dry rot spread?
Dry rot can spread at a rate of several millimetres per day under ideal conditions, travelling through masonry and across large areas of a property. Early identification and treatment is critical — delays significantly increase the cost and scope of remediation.
What is the difference between dry rot and wet rot?
Dry rot (Serpula lacrymans) is the more serious — it can spread through masonry and is not confined to the original wet area. Wet rot remains in the immediate damp zone and will stop if the moisture source is removed. Both require treatment but dry rot demands a much more thorough remediation.
Do I need to move out during dry rot treatment?
In most cases no, though we may need to restrict access to treated areas for 24–48 hours while fungicide treatments cure. We discuss the programme with you before work starts to minimise disruption.
