Damp & Dry Rot

One of the biggest threats to structural timber is fungal decay. Both wet rot and dry rot, united in their love of damp, can cause serious structural damage to your home.

What is dry rot?

Dry rot to wood is like kryptonite to Superman. Serpula lacrymans is the technical term for this fungus that can reduce stalwart beams, joists and timbers to crumbling, hazardous structures. In spite of its name dry rot needs moisture to thrive, in fact it needs wood with a moisture content of at least 20%. It loves damp, warm, unventilated conditions so it’s often found in areas that aren’t easily visible such as roof trusses, the underside of wooden floors, beneath stairs and behind skirting boards.

What is wet rot?

More common than dry rot, wet rot is caused by a fungus called Coniophora puteana, aka the ‘cellar fungus’. This type of fungus is only attracted to very damp wood or plaster and unlike dry rot, remains confined to the wet area only. It’s generally deemed less destructive than dry rot but serious cases can prove hazardous to a building’s structure.

Rising damp, condensation or penetrating damp?

Rising damp, penetrating damp and condensation are the three most common types of damp that can affect your home. Each of them needs to be treated in different ways, so use the image gallery below to find out which type of damp or mould is affecting your home.

After identifying the type of damp you have, read on to find out what could be causing it. Living in a property with mould can be bad for your health, so you’ll want to get it sorted as soon as possible.

The worse the situation gets, the more it will cost you to remove.
