What is the Difference between Wet and Dry Rot?


Rot is one of the most serious effects of damp that can damage buildings, causing serious issues to timber frameworks and should be treated as soon as possible to reduce the level of damage caused.

There are two main forms of rot that can affect buildings as a result of moisture in the timber; wet rot and dry rot. Although similar, the severity of these types of rot can vary – which can potentially cause irreversible damage if action is not taken. 

At Garratt’s Damp, we specialise in the treatment of both wet and dry rot in London and our team are on hand to advise and treat any issues you may be experiencing.

Treating Dry Rot in London

In London, as with many other built up areas across the country, the large volume of houses in close proximity can, unfortunately, mean that many homes are prone to issues with damp.

Dry rot is one of the most serious types of damp related problems and is difficult to identify on the account that it will usually form in secluded areas with heightened levels of moisture that cannot be seen. This often results in damage being made before a problem ever comes to light as rot can easily go unnoticed.

Particularly in London, dry rot surveys are extremely beneficial to landlords, homeowners and that looking into buying a property, especially as once the problem has been identified, it isn’t usually too difficult to treat. The first visible symptom of this is usually the appearance of red ‘dust’ and movement to timber floors, with dry rot forming on surfaces with high moisture readings.

From this, fruiting bodies will form and begin to penetrate surrounding areas and can eventually spread throughout the building if left long enough.

A Look at Wet Rot

This is the most common of the two types of rot, and often the easiest to treat. This is because wet rot will only penetrate damp areas rather than spreading through walls of its own accord. Wet rot will form in areas with around 50% moisture (requiring a far damper surface than dry rot) which is often much more noticeable.

If infected timber is left without treatment, this can result in major structural damage as the material becomes compromised. One of the most common causes of this form of damp is defective plumbing, leaking water onto the timber. Infected surfaces will begin to form a white substance not too dissimilar from the appearance of cotton wool.
