Dry rot is a single species and is classed as a type of brown rot that requires only 28% moisture content in wood in order to start growing. Despite the name of the fungi, it will not materialise when there is no moisture in the atmosphere, although looks and acts differently from wet rot.
There are a number of signs that may point to the presence of dry rot in the building, some more common than others. Some of the symptoms may include:
If you notice any of these signs in your building’s structure, you should waste no time in calling in a professional to diagnose and treat the problem area before serious damage sets in. Dry rot left untreated over a prolonged period of time has the potential to damage the timber structure beyond repair, requiring a complete replacement. Misdiagnosing dry rot as a wet rot can be a very expensive mistake!
The primary solution to dry rot is to control the environment that is allowing its growth. The cause of the dampness needs to be identified and fixed to remove the source of water.
Poorly ventilated rooms suffering from condensation should be fitted with additional ventilation, such as extractor fans and/or sub-floor vents, which are services Garratt’s offer.
The next step is to eradicate the rot – removal and replacement of the affected timber and masonry. Any timbers that remain in place will need irrigating and sterilising.
Dry rot is a type of fungi that attacks timber in order to feed, destroying the cellulose and lignin of the wood in the process. This results in weakening of the timber and if left unchecked, it can severely weaken the timber’s structural integrity. This may result in full replacement timber being required.
Wood rots can affect all types of building, both old and new. Dry rot in London buildings and properties thrives in damp, moist environments, particularly areas where there is poor ventilation which is common in older buildings and basements. The rot appears as a fleshy ‘fruiting body,’ comprised of vegetative fibrous mycelium. In order for dry rot to form, there must be water/moisture in the atmosphere and a food source (timber).
Spores of dry rot germinate in the pores of the timber, resulting in vegetation that feeds upon the timber before spreading to produce a fruiting body. This fruiting body will release more spores and the cycle will continue.
The timber structure will begin to shrink and crack, become brittle and take on a darker colour. But beware, as these signs are also typical of wet rot. With dry rot, the shrinking of the timber will create cuboidal cracking – the depth of this cracking is greater in dry rot than wet.
Once identified, dry rot should be treated as quickly as possible to prevent further spreading and weakening of the affected timber.
The Cause:
The treatment for dry rot varies depending on the severity of the outbreak. In order for our team to be able to offer a definitive quotation, we would need to be able to inspect the property.
