Dry rot

This fungus causes decay primarily under conditions of restricted ventilation, and high humidity. Dry rot can remain active in timber down to 20% moisture content and can attack dry timber. The fungus can grow throughout the fabric of the building if conditions are suitable. It can penetrate through brickwork and masonry, and behind plaster, decaying the timber in its path. Decaying timber develops 'cuboidal' cracking, and is usually overgrown by masses of grey-white mycelium. Plate-like fruiting bodies produce millions of rusty-red spores (seeds) as a reddish dust. These spores spread the fungal infection to other sites.

Wet rot

There are numerous types of wet rot, although not as serious as dry rot is still a common cause of structural defects in buildings.

However when the moisture source is removed, activity of the fungal growth ceases, although by this stage timbers may have become structurally weakened.

Heritage Preservation (Remedials) Ltd will undertake a detailed remedial survey. If evidence of fungal decay (dry/wet rot) is found a full report and recommendation will be submitted, detailing necessary timber replacement/treatment required for the eradication of the fungal decay.
