Dry Rot of Wood Causes, Remedies, and Prevention
Dry rot of wood is a serious issue that can cause extensive damage to homes and other structures. It is a type of fungal decay that affects the structural integrity of wood, leading to decay, weakening, and eventual failure. In this blog post, we will explore what dry rot is, how it occurs, and most importantly, how it can be corrected and prevented.
I. Understanding Dry Rot
Dry rot, scientifically known as Serpula lacrymans, is a wood-destroying fungus that thrives in damp and poorly ventilated environments. Unlike wet rot, which requires high levels of moisture, dry rot can develop in timber with moisture content as low as 20%. It commonly affects softwoods, but can also infest hardwoods under favorable conditions.
II. Causes of Dry Rot
Dry rot occurs due to a combination of three key factors: moisture, suitable temperature, and a food source (wood). When these conditions align, dry rot spores germinate, and hyphae (root-like structures) grow, gradually consuming the wood. Common causes of moisture intrusion include plumbing leaks, faulty gutters, rising damp, and inadequate ventilation. Once the wood becomes damp, the fungus can thrive, even in hidden areas.
