What Causes Wood Rot?

Forest rot is a form of decay triggered by the combination of moisture and fungi (microscopic organisms). In order for fungi to fix shop, the wood must exist continuously damp; fungi will not abound on dry out wood. Withal every bit many as 5 million types of fungi exist in the air and soil around us, and there's no escaping them. While many types, such as yeast and mushrooms, are beneficial, others are destructive. The numerous types that trigger wood rot are loosely classified past the three general furnishings they take on forest.

• Brown Rot: Often called "dry rot" considering the surface of the forest appears dry, brownish-rot fungi targets cellulose in the wood's structure. As the cellulose is destroyed, the wood shrinks, turns deep chocolate-brown in colour, and breaks into pocket-sized cube-shaped bits—a process known as cubical fracture. Brown rot thrives at temps between 65 and 90 degrees Fahrenheit, and once it starts growing, it spreads speedily.
• White Rot: If wood takes on a whitish or light yellow shade and feels spongy, it's probably white rot. Whereas chocolate-brown rot affects cellulose white-rot fungi break downwards lignin, another chemical element of the woods's structure, leaving the lite-colored cellulose backside. Like chocolate-brown rot, white rot occurs in temps between 65 and 90 degrees Fahrenheit.
• Soft Rot: Soft-rot fungi decompose woods more than slowly than brown-rot fungi and white-rot fungi, but thrive in temperatures too hot and too cold for the other types to survive, between 0 and 110 degrees Fahrenheit. Soft-rot fungi break downward cellulose, leaving the wood with a honeycomb-like appearance, and while it is usually plant in fallen logs and trees, not commonly in houses, it can strike a abode if conditions are right.

Where Is My Home at Chance?

Because woods rot occurs in damp areas that do non dry out, information technology often goes undetected until a remodeling project exposes it. The following areas are the nearly likely spots for wood rot to get a foothold.

Because the wood is not exposed to air or sunlight, it remains clammy—providing optimal conditions for fungi growth. Older wooden windows are at an even greater risk, every bit water tends to pool on the horizontal sills, seeping through cracks in the paint.
2. Exterior doors

3. Outdoor decks
   Horizontal decking boards and stair treads can also concur water. While many treated decking boards are water-resistant, they're not 100 percent waterproof, and over fourth dimension, they can rot. The bottoms of painted balusters are a prime spot for rotting; they're typically built from untreated pine, and then painted to resist the elements. Water becomes trapped nether the bottom of the baluster and doesn't dry out, giving fungi a chance to grow.
4. Basements
   High humidity and moisture is prevalent in basements because the physical walls are surrounded by moist soil. Humidity levels tin be then high in leaky basements that water vapor tin form on the surface of walls and wooden ceiling joists. Once woods rot gets a foothold here, it tin spread unnoticed until it creates structural impairment.
5. Wet rooms
   Whatever room with a plumbed water fixture, such as a kitchen, laundry room, bathroom, or utility room (with a water heater) is at risk. Leaks around water supply lines and bleed pipes keep the area wet and provide an optimal environment for wood-rot fungi to thrive.
6. Damaged roofing
   Missing or damaged shingles tin let water to seep in, and over time, it tin can lead to wood rot in the roof decking and in the lumber used to frame the attic.
