What is Dry Rot?

Dry rot, or brown rot, is actually a fungal infection that damages wood and causes decay. Fungi are microorganisms that eat organic matter and absorb moisture to survive. Wood, which is an organic material, is perfect for many fungal species. Dry rot eats away at the wood, weakening its overall structure as the infection spreads to more and more of the surrounding wood.

How to Identify Wood Rot in your Crawl Space

One of the more concerning things about wood rot is the inability to easily identify the problem before it causes major damage. In the beginning, dry rot starts as tiny spores. These spores are invisible to the eye, but if enough gather in one spot, they can look like red, yellow, or brown dust.

Given the right conditions, mainly moisture and humidity, the spores mature and leave dry, crumbling wood behind. It was thought that dry rot didn’t need water to survive, hence the name, although that is not true, dry rot does need less water than other fungi to thrive.

How to Identify Wood Rot in your Home

When the wood in your crawl space is decaying, you’ll notice signs of damage upstairs as well. Unfortunately, these are all signs of structural failure and should be addressed by the experts at BQ Basements and Concrete as soon as possible.

Uneven, Bouncy or Sagging Floors

Spongey, bouncy or sagging floors are a major sign of crawl space problems. When a section of floor doesn’t feel solid beneath your feet, it’s an indication of wood decay. Floors that sag or slope towards the middle of the room are common problem signs for floors lacking in support, this could be because dry rot has stolen its strength.

Gaps Between Floor and Wall

Similar to sagging floors, when a homeowner notices a gap between the wall and the floor it’s an indication that your floor supports are failing to carry the load of your home. We recommend checking the crawl space for signs of damage right away.

Wall Cracks

When the beams that support the weight of your home begin to fall, the home sinks or sags unevenly, this puts pressure on the walls causing cracks. It’s common for cracks to appear above doors or windows. When these signs are noticed contact BQ Basements & Concrete for an estimate.
