Wood Rot

Northern California homes face a silent threat that jeopardizes their foundations: wood rot. This fungus deteriorates all wooden supports, leading to sagging floors and poor structural integrity.  

Moist conditions common in Oakland, Sacramento, and San Jose contribute to this issue, putting entire homes at risk. 

Crawl space encapsulation from Bay Area Underpinning eliminates the conditions that cause wood rot.  

This page explores how to identify, prevent, and repair crawl space wood rot to safeguard your property. 

What is Wood Rot?

Wood rot, caused by a fungus known as Serpula lacrymans, causes significant damage to wooden structures by breaking down the cellulose in wood, impacting foundation support beams and other critical elements.  

If left unaddressed, it can lead to sagging floors, uneven surfaces, and compromised indoor air quality. It may also signal additional problems like mold growth, pest infestations, wet insulation, and persistent musty odors.  

Wood rot occurs in moisture-rich areas, including crawl spaces, basements, attics, decks, and around leaky pipes. Failing to address the underlying problems of causes significant structural damage.  

If you suspect wood rot in your crawl space, contact a professional for an inspection to maintain your home’s safety, health, and value. 

What Causes Wood Rot?

Wood rot requires two elements for growth: organic material (wood), and persistent moisture. There are several conditions that create an environment conducive to wood rot, including: 

Wood rot spreads quickly in damp, dark, and confined crawl space areas. Without effective moisture control, this fungus continues to deteriorate wooden components.
