Moisture in Crawl Space

Crawl spaces might be out of sight, but they are responsible for keeping your house stable and healthy. Excessive moisture in these areas causes significant trouble.

Even though where we serve in Northern California is mostly dry, moisture still affects your home during unusually humid days. Bay Area Underpinning helps homeowners in Oakland, Sacramento, and San Jose address crawl space moisture with comprehensive encapsulation methods.

What is Crawl Space Moisture?

Moisture in your crawl space refers to any water, whether liquid or vapor, present beneath your home. While some moisture is normal, too much can harm your home. Here’s what could happen:

Moisture degrades indoor air quality and compromises structural integrity.

How Does Moisture Get into a Crawl Space?

Most crawl spaces are built in a way that allows moisture to enter beneath your home. This is due to old building codes and out-of-date construction methods.

Here’s the most common way moisture infiltrates a crawl space:

Crawl spaces are close to the ground and usually have damp, dirty floors.
Rainy days or humid air can seep into the crawl space through open vents.
When cool surfaces in the crawl space mix with warm outdoor air, condensation forms below your home.
Moisture can enter if plumbing lines start to leak.
If drainage on your property (gutters or yard grading) is faulty, water is likely to flow under the crawl space.

It’s crucial to identify these issues early to keep your home safe and sound. If you notice problems, contact us immediately to avoid further damage.
