Crawl Space Encapsulation

Have you noticed increased moisture, high utility bills, or a musty odor in your home? These signs could warn of hidden issues lurking beneath your living space. 

Many Northern California homes have crawl spaces due to the area’s hilly terrain and seasonal rain. When properly maintained, this foundation area improves your home’s environment. Keeping the crawl space dry prevents mold growth, protects against wood rot, and enhances indoor air quality and home efficiency.

How We Encapsulate a Crawl Space

Securing a safe, clean, and dry crawl space requires attention to detail. At Bay Area Underpinning, our experts recognize the importance of each step in this transformative process and execute every installation phase with precision. Our comprehensive approach ensures a healthier living environment and enhances your home’s energy efficiency.

Control Ground Water Seepage

What We Do

Water from rain and snow saturates the soil beneath your home. Without proper drainage, this can cause standing water in your crawl space. Over time, water in the crawl space creates an environment conducive to mold and wood rot, both of which can damage your home’s structural integrity. 

At Bay Area Underpinning, we provide an industry-leading crawl space drainage system. Crawl space drainage captures and diverts groundwater. In turn, it safeguards your home from damage, addresses one of the root causes behind moisture issues, and makes your home healthier overall.

What We Use

Change the Environment

What We Do

We seal your crawl space with an industrial-grade vapor barrier to protect it from moisture, transforming and controlling the environment. This barrier prevents moisture from entering through open vents, foundation wall gaps, and other openings. Bay Area Underpinning’s crawl space encapsulation solutions achieve a healthier, more stable home.

What We Use

Properly Insulate the Crawl Space

What We Do

Leaving your crawl space uninsulated is like leaving your front door open all winter. Exposing a crawl space and subfloor to the elements leads to cold floors and high energy bills as the heating system works overtime. Bay Area Underpinning installs moisture and mold-resistant crawl space insulation panels to keep your home warm and reduce energy costs.
