Bay Area Underpinning offers crawl space encapsulation for homes in the Bay Area. Our crawl space solutions prevent mold growth, insect infestations and radon from entering your home. We have certified installers that are fully trained to make sure the air quality in your home is healthy and safe for you and your family.

The structure of your home keeps it standing  and should be protected against outside elements such as humidity, moisture and air leaks. Moisture and humidity can weaken the structural integrity of your home and cause foundation problems and basement water issues. Encapsulating your crawl space to keep moisture out can also lower your utility bill and keep your home energy efficient. We offer free inspections for the residents in our service area.

Bay Area Crawl Space ProblemsThe first step to preventing moisture in your crawl space is to identify the source. The most common problems are caused by the following:

  • Plumbing leaks
  • Foundation cracks
  • Poor drainage
  • Clogged gutters and improper downspout extensions
  • High water table
  • Trees and shrubs planted too close to the foundation
  • Inadequate waterproofing

If your home has any of these issues, look for signs of water intrusion such as:

  • Wood rot
  • Condensation on insulation or water pipes
  • Musty or strange odors in the living area
  • Mold growth
  • Insect infestation
  • Water leaks or pooling water
  • Standing water in the yard
  • Buckling or warping upper level floors
  • Foundation cracks

If you notice any of these signs, contact our experts today and we will put a vapor barrier into your home's crawl space to lock moisture out of the area.

Solutions for a Healthy Crawlspace in the Bay Area

Crawl Space Encapsulation San Francisco CATo prevent water damage and control moisture in your crawl space, we can install a vapor barrier system. The vapor barrier consists of a 10-20 mil thick, puncture-free material that is designed to block water and vapors so the moisture cannot rot wood surfaces and promote mold and mildew growth.

We also offer sump pump and drainage system installation to make sure water is removed and does not seep into the liner of the crawl space. Sump pumps are installed in the lowest part of the home, which is usually in the basement, to divert water out of the home.

After installing a vapor barrier and sump pump, we dehumidify the crawl space and seal all exterior vents. This helps eliminate outside moisture from entering the crawl space and makes your home more energy efficient. The less humidity that is in your crawl space, the fewer issues you will have with mold growth, wood rot, and metal rust.

At Bay Area Underpinning, we can survey any interior and exterior damages in your home. If you have water damage, our experts can use helical piers to reinforce the joists and floor beams. They are designed to stabilize and support the weight of the foundation to increase the longevity of your home.
