Crawl Space Encapsulation

Crawl space encapsulation for the Bay Area including Santa Rosa, Sonoma Napa, Marin, Concord, Hayward, Oakland, Pleasant Hill, San Leandro, Walnut Creek, Vallejo, Lafayette, CA, and the surrounding areas homes is often the best solution for crawl spaces that are not already water damaged. Crawl spaces are inherently moisture-problem areas due to their lack of ventilation and flat concrete surfaces, both of which give excess humidity nowhere to escape.

If you don’t know what “encapsulation” means, it is the process of applying a moisture barrier to all exposed surfaces of the crawl space. If done properly, it can prevent any further formation of moisture levels. When excess humidity becomes trapped in a space, it can cause mold and attract pests, contribute to wood rot, poor indoor air quality, increased radon gas levels, and many other problems.

Our crawl space encapsulation experts will help you combat these issues while increasing your home’s energy efficiency! By protecting your home from moisture damage, you can save money on your energy bills over time. It also protects the home’s structure from the damage that moisture causes, which can result in repair costs.

Crawl Space Moisture Barrier

Many crawl spaces are full of dust, dirt, and debris that can also damage your flooring. These particles are often kicked up into the air when you walk into the room above.

If this debris gets stirred up too much, it can cause respiratory problems in your home. Sealing your crawl space can create a moisture barrier to prevent this dust and dirt from coming up into the room.

The crawl space encapsulation process begins by creating a vapor barrier on all exposed surfaces in your crawl space. We apply spray foam in order to seal any possible area where moisture could seep through.

This can be especially important if you live in areas where the difference between indoor and outdoor humidity levels is high. There are certain times of the year when humidity can become very high, causing your crawl space to be even more humid.

If you suspect that your crawl space is venting this excess humidity inside, you should make sure there are no holes or unsealed spaces for it to escape through. You may also want to add a dehumidifier. This is relatively inexpensive and can keep your humidity levels in a healthy range.

Encapsulating a crawl space not only helps prevent potential future damage but enhances the indoor air quality in your home by eliminating excess humidity.
