Fairfax, California, homeowner Joey K.'s dream turned damp due to a neglected crawlspace harboring mold, rodents, and their health-threatening droppings, urine, and saliva. (Potential health risks include the spread of diseases like hantavirus, leptospirosis, salmonellosis, tularemia, as well as triggering allergies or asthma attacks.)

 

The professionals at Clean Crawlspace were called in, evicting unwanted tenants, encapsulated the crawlspace walls and floor using the innovative CleanSpace® Crawl Space Vapor Barrier system to prevent moisture from entering. Finally, they installed a smart sump pump in the crawlspace's lowest point to pump away any water that does manage to get inside. 

 

Now, Joey's crawlspace is a serene haven, free from pests and moisture. Joey breathe’s easy knowing his home in Fairfax, California, is a haven of health.

Crawl space needs insulation and vapor barrier.
Project Location: Fairfax, CA
We had a mold inspector come out and he recommended the following in his report: Signs of historical flooding in the crawl space soil. Exposed soil in the crawl space, we recommend installation of an encapsulation system to cover the soil; Encapsulation uses a heavy duty polyethylene barrier to cover the entire crawl space, and foundation walls. The barrier is most effective if sealing tape is used to connect the overlapping barrier pieces, as well as being attached to the foundation walls. Once the area is sealed, based on your crawl space RH and moisture level, you may need to add a dehumidifier, extraction fan and or sump pump. If not present, we also recommend adding subfloor insulation which will add an additional barrier to moisture, vapors, MVOC's and mold entering the interior living area. Missing subfloor insulation system. We recommend installation of insulation with a vapor barrier to help prevent moisture and mold from entering the living areas, and to improve energy efficiency of the home. Inadequate ventilation of the crawl space, we recommend correction.
