Crawl Space Encapsulation Company Serving Richmond, Williamsburg, Henrico & Nearby

Before encapsulating this crawl space, we treated the joists with an antimicrobial called Shockwave. This product is a hospital-grade antimicrobial designed to kill the mold and mildew growth. 

Moisture and high humidity in this crawl space resulted in mold and mildew growth and damage to the insulation. The homeowner wanted to encapsulate the space, so our team set to work cleaning out the crawl space, air sealing vents, the rim band, sill plate, and any other openings through the foundation wall to the outside. They treated the microbial growth with an antimicrobial, installed a new CleanSpace Vapor Barrier, applied Foam Board insulation to the foundation walls, and installed a dehumidifier to regulate the relative humidity. 

After sealing and insulating this crawl space, we need to make sure we control the relative humidity. This is achieved by installing a dehumidifier with a hygrometer. The dehumidifier will be set to cut to on when the humidity reaches about 55% our goal is to prevent it from getting high enough that microbial growth can occur in the crawl space. We don't want the space to be too dry either because that can be damaging to the home's structure as well. A hygrometer is provided to the homeowner that allows them to monitor the temperature and relative humidity in the crawl space from inside their home. 

This homeowner in Montpelier was having moisture issues within the crawl space of their home. As a result of the excessive outside influence, their home was uncomfortable and the energy bills were high. We encapsulated their crawl space using a CleanSpace Light vapor barrier to help seal off the earth's moisture from the crawl space. Then, we sprayed an inch and a half of closed-cell R-10 spray foam over the foundation walls. All penetrations and vents are also sealed, and the spray foam acts as an air barrier and vapor retarder, protecting the crawl space from the outside influence. With their crawl space encapsulated and insulated, the homeowner should enjoy a much more comfortable home with lower energy bills.

This Bruington, VA client contacted us about repairing moisture damage in their crawl space. Moisture had caused mold and mildew growth, was absorbed in the insulation which held it against the floor joists, the material began to delaminate and fall away from the floor. 

All debris and insulation was removed from the crawl space, microbial growth was treated, the vents, sill plate, & rim band were sealed, the foundation walls were insulated with closed cell spray foam insulation and a dehumidifier was installed to control the relative humidity. The homeowners no longer need to worry about moisture damage in their crawl space and have the added benefit of warmer floors in the winter and reduced drafts in the home.
