Complete Crawl Space Transformation: Why It’s the Key to a Healthier Home
Encapsulating a home’s crawl space makes the home a healthier place to live and breathe
Reason #1: To Protect Against Mold
Reason #2: To Improve Indoor Air Quality
Studies in building science reveal that approximately 40% of the air we breathe within our Cary homes originates from the crawlspace. Vented crawlspaces typically harbor poor-quality air laden with mold, mildew, rust, wood rot, deteriorated fiberglass insulation, pest residue, dust, pathogens, and natural vapors emanating from decaying organic matter in the soil. This compromised air infiltrates the living spaces through the stack effect and leaks in the HVAC ducts and components installed in the Cary crawlspace.
Sealing the crawlspace in your Cary, NC residence regulates relative humidity, effectively curbing the growth of mold, mildew, rust, and other harmful elements. With encapsulation, fiberglass insulation becomes unnecessary and can be removed, eliminating it as an air quality obstacle. Furthermore, encapsulation prevents pests like insects, rodents, and snakes from accessing your home. A high-quality crawl space vapor barrier provides additional protection against noxious vapors.
To combat foul odors, we apply a natural deodorization spray in your Cary crawlspace, comprising non-pathogenic bacteria and enzymes designed to consume decaying organic matter. Ultimately, a well-sealed crawlspace ensures the elimination of poor-quality air, directly enhancing the indoor air quality of your living space.
If your existing fiberglass insulation is in good shape, we can seal the crawlspace with CrawlBarrier®
Crawl Space Encapsulation Option #1: CrawlBarrier®
Our process commences with the installation of a polyethylene crawl space vapor barrier on the crawlspace ground of your Cary residence. We offer various options for the vapor barrier, including 10-mil, 10-mil reinforced, 12-mil reinforced, or 16-mil reinforced, all surpassing the strength of 6-mil products mandated by building codes. The vapor barrier is secured in place using heavy-gauge galvanized liner staples, meticulously rolled up at the foundation piers, and along the perimeter walls. Subsequently, it is sealed to the walls using CrawlBarrier® and taped at all foundation piers and panel seams.
Next, we mechanically fasten CrawlBarrier® to the perimeter walls of the crawlspace and meticulously tape all panel seams. To further seal the space, we utilize foam board and foam spray to seal the foundation vents.
By employing CrawlBarrier® along the crawlspace perimeter walls, we effectively seal off the space from outside air. To regulate residual moisture, we introduce either air induction or a dehumidifier as part of our conditioning process.
Crawl Space Encapsulation Option #2: Closed-Cell Spray Foam
Crawl Space Encapsulation Option #3: Bora-Foam® Rigid Foam Board
Option #3 follows a similar process to Option #2, albeit with a different sealing method. Instead of using 2” closed-cell spray foam, we employ BoraFoam® Rigid Foam Board to seal the crawl space walls of your Cary property.
BoraFoam® measures 2.5″ in thickness and is anchored into the crawlspace exterior wall using concrete anchors. The seams are meticulously taped with vapor barrier tape, while the edges are sealed with foam spray. Additionally, BoraFoam® is installed onto the rim joists and sealed with foam spray, leaving the still plate and the area 3″ below it exposed for future termite inspections.
This foam board is pre-treated with Borate, an anti-termite additive, and comes pre-laminated with 3-mil polyethylene vapor barrier attached on each side, totaling 6-mil accumulative thickness.
Compared to Spray Foam, BoraFoam® offers a cleaner appearance as it expands uniformly during application. Furthermore, being a cured foam board, it does not emit gases during installation, making it an ideal choice for Cary homeowners concerned about chemical exposure.
