Sealing your crawlspace offers numerous benefits, enhancing both your home’s health and indoor air quality. Our tailored solutions, including CrawlBarrier®, closed-cell spray foam, and Bora-Foam® Rigid Foam Board, ensure a sealed, clean environment, safeguarding against mold, pests, and odors while enhancing your living space’s comfort and health.
This option starts with removing and hauling away the existing fiberglass insulation. We then air-seal the subfloor which separates the living space above from the crawlspace by sealing all penetrations with foam spray. New polyethylene vapor barrier (options for 10-mil, 10-mil reinforced, 12-mil reinforced, or 16-mil reinforced) is installed on the crawlspace ground; set it in place with heavy-gauge galvanized liner staples, full roll-ups on the foundation piers, roll-ups on the perimeters walls (will be subsequently sealed sealed to the walls with the Spray Foam), and vapor barrier tape on all foundation piers and panel seams.
We then seal with crawlspace with 2″ closed-cell spray foam applied to the crawlspace exterior wall and rim joists. The still plate and 3″ below the still plate remain exposed for future termite inspections.
Once sealed, we install air induction, a dehumidifier, or a combination of both in order to extract residual air moisture from the crawlspace.
Spray Foam is needed for very uneven foundation walls or foundation walls that are only single-brick width (which can be damaged by insulations requiring mechanical fasteners). It does, however, cost more than CrawlBarrier and does use chemicals which require the home occupants to vacate the home when the spraying begins and for 24 hours after the spraying is completed.
