Port Orchard Crawl Space Encapsulation Yields Lasting Protection

The homeowner was in the process of completing several renovations and wanted a long-term solution that would improve energy efficiency, insulation, and moisture protection beneath the home. After scheduling a free crawl space inspection, we discovered the space had no insulation, uninsulated ductwork, and a vapor barrier that was loose and no longer providing adequate protection.

To create a cleaner, more durable crawl space, the homeowner chose to move forward with a full encapsulation. Our crew began by removing the existing duct insulation, old vapor barrier, and debris. Once the crawl space was cleaned and prepared, we installed foam board insulation, a reinforced white vapor barrier across the ground and foundation walls, and a dehumidifier to help control moisture year-round. We also installed first time batt floor insulation to improve the home’s energy efficiency and indoor comfort.

With plans to stay in the home for the foreseeable future, the homeowner invested in a permanent solution designed to protect the crawl space and provide lasting peace of mind.
