Keeping Pests Out with Crawl Space Fixes in Kensington, MD

When homeowners in Kensington, MD, discovered mice sneaking into their home through the crawl space, they knew it was time to take action. Their outdated crawl space door and a missing block vent were essentially open invitations for pests. These issues not only made the crawl space vulnerable to infestations but also to moisture and energy loss, creating a long list of potential problems. To address these concerns, our expert team got to work. The first step was cleaning out the crawl space to prepare it for a robust, long-term solution. We installed our CleanSpace® system to create a tough barrier that blocks moisture and prevents pests from entering. For added protection, we applied SilverGlo™ insulation, which not only improves thermal performance but also reinforces moisture control. We then sealed the crawl space completely with the installation of a sturdy EverLast door and a new block vent. The EverLast door is made from durable, mold-resistant material and provides an airtight seal to keep out pests and keep the crawl space protected. Together, these solutions transformed the crawl space into a safe, dry, and insulated environment. The benefits? The homeowners now enjoy a pest-free foundation, better energy efficiency, and peace of mind knowing their crawl space is fortified against future issues. This crawl space repair in Kensington, MD, is an excellent example of how our team combines effective products like the CleanSpace® system, SilverGlo™ insulation, and EverLast door to deliver exceptional results that last.
