Crawlspace Encapsulation: A San Lorenzo Success Story

Crawlspace Encapsulation: A San Lorenzo Success Story

Before After
Crawlspace Encapsulation: A San Lorenzo Success Story Crawlspace Encapsulation: A San Lorenzo Success Story

Thomas, remodeling his San Lorenzo bathroom, discovered a hidden nightmare: a waterlogged crawlspace festering with mold. Years of unnoticed leaks had caused extensive damage, threatening both his home's structural integrity and his family's health. Ignoring a simple patch-up, Thomas took decisive action.

 

He reached out to us at Clean Crawlspace solution. Our expert moisture control specialist Daniel Griggs identified the source of moisture in Thomas’ crawlspace. Then our skilled installation crew came, installed a sump pump to permanently combat water infiltration, and sealed her crawl space using the innovative CleanSpace® Crawl Space Vapor Barrier system, creating a dry, durable, healthy environment that would prevent future mold growth.

 

Thomas was very happy that the transformation was immediate. This comprehensive approach converted the once-hazardous space into a clean, dry haven, safeguarding his home and ensuring the well-being of his loved ones. The remodel might have started above ground, but the true victory unfolded beneath the surface, where Clean CrawlSpace’s proactive measures preserved not just a bathroom, but another healthy home in beautiful San Lorenzo, California.
