We Provide Complete Crawl Space Waterproofing Solutions
We’ll start with a free, no-obligation inspection. We’ll evaluate your crawl space for water entry points, structural damage, condensation issues, and air leaks. We’ll discuss the current state of your crawl space and make recommendations for long-term protection.

Vapor Barrier Installation: Our crawl space waterproofing services in St. Matthews, KY, include expert installation of a high-density polyethylene liner across the crawl space floor and walls. The design of the barrier blocks ground moisture from entering the airspace under your home, which significantly reduces the risk of mold and mildew, pest infestations, and structural wood rot underneath your living space.
Sump Pump Installation: We recommend sump pump installation to quickly and effectively move water out of your crawl space. We place a high-capacity pump in a designated sump basin at the crawl space’s lowest point. When the water level rises, the pump automatically turns on to remove it, helping prevent flooding and long-term damage. We also offer battery backup systems for added security during storms.
Sealing Vents and Air Gaps: Open vents and gaps allow humid outside air to flow in, which increases condensation and moisture problems. We seal these entry points to stabilize the internal crawl space environment. This step is especially important in St. Matthews, where summer humidity often reaches extreme levels for days at a time.
Dehumidifier System Installation: To regulate humidity in your crawl space year-round, we offer professional dehumidifier system installations. Our commercial-grade units are energy-efficient and maintain a relative humidity level below 60%, which discourages mold growth and enhances indoor air quality throughout your home.
Crawl Space Encapsulation: For full moisture protection, encapsulation is the gold standard in crawl space waterproofing services in St. Matthews, KY. This service transforms your crawl space into a sealed, conditioned environment. It combines vapor barriers, sealed vents, drainage systems, sump pumps, insulation, and a dehumidifier system for long-term peace of mind.

FAQs About Crawl Space Waterproofing in St. Matthews, KY
Here are answers to some of the most common questions that homeowners in St. Matthews, Kentucky, ask about crawl space waterproofing.
Can Waterproofing My Crawl Space Help Reduce Allergens in My Home?
Yes, waterproofing your crawl space helps to significantly reduce the likelihood of mold spores, dust mites, and pest-related allergens circulating into your living areas through your HVAC system or floor gaps.
Is Waterproofing Necessary for Homes With Concrete Crawl Space Floors?
Yes, homes with concrete floors still benefit from professional waterproofing. Concrete can allow water vapor to pass through; therefore, even crawl spaces with slab floors often need vapor barriers, dehumidification, and proper drainage.
