Before and After Pictures from New Haven
Crawl Space Encapsulation in New Haven, CT

Crawl Space Encapsulation in New Haven, CT

Before After
Crawl Space Encapsulation in New Haven, CT Crawl Space Encapsulation in New Haven, CT

Water used to seep through the walls and floor of this New Haven, CT crawlspace and cause mold, rot, and other moisture-related problems. To create a dry environment, we encapsulated the space with our CleanSpace vapor barrier on the floor and SilverGlo insulation on the walls. Water can't pass through either product! The encapsulation treatment totally separates and protects the crawl space interior from outdoor conditions, keeping the space clean and dry.

Crawl Space Sump Pump in New Haven, CT

During heavy rains, this crawlspace would flood with water. Because it lacked a drainage system, the water would sit in the space for weeks at a time. To pump water out of the crawl space and collect groundwater before it enters the home, we installed the SmartSump sump pump. Along with a cast-iron Zoeller sump pump, the SmartSump includes a floor drain to collect water from plumbing leaks and a WaterWatch sump pump alarm that will sound off to notify the owners of water in the crawl space. The homeowners can reast easy knowing that their crawl space wil stay dry, even in heavy rainstorms!

This old crawlspace used to leak through the walls and floor, causing mold to grow. To keep moisture out of the home, we put in our CleanSpace liner on the floor. This durable, bright white crawl space liner prevents water vapor and humidity from passing through. With a 25-year warranty against rips and tears, this durable liner will convert your crawl space into a usable storage area. And with its mold-resistant additive "UltraFresh", CleanSpace will never support mildew or mold growth on its surface.

Water Seepage Effects On New Haven, CT Home

Mary Ellen D. called Connecticut Basement Systems after finding water seeping into her basement through the foundation.  Though she was understandably concerned, Mary Ellen was also optimistic about finding a quick, long lasting solution.  Mary Ellen soon met with waterproofing specialist Thomas Gibson who knew exactly how to solve her problem. 

With Thomas’s recommendations, Al and his crew installed a SuperSump sump pump, UltraSump III sump pump, and an Ice Guard.  This would protect her basement from future flooding by not allowing the foundation water to continue to seep into her basement.  Next, a WaterGuard and LawnScape outlet were installed, which would effectively redirect any basement water into her yard.  Finally, a FloodRing was put in place to prevent any leaking due to her water heater.

Basement always has mold, better in winter, worse in summer, but it has gotten more extreme in the last three weeks. We have a de-humidifier there which we run most of the time, but it is old and needs to be replaced. But the new problem is not due to the dehumidifier because we used the same dehumidifier last year and the mold was more under control.
