Crawl Space Encapsulation in New Haven, CT

Crawl Space Encapsulation in New Haven, CT

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.

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.

Job Stories From New Haven, CT
Wet Basement Troubles in New Haven, CT

When Philip and Ellie S. found water in their basement, they wanted the problem solved as soon as possible.  They contacted Connecticut Basement Systems in the hopes of finding an efficient way to solve their problems.  Soon after, they met with waterproofing specialist Jack Henriques, who came up with a plan to end the couple’s misfortune once and for all.

In the time span of a single day, Gomes and his crew came in to the New Haven home and installed a Trench Drain and Water Guard system combo to combat and eliminate the water in their basement.  With those two in place, a SuperSump sump pump was installed in order to prevent future flooding in the basement.  Finally, a SaniDry dehumidifier was installed in order to combat and eliminate moisture for a full circle solution to their basement water issues. 

 Phillip and Ellie were so happy with the work in their basement, that they purchased solutions for their crawl space before that became an issue as well.  The basement is now a drier and safer place to be in, and Connecticut Basement Systems will be returning soon to make sure their crawl space is never a source of stress either! 

WaterGuard And SuperSump Help Keep New Haven, CT Home Dry

When Jeremy N. found that his window wells were leaking water into his basement, he needed a permanent solution to his situation.  He began researching companies online, ultimately choosing Connecticut Basement Systems to solve the problem for him.  Soon after, Jeremy met with waterproofing specialist Rick Raucci who figured out a plan to solve Jeremy’s basement troubles.

Cisco and his crew arrived at the New Haven home and installed a Trench Drain, Waterguard system, and port to effectively eliminate the water in the basement and be able to routinely test the system. Along with this, the SuperSump sump pump, TripleSafe sump pump, Ice Guard system, and lateral feedlines were also installed.  With these additions, it ensured that no matter what the season or weather condition, future flooding would not happen.

Three months later, Jeremy called Connecticut Basement Systems to repair an unrelated leak in his basement.  With these improvements, Jeremy’s basement is no longer a place of concern and is a drier and safer environment in his home. 

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.

After effectively protecting her basement, Mary Ellen knows that Connecticut Basement Systems is a reliable source for any of her future problems!  Her basement is no longer a place of concern and is a drier and safer environment!

I recently bought a house built around 1870. There is considerable slanting throughout the first and second floors, but I was aware of it and not concerned. I had several contractors look at the house and they assured me that the house is not still settling. I attempted to hire a structural engineer prior to buying the house but was not able to. Now the floors seem to be buckling more and there are cracks in the corners of the walls, I don't know how much of this is typical for an old home?
