This Niantic home had constant water entering the basement and moisture was seeping through the walls. This was causing the home to become unpleasant with its dampness and musty odor. The homeowner wanted a clean, dry basement so she could utilize her space. She decided to call Connecticut Basement Systems to help find her a solution. 

The solution for this basement was to install a WaterGuard system paired with CleanSpace. The WaterGuard system will collect the water internally and channel it to the TripleSafe Sump Pump. (TripleSafe Sump Pump is seen in the after photo.) The water is then withdrawn from the sump pump and exits through the discharge line (white pipe in after photo.) This system will keep the basement dry. We also installed a CleanSpace liner to prevent moisture from seeping through the walls. With minimal moisture, the musty odor will be eliminated.  

Once all these products were installed, the basement transformed into a healthier and cleaner area. This is exactly what the homeowner wanted and was thrilled with the products and her transformed basement.

Two piers in the basement crawlspace are sinking or leaning causing portions of the home to become unlevel.

I had you do a job for me. No complaint about the workers or workmanship. I had mentioned upon talking with the sales representative that I wanted to use an HVAC system to condition the crawl space as well as the house. I have a vapor barrier and spray foam installed. Looking at your web site I had pictured an end result more like the Terra Foam and wall board. What is the cost to insulate? Can I install foam board over the vapor barrier? Would I be paying twice the cost as the vapor barrier is installed?

Looking at buying a house with a crawl space that has exposed plumbing, dirt floor, concrete block wall with vents and 2.5' height clearance . Presently has fiberglass between joists and 6 mill vapor barrier. Very damp. Got an estimate for spray foam on walls. Cheap, but does not seem effective enough. 1200 sq ft ranch. Beach cottage built in 1940 converted to house.

Vicinity of Woodland Drive in Niantic
I have a dirt crawl space under my cottage. One area is less than 6" from the grade and needs to be made - ideally at least 12". Aside from clearing the grade I need some type of drainage as the property slopes. Home has pier and post support system that needs repair. The beams are sagging. (Home is from 1927.) I need an additional support at midsection in addition to fixing sagging beams. Crawl space is not easily accessible for people. Am interested in your "crawl space science." In long run want a poured cement basement and to make cottage all year round.
