Job Stories From Westbrook, CT
Sanidry XP Installation in Westbrook, CT

This Westbrook, CT homeowner was looking for a new solution to the moisture seeping into her basement. She gave us a call at Connecticut Basement Systems, and we were happy to come on out! 

Our System Design Specialist, Matt Kraus, came out to the property and gave this family a solution he knew would positively affect their basement, making for a much more pleasant and energy efficient. Our expert foreman, Allan Guglielmoni, and his team came in, and quickly went to work! They first installed our SaniDry XPThis unit is industry best for dehumidifying a basement, offering 10x the performance of household dehumidifiers while using the same amount of energy. We also went ahead, and insulated the basement's rim joist. The rim joist is an area often overlooked when it comes to home insulation, and it is also a huge source of energy loss. When closed cell spray foam insulation is used, it cures dense and hard and is heavier than open cell foam. It forms an effective barrier against both moisture and air. 

This family can find relief in knowing their paid air won't go to waste, and that unwanted air will no longer sneak into their basement. Give us a call for your FREE energy evaiuation today!

After 23 yeqrs of being dry, all the rain this year has caused my basement to turn into an indoor pool 3x since January. The water table is very high and I expect the water is just coming in through the concrete floor. I would like advice on how to prevent this from happening again. Thanks!

Considering purchase of a home in Westbrook. Living room addition has unsupported floor (over 2-3ft crawlspace) and needs 3 concrete piers added (one at each end and one in middle @ 8ft apart) and support beam installed. Looking for rough estimate for this work. You are the only contractor I'm contacting.
Project Location: Westbrook, CT
Our garrison colonial is 53 years old and we have lived here for 46 years. Recently, we have experienced basement flooding (less than 1/4 inch) after very heavy rains. It appears that our yard now directs rainfall into puddles around our foundation and cellar hatch. Our basement is essentially a warehouse of accumulated stuff; and removing the water is a major chore with resulting mold/mildew problems as well. Our house is approximately 1600 square feet; with a full basement , attached garage and newer family room over a crawl space.

Water in the basement, sump pump is running every 5 minutes
Project Location: Westbrook, CT
We have a sump pump that is three years old and when I checked it I got an electric shock when I touched the bottom of the pump. I had raised it up 2" as it was running for 1-2 seconds then stop, start again etc. Our house is adjacent to the Sound and when the water table is up it runs constantly. This is a harsh environment so most likely a heavy duty pump is needed.
