Water used to seep through the wall-floor joint of this Avon, CT garage every time it rained. To fix this, we installed out WaterGuard perimeter drain. The WaterGuard System is an award-winning, patented below-floor drain that rests in a bed of drainage stone on top of the foundation footing. By installing the drain at this point, it's kept out of the "mud zone", the point where clogged drains are common. The unique shape and large drain openings of WaterGuard also aid in prevent clogs in the system. With the WaterGuard installed, the owners have a dry, maintainence free garage!

Before, this Avon home was uninviting and cold where the homeowner could not enjoy this part of her home. The homeowener wanted to utilize her basement to its fullest potential and she knew finishing the basement would do just that. After doing her research and seeing our advertisement, she decided to trust the experts at Total Basement Finishing, a division of CT Basement Systems.

After completing the project, the basement was transformed into a beautiful and functional space. As seen in the after photo, the walls and ceiling were finished. We installed our EverLast wall panels. The benefits to these panels are that they are strong, durable and waterproof! They also look great in any basement. We also installed our ceiling tiles to make the basement completely finished. The transformation is incredible and the homeowner can now enjoy a bright and finished basement!

Before, this Avon, CT basement had an open space where the stairs connected to the Bilco door. Not only was this an eyesore, but it would let in an uncomfortable draft, welcome critters to the basement, and allow water seepage to the space. The homeowner wanted a dry, pleasant basement in order to sell his home. 

The solution we provided was to install a full perimeter WaterGuard system paired with TrenchDrains and a TripleSafe sump pump. In addition, our Total Basement Finishing door was installed. A warrantied door will help prevent the uncomfortable drafts, water from entering the space and deter critters, too! With this dry and pleasant basement, the homeowner was able to sell his home within two months.

Project Location: Avon, CT
We think we may have water seeping into the basement through a foundation crack?? We have damp walls and some wet carpet in the finished area of our basement. After removing a piece of drywall, it looks there could mold along the base of the wall/insulation and there is definitely moisture in the wall/insulation. There are no pipes in that area and it seems like seepage vs, dripping or flooding but we can't really telll and would like to turn it over to professionals to evaluate (especially with the strong possibility of mold).

I have one small leak in my basement. I am guessing it may be from a crack in the foundation. It only leaks when it rains really hard. I have ripped up the carpeting to identify where it is coming from.
