The homeowners in this Cos Cob, CT home had a continuing water problem in their basement. They had water coming in through the walls and forming mold. The homeowners were unsure of what they should do when they contacted Connecticut Basement Systems for an evaluation. We sent out our basement waterproofing expert Ralph to solve the problem. Ralph identified water seeping in through the walls and recommended installation of our CleanSpace vapor barrier. Our wall vapor is a 100% waterproof material that prevents any moisture from coming in through the walls. Any moisture that comes in behind the vapor barrier is taken care of by the DryTrak baseboard drain system. This drainage system will carry any intrusive water out of the basement and, as opposed to traditional french drain systems, there is no need to jackhammer. 

The homeowner has the peace of mind that any leaks or water  that tries to make its way into the home will be transported out!

This Cos Cob, CT home was suffering from water flooding into it's basement, and unwanted moisture causing both mold and damage to their basement walls. They decided to give us a call at Connecticut Basement Systems to solve the problem!

Our expert foreman, Kryz Wilk, and his team worked diligently to make this basement safer and comfortable. First, they installed a SaniDry to rid of any moisture problems this basement was having. The SaniDry creates clean, dry air, removes risk of mold growt, and never needs to be emptied. We then installed our SuperSump system in order to properly drain the basement of any unwanted water. We also installed our TrenchDrain basement entrance drainage system, so that water flooding in from the stairs would be completely eradicated. 

At the end of the day, this family can live peacefully knowing the moisture and water that plagued their basement in the past would no longer be an issue. Give us a call to get your FREE quote today!

When this Cos Cob family called us, they complained of water leaking into their basement through the stairs, so much so that it was beginning to cause permanent damage in their home. They wanted a rapid solution, so they called us at Connecticut Basement Systems to come take a look, and see what we could do! 

We called on our System Design Specialist, Vincent Orsini, to come and take a look at the problem. He was quick to find a solution to the challenges they were facing, and brought Kryz Wilk, and his team, to get the job done! We first installed a TrenchDrain around the perimeter of the basement. This drainage system leads to a TripleSafe Sump Pump, which has two different pumps, AND a backup battery, so you never have to worry about your basement flooding during a serious storm. We also went ahead and installed a Lawnscape and Iceguard, which prevent any back ups in the sump pump system. 

Now, this family have a full proof water removal system, and can feel safe in their home. Call us for your FREE estimate today!

PLEASE NOTE: There is water in the after photo to the TrenchDrain installation service!

The house is on a hill with water leaking through the cinder blocks into the garage during heavy rains. This is next to a narrow walkway between the house and the rocks that all water flows down.
