Job Stories From Columbia, CT
Everlast Wall Restoration in Columbia, CT

In a Columbia, CT house, a family was having trouble with water ruining some of their basement walls. Some walls had been so badly damaged from the water that they turned black with mold covering it. Once the family decided to take action to replace these walls, they called us in order to rid their family space or harmful and pungent mold growths.

Once it was time for the appointment, our salesman suggested that Everlast walls would be the perfect replacement for having a beautiful new look in the basement, as well as keeping mold from growing through the walls. The salesman described to the homeowners that the inorganic fibers that make up our Everlast walls makes it so mold cannot grow or live on the walls, and that the walls are also moisture and water resistant.

For this family's problem, we had the perfect solution, and they thought the same thing. Once a price was agreed upon, our installation crew got to work removing the old and moldy walls from the Columbia basement, and installed the new and beautiful Everlast wall pannels. This completely changed this basement from a water damage AND an aesthetic perspective. The family was thrilled with their new basement walls and were grateful for our solutions and strive to help families such as them.

Waterproofing Transformation in Columbia, CT

These homeowners in Columbia, CT had an ongoing water problem in their basement. They had water coming in through the walls, and from the space where it met the floor. They gave us a call at Connecticut Basement Systems to come check out the problem, and we were happy to offer them a solution! Our expert foreman Kryz Wilk came in, and got the job done! He installed our patented WaterGuard drainage system, to make sure all the water coming in was collected. To collect the water from the drain system, our premier sump pump, The SuperSump, was installed. The pump is capable of pumping out 2,200 gallons of water per HOUR, so the family never has to worry about water flooding their home. This family can feel comfort in knowing their basement will be dry from now on!
