This homeowner in Columbia, CT noticed that their foundation was starting to bubble and cave in. Thankfully, they were in great hands once they called us at Connecticut Basement Systems. Sales Consultant Tim Kane was able to take a look at this foundation and provide an estimate for the homeowner. Once the date was set, our foreman, Sergio Alves, brought his team in to tackle this foundation!

 

They installed the PowerBrace Wall Repair System. This will stabilize the bowing walls, forcing them back into their original position. This crew will revisit the home in approximately 1-2 months to tighten and possibly push the wall in. Soon enough, this foundation will be as good as new!

Job Stories From Columbia, CT
The PowerBraceâ„¢ Wall Repair System Installation in Columbia, CT

A customer in Columbia, CT noticed their basement wall was out of place and starting to cave in. This caused them to worry as their foundation wasn't getting the support it needed. They quickly called us at Connecticut Basement Systems, where our appointment center promptly sent one of our Sales Consultants, Tim Kane, to the house. Tim saw the bowing basement wall and proposed installing our PowerBrace™ Wall Repair System. The PowerBrace™ is an adjustable steel I-beam system designed to force the bowed wall section back to its original position. He ensured the customer that our system would give their basement walls the proper foundation support.

 

Once the appointment was set, one of our Foremen, Sergio Alves, and his team came to solve the customer's problem. The team began by pouring a 21-ft concrete footing to install our system. Once the footing was set, the team attached four I-beam Power Braces to it. They informed the homeowner that they would need to return in approximately 1-2 months, after the concrete had fully cured, to tighten the braces and push in the wall.

 

These I-beams will look like new for decades to come due to their anti-corrosion zinc coating. Soon enough, the wall will be back to its original position, giving this home its full foundation support!

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!

Water in the basement
Project Location: Columbia, CT
Looking to renovate a space in our basement into a finished space. Concerns would be little leaking, and well pump in same room.
Project Location: Columbia, CT
Hello, My basement constantly floods. I'm always setting up pumps, dragging hoses out the window, and then having to monitor those pumps so they don't burn out. It is basically unusable space due to the constant water and associated mold. I recently pulled out walls so most of it is down to the concrete and open rafters. I'm nervous about what is above and below a small section that has a subfloor and ceiling, so I left those in place. I would like a completely waterproof solution and have it finished so I can use it for laundry/storage/work area/living space (tv/couch/etc.). Regards, Drew
