Job Stories From Deep River, CT
PowerBrace System in Deep River, CT

Before we arrived at this Deep River home, the walls in the basement were bowing which caused great concern for the homeowners. The homeowners have a right to be alarmed, outside pressure from soil and water can actually cause foundation walls to collapse! They knew they would need to find a solution, so they decided to give Connecticut Basement Systems a call.

On the day of the appointment, our Sales Representative Matt Kraus, arrived at the home to evaluate the situation. Once he saw the bowing walls, he knew that the homeowners would need to have a PowerBrace System installed to correct the walls into the right position. He thoroughly explained the products to the homeowners and they agreed that this would be best for their home. 

On the day of installation, Victor Alves and his production crew installed the PowerBrace System professionally and efficiently. The PowerBrace System are steel i-beams that will stabilize the wall in its current position without any further alteration. An added bonus about this system is that the beams can be tightened over time to straighten out the walls. 

With this system installed, the homeowners now have a peace of mind about their bowing walls. They were extremely happy with the products and results! 

Have foundation issues in your home? Bowing walls? We can help! Give Connecticut Basement Systems a call to schedule your FREE home evaluation! 1-855-200-7133

Project Location: Deep River, CT
I have a four-foot crawlspace under the main part of my house, which was built in 1974. I have cleaned out the junk, except for a few items, so the only things there are the water heater and the pressure tank. (I have a well.) There is at least one leak in the walls and one broken window. I had it insulated 3 yrs ago, but a lot of that insulation is falling down. Basically, I would like help with repairing the walls, window,and insulation - and possibly the bulkhead door - and probably waterproofing the walls, although that might depend on price. Does this sound like something you can help me with?
