Before After
EverLast Basement Windows in Danbury, CT EverLast Basement Windows in Danbury, CT

Before, this Danbury, CT home had basement windows that caused a draft, were filled with debris and just unappealing. The homeowner wanted efficient windows that also had an appealing look for her Cape Cod home. She knew the experts at Connecticut Basement Systems would be able to help.

Our Sales Representative, Doug, was able to show the homeowner the features of our EverLast window inserts and SunHouse window well. These basement windows will not rust or rot because they’re built with reinforced vinyl frames. Plus, they feature a double-pane, insulated glass to prevent major heat loss. The SunHouse window wells are durable, prevents weeds from growing with its solid base, and its light color and curved form directs sunlight into the basement!  The homeowner loved these solutions and with these simple upgrades, she was thrilled with her efficient and beautiful basement windows and window wells!

Job Stories From Danbury, CT
Waterproofing in Danbury, CT

The Toll Brothers Company in Danbury, CT was experiencing a wet basement. Luckily, the owner knew of our waterproofing Specialist, Rick Raucci and contacted him for a free no obligation estimate. He arrived at the property to assess the problem and determine what would be the best solution to waterproof their basement. He decided that it would be best to install our WaterGuard drainage piping system along with the WaterGuard Port. 

 

With a prepared plan Jose Blees and his production team got to work. They installed the WaterGuard system which is installed inside the perimeter of the basement to prevent wall and floor seepage before it reaches the basement floor. They also installed the WaterGuard Port which supports the WaterGuard system and is easy to use for inspection. 



The Toll Brothers were satisfied with the work completed and with now their dry basement. They were so pleased that they continue to use CT Basement Systems for various other jobs.

 

WaterGuard System in Danbury, CT

These Danbury homeowners were tired of experiencing a wet basement every time it rained. They were seeking a solution to keep their basement dry all year long. After researching for the best solution for their basement, they decided to give Connecticut Basement Systems a call to set an appointment for a free home evaluation estimation.

Our System Design Specialist, Leonard Fletcher, arrived at the home and evaluated the basement. He concluded that the WaterGuard system would give a solution these homeowners were looking for. Once the proposal was approved, Sid Aviz, and his production team installed the system professionally and efficiently. 

The WaterGuard is a drainage channel that leads water coming into the basement to the sump pump, where it is driven out of the home. Basement waterproofing is our specialty, so we were confident that this system would keep this Danbury basement dry all year long. Now, these homeowners are happy with their waterproof basement! 

Waterproofing and Refinishing Your Danbury, CT Basement

Tom and Maria C. had been thinking about waterproofing and finishing their basement for some time. When they were finally ready to take that step to improve and expand the living space in their home, they reached out to Connecticut Basement Systems. Waterproofing specialist Brad Glazer sat down with the couple to design a plan to keep water out and totally transform their unfinished basement.

Sid Avis and his crew arrived at the Danbury home soon after, installing a Waterguard interior drainage system, an exterior discharge line, a TripleSafe sump pump, and an IceGuard system. Once their basement was completely waterproofed, the crew was able to quickly put in a brand new ceiling, doors, walls, and the ThermalDry flooring.

After the work was complete, Tom and Maria had a beautiful new space for family and friends to hang out in. They also had a lifetime warranty, giving them peace of mind that Connecticut Basement Systems will be there for them in the future if ever needed.

Repair Cracks Before Selling Your Home in Danbury, CT

Ralph N. was getting ready to sell his home in Danbury when he noticed a sizeable crack in the basement wall. Knowing that a new homeowner doesn’t want walk into a set of problems, he contacted Connecticut Basement Systems online. Two days later, Ron Marra was at Ralph’s home and knew just how to solve the issue before it worsened.

Ron brought in foreman Justin Vizzard, who used the FlexiSpan Foundation Wall Crack Repair System to seal it up in a few short hours. If Ralph had decided to leave it untreated, the new homeowner could have encountered everything from unwanted water seeping in to the wall breaking down even further over time. He was very happy with the work done by Connecticut Basement Systems and could rest assured he was turning over the house in good, safe

BrightWall Waterproofs and Brightens Your Danbury, CT Basement

No one knows more about the quality that needs to go into a home improvement project than a contractor himself, which is why when Bill S. encountered water in his basement, he knew the company to call was Connecticut Basement Systems. Waterproofing specialist Glenn Kerpchar visited Bill at his Danbury home to look at the best way to keep his basement dry.

With Glenn’s recommendations, Sid Avis and his crew installed a Waterguard interior drainage system, a SuperSump sump pump and an IceGuard system, as well as a Lawnscape outlet in the yard. They also put up BrightWall basement wall paneling, since coating it with paint or sealers is not a solution that will last. It not only brightened up the room, but now drains water and stops water vapor from sneaking in. On top of the fact that Bill’s basement will no longer take in water, the overall appearance of the room itself was significantly improved.
