Job Stories From New London County, CT
Waterproofing in New London CT

Wet spots in a basement are always a sign of concern and, when Susie D. found them in her basement, she knew that towels would help only so much.  Susie began researching companies and found Connecticut Basement Systems soon after.  She then met with waterproofing specialist Michael Lane, who had a solution to her water spot problem.

With Michael’s guidance, Luis and his crew came in and installed a Trench Drain and WaterGuard combo to ensure the current water would drain effectively out of her basement.  A SuperSump sump pump was also installed to ensure future flooding would be a problem of the past.  Finally a SaniDry Dehumidfier was installed to eliminate all future threat of excess moisture in the basement.

With Susie’s basement taken care of, Susie knows that the experts at Basement Systems know what they are doing and will hopefully continue to use their expertise for any of her future house problems!

Insulation and Waterproofing Installation in Mystic, CT

The old insulation and waterproofing methods in this Mystic, CT family's home was beginning to take a toll on their home. The house's original rim joist insulation was old, and costing them quite a bit on their energy bills. The rim joist is an area often overlooked when it comes to home insulation, and it is also a huge source of energy loss. On top of that, their old sump pump and waterproofing system just wasn't running like it used to. They gave us a call at Connecticut Basement to help fix the problem, and we were more than happy to come and take a look!

Once we diagnosed this houses problem with our system design specialist, we hopped right to work! We first removed all of the home's old insulation, and went ahead and installed our own Rim Joist Insulation. To do this, we used a closed cell spray foam. Closed cell foam cures dense and hard and is heavier than open cell foam. It forms an effective barrier against both moisture and air, making it hard for cold air from the outside to sneak in. 

Secondly, we went ahead and waterproofed the basement with our TripleSafe Sump Pump System! For normal functioning, the TripleSafe™ has a powerful, cast-iron Zoeller® ⅓ horsepower sump pump set at the lowest level. For heavy volumes of water or in case of primary pump failure, a second, more powerful Zoeller® ½ hp pump set a bit higher in the liner will take over. In case of a power outage, our UltraSump® battery backup sump pump, set at the highest level, will pump 11,500 gallons or more on a fully charged battery!

We left this family feeling confident that their home was now properly waterproofed and insulated! Call us today for your FREE quote!


Waterproofing Job in Ledyard, CT

This family in Ledyard, CT was looking for a full proof solution when it came to waterproofing their basement, and when they called Connecticut Basements for help, we were happy to do the job! 

After our System Design Specialist came in, and figured out what was best for the family's space, we called on our expert foreman to take on the job at hand. We first went ahead and installed our TripleSafe Sump Pump. This three pump system works together, and separately, to ensure that any water getting into the space will have no effect on their home.  If there is too much water for the first pump to handle then the second pump works at the same time from another discharge line. We also installed a WaterGuard around the perimeter of the basement.

TrenchDrain installation in Old Lyme, CT

To prevent this, our team installed a trench drain at the end of the stairs. This open grated drain collects water into the perimeter drainage system, preventing it from entering the basement. Both parts are made from heavy-duty reinforced plastic, so you’ll never need to worry about breakage, moisture damage, corrosion, or maintenance.  The homeowners now have a dry basement to enjoy, and we were happy that we could offer a solution to their problem.

WaterGuard in Stonington, CT

Before we arrived at this Stonington basement, it had water everywhere, making it unappealing and unusable to the homeowner. The homeowner wanted a solution to ensure a waterproofed basement so he could utilize the space. The homeowner did his research and decided to give Connecticut Basement Systems a call for a free estimate! 

Once the homeowner set an appointment, our System Design Specialist, Taz Peterson, arrived the day of the appointment. He concluded that in order to keep the basement dry at all times, a WaterGuard System paired with a SuperSump Pump would fulfill his needs. The homeowner agreed and understood everything that Taz had to say and wanted the systems installed in his basement. With no time to waste, Josh Gomes and his production team quickly went to work.

They installed the WaterGuard system by excavating the perimeter of the basement floors and placing the system underground. Then, they backfilled it with gravel and paved it back up. With the WaterGuard in placed, the SuperSump Pump was placed and installed in order to drain the water caught by the WaterGuard away from the home. The water is pushed through a discharge line and the water is released through a LawnScape.  

With the combination of the 2 products, the basement is staying dry and beautiful all year long and the homeowner is extremely happy!

SaniDry Sedona and Spray Foam in Uncasville, CT

This Uncasville, CT homeowner noticed that he had uneven temperatures throughout his home and had a lot of moisture in his basement . He wanted his home to be properly insulated and energy efficient. With this goal in mind, the homeowner visited the CT Basement Systems and Dr. Energy Saver of CT booth at the Southeastern Spring Home Show and talked to a promoter where he scheduled his appointment for a free estimate.

On the day of the appointment, Sales Representative Don Godbout arrived at the home to assess the situation. He went down to the basement first to inspect the basement. A lot of moisture in a basement is common problem and Don recommended installing a SaniDry Sedona Dehumidifier, which will keep the humidity in the air below 55%.
