A homeowner in Stonington, CT expressed interest in upgrading his sump pump system. After experiencing issues with his past sump pump system, he reached out to Connecticut Basement Systems, scheduling a free in-home consultation with Sales Representative Bret Citrin.

Once Citrin arrived at the home, he expressed potential options for the homeowner. Ultimately, the homeowner decided to install our SuperSump Plus sump pump system and SaniDry Sedona dehumidifier. These two systems work in tandem to mitigate moisture, with the self-emptying SaniDry feeding moisture into the SuperSump Plus, where it is expelled at a safe distance from the house.

On the day of the install, Foreman Luis Alas and his team arrived, immediately getting to work removing the old sump pump. Following a quick install, the crawl space's waterproofing abilities were enhanced!

Job Stories From Stonington, CT
Crawl Space Upgrade - Stonington, CT

A homeowner in Stonington, CT expressed interest in upgrading his crawl space. Previously a damp space, the homeowner wanted to seal the space off from any additional moisture. Thus, the homeowner reached out to the experts at Connecticut Basement Systems for assistance.

Upon calling, the homeowner made contact with Sales Representative Bret Citrin. Citrin offered a free in-home consultation, arriving at the home shortly after to discuss the homeowner's options.

Ultimately, the homeowner decided to have a variety of systems installed, ranging from our CleanSpace vapor barrier to SaniDry Sedona dehumidifier. Voicing concern over the state of his antiquated sump pump system, Citrin suggested a SuperSump Plus sump pump system. Once approved, Foreman Luis Alas and his team arrived to begin the installation process. With a full front of waterproofing systems, the homeowner's crawl space is now protected against moisture for years to come!

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!

We want to convert our basement into an in-law apt. With two bedrooms, a bathroom , and a Kitchenette. We are new homeowners and it has been a dry summer so we don't know if there are water problems - but it does not appear that there are major issues with leaks.
Project Location: Stonington, CT
We live in a home built in 1840. The basement is very damp. Some of the floor appears to be dirt. There is a hole about 2-3feet in diameter that always has standing water. Looks like it once had a sump pump. It is frankly disgusting and we are unable to really use it for storage. The smell comes up through the door in the kitchen that leads to the basusable. I'm concerned about mold. What are our options for making the space SAFE and/ ousable.I?
Project Location: Stonington, CT
We have a 35 year old ranch home that about 6 years ago had a basement flood as result of a very heavy rain event. When the home was built there were concerns about the water table so curtain drains were put in but no sump hole. We never had a problem in that time but about a year before the flooding a home was built next to us in which tons of fill was hauled in to build a driveway over wetlands and many trees removed from that property. Since that time we have periodically had basement flooding with spring rains and have had to pump it out. We have had landscaping work done with downspouts rerouted away from the house in an attempt to resolve the issue but it seems to be getting worse. There now are noticeable cracks in the walls and floor of the basement with water most noticeably coming thru those but also seems to seep in everywhere. With the unusual winter driving rain storm a few weeks ago we had flooding again and pumping was very difficult due to the cold weather that followed freezing hoses. We had someone come and pump it out but some puddles remain. We realize that we need to do something about it and would like to have you take a look at it and give us an estimate of what it would entail.
