Beautiful Crawl Space Transformation in Old Lyme, CT

Mark K. was complaining about a damp smell in the basement and coming from the crawl space and they were also concerned with cold floors above the crawl space. He wanted a solution, and he wanted one fast, so he gave us a call at Connecticut Basement Systems, and we were happy to come and see how we could solve his problem!

Our System Design Specialist, Ferdinand Gojani, came out to survey the space, and assess what needed to be done. The first thing he suggested was a CleanSpace Radiant Vapor Barrier. This bright, white vapor barrier completely transforms a crawl space, while also working to reduce moisture and humidity within the crawl space. It also helps seal out cold drafts in the winter, and is suitable over walls and floors. We also installed a SaniDry dehumidifier, which is designed to provide many years of energy-efficient, trouble-free performance, even in tough crawl space conditions. SilverGlo rigid foam insulation was also installed. This rigid foam insulation shed water instead of soaking it up like cellulose and fiberglass insulation. The best part? It doesn't support mold EVER. 

This crawl space was transformed from dark to dazzling, and this family can now use the space for storage! Call us TODAY for your free, crawl space estimate!

Job Stories From Old Lyme, CT
Basement Waterproofing - Old Lyme, CT

A homeowner in Old Lyme, CT expressed concerns regarding her basement's ability to mitigate unwanted moisture. With an antiquated sump pump carrying the entire basement, she knew it was only a matter of time before a large sum of water overwhelmed the system. To mitigate her concerns, she reached out to the experts at Connecticut Basement Systems for assistance.

Upon calling, the homeowner made contact with Sales Representative Brian DiRisi. DiRisi listened attentively to the homeowner's concerns and expectations. Scoping out the property, DiRisi measured various sections, including a safe length for an exterior drainage line. With the home visit concluded, DiRisi provided the homeowner with a formalized proposal.

With the proposal accepted, Foreman Delfino Mones arrived with his team to begin the installation process. To increase the proximity of waterproofing coverage, our WaterGuard French drain system was installed along the perimeter. This system, tying into our TripleSafe sump pump system, features three levels of protection against basement water. To tie everything together, our CleanSpace vapor barrier was installed along the walls to prevent further moisture and give a clean, uniform appearance.

With the install complete, the homeowner looks forward to enjoying her clean, stress-free basement!

TrenchDrain installation in Old Lyme, CT

The basement of this Old Lyme, CT home had a hatchway, with stairs leading into the basement from the outside. Water was able to enter the basement through the crack under the door. They needed this to stop, so they gave us at Connecticut Basement Systems a call, and we were happy to come out and help!

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.

Between 2005 and 2023 there were no incidents reported of water in my basement. Since 2024 there have been 2 incidents of water flooding the basement. It is entering in the seem between the basement floor and the wall. It appears to be ground water. The water table is high and there is a lot of flooding in the area; however, there has been a lot of flooding in the past and this has never happened before. Something has changed?
