Before, this Old Saybrook basement was filled with moisture that was affecting the walls and floors of the area. The bottom of the walls had to be removed as it was too damaged by the moisture and they did not want to risk a problem of mold. The floors were too unpleasant and uncomfortable for anyone to enjoy. The homeowners decided that an upgrade was needed and trusted the experts at Connecticut Basement Systems. 

The solution for this basement was to install EverLast wall restoration and ThermalDry flooring. The wall restoration is designed to prevent any damage caused by moisture including the growth of mold. They are also strong and durable while looking great as an accent to any basement. Light Pecan ThermalDry flooring was installed with benefits including a thermal break from the cold slab allowing the surface to be up to 10 degrees warmer than the concrete foundation and a grid design to stop water vapor preventing mold and odor. The transformation was incredible and the homeowners were happy with the results.

Job Stories From Old Saybrook, CT
PolyLevel Injection in Old Saybrook, CT

These Old Saybrook homeowners were extremely concerned with the uneven cement and cracks that were developing along their pool. They did not want these tripping hazard to ruin their summer fun, so they decided to give Connecticut Basement Systems a call to find a permanent solution. 

Shortly after giving us a call, an appointment was set for our System Design Specialist, Matt Kraus, to evaluate the situation. He concluded that a PolyLevel injection to the problem areas would be the best option to level the sinking cement. PolyLevel is affordable, waterproof, and quickly curing, which makes it the perfect solution for this Old Saybrook poolside. Within hours after the injection, the poolside cement was leveled and ready for a fun, safe summer.

Now these homeowners are worry-free about their sinking cement and can be reassured that their poolside will be safe for all to enjoy.

Inspection and installation of vapor barrier under summer cottage
Vicinity of Buckingham Ave. in Old Saybrook
We have a crawl space which we believe is where the strong odor is coming from into our kitchen, bathroom and living area. It has been present for the last few years but typically goes away in the summer. It is now year round. From our research as we are no experts, we are guessing that the dirt which as come into the crawl space and is now in two corners of the concrete floor is emitting the order. We are thinking if we could get the crawl space and house tested (VOC test?) and potentially remove the dirt, figure out a ventilation strategy and potentially figure out how to insulate and/or create a barrier between the crawl space and house. If you are working during this pandemic, we need help ASAP as we are now living here full time.

Vicinity of Maynard Circle in Old Saybrook
We have had a quote by you 4 years ago. I cannot remember the name of the system expert; he lived in Colchester- nice guy. We decided to hold off at that time because we were considering filling in our basement. However, we have decided we could use the space for a play area. We would like to " waterproof" our basement by upgrading our existing subpumps. We also want to make a playroom in the basement. Also possibly new basement windows.
