In cold climates, winter winds will beat against your basement windows, rapidly pulling heat away from your home. The cold wind can lead to serious energy losses, especially if you have single-paned steel windows. By installing a basement window well with a clear plastic cover, you can hold back those cold winds, protecting your windows and saving you energy.

Job Stories From New Canaan, CT
Waterproofing in New Canaan, CT


A homeowner had contacted us regarding a need for waterproofing services in his basement. Without a basement with proper waterproofing, many issues can occur including water damage to the floor and walls, flooding, and the growth of mold. Oftentimes a damp basement causes a musty odor as well as the potential growth of asbestos and other molds which then can become a health issue within one’s own home. Once we heard that assistance was needed, we sent out our expert, Sean Colson, to assess the basement. 


While we have many solutions that are used to completely waterproof basements, one that was crucial in the process of waterproofing the homeowner’s basement was the installation of an UltraSump III. This is a sump pump that was installed to remove water that had accumulated in a sump basin under the homeowner's basement floor and to make sure water levels never got too high so now leaks could occur. Following the sump pump, our crew then implemented a whole new basement flooring. They put down over 1,400 tiles of ThermalDry Floor Matting which created a whole new and improved basement floor. The ThermalDry matts are interlocking waterproof tiles that create a warmer surface while also forming a water barrier above the basement floor. Without this flooring, any water vapors that pass beneath the concrete floor would be absorbed by any carpeting or padding which would cause unwanted odors.


The final step our experts took in fully waterproofing the homeowner’s basement was adding a SaniDry Sedona dehumidifier. By adding this, damp and musty odors will be eliminated by drying and filtering the air. In addition to filtering air, this machine will also filter mold spores, dust mite droppings, dust and other unwanted particles. With automatic drainage and humidity settings, the homeowner will not have to worry about tending to his new humidifier. In addition to waterproofing, the basement was also in need of a repaired crawlspace, which was easily fixed by the addition of drainage matting and wall caps. The matting is put over concrete to allow for proper draining of the crawlspace while wall caps are put over concrete walls to disallow moisture going from the concrete into the crawlspace. With the addition of all these solutions, this homeowner will not have to continue to worry about water issues in his basement or crawlspace.

Project Location: New Canaan, CT
We are on the first floor of our condo building and the basement is a crawl space area. There is a constant flow of water (sump pump has to run constantly even in sunny weather) and there is alot of humidity and even sitting water in the basement area. I can only assume there is mold. There is also always sitting water on our lawn where the water should be draining, through a pipe, out to a water drain.
