It is very important to get your Connecticut Basement System sump pump maintained every year. Dirt and sediment build-up in a sump pump liner can cause pump failure which can lead to flooding. Your pump is an electromechanical device that needs to be annually maintained. 

The before and after photo shows a sump pump basin filled with dirt and sediment build-up. After Alberto Vasquez maintained the system, the sump pump basin was transformed to a clean and efficient system. Now, this homeowner’s system will remain high-performing which will keep the basement dry all year long!

Before, this Rye Brook crawl space was dark and damp which caused for an unhealthy environment. The homeowner wanted to transform the environment to a dry and healthier space. After doing her research to find the perfect company to help find her a solution, she decided to go with the experts at Connecticut Basement Systems.  

The solution for this crawl space was to install CleanSpace liner, a WaterGuard system and a SaniDry Sedona. The WaterGuard system will keep the crawl space dry by channeling the water internally to the sump pump. The CleanSpace liner that is applied to the walls and floors of the area prevents air and moisture from entering the space. Lastly, a SaniDry Sedona Dehumidifier was installed to keep humidity low which will make the air healthier by getting rid of moisture and preventing mold from growing. Now, this crawl space is transformed and the homeowner is thrilled with the results!

Basement Finishing & Remodeling in Port Chester, NY

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Port Chester contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

We are looking at a property we would like to purchase. We had it inspected and results show there was a water issue in the basement. The owners apparently had it water proofed but our inspector's results showed it was done incorrectly. We would like an estimate for the costs to have the basement waterproofed, possibly from the outside and/or inside to help us determine if we want to proceed with purchasing. Thank you.
