Basement Finishing & Remodeling in Pelham, 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 Pelham 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.

Structural & Foundation Repair in Pelham

Job Stories From Pelham, NY
WaterGuard System and EverLast Windows in Pelham Manor, NY

This Pelham Manor home had a basement that needed to be waterproofed. It was becoming a nuisance to the homeowner to deal with a wet basement and she wanted to find a permanent solution. After doing her research on the internet, she decided to trust the all things basement experts at Connecticut Basement Systems to provide a solution. She called and scheduled her free, no-obligation estimate.

On the day of the appointment, Sales Representative Keith Rongey arrived at the home to inspect the basement. The solution for the wet basement was to install a WaterGuard System. This system is installed around the perimeter of the basement below the floor. It will collect the water internally and direct the water to the sump pump, which will discharge it away from the home. Our superior TripleSafe sump pump was also recommended which has three pumps to handle a great deal of water. The combination of these products will ensure a waterproof basement. The homeowner was also interested in upgrading her windows as they were old, rusty and allowing a lot of air to flow through. Keith recommended our EverLast windows which are reinforced vinyl frames that will not rust or rot and also have double-pane glass which will prevent heat loss. Not to mention they will allow more natural light to shine through the basement. After reviewing all the products with Keith, the homeowner decided that the WaterGuard system and EverLast windows would be the perfect solution for her basement and wanted to move forward with the project.

On the day of installation, Foreman Krzys Wilk and his team installed the WaterGaurd system and EverLast windows professionally and efficiently. Once all the products were installed the basement was transformed to a dry and brighter area. The homeowner was impressed with the results and was glad he trusted the experts at Connecticut Basement Systems.

We had water in our basement, in part because the exterior door to the basement broke open. We would like to install a steel door and waterproof the basement.
