Basement Finishing & Remodeling in Chappaqua, 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 Chappaqua 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.

You will have peace of mind as we provide a 25-year written warranty against defects on our foundation products.

PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your Chappaqua home is both an eyesore and a safety hazard. It is also likely to get worse, but we can fix it for you.

Our experts use PolyLevel, a superior polyurethane foam. Small holes are drilled in the concrete, the foam is injected and the expanding foam lifts the concrete. The majority of contractors you will call use mudjacking instead of foam. Mudjacking is heavier, require larger holes in the concrete and does not last as long as PolyLevel. Call us today to learn more.

We Fix
  • Cracked Driveways
  • Uneven Patios
  • Sinking Sidewalks      

  • Uneven Concrete
  • Sunken Pool Decks
  • Highway & Commercial Issues

Job Stories From Chappaqua, NY
WaterGuard System in Chappaqua, NY

This Chappaqua basement had a water issue every time it rained. Water would seep through the floor which would cause the basement to have a musty odor and be an unpleasant environment. This became frustrating to the homeowner and he wanted to find a solution. He decided to call Connecticut Basement Systems since they are the experts in all things basementy!  

On the day of the appointment, Sales Representative Brad Glazer arrived at the home to assess the situation. He concluded that a WaterGuard system would be the perfect solution. Paired with a Triple Safe sump pump. Brad explained the benefits of each of the products to the homeowner. The WaterGuard system is a below the floor drainage system that collects water internally. The WaterGuard system then collects the water and channels it to the Triple Safe sump pump. From the sump pump, the water exits the basement through a discharge line. These are two great products that will ensure to keep your basement dry all year. The homeowner was impressed and wanted the system installed. 

On the day of production, Garfield Sanderson and his team installed the products professionally and efficiently. Once the project was completed, the homeowner was thrilled with the results and could not be happier with his dry, musty odor free basement!
