Basement Finishing & Remodeling in Katonah, 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 Katonah 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 Katonah

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

Vicinity of Meadow Lane in Katonah
We have a new house built on a 50 year old cinderblock foundation. The basement flooded 2 or 3 times over 5 years ago after a very snowy winter / rainy spring. It has not flooded since. We are thinking about finishing the basement and would like to discuss some solutions that would prevent floods in the future. Thanks

Vicinity of Sunderland Lane in Katonah
Water seepage in my un finsihed basement. pourd concrete walls. leakisn in several spots.
Vicinity of Cedar Rd in Katonah
Just moved into an old house. Confident the foundation is essentially fine, but there are issues around part of the perimeter of the house. There is a stone wall on part of the back of the house, which is on a hill. Concerned about soil erosion in this area leading to water leakage on the lower cedar panels of house. Also there is some indication of water leakage inside the house from the stone wall onto the hardwood floor. Concerned as well that any cracks may lead to rodents or insect infestation.
