Basement Finishing & Remodeling in Ossining, 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 Ossining 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 Ossining

We just moved into our house a few weeks ago after completing some renovations. The house was built in 1987 and we had noticed a sag in the floors and some jagged cracks in the corners of some door frames. We had a structural engineer assess during our inspection and was told the house settled and appeared to be fine now. A few weeks ago, we found water in the basement after a heavy storm and the cracks we cosmetically repaired have since reappeared in the last month. I am very concerned there is a much bigger issue and am hoping you can come for an estimate and assessment. Thank you for your help!!
