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.

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 Ossining 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

Birchbrook Road in Ossining
I experienced a flooded basement for the second time since purchasing my home in June of 2007. There is a drain at the foot of the stairs to my sub grade door to the basement that overflows when it rains really hard as it did this past weekend. I need to find a solution to this problem before I even consider re-finishing the basement. I used your company before to seal off the crawl space under one of the rooms in my house (it was an added room to the original construction. At this point I am looking for an estimate so I can start budgeting for this much needed repair.
