Basement Finishing & Remodeling in Cortlandt Manor, 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 Cortlandt Manor 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 Cortlandt Manor

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 Cortlandt Manor 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



Work Requests From Cortlandt Manor, NY
Eton Ln in Cortlandt Manor
The basement has some repair needed of a support beam and the windows. Otherwise, it is a fairly small basement in good shape, with a stone foundation. There is some dampness, but no flooding. It might need a bunker door/window to be up to code for a living space. We also would like to install rough in plumbing for a utility sink and laundry, but no bathroom.
Sprout Brook Road in Cortlandt Manor
This property is situated not too far from a creek and I wanted to explore my options for having the basement waterproofed.
Carly Court in Cortlandt Manor
We are interested in finishing our basement.
TODDVILLE LANE in Cortlandt Manor
Our home was built in 1960 and the "finished" basement hasn't been updated since that time. We have demoed wood paneling from all walls and removed the drop ceiling tiles. It's pretty much a clean slate. Goal is to have a simple space with lots of storage, an update to the laundry space, and an addition of a small bathroom large enough for a standing stall shower. I'm sure there will need to be some electrical work as well.
Valley View Road in Cortlandt Manor
Cracks in basement wall, not wide, vertical. Buyer's inspector called them out and buyer wants us to have them repaired. Can send you pictures.
Adams Rush Rd in Cortlandt Manor
Positive side waterproofing due to gutters and land grade.

Wooden retaining wall is beginning to pull away from soil.
Stephen Lane in Cortlandt Manor
We need our backup battery generator for our sump pump repaired or replaced.
Habitat Lane in Cortlandt Manor
Cracking in the floor of the garage. Looks like there is moisture. I don't know if there are cracks on the walls as the garage has sheet-rock and insulation. Would like an expert to take a look at the inside cracks and check the outside perimeter of the house to ensure no other cracks exists. Then a quote to repair.
Inwood Lane West in Cortlandt Manor
We had some minor leaking in our basement in August of last year during Tropical Storm Irene. This was the first time that we had any leakage from storms. Then we had some additional minor leaking more recently after some thunderstorms. Our house in Cortlandt Manor, NY is 14 years old. We assume that this situation was caused by the heavy rains when the ground was saturated. We would like our basement to be inspected for potential cracks and other issues, and then determine what repairs or other actions may be necessary to prevent leakage in the future. I would like to schedule someone from your company to inspect our basement and make some recommendations. Thank you.
Inwood Lane West in Cortlandt Manor
We had some minor leaking in our basement during Tropical Storm Irene at the end of last month. Our house in Cortlandt Manor is 13 years old. This was the first time that we had any leakage from storms. We assume that this situation was caused by the heavy rains when the ground was saturated. We would like our basement to be inspected for potential cracks and other issues, and then determine what repairs or other actions may be necessary to prevent leakage in the future. I would like to schedule someone from your company to inspect our basement and make some recommendations. Thank you.

Would like to get an estimate for a sump pump in a crawlspace.
Rancho Drive East in Cortlandt Manor
I'd like to arrange a quote for waterproofing our basement. We've tried exterior drainage, but believe that an internal drainage system hooked up to our sump pump is the only way to solve our problem. Thank you.
