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.

We have some very small leaks when it rains. in one small area. But in general our house is founded on bedrock and a special system of french drain type areas were set up to move the water under the house. We would like to discuss the maintenance of this initial design. The previous homeowners were not as proactive

I have water intruding into the basement of my detached garage. I'd like a price quote from you.
Project Location: Cortlandt Manor, NY
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.
Project Location: Cortlandt Manor, NY
This property is situated not too far from a creek and I wanted to explore my options for having the basement waterproofed.
Project Location: Cortlandt Manor, NY
We are interested in finishing our basement.
Project Location: Cortlandt Manor, NY
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.

Project Location: Cortlandt Manor, NY
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.
