Basement Finishing & Remodeling in Larchmont, 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 Larchmont 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 Larchmont

PolyLevel™ Concrete Leveling & Lifting

The sunken and cracked concrete around your Larchmont 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 Larchmont, NY
Chatsworth Ave in Larchmont
Cracks in walls, rain leaking in, poorly sealed exterior doors - musty basement.
Palmer Avenue in Larchmont
Looking for estimate on interior perimeter drainage systems. We've had seepage in our basement cinder block walls in the spring during the snow melt every year. Only part of our house has a basement; the other parts have crawlspace only but even the walls along those sides are leaking in the Spring. Sump pump is working ok but basement still has a little water accumulation as the floor doesn't slope down toward the sump pit.
Concird Ave in Larchmont
The basement is mostly dry. Looking to have it finished off as a play room. Thanks, Matt Additional information: What prompted you to contact us today?: Internet Search

Beechtree Drive in Larchmont
Helena Ave in Larchmont wife and I just bought a 1920 brick colonial. The basement does not get terribly wet...a bit of water seeps in. The humidity levels is high. We're thinking an interior French drain and humidity control system would work well. There is an existing sump well and pump to tie into. We'd like to have this space a a safe storage/laundry area for now, with the possibility of converting into living space in the future. Please let me know next steps. Thanks, Michael

Chestnut Avenue in Larchmont
I consistently have water in my basement and would like to correct this problem. In addition to correcting the water problem I would like to 'finish" the basement in a very minimalist way; putting in a ceiling, adding storage and shelving, painting walls and floors.
Bishop Place in Larchmont
We have a wet crawl space, two sump pumps keep water moving out but seepage seems to have gotten worse.
