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

Foundation problems destroy your Larchmont home’s value and can be dangerous. Our in-house team of structural and geo-technical engineers are here to help. We design and install the right solution and usually have the project finished in less than a week. You will have peace of mind as we provide a 25-year written warranty against defects on our foundation products.
