Basement Finishing & Remodeling in Valhalla, 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 Valhalla 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 Valhalla

Foundation problems destroy your Valhalla 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.

Vertical hairline crack with water seepage in poured foundation. House is 2 years old.
Project Location: Valhalla, NY
I own a house that looks like it had a large addition put on in the 1980s. There is about an 1/8 inch crack formed between the old and new foundation. Interested in repair options. There is no water problem, just more concerned about esthetics and further settling, and what solutions are available.
