Building Finished Basements that Last

1. You want to have a comfortable, beautiful finished basement, BUT you want it to last!

2. Most contracting companies use standard “above-grade” materials which is a recipe for disaster. These materials end up with mold and mildew and you have to tear out the whole basement and start over.

3. Total Basement Finishing contractors eliminate these problems by only using completely waterproof, inorganic & mold-resistant materials that are designed specifically for basements. You will have the basement you've wanted and it will last long as your house.

Patented Basement Materials

Once we’ve completed your basement remodeling project, we guarantee you’ll be as pleased and confident in our craftsmanship and sturdy materials as we are! 

Our Products Include:

  • Waterproof, Washable, Insulated Walls
  • Mold-Resistant, No-Sag suspended Ceilings
  • Full Basement Bathrooms
  • Variable, Energy-efficient Basement Lighting
  • French, Bifold & six-paneled steel Doors
  • Basement Staircases
  • Energy-efficient, Double-paned Windows
  • Carpet, Tile & Faux Wood Flooring

We use and install only top-quality, patented products and materials, including basement tiles, walls, and floors, as well as basement windows and energy-efficient dehumidifiers. Any and all work completed by our basement finishing contractors comes with a 50-year mold-and-moisture warranty to ensure lasting comfort in your home. We design, build and exclusively install our basement products. 

The materials and products we use are not only strong and durable, but also eco-friendly! Our basement windows, for example, are properly insulated to eliminate drafts and wasted energy. And while our SaniDry Air System can remove over 90 pints of water from you basement each day, it uses just 6.8 amps of energy daily.

    Happy New Year! Meera and I have spent a significant amount of time talking over the basement. . You and the rest of the company seem very easy to work with and your quotes were significantly less than what we had received otherwise, so should we revisit the project in the future as our kids get older, you would be our first call.
