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 only high-quality materials when remodeling basements in New Hampshire. Our ThermalDry flooring, for example, will not warp or delaminate like wooden floors, and our mineral fiber basement ceiling tiles come with a 30-year warranty against mold and mildew. Simply put: we take care of our customers and guarantee that they receive the best service, materials, and craftsmanship around!

A professionally remodeled basement can do all of this and more! Transforming a musty basement into a safe and usable living space will drastically increase the resale value of your home. A finished basement with eco-friendly additions, such as our EverLast Basement Windows and Energy Star SaniDry dehumidifier, can decrease your home's energy usage and lower your monthly electric bill!
