Waterproof & Mold Resistant Products 
for Remodeling Your Basement

You want a beautiful, finished basement; BUT you also want it to last. New Hampshire experiences an average of 17 floods each year, which result in basement water damage in homes throughout the state. Most companies use traditional building materials like wood, fiberglass or drywall that are vulnerable to water damage and mold growth.

Don’t spend thousands of dollars on your basement project only to have to redo it after water damage! Choose from our beautiful, waterproof materials for a perfect basement that will last.

Mold & Water Damage

Water finds it way into your home’s foundation, whether this be in a flash flood or moisture seeping through the concrete over time. The real problem occurs when the water or moisture comes in contact with organic materials like wood, plywood, carpet, tiles, fiberglass, and even products like “mold-resistant” drywall. Water in the basement means mold and rot will begin to grow and the drywall may need to be restored and repaired, but more likely, your beautiful Portsmouth basement will need to be completely gutted.

Advantages of our Basement Materials

To prevent water damage to your basement, we install a water drainage system and then finish your basement using materials that are waterproof and truly mold resistant. Our materials look just like wood and tile but are not organic and not susceptible to mold. Our materials are also easily washable. You don’t need to search for studs in order to hang items on the wall, as our panels support up to 300 lbs! Each of the panels is built with an unbroken sheet of insulation inside and the floor panels have raised pegs keeping them off the concrete. This completely insulates your basement.
