EverLast Finished Basement Walls

EverLast Basement Walls

Our EverLast basement wall system is perfect for finishing your basement. They are finished on both sides so they look great from every angle, and have a high-density foam insulation rated at an R-13 insulation value. They’re fiberglass free and made of inorganic materials so no mold will grow on them. Their solid construction allows you to hang heavy objects from them such as a flat screen television. EverLast basement wall panels are installed without the need for wood or metal framing or studs.

ThermalDry Floor Tile

ThermalDry and MillCreek
Basement Floors

ThermalDry carpeted and tiled basement flooring is the answer to your basement floor needs. They are inorganic so they won’t support mold growth like wood does, and they come in a 12-inch square modular tile formation that locks tightly and easily. You can easily replace the squares individually by pulling them out then snapping them back in. Our MillCreek flooring is designed to look like hardwood but is made completely of inorganic materials. It comes in three wood colors and will give your basement a luxurious feel.

Linen and Prestige Basement Ceiling Tiles

The Total Basement Finishing ceiling tiles are specially made for the unique conditions of a finished basement. Created out of mineral fiber, our 2x2-foot x5/8-inch basement ceiling tiles are mold resistant and have a 30-year warranty against mold and mildew. The tiles come in two styles: Linen, which adds a bright and sophisticated look to your basement, and Prestige, which are textured to hide marks and dings to make it perfect for a children’s playroom or game room.

The air-tight EverLast basement windows keep bugs rodents and other outdoor elements out of your basement and look great! They are also energy efficient and made of double thermopane glass. EverLast windows are made from vinyl so they will never rot, rust, be eaten by termites or need to be painted.

Filtration Systems

Let us eliminate damp, musty odors in your basement or crawl space by drying and filtering the air with our SaniDry Air Systems! The powerful upright model is great for basements or crawl spaces over 40 inches high. When installed in an unfinished area, it ducts dry filtered air into a finished area. It will take four times the water out of the air as a typical dehumidifier, yet used the same amount of energy.

SunHouse Basement Window Enclosure

If you're looking to brighten up your basement with more natural light, or if your basement window wells are dark, ugly, wet and filled with debris, consider the SunHouse basement window enclosure. SunHouse is an attractive, bright, clean solution that will keep rain out, prevent weeds from growing in it and reflect a lot of natural light into your basement. It also keeps most of the wind from blowing against your windows while making a dramatic difference in how your finished basement looks!
