    Building a Finished Basement in Woodburn, Oregon

    Our homeowner was for a real finished look to their semi-finished basement space. Our crews came in and installed our patented Waterguard system, wall systems, and new flooring. This space is now able to be used year-round and has a nice finished look that they can use year-round.    Just covering the walls and adding flooring can often change the entire look of a space.

    By installing The ThermalDry Wall System in this basement, we prevent moisture from seeping in and causing issues like smells, mold and rotting. When installed properly with WaterGuard it will also channel the water into the WaterGuard drain system and out of your basement. ThermalDry has a reflective surface along with bubble wrap like material to help reflect and keep heat in the basement keeping it dry and warm.
