Basement Remodeling in North Plains, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly remodeled basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include:
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average North Plains contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive basement that lasts a lifetime.

Job Stories From North Plains, OR
Clean Space Without Drainage; North Plains, OR

Customer found us at the Home and Garden Show in Portland. They wanted some waterproofing done, but not the full encapsulation. 

Delfino and Fernando's crews cleaned the crawl space and started the installation. They did the basics, and installed TerraBlock and CleanSpace. They had to replace one of the support beams with our SmartJack to stabilize the foundation and stop the home from caving in that spot. Since this was only a partial encapsulation, we didn't install a pump or discharge line. 

The spray foam was also done to seal up any drafts from passing through the foundation walls. To complete the job the door was replaced with a EverLast Door and they replaces all of the vents creating a tight seal. 

The customer was happy that the job was done in 3 days. Leaving the space cleaner then when they initially started the job. Alice was also very happy to know that we were very accommodating to their schedules. 

Basement to Beautiful Walls in North Plains, WA

In this basement, we installed a waterproofing system, along with basement wall systems. The Waterguard perimeter drain system works to channel water into the Triplesafe sump pump, which will then pump the water out of the basement and into an area far away from the home. The wall systems work to add comfort to the basement, while also acting as a vapor barrier against moisture that can seep in through the porous concrete. They will also channel any water that seeps in higher up on the walls into the Waterguard system as well. This basement is now protected against water, moisture and looks great: the perfect foundation for any basement finishing job.
