Basement Finishing & Remodeling in Warren, 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 finished 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 Warren 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 finished basement that lasts a lifetime.

Job Stories From Warren, OR
Clean Space Encapsulation in Warren, OR

This homeowner was experiencing standing water and falling insulation in his crawlspace. The lack of effective insulation leads to a drafty home and larger energy bills. Our inspector, Bryan, advised the installation of our patented Clean Space system, replacement of falling insulation with Spray Foam Insulation, and  Smart Sump pump.

Manuel and his team immediately set out to waterproof and insulate Mike's crawlspace. They began by removing the old, ineffective insulation, and replaced it with Spray Foam Insulation which doubly acts as insulation and waterproofing. Spray Foam creates a powerful airtight seal that provides more benefits than normal fiberglass insulation. The team then installed Clean Space, our patented vapor barrier system that transforms crawlspaces into cleaner, drier, healthier, and more energy-efficient spaces. The Smart Sump pump was then installed to keep all underground water from entering the crawlspace.

After our systems were in place, Mike was able to enjoy a healthier, more energy efficient home without the threat of water intrusion.

Vicinity of S. Morse Road in Warren
Rainwater flows toward my back door into a drain going under the house and ends up in a small crawl space. I can't use my pantry for storing my garden onions and potatoes because of the moisture coming up from under the house. My brother suggests a sump pump, but I'm not certain that will take care of the problem in my pantry.
Vicinity of Stone Road in Warren
There seems to be water underneath the house in the crawl space. I haven't been down there myself but I had a heating and air installer that did and he mentioned it. I'm not sure if I have a sump pump already down there or not. I definitely need someone to come and assess the water issues for me.

What would it cost to replace the vapor barrier in our home?
Vicinity of Bayview Rdg in Warren
A newer stemwall was poured over an older concrete footing with the join never sealed, allowing water to seep through. This is in a garage.
