Basement Remodeling in Oregon City, 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 Oregon City 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 Oregon City, OR
DIY Sump Pump Fail in Oregon City, OR

We know that sometimes DIY projects seem like the best choice for home repairs and there are several people cheering it on. Unfortunately, a DIY sump pump is an area to stay away from because there is so much more to it then laying a sump pump in a bucket in the crawl space. These homeowners had a DIY sump pump and still had consistent water in their crawl space which caused sagging insulation, and rotting posts. They decided to give us a call after their efforts were not protecting their home's foundation. 

Our design specialist went out and reassured the homeowners that things will get fixed and we would do a crawl space encapsulation for the best protection. Our crew went out and cleaned out the old vapor barrier and sagging insulation. We then lay our Terra Block insulation on the ground that goes under our CleanSpace vapor barrier. The CleanSpace vapor barrier is 20 mils thick and seals the crawl space. With the amount of water this crawl space had, we also went with one of our bigger sumps pumps the TripleSafe that has a three-level pump system that runs the number of pumps based on the level of water flowing in. It also comes with an alarm that will sound if the water level in your crawl space becomes too high. 

This customer was so pleased that the job only took four days and now has the proper protection from water in the crawl space. 

Home for Sale Crawl Space; Oregon City, OR

The soon to be buyers of the home were in the inspection phase, and were told it would be a good idea to have a waterproofing company come out and do an inspection. Upon finding water building up along the walls and vapor barrier in the crawl space.

Carolann did find some water buildup, but not enough to cause much worry. So Gordon and Nathan C went and cleaned out the old vapor barrier and installed new 10 mil vapor barrier. To prevent any future problems they installed the SaniDry Sedona to regulate humidity buildup. They also replaced the crawlspace entryway to keep the area sealed tight.

The buyers were extremely happy with the outcome, and were glad to know they could have it done before the move in date.

Keeping Cement Dry in Oregon City, OR

One of the constants in Oregon is rain. In order to work, our guys have to get creative on occasion. Yesterday our service technician Harry sent me their solution to working outside! The guys used our plastic sheeting (which we normally use for covering floors to not get muddy) and some plywood to create a dry cover for them to install a trench drain system.
