Basement Finishing & Remodeling in Wilsonville, 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 Wilsonville 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 Wilsonville, OR
Unhealthy Crawl Space; Wilsonville, OR

Denise and her roommate, Carl, called due to them constantly being sick. Vincent went out and found mold growth in the crawlspace, which can make the air quality very poor and carriers allergens into the home. 

Cleaning up the space was first priority, due to water building up in the fiberglass insulation. Which was causing the black mold growth. After completely cleaning out the space, the crew installed the TerraBlock, and had to isolate the piers. So that when they laid down the CleanSpace, they can put it under the posts to seal the space completely. 

For extra precaution, the crew made sure to install the SaniDry Sedona dehumidifier, and the TripleSafe sump pump. Ensuring that the humidity levels would be regulated. And that any water to get in, would be discharged out. 

The customers were happy and saw results immediately. They were able to breath with ease again. Encapsulating the space, reassured the customers that it had eliminated added allergens from the crawl space. 

Cleanspace in Wilsonville, OR Crawlspace

Derek called John's Waterproofing because his crawlspace had water in it. Our wonderful inspector, Jack came out to take a look and based on Derek's situation, he recommended installing our patented Cleanspace encapsulation system, a Super Sump pump, and a Lawnscape outlet. Once our suggestions were approved, Juan and his team quickly set out to waterproof Derek's crawlspace. 

They began by installing our Cleanspace encapsulation system that comes with a 25-year warranty and is patented against moisture, mold and mildew growth, and acts as insulation. It is installed over the floor and walls of the crawlspace in order to keep out negative exterior elements. The team also installed a Super Sump pump which fits perfectly with the Cleanspace system and is designed to alert the homeowner if water levels get too high. We connected the Super Sump line to a Lawnscape outlet. Lawnscape outlets recieve the crawlspace water and are installed on the exterior of the house to keep the excess water from affecting the foundation. Lawnscape outlets come in three different versions for whatever the need may be.

Now that our systems are in place, Derek can rest assured knowing that water problems will not be an issue in his crawlspace for years to come!

Hello, We have some standing water(couple inches) in our crawlspace after heavy rains. It will dissipate after a day of dry weather. The house was built in 2005 and has a low point drain pipe, unfortunately, the standing water never makes it to the low point drain pipe. I'm interested in getting an estimate. Thanks.
