Basement Remodeling in Ariel, WA

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 Ariel 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 Ariel, WA
Sagging Insulation in Crawlspace - Ariel, OR

The homeowner had some vapor damage in their crawlspace. All of the fiberglass insulation they had, was sagging and drooping due to the heavy moisture content. They knew they humidity levels must be high since they couldn't find pooling water, so they called John's Waterproofing for some help. 

To help we began by removing the old fiberglass insulation. We then added in a SmartSump Pump to take any moisture content out and away from the homes foundation. Our crew then laid down a Cleanspace vapor barrier that fully seals into a crawlspace to keep the water out. We added in a SaniDry Sedona dehumidifier and then use spray foam to insulate the crawlspace so the home above could maintain its temperature. The home is now dry and healthy, and properly insulated in the crawlspace. 

Crawl Space in Ariel, Washington is Now Dry

A homeowner had called after getting fed up with the cold floors, high heating costs, a pretty noticeable draft and unpleasant odors throughout their home. So our crews went out to the house in Ariel, Washington to help this homeowner. The problems were originating from the dirt crawl space. Our crews first removed all the rocks and loose debris from the crawl space and leveled out the ground. Then they installed CleanSpace encapsulation system on all the walls and floors of the crawl space. CleanSpace prevents any moisture or water vapors from coming into the crawl space from the walls or floor. This means no new mold growth. It also helps to keep floors warmer and lower heating costs. They also installed a SmartSump sump pump. This sump pump is designed just for crawl spaces with a liner and lid that forms a tight seal around the CleanSpace liner. The SmartSump also has a built-in WaterWatch alarm system to alert the homeowners if there's ever a plumbing leak so that the problem can be fixed before any damage has occurred. With these products working together, this homeowner can enjoy their healthier home for years to come.
