Basement Remodeling in The Dalles, 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 The Dalles 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.

Case Studies From The Dalles
Our inspector went out to check out this new construction project and was greeted with a pretty damp situation. The call for the vapor barrier came...
Job Stories From The Dalles, OR
The Dalles, OR Spray Foam Insulation

This homeowner called John's Waterproofing because her house had a lot of dust in it coming from the crawlspace. In many cases, this is true because 50% of the air that is in your crawlspace is moving to the first floor of the house. After inspection, Bob noticed that the crawlspace did not have a vapor barrier or insulation which is against Oregon code. He suggested that we install our patented Cleanspace encapsulation system as well as Spray Foam Insulation.

Jeff quickly agreed and Gordon and his team began work. They installed Spray Foam insulation which goes on the walls instead of underneath the floor because it works with the CLeanspace system and works more efficiently on the walls. Spray Foam is closed celled so it won't allow water to get through or retain water like fiberglass. Cleanspace was installed on the floors and walls to completely encapsulate it. Cleanspace keeps out moisture, prevents mold and mildew, and keeps out cold drafts. 

Jeff is satisfied with his new system and is grateful that his crawlspace is now up to code.

I need to have my Crawl Space Foundation repaired, and sealed.

I would like a quote on some water leakage in our basement on a recently purchased home. It was built in 1925 and has an unfinished basement. We noticed water leaking through the basement wall when we run the sprinklers that is causing it to smell terrible. We also noticed several other places around the basement with mold growing along the walls on the floor where water may have leaked in the past. Thank you.
