Basement Finishing & Remodeling in Brush Prairie, 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 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 Brush Prairie 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.

Earthquake & Seismic Retrofitting in Brush Prairie

In Brush Prairie, earthquake risk is a reality. That is why it is critical to have your home properly reinforced and prepared for any seismic event. At John's Waterproofing, we provide seismic retrofitting services on your home or business using metal connectors and other reinforcing methods and materials. The goal is to counteract racking, sliding, and overturning, the 3 major earthquake-induced forces that can damage or ruin your structure.

Job Stories From Brush Prairie, WA
Spray Foam Insulation in Brush Prairie, WA

Robert knew that there were water issues in his crawlspace and sought help from John's Waterproofing. Our inspector AJ confirmed those suspicions and also found that the water was affecting the insulation and posts in the crawlspace. AJ recommended that we install Spray Foam insulation, our patented Cleanspace encapsulation system, and a SaniDry Sedona Dehumidifier. 

Robert agreed with our recommendations and our team, led by Tim, set out to repair the crawlspace. They removed the old, ineffective fiberglass insulation and applied Spray Foam insulation to the walls of the crawlspace. Spray foam works better on the walls because it connects with the Cleanspace encapsulation system for maximum energy efficiency. They placed the Cleanspace encapsulation against the walls and floors to keep out all moisture, prevent mold and mildew growth, and protect against pests and insects. Cleanspace keeps the crawlspace dry and ensures the protection of the structure. Cleanspace comes with a 25-year warranty when installed by John's Waterproofing. A SaniDry Sedona dehumidifier was installed to keep the space conditioned because closing off the vents with Cleanspace makes it a controlled space. The SaniDry Sedona cleans and filters the air while removing all moisture quietly and efficiently. 

Robert is grateful that our systems are in place and that his home is now more energy efficient.

We're building a new home and wish we'd have put in a concrete crawlspace and are looking into the next best option. We'll spray foam insulate April 20th and appreciate you contacting as soon as possible to schedule a visit and estimate. We wonder about how this affects radon, too. Thank you.
