Basement Finishing & Remodeling in Vancouver, 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 Vancouver 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 Vancouver

In Vancouver, 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.

Daniels St in Vancouver
Basement wall crack

Crawlspace drips water and wetter than usual, especially near the chimney base. Also, some standing water along the drain line. Approx. 1100 sq.ft.

I'm a property manager and one of my rentals (address listed in this request) is leaking in the basement. This is the 2nd water intrusion in the past two months. The first was caused by a broken irrigation line and this last time must have been from the heavy rains. Either way, we need to come up with a solution to keep the basement dry. Thanks!

We are interested in purchasing a home that has a seriously wet basement. When it rains, if the subpump is not working correctly, there will be 2-3" of water there. We would like to have a usable finished basement area available. The house is old and built in the 1900's. Is that a home that is able to be fixed correctly? Also, do you warranty your work? Do you offer extended warranties on the materials and labor to repair? Please give me a call to discuss. Thank you. Also, the house is in Longview. Would that be an area that you would be willing to travel to. Thanks.

We need to have someone go into our crawlspace and give us an estimate on new vapor barrier, whatever else may need to be done, etc. It needs to be cleaned up. Thank you
