Basement Finishing & Remodeling in Corvallis, 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 Corvallis 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 Corvallis

In Corvallis, 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 Corvallis, OR
Thermal Dry Flooring in Corvallis, OR Combination Basement

These homeowners had water leaking into their basement and wanted to stop the leakage and prevent further damage. Our inspector, Jack suggested our basement finishing systems because their basement was already partially finished. Of our systems, Allen and Meredith chose our Canyon Beige Thermal Dry tiles and Everlast Wall Panels.

 

Harry and his team swiftly set out to waterproof and finish Allen and Meredith's basement. They installed the Everlast Wall panels, which are neutral-colored wall boards that are immune to mold and moisture damage. We also placed in our Thermal Dry tiles which are beautiful, durable, maintenance-free basement floor tiles. They snap together and come in a variety of colors. The bottom of Thermal-Dry flooring has raised pegs that creates an air space and keeps water vapor from getting trapped under finished floors.

 

Allen and Meredith are very satisfied with their new finished basement and look forward to no longer having water issues.

Vicinity of SW Brooklane Drive, Corvallis in Corvallis
Most of our crawl space was properly dug out, but there is an 8' area that is too close to the floor, and that area is right underneath our kitchen water pipes. I need that 8' long area dug out a couple feet down and about 1' wide, so I can insulate the pipes. If you do free inspections, I would be interested in having our crawl space evaluated as well. Vapor barrier and one area where the dirt has collapsed. Thank you.
Vicinity of NW Norwood Place in Corvallis
We have begun to get water seeping into an area of our basement when it rains. When I had a hose run outside ( about 6in to 1ft from the foundation in problem area) I found about 1/2 bucket of the water had seeped into the basement after about 20 minutes. Cannot see any evidence of water on the basement walls, just on the floor.
