The before picture shows evidence of water intrusion under the floors and behind the baseboards. The after photo shows our Thermal Dry system preventing any water from getting to the drywall that will be installed after our systems are in place.

This home's crawlspaces old vapor barrier was not installed properly and the water had been pooling under it, on it, and the moisture was being absorbed by the old fiberglass insulation. This passageway under the home had the old wooden frame rotting under the vapor barrier. To address this waterproofing issue we installed our dimpled drainage matting, insulated it with TerraBlock, and then sealed it all in with Cleanspace. The after photo here is from the work-in-progress stage, showing the layers that go into this encapsulation.

Basement Remodeling in Corbett, 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 Corbett 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 Corbett, OR
Bringing A Crawlspace up to Code in Corbett, OR

As a homeowner gets ready to sell their home, they need to ensure that the home is up to code, and over the years a home can begin to settle. This home settled over the years, leaving their crawlspace with an inadequate amount of room for someone. To bring it back up to code before going on the market, the homeowners called in Johns Waterproofing. 

Our crew did a dig out, removing in total, twenty cubic yards of dirt to have this crawlspace compliant with its local codes. We then installed a 6 Mil vapor barrier to protect against water issues. This home will now be ready to go onto the market. 

Waterguard Perimeter Drain in Corbett, OR Basement

Three homeowners had water migrating through the walls in their basement and called John's Waterproofing out of concern of the negative effects. Our inspector, Travis came up with the perfect solution to help them solve their water issues. He suggested installing Thermal Dry Walls, Bright Wall panels and our patented Waterguard system.


The homeowners quickly agreed to Travis' suggestions and Delfino and his team started waterproofing the basement. They began by installing Thermal Dry walls which improve comfort and energy efficiency by reflecting heat back into the basement space. They then installed Bright Wall panels that turn bare basement walls into bright, beautiful finished walls. Bright Wall panels never need paint or any other maintenance and are designed to work with the Waterguard Perimeter Drain system by directing wall seepage into the drain. The drain then channels the water to the sump pump.


Now that our systems are in place, Ben no longer has water entering into his basement and can enjoy his new, dry and usable space.
