Basement Remodeling in Gladstone, 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 Gladstone 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 Gladstone, OR
Wet and Filthy Crawlspace - Gladstone, OR

The homeowner was aware he had water intrusion problems and after doing his research on area contractors, he chose John's Waterproofing due to their many years of being in business and numerous positive reviews.


Our System Designer arrived at the home a few days later and commenced a thorough inspection of the crawlspace and exterior around the foundation to help the homeowner understand what was going on and what we would do to fix it. It was discovered that the downspouts around the home were discharging too close to the foundation causing an unnecessary amount of water pressure on the foundation of the home.   


Our crew was dispatched to the home a few weeks later to get the work done. They removed the dirty old barrier and debris from the crawlspace and installed a full perimeter drainage system around the interior of the crawlspace consisting of 3" perf pipe in a silt sock and terminated to 2 lowest spots of the crawlspace. Because of the large sq footage, it was necessary to install 2 SuperSump pumps at these low spots. Downspouts were addressed with 130' of 3" PVC pipe and Sumps were discharged to the downspouts drainage, terminating at 2 NDS drains. An Everlast door replaced the rotting wood door at the exterior access point. Lastly, a new 6 mil plastic barrier was installed on all dirt surfaces and fastened to the foundation.


This homeowner can now rest assured that his crawlspace will be dry and is warrantied for 10 years. 

Damp Basement in Gladstone, OR

These homeowners had water leaking into their basement through the foundation walls. The leak had gotten worse and water would pool along the floor. For help, the homeowners called in John's Waterproofing.


Our crews began by installing our WaterGaurd drainage system along the interior parameter of the basement. We also installed our ThermalDry wall panels to divert water down to this drainage system. From here water is directed to the newly installed SuperSump plus and then pushed out and away from the home. This home will now be dry and healthy!

Cleanspace Encapsulation in Gladstone, OR Crawlspace

Toni saw one of our service trucks out and about working on another home and knew that his crawlspace needed attention. He called John's Waterproofing to set up an inspection with our inspector Eric. Eric noticed that there was a lot of water intrusion and mold that needed to be addressed. He suggested installing our patented Cleanspace encapsulation system, a Triple Safe sump pump, and Mold-X.

Toni happily agreed, so Demetrius and his team went to work. They first had the mold removed so it was safe to continue our process and proceeded to put in an application of Mold-X to prevent mold from coming back. We then installed our Cleanspace encapsulation system that is patented against water and moisture intrusion, mold and mildew growth, and insects/pests. When installed by John's Waterproofing, Cleanspace has a 25-year warranty. We also placed a Triple Safe sump pump that works perfectly with the Cleanspace. The Triple Safe is a three-pump system designed to meet all pumping requirements. It will even continue to work when the power goes out with its third backup battery pump.

Toni is satisfied with his new system and no longer has to worry about future crawlspace repair necessities.
