This basement had water problems for many years without anyone addressing them. As you can see in the photo the walls are dirty and crumbling in some places and the floor has muddy standing water. At this point, our crew had already started digging to install our WaterGuard drain system along the basement wall. It drains the water down to a sump pump to be pumped out and away from the home. We also installed our BrightWall paneling system that makes the basement so much brighter and is easy to wipe off the walls. Always leaving a clean and fresh feeling in the basement.

Basement Remodeling in Scappoose, 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 Scappoose 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 Scappoose, OR
Cold Floors and High Energy Bills - Scappoose, OR

This home had high energy bills and very cold floors. The homeowners had been working on upgrading their home to lower energy bills; replaced old windows, switching to energy efficient appliances, and they were now ready to address their crawlspace. 

Our crew went out and began with a general debris removal. Once the space was cleaned out we laid down out TerraBlock crawlspace encapsulation. We than laid down out CleanSpace vapor barrier. This is wrapped around each wooden post and anchored along each wall to create a water tight seal. One the foundation walls we than insulated with Spray Foam. Each vent cover was changed out, and this home was now properly insulated. The homeowners were ecstatic with how quickly this lowered their energy bills. 

Caked Mud in Crawlspace - Scappoose, OR

When going to sell a home, presentation is important, even in a crawlspace. A clean look goes a long way to ensure potential buyers that a home has been cared for and is in good order. One of the items that an appraiser will look over is a crawlspace or basement. Having these areas waterproofed and upkept will protect a homes integrity and life. This homes crawlspace had been waterproofed, but that was years and years ago, and before going to sell, they knew they would need to redo their crawlspace. What they had was now caked in mud, had the vent covers chewed on, and evidence of critters. 

To help them sell their home we came out and cleaned out the old vapor barrier and dried the space. We added in a SuperSump pump that would collect water from under the home and direct it out and away from the home with a newly installed discharge line. We then covered the crawlspace with a new 6 Mil vapor barrier. Lastly we installed new vent covers to help keep critters out. The home was now ready to go!  

Crawl Space, Scappoose, OR

Katy in Scappoose, Oregon is severely allergic to mold and while she was searching the internet for ways to her maintain a healthier, allergen-free lifestyle she came across the John's Waterproofing website and saw that our company is accredited with the American Lung Association so she gave us a call to see what waterproofing was all about. Kayla, in our call canter, explained to Katy that half of the air on the first floor of her home came from underneath her house and that waterproofing encapsulated crawl spaces, eliminating dust, mold, and allergens from entering the home. Katy was intrigued and soon after our Design Specialist Vitaliy was out to her house to take a look. He went underneath her house, took pictures of the water damage and debris that was down there. Vitaliy thoroughly explained what our company did and the benefits of encapsulating her crawl space and they both agreed this would be the best option. 

Shortly after, Foreman Tim and his crew were out to Katy's house, cleaned out the crawl space including removing the water-filled, sagging insulation and then installed a SaniDry Sedona Dehumidifier to stop any further moisture. Installed a SaniDry XP sump pump that pumps out any continued water from the crawls space and replaced the insulation with Spray Foam insulation. Katy now has a clean, dry crawl space that runs efficiently and is guaranteed to provide her with allergen-free for may years. We were thrilled to help provide Katy with this peace of mind and we definitely appreciate our customers. 

Insulation Issues, Scapoose, OR

Katy who lives in Scappoose, Oregon called because she is severely allergic to mold and was concerned about the mold issue she knew was happening. She had already found out there was moisture in her crawl space. And sure enough, when our Design Specialist, Vitaliy went out to see her there definitely were puddles of water, moisture-damaged posts and wet, sagging insulation. 

Here at John's Waterproofing Company breathing clean dry air is a top priority. Being accredited with the American Lung Association, we understand the importance of clean air and our customer's wellness means a lot to us.

In just a few short days our top-notch crew was able to go out to Katy's house, clean out all debris, moisture, and took out all of the insulation and did repairs and moisture control to the posts. We installed a TripleSafe sump pump, CleanSpace encapsulation, SaniDry Dehumidifier, and Spray Foam Insulation. This encapsulation guarantees a dry crawl space environment which is also low maintenance and very energy efficient. 

Katy can rest assured that the air coming into her house from her crawl space is dry and mold-free. She is breathing much easier and healthier and we were glad to help. Katy also knows we are just a phone call away and will be out once a year to maintain the health and efficiency of her crawl space. 

Cleanspace Installation in Scappoose, OR

This homeowner had standing water in her crawlspace and found John's Waterproofing through the internet. She set up an inspection with Vince and he came out to her house to take a look. From what he saw, he suggested that we install our Cleanspace encapsulation system, spray foam insulation, and a Triple Safe sump pump. 

Pam agreed to our suggestions, so Ramon and his team quickly began the waterproofing process. We removed the old 3 mil vapor barrier and installed Cleanspace. Cleanspace is a 20 mil thick, 7 different layer polyethylene composition. It has a 25-year warranty and is patented against all moisture, mold, mildew, insects, and pests. Our spray foam specialist, Demetrius, then came in to install spray foam insulation on the walls above the cleanspace. These two products work together to form a solid barrier of insulation and waterproofing. Finally, we installed a Triple Safe sump pump which is a three-pump system designed to handle all pumping requirements and work even when the power goes out.

Pam is satisfied with her new waterproofing system and no longer worries about water issues.
