Basement Remodeling in Gervais, OR

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home.

Our Products Include:
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

Job Stories From Gervais, OR
Waterproofing and Setting A Basement up to be Finished in Gervais, OR

These homeowners were preparing to finish their basement. They were looking to create an extra bedroom, bathroom, and home office out of their basement. While they were looking to do this over a few years, there were ready to start this process properly with a waterproofing job. 

Our crew began by digging a trench along the interior parameter, where we installed a WaterGuard drainage system. This would collect ground water, and the water from the walls as well. To direct water to this system we installed a ThermalDry foil-faced wrap. This would reflect heat back into the space to help control energy costs and also provides waterproofing to protect this homes future investments. The drainage system would then push water to a newly installed SuperSump plus, and the water then pushes water out and away from the home to a new LawnScape outlet. This home is now fully waterproofed and will be ready to be finished. 

Water Build up by Downspout - Garvais, OR

While the crawlspace had been waterproofed, the homeowners had figured their home would be set, but after a few windstorms, the two downspouts by their home were dented and damaged. This caused an excessive amount of water to pool near the home. And while this wasn't creeping under the home, the water pressure was a worry for the longevity of the foundation of the home and was a safety concern as they had mud pits to wade through to get into their home now. To solve these issues they called in John's Waterproofing. 

To address this problem, we opted to bump their downspouts into the ground and hook them up to the buried pipe that took the crawlspace water out and away from the home to their LawnScape outlet. By burring the downspout lines there is no more need to worry about people running into the spouts, it directs all of the water a safe distance from the home, and that portion of the gutter system no longer need to worry about wind storm damage. The change was instant, the homeowners are so happy that they no longer need to wade through mud to get indoors. 

Basement Leaking - Gervais, OR

This home had a partially finished basement with half of the space unfinished and used for storage plain concrete poured walls. The other half had been waterproofed and had a finished bathroom, a canning room with floor-to-ceiling shelving, a home office, and a spare room. As the family's needs changed, they decided that their basement was due for a change as well. To ensure the job was done right and would protect their home they called John's Waterproofing. The goal was to tear down the walls to the spare room and finish the rest of the basement to make an open floor plan and a game room. 

Our crew came out and began by inspecting that the finished portion of the basement was still well protected. Our crew only found some minor leak issues with the window wells in the office so they added new WellDucts, and then moved on to tear down the unwanted walls. Then they dug a trench along the perimeter of the interior of the unfinished basement and installed WaterGuard to direct water to the new SuperSump Plus we installed. These were hooked to a discharge line that would run the water out and away from the home's foundation. We added ThermalDry Walls and ThermalDry carpet squares. These products are made of non-organic materials so they will not mold or rot. Both work to direct water to the sump pump and also help to maintain the temperature in the basement to create a comfortable environment. The family was very happy with their finished space, it flowed well with the home's layout and made a great new addition for their usable space. 



No More Water Intrusion for Crawlspace in Gervais

A homeowner had called with complaints of water intrusion in their crawlspace. Our crews went out to the home in Gervais to figure out the best solution. Our teams replaced the vapor barrier in the crawlspace to prevent moisture in the air from creating mold issues. A SmartSump was also installed in the crawlspace to make sure there are no future problems caused by plumbing leaks. In the event of a plumbing leak, the built-in alarm system in the SmartSump sump pump will alert the homeowners to the problem. The SmartSump will also drain away the water from the plumbing leak until the problem is fixed. Now the customers have a dry, healthy crawlspace and peace of mind.
