Basement Remodeling in Noti, OR

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

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

Job Stories From Noti, OR
Wet and Smelly Crawlspace - Noti, OR

This homeowner noticed a nasty smell in their home and looked high and low for where it was coming from and finally opened the hatch to the crawlspace and it was clear that that was where it was emanating from.  He called a few companies but after researching their credentials and time in business, John's Waterproofing was an easy decision to get the work done right.


Our System Designer showed up at the home and it was clear from the start that he knew what he was doing. He measured the home and inspected the exterior to look for any signs on the outside that could be contributing to the problem then commenced doing a thorough inspection of the home. In the crawlspace, there was water intrusion on a regular basis and insulation falling with mold starting to grow on the posts and beams. That was where the nasty smell was coming from. 


A few weeks later one of our experienced Installers came out and cleared out all of the debris, old insulation, and damaged barrier.  A perforated pipe drain system was installed around the perimeter and graded to a TripleSafe Sump system at the low point. TerraBlock was laid on the dirt floor and vents were sealed and posts isolated. A CleanSpace barrier was installed and all seams were sealed and it was run up the walls and fastened under the rim joist. A SaniDry dehumidifier was installed to ensure the humidity was controlled to prevent mold growth and the air was filtered for a healthy home. Finally, Spray foam was applied to the rim joist to aid the TerraBlock in insulating the space.

Cold and Damp Crawlspace in Noti, OR

The crawlspace of This home was damp and had high humidity levels. The homeowners also could feel that the ground floor was cold to the touch, and this meant their energy bills were higher than they needed to be, energy was being wasted trying to combat the floor's temperatures. To solve these issues, Johns Waterproofing was called in. 

When we looked at the crawlspace we learned a few things. Firstly the space had a simple vapor barrier draped over the dirt flooring, however since the vents were leaking water into the space, evident by water stains, water was just going over the top of what had been done. Secondly, we learned that insulation had been in the crawlspace since strands of fiberglass could be found, but it must have been taken out by the previous people who worked in this space. To help we cleared out the old barrier. We installed a TripleSafe sump pump to collect groundwater and divert it a safe distance from the home's foundation. We then encased the crawlspace in our 20 Mil thick CleanSpace vapor barrier. This seals under each wooden post and is anchored to the walls. The foundation walls were then sprayed foam to insulate the space against the outside temperatures. We then added in a SaniDry Sedona dehumidifier and new vent covers to get this home dry and healthy! 


Wet Dirt Floor in Crawlspace - Noti, OR

The crawlspace was experiencing wet dirt floors and high humidity. This was starting to damage the wooden beams and posts under the home and the homeowners wanted to put a stop to this before the damage got worse. 

Our crew came out and installed a TripleSafe Sump Pump, capable of pumping out 2,200 gallons of water per hour. They then sealed the space up with Cleanspace, ensuring all of the posts were isolated and protected and that it was secured against the concrete foundation walls. We then added in spray foam as needed to insulate the home. Lastly since the crawlspace experienced high levels of humidity we installed a SaniDry Dehumidifier to combat the moisture in the air. 

Dry Crawl Space for Noti, Oregon

A homeowner gave us a call with concerns about their wet crawl space and the effects it could be having on their home. Our crews went out to the home and installed CleanSpace encapsulation system on all the walls and floor of the crawl space. CleanSpace prevents any moisture or water vapor from coming into the crawl space. This means no new mold growth. It also helps lower energy costs and helps to keep out pests. They also installed a SmartSump sump pump in the crawl space that forms a tight seal around the CleanSpace liner. A SaniDry Sedona dehumidifier was also installed to dry and filter the air in the crawl space. Having clean and healthy air in the crawl space means having cleaner and healthier air in the rest of the home. Now, this homeowner can have peace of mind knowing that her crawl space is dry and healthy.
