This crawlspace was unusable. After going in and removing all of the debris, our crew went in and installed Terra Block for thermal insulation and then applied our patented CleanSpace, spray foam, Sanidry sump pump and new drainage lines to create a total clean space environment that can now be used for year.

Here is a wet, soggy crawl space. You can tell by the insulation sagging with moisture and see the evidence of standing water. We went in and cleaned up the space and did a full encapsulation using CleanSpace for the vapor barrier and using Smart Jacks for post stability. Our customer no longer has to worry about moisture or damage being caused in his crawl space.

Basement Waterproofing & Remodeling in Dayton, 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 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 Dayton 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 Dayton, OR
Burst Pipe in Crawlspace - Dayton, OR

This home had been encapsulated a few years back. The homeowners were great with their service appointments and the encapsulation worked well. However, this older home had a surprise for the homeowners. Their old pipes gave out, and one of them burst in the crawlspace. They were able to turn off the water to stop the flow into the crawlspace, but they now had water trapped on top of their vapor barrier and a burst pipe that needed to be addressed. 

When they called John's Waterproofing, they were thrilled to hear we could do fix both the plumbing issues and get their crawlspace water issues handled. To begin we started to do a dry out, and while this happened our plumbing division began to replace the old burst pipe with new piping. We also evaluated their other pipes and ended up doing preventative work and replacing the other pipe systems that were not looking the best. Once the dry out was complete, this home was back to being dry and healthy. 

Finished Basement wasn't Waterproofed first in Dayton, OR

This home had a finished basement that had not been waterproofed before the drywalling and carpeting were installed. This lead to the water slowly creeping behind and underneath these newly installed features. The homeowners first noticed that there was a musty smell in some of the corners. When the carpet was touched here it was moist, and the drywall was a bit 'squishy' to the touch. Knowing that this isn't how it is supposed to be, they called in John's Waterproofing. 

Our crew came in and removed all of the damaged pieces in the basement. We began by digging a trench along the interior perimeter where we installed our WaterGaurd drainage system. This would collect the water throughout the foundation and divert it to a newly installed SuperSump and TripleSafe sump pump which would then pump all of the water out and away from the foundation of the home. We then covered the walls with our BrightWall paneling to help insulation the basement and divert water down to the new WaterGuard. Next ThermalDry wall panels were installed and we laid down our ThermalDry flooring. These materials are non-organic and won't mold or break down. Our finishing department then came through to install trim, and do the final aesthetic pieces that the homeowners wanted. 

Basement Waterproofing in Dayton, OR

This homeowner had leaky basement walls, which kept the space damp, humid, and unusable. Our inspector, Jacob, suggested our patented WaterGuard system, Bright Wall Paneling, and a Super Sump pump. 


Juan and the team quickly went to work to make Jean's basement dry and usable. The process was fast, effective, and cost-efficient. The team installed our WaterGuard System, a perimeter drainage system that will not clog. Bright Wall panels were then installed and are designed to work with our waterproofing system by directing wall seepage into the WaterGuard system and draining to the sump pump. Next, the team put in a Super Sump pump along with an Ultra Sump backup battery to ensure that the sump pump will continue to work even without power.


After our Basement Systems were in place, Jean no longer has water entering into his basement and can enjoy a clean, usable space.
