Basement Remodeling in Dundee, 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

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells

Job Stories From Dundee, OR
Water Heavy Insulation Falling Apart in Dundee, OR

This crawlspace had old fiberglass insulation, which had absorbed water, and was falling apart from the water weight. After doing some research they learned that fiberglass insulation is not meant for crawlspaces, there is a better way. Wanting to keep their home insulated the right wat, they called John's Waterproofing. 


Our crew began by removing the old insulation and clearing out debris. We then installed a TripleSafe sump pump to collect ground water and direct it away from the homes foundation to a LawnScape outlet. We than laid down TerraBlock crawlspace insulation and covered this with our CleanSpace vapor barrier. The foundation walls were then covered in spray foam to keep the homes energy costs down. To finish this project we installed a SaniDry dehumidifier and added new vent covers. 

Downspout and High Humidity in Crawlspace. Dundee, OR

The home was suffering from water damage. The Crawlspace had a gutter downspout that had been damaged, causing excess water pooling to occur on the exterior of the home. This added water pressure had caused their crawlspace to experience water quicker than it had been. Their fiberglass insulation was wilting and falling, causing the home above to suffer higher energy costs, and the homeowners were looking for a solution to their water issues, so they called John's Waterproofing. 

To begin out crew addressed the downspout, we added in a discharge line for the downspout that was buried to take the water 40 ft away from the foundation so it could be safely discharged via a LawnScape outlet. Next, all the debris and old fiberglass insulation was removed. We installed a full perimeter drainage system that would collect the groundwater and take the water to the newly installed TripleSafe sump pump and out a discharge line. To insulate the crawlspace we did a layer of our TerraBlock crawlspace insulation. This was sealed in place and we did a spray foam on the concrete foundation walls to insulate to space from dirt floor up. We then encased the crawlspace in a Cleanspace vapor barrier. We added new vent covers to help regulate the temperature, and a SaniDry Sedona to combat any humidity issues.

Downspout Extensions in Dundee, OR

This homeowner was unhappy with how his downspout gutter was pooling water on his concrete patio. He sought help from John's Waterproofing, and our inspector, Gordon suggested a Lawnscape Outlet.

Lawnscape Outlets are underground downspout extensions that connect the gutter downspout to a special outlet sending water away from the patio while camouflaging the end of the pipe. It also has a removable lid for easy cleaning.

Now that our system is in place, Reed is very happy that he no longer deals with pooling water on his patio.
