This homes old sump pump couldn't keep up with the homes water issue. The space would have puddles pop up and the walls would leak. Since these issues left the space unusable for storage, the owners were in search of a solution. This is how they came to find John's Waterproofing. We removed the old pump and installed our own full interior perimeter drain system using WaterGuard. This collects ground water as well as any water from the walls and channels it to the newly installed TripleSafe sump pump. This machine then pumps the water safely away from the home. Along the walls we than installed our BrightWall paneling, this will not mold or mildew, and it provides a semi-finished look to the space. The owners are so pleased to have their basement fully usable now and look forward to not having to worry when it rains.

Job Stories From Kenmore, WA
Crawl Space Work Before Being Sold - Kenmore, WA

This home was on the brink of being sold, but the buyers wanted to crawl space to be addressed before they would finalize paper work. So the realtor referred the sellers to John's Waterproofing. The Realty Response program helps to meet the strict timeframe that realty projects face, and we scheduled a free inspection. Upon inspection it was found that the old vapor barrier was battered and covered with puddles of water. To stop puddling water and get this space back up to code, the repair plan was selected: a pipe, pump, and plastic. 

We removed the old vapor barrier and debris that was present. Once cleared out we dug a trench around the internal perimeter. Within this we installed a perforated pipe within a silt sock. This will collect groundwater and send it along to the lowest point of the space. Here a TripleSafe sump pump will collect and direct the water safely away from the home, so no more stagnant water will live in this crawl space. We then laid down a new 6 Mil vapor barrier. This is anchored along the walls and we overlap the edges to help keep water down. With the crawl space addressed the sale was able to proceed.
