Basement Remodeling in Underwood, WA

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly remodeled 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 Underwood 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 Underwood, WA
Water Crawls Down Driveway and Into Garage - Underwood, WA

This home had an issue with water running down their driveway and creeping into their garage. In an effort to solve this issue the homeowners first updated their old garage door, which was better sealed when it was closed, but then pooling on the outside of the garage door occurred which came in when the door opened. To keep this issue from happening, the homeowners then called up John's Waterproofing. 

To combat this issue our installation crews dug a trench along the exterior near the garage doorway. We then installed a TrenchDrain here to collect the water and grade it along the side of the home and safely out and away from the home's foundation and out via a LawnScape outlet. The garage of This home will now stay dry and healthy. 

Old Vapor Barrier Chewed on by Vermin - Underwood, WA

This home had minor water issues and had a 6 Mil vapor barrier installed a few years prior. Upon recent inspection, the homeowners discovered that the vapor barrier had been chewed through in multiple places, and there were other signs that critters had taken up residency in this crawlspace. To stop this issue before it escalated, the homeowners called in John's Waterproofing.

Our crew began by removing the old and damaged vapor barrier. We then laid down our 20 Mil thick CleanSpace vapor barrier. This is tearing and rip-resistant and comes with a twenty-five-year warranty to back it up. This is sealed along the post footings, and anchored along each wall, to ensure it has a tight seal throughout, keeping both water and critters out. To finish up this project we replaced the vent covers since they show signs of critters chewing them as well. 

Basement Doorway has Flooding - Underwood, WA

This home had a well finished basement. One side of the basement was build into a hillside, and the opposing side had a large doorway that opened up to their backyard. The issue was that the home had a lot of water build up around this exterior doorway when it rained heavily. This water pressure was pushing its way into the basement and the homeowners were worried about the long term damage that their basement would face with this water exposure. To put an end to this, the homeowners called John's Waterproofing. 

Our crew inspected the basement and found no other way for the water to be getting in, it was just the doorway that had some water issues. To combat this we dig a trench in the cement back porch and laid a trench drain to collect the water that had been pooling here. We had a drainage pipe then divert this collected water and taken a safe distance away from the home. This will ensure that the basement can stay dry throughout the seasons.
