Basement Remodeling in Dallesport, WA

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

Job Stories From Dallesport, WA
Wet Foundation Walls in Basement - Dallesport, WA

This older home had damp walls in the basement.  The homeowners had dealt with this,  thinking it was normal for water to get in.  And while it is normal, it is also unhealthy for your homes air and the homes longevity. After seeing John's Waterproofing at a local home show,  the homeowners were ready to see what a healthy basement could be. They called us up and set up their free inspection and estimate. 

To address the water issue,  we began be digging a trench along the interior perimeter. Here we installed a WaterGuard drainage system in a gravel bed. This has a BrightWall system installed on the foundation walls.  This brightens the space,  will not mold, and directs any wall moisture down into the drain system. The drain system naturally grades the collected water to a newly installed TripleSafe Sump Pump,  from here the water is diverted out and away from the home to a LawnScape outlet.  We then installed a SaniDry dehumidifier to ensure this space remains dry and healthy.  

Crawlspace Flooding - Dallesport, OR

This new house was getting near completion, the walls were up, and just final touches were being added. While the crawlspace had a generic 6 Mil vapor barrier installed it couldn't keep the water at bay, causing the home to flood when a big rainstorm hit. The homeowners wanted to know why this was happening and wanting to protect their home, they called in John's Waterproofing. 

To begin our crew removed the 6 mil vapor barrier, fiberglass insulation, and debris. They installed a 3" perforated pipe drainage system around the perimeter to collect the water and direct it to a newly installed TripleSafe sump pump, along with proper discharge. TerraBlock, a high-density foam product was laid over the dirt floor. This aids in insulating the crawlspace and protects the new CleanSpace, 20mil, nylon-reinforced barrier. This is used to isolate each wooden post and anchored to the foundation walls. Lastly, a SaniDry Sedona dehumidifier was installed to ensure this crawlspace and, therefore the home, stayed dry and healthy. With all the vents sealed, Spray Foam insulation was applied to the full wall of the foundation to keep the home properly insulated. Healthy, dry, filtered air helps the homeowners stay comfortable while reducing their utility bills.

Dirt Floor With Water Creeping Up - Dallesport, WA

The crawlspace of this home had water seeping up from the dirt floor in the lower portions. This created some slippery and muddy places under the home and was concerned about the possibility of mold spores taking hold. To get waterproofing help, the homeowners called in John's Waterproofing. 

Our crews began by removing debris from the crawlspace, the crew then evened out the dirt floor to minimize divots and high places under the home. With a more even terrain, they installed a SmartSump pump to collect groundwater and divert it a safe distance away from the foundation of the home. The crawlspace was then covered in a 6 Mil vapor barrier to help keep water from damaging the home. 

High Humidity in Basement - Dallesport, WA

This homes basement was primarily used for storage space and had a good amount of cardboard boxes that were stacked up. When moving some boxes around they discovered some signs of mold growth on some of the cardboard. They wanted to protect their basement and the items they kept down there, so they needed a solution that would waterproof their basement thoroughly. 

For this project, our crew dug a trench along the interior perimeter and installed our WaterGuard drainage system. This will collect all the other and divert it to the newly installed TripleSafe Sump Pump we installed that will take the water out and away from the homes foundation. To keep water from seeping through the walls into the basement we installed our BrightWall Basement Wall Coverings which is a durable, washable, and non-organic paneling. This will make it so that mold growth and rot cannot ruin the system, and will keep humidity and water vapor from passing into the basement. We Also installed a SaniDry Sedona Dehumidifier to ensure that the humidity levels were kept at the ideal levels. 

The homeowners were excited to get to put their storage back and know it would be protected from water. 

Wet Basement in Dallesport, WA

We received a call from a homeowner who had frustrations and complaints of a wet basement. Our crews went out to the home to help. They installed WaterGuard piping system along the perimeter of the basement to intercept water coming into the basement and drains it unseen and safely away to the sump pump. They also installed an UltraSump sump pump in the basement. The UltraSump has a battery operated backup pump in case of power outages, primary pump failure, circuit breakers tripping or the pump becoming unplugged. Now This homeowner can enjoy his dry basement for years to come.
