Job Stories From Cascade Locks, OR
Flooding Crawlspace Going onto the Market - Cascade Locks, OR

The crawlspace of This home had a simple 6 Mil vapor barrier installed a few years back, now they were looking to sell the home, and noticed that water was pooling on top of the vapor barrier. Knowing that this type of issue can really delay a sale from occurring, they called up the local experts and we had a Design Specialist sent out. To have the home ready to go on the market, the homeowners opted for our realty package with a Pipe, Pump, and Plastic. 

To begin, our crew removed the old and damaged 6 Mil vapor barrier and the debris. Once the space was cleared out we dug a trench along the interior perimeter. Here we laid down a bed of gravel with a perforated pipe system in a silt sock. This system grades the collected water to a TripleSafe sump system, which then diverted water safely away from the home to a LawnScape outlet. We then brought in a new 6 Mil vapor barrier. This is overlapped and runs up the walls to keep the space dry and healthy for the new homeowners. 

Musty Crawlspace Solution- Cascade Locks, OR

This home was getting ready to be sold, but the sellers noticed their crawlspace was musty and had water present. They wanted the sale to go smoothly, so they called up John's Waterproofing, who has a dedicated Realty Design Specialist. This program allows for a fast track to waterproofing to meet the quick time frames that sellers face. 

Upon investigation we found pooling water and mold spores taking hold. 

To address this issue we began by clearing out the crawlspace. Once the space was cleaned up we installed our three inch drainage system. The perforated pipes were set in a silt sock to keep it from clogging up. The drainage system will collect the groundwater and grade it down to an SuperSump Pump with and UltraSump back up. We then laid down a 6 Mil vapor barrier to ensure the space meets local codes to remain dry and healthy. 

Pools of Water on Top of Old Barrier - Cascade Locks, OR

Taking the opportunity to check out his crawlspace, this homeowner was dismayed to find large areas of pooling water on top of his old vapor barrier. He knew that something was wrong, so after doing some research, and seeing the great reviews and the many years of experience, he decided to call John's Waterproofing.


A Design Specialist was dispatched to the residence and went right to work doing a thorough inspection of both the exterior and interior of the home. Then she sat down with the homeowner and explained what was happening and together they designed a system to fit the homeowner's needs and budget.  


A few weeks later, the crew came out to do the work. First, they pulled the old barrier and debris and installed a drain system that used a 3" perf pipe and graded it into the lowest point of the crawlspace where the water would be collected to a SmartSump and discharged subterraneously to a LawnScape outlet away from the house. They laid a new 6 mil vapor barrier, overlapping the seams a minimum of 18" and running the barrier up the foundation walls to ensure that any water coming in from the footing or walls would be led to the drain system and removed. The homeowner was impressed with the friendly professionalism of the crew and how hard they worked. He also liked that the crew protected his home's floors and walls with plastic from the entryway of the home to the crawlspace entrance in one of the closets.  

Water Creeping through the Walls, Pooling on the Floor - Cascade Locks, OR

Foundation walls are porous, and water can creep through causing pooling. This water became an issue for this home, leading to the wooden posts in the basements to rot and the integrity of the home above was beginning to experience bouncy floorboards and uneven frames for doorways. To reclaim the home's life, John's Waterproofing was called in. 

Our crew began by creating a safe work environment and replaced three of the wooden support beams with SmartJacks. A SuperSump was added in, and a WaterGaurd system was installed to collect groundwater from the interior perimeter. The walls were then covered in BrightWall paneling and a SaniDry Sedona was installed to control moisture in the air. This home is once again safe, dry, and healthy. 

Water Pooling in Crawlspace and Basement - Cascade Locks, OR

This home was originally build with a basement, made of poured concrete. The homeowners had a addition added on, which then created a small section of crawlspace as well. The home dealt with water entering both spaces during the rainy season, and it seemed to progressively get worse as the years passed. Due to the prolonged water damage, the home soon showed evidence of foundation issues, one of the bedrooms experienced a large crack along the floorboards where the lower beams were rotting away. To save their home before more damage occurred, John's Waterproofing was called in to tackle this crawlspace and basement waterproofing job. 

We began by removing any debris that was found under the home. To combat the drooping foundation, we started work in the crawlspace. Three of the support beams were experiencing rot, and the fiberglass insulation was a soggy mess. Once it was cleared out we laid down TerraBlock insulation. We isolated each pier so it couldn't receive more water damage and added in five SmartJacks to provide additional structural support where needed. We then covered the space in Cleanspace, a 20 Mil woven vapor barrier that is sealed against the walls, to fully encase the basement. to add in insulation along the poured walls of the concrete we did spray foam. Finally we added new vent covers and a new Well Duct so that it would be a contained space with nothing getting in. 

Next the basement was tackled. We dug a trench along the interior walls and installed a WaterGuard pipe system to take the water to the TripleSafe Sump Pump we added in. This would pull the water out of the space and get it a safe distance away from the home. Next we added BrightWall paneling to ensure any water getting through the concrete walls would safely get to the sump pump as well. 

This combination crawlspace and basement is now ready for the rain, and the homeowners can rest assured that their home is protected against water damage. 

Wet Crawlspace in Cascade Locks, OR

A homeowner called with concerns about her wet crawl space and the musty odor it seemed to be causing in her home. Our crews went out to fix the problems. After removing all of the debris from the crawl space, our team installed CleanSpace encapsulation system on the floors and walls of the crawl space. This thick liner prevents any moisture or water vapor from coming into the crawl space through the walls or floor. CleanSpace means that there won't be any new mold growth. It also helps to keep out pests. Our crew also installed an insulated vent cover over the open vent of the crawl space. This prevents any cold, hot or humid air from coming into the crawl space from outside. Not only will this help with the musty odors but it also lowers energy costs throughout the home. A SaniDry Sedona dehumidifier was also installed in the crawl space. This dehumidifier eliminates damp and musty odors in the crawl space by drying and filtering the air. Now this homeowner can rest easy knowing that her crawl space in dry and the air in her home is healthier for years to come.
