Job Stories From Harrisburg, OR
Slanted Floor Showing Foundation Issues in Harrisburg, OR

Water damage under the home can slowly creep into the foundation of a home. When it occurs slowly, it is much easier to overlook until a more serious issue is obvious. This home had a slow water issue that led to multiple wooden beams having mold and rot which was evident from the sloping floors in the home. 

We began by removing the excess dirt in the crawlspace and then turned to address the foundation issues. We installed ten SmartJacks which can adjust heights should any further issues be present. To finish we then laid out a new six mil vapor barrier to keep water from damaging the home again. 

Large Crawlspace Has Pooling Water Issues - Harrisburg, OR

This large crawlspace had an old vapor barrier that was caked with mud. Due to the uneven dirt floor, there were places present with pooling water that was surrounding some of the wooden posts that support the home above. Because of this, the above flooring had some structural issues where the floor was uneven. To find an issue with their water intrusion and their structural integrity, the homeowners called in John's Waterproofing.  

Our installers came out and began by removing the old vapor barrier and other debris from under the home. We had to replace ten wooden posts with our SmartJacks to ensure the home would be stable. We then installed two sump pumps, one on each side of the crawlspace, a TripleSafe, and a SuperSump. This work to divert groundwater a safe distance away from the home and out via a LawnScape outlet. The space was then encased in our Cleanspace vapor barrier which is inserted under each post and seals against the walls so that a sold seal is established. Our installers then installed new vent covers and some spray foam where needed. This home will now be dry and healthy!

Small Pooling becomes Flooding Overnight - Harrisburg, OR

When a big rain storm hit, the homeowners knew they needed to keep an eye on their Crawlspace. They had been used to a small amount of pooling water in their crawlspace, and expected it. However, since it had been left untreated, they were not prepared for how quickly the situation could get worse. Overnight, their small pools of water, became a full flooding situation. The water had filled the crawlspace and was penetrating the wooden posts under their home. If left unchecked, this issue would begin to cause wood rot, mold, and could permanently damage the house. The homeowners knew they could delay waterproofing any longer, and they called Johns Waterproofing to get a free estimate for a full crawlspace encapsulation. 

To fix their issue, we began by drying the crawlspace out, we needed a dry foundation so we could prevent damage while we worked. Our install crews removed the debris and added in a Smart Sump and UltraSump under the home. These systems would collect the water from under the home and direct it away from the homes foundation. To keep moisture from getting into the crawlspace, we then laid down our TerraBlock and Cleanspace barriers. These non-organic materials work together and cannot mold, they are tear resistant and are sealed under each post and along the walls so that nothing can get into the home. We then added new vent covers so that nothing could enter the crawlspace via the vents. 

The homeowners were so pleased with their newly encapsulated crawlspace and were happy that they didn't need to worry about water damage under there home any longer. 

Dry Crawlspace in Harrisburg, OR Crawlspace

A homeowner in Harrisburg called our office to see what we could do for their wet crawlspace. Our crews went out and first cleared out all debris in the crawlspace. They then installed CleanSpace encapsulation system. CleanSpace will keep any moisture or water vapors from coming into the crawlspace through the floor or walls. This will help lower heating costs for the homeowner and improve the overall health of the crawlspace and rest of the home. Our crews also used Spray foam insulation. Spray foam insulation won't be affected by cold, warm or moist air. It fills in every crack, space, and void, helping reduce energy costs and reduces the risk of mold. A CleanSpace Vent Cover was also installed over the crawlspace vent. This keeps outside air where it should be, outside. This means that no cold, hot or humid air is coming into the crawlspace and causing mold issues. A SuperSump sump pump was put in the crawlspace as well. The SuperSump sump pump not only has a powerful pump that can pump 2,650 gallons of water an hour smoothly and quietly but also has a built-in WaterWatch alarm system that will alert the homeowner to a water problem before any damage is done. There is also now a SaniDry CX dehumidifier in the crawlspace to filter out the air, removing any moisture in the air and ensuring a dry and healthy crawlspace and home. Our teams also installed Smart Jack crawlspace stabilizer to stop settling and raise the floor back to the proper level. This means no more sagging floors or inoperable doors. The homeowner now has a dry crawlspace and a healthier home for years to come.
