This homes downspouts had a slight extender, but it was just dumping water in the yard, causing the yard to flood and water mold to grow in the downspout tube. To address this issue we dug a trench along the side of the home, extended the downspout into the ground and installed a pipe system to safely send the water away from the foundation to a LawnScape outlet.

This basement was semi-finished with some rooms left bare for general storage, and others finished for a bedroom, craft room, and bathroom. Over the years, water began to come in through the foundation along the rim joist and the floorboards. It was a slow intrusion, but over time became water mold and an odd odor took hold of the space. To fix up the basement, we removed the damaged portions of the basement walls and flooring. A full parameter WaterGuard drainage system was installed to collect water and grade it to a TripleSafe sump pump. On the unfinished walls we installed CleanSpace panels, and the finished spaces we insulated with a ThermalDry radiant barrier. Our finishing crew came out afterwards to re-finish the livable spaces for the homeowners to enjoy once more.

Case Studies From The Dalles
Our inspector went out to check out this new construction project and was greeted with a pretty damp situation. The call for the vapor barrier came...
Job Stories From The Dalles, OR
Small Crawlspace/Big Problems - The Dalles, OR

Though small in square footage, frequent flooding had left this crawlspace in bad shape. The flooding had damaged the wood posts, and the old vapor barrier, and there was lots of debris. Our system designer went down to survey the damage and take pictures to show the homeowner. After telling the homeowner what his options were, he opted for encapsulating the crawlspace.

To begin our crew removed the 6 mil vapor barrier, damaged fiberglass insulation, and debris. Then 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 protecting the new CleanSpace, 20mil, nylon-reinforced barrier. This is used to isolate each of the newly installed galvanized steel Smart Jacks and anchored to the foundation walls. Lastly, a SaniDry dehumidifier was installed to ensure this 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 insulated and keep utility costs down.

Water in Basement - The Dalles, OR

Basements are a great added space for many homeowners. Whether it is finished and used as living space, or unfinished and used for storage, the square footage is nice to be able to utilize. However, if water threatens a basement, it can be rendered unusable. To reclaim this basement after mold started growing on their stored items, the homeowners called in John's Waterproofing. 


Our crews went out and began by digging a trench along the interior parameter, we than installed a WaterGuard drainage system which would divert all water towards a newly installed SuperSump pump with an UltraSump backup. This water is than pushed out and away from the home via discharge line. To ensure water moisture from the foundation walls would be handled properly we also installed ThermalDry wall panels for a waterproofed and clean look. 

Water Damage to Basement Floor - The Dalles, OR

This home had a large crack on their basement floor. This was allowing water to seep up into the basement and pool in the corners. While the basement was mainly used for storage, the pooling issues would lead to them needing to move items around when there was a heavy rain, and the homeowners were worried about the damage that was happening to their items due to the high humidity from so much water. 

To fix this issue our install crew dug a trench along the interior walls of the basement and added in out WaterGaurd XL pipe system to collect the water, this all drained to the newly installed SuperSump that would safely take the water away from the home. To address the large crack in the floor, we sealed up the five foot long crack so it wouldn't cause the home any more distress. To finish this basement off right we then added in a SaniDry Sedona to take the excess humidity out of the basement, creating a healthy environment. 

The homeowners were so happy to reclaim their basement without the threat of water damage. 

The Dalles, OR Spray Foam Insulation

This homeowner called John's Waterproofing because her house had a lot of dust in it coming from the crawlspace. In many cases, this is true because 50% of the air that is in your crawlspace is moving to the first floor of the house. After inspection, Bob noticed that the crawlspace did not have a vapor barrier or insulation which is against Oregon code. He suggested that we install our patented Cleanspace encapsulation system as well as Spray Foam Insulation.

Jeff quickly agreed and Gordon and his team began work. They installed Spray Foam insulation which goes on the walls instead of underneath the floor because it works with the CLeanspace system and works more efficiently on the walls. Spray Foam is closed celled so it won't allow water to get through or retain water like fiberglass. Cleanspace was installed on the floors and walls to completely encapsulate it. Cleanspace keeps out moisture, prevents mold and mildew, and keeps out cold drafts. 

Jeff is satisfied with his new system and is grateful that his crawlspace is now up to code.
