Job Stories From Monroe, WA

Looking for a Healthier Home - Monroe, WA

This homeowner was concerned about their health. While they didn't seem to have water in their crawl space, they knew it could use some work. It was a mess under the home, from dusty debris, critter droppings, and fiberglass hanging from the sub-floors. They could smell space while in their living spaces and were ready for a change. We went out and performed a full inspection, and then went over options, landing on a full encapsulation to ensure the space could be healthier all year round.

To begin we cleared the space of the old vapor barrier, insulation, and debris. We then installed a SmartSump as a back up for any odd weather. Where they were situated, water wasn't an issue for them. We then sealed the vents shut and upgraded the exterior entryway, going from a metal well with plywood over it to a Turtl entryway that can be safely sealed shut to keep critters out. TerraBlock insulation was then laid over the dirt floor, and SilverGlo insulation was installed along the foundation walls. CleanSpace came in next, going under each wooden post, anchored to the walls, and sealed along each seam. We finished by installing a SaniDry dehumidifier and air sealing the space. The homes crawl space is much cleaner and healthier now, the owners already are excited to be able to smell the difference.

Basement Water Issues in Monroe, WA

Moisture on the wall, this is what the homeowners began to notice. The owners began to get nervous about what this would be doing for their health. So they called up John's Waterproofing to learn about what they can do for their home so this moisture wouldn't cause long-term issues or worsen.

To begin on the work we dug a trench around the homes interior perimeter. We laid a bed of gravel in this with our WaterGuard drainage system over it. This will be fed water from the walls and collect the groundwater. It then acts as a direct route for this to travel to the lowest point where a TripleSafe sump pump will pump the water safely away from the homes foundation. On the walls we installed our BrightWall paneling, this provides a semi-finished look for the space and safely allows any wall moisture to be guided to the below drainage system. We then installed a SaniDry dehumidifier which will address the moisture issues in the air to the environment will be healthier. The homeowner is happy to know their home is healthier and noticed the space smells fresher already.

Water Damage and Falling Insulation - Monroe, WA

Under this home there was falling insulation and water damage. Mud was over the old vapor barrier and efflorescence along the foundation walls where water had been coming through. The homeowner didn't want to be breathing in this mess so they called up John's Waterproofing to learn how we could make their home dry and healthy. We cleared the crawl space out, and began work on a full encapsulation. We dug a trench and installed a drainage system to collect and guide groundwater to the new SuperSump Plus which pumps the water away from the home. We then sealed the vents shut and spot treated a few places where mold had been showing up. Next we laid TerraBlock insulation along the crawl space floor and brought in the new vapor barrier. This is our CleanSpace, 20 Mil thick woven plastic that wraps under each wooden post, anchors and seals along the foundation walls and along each seam. We then installed a SaniDry dehumidifier and spray foam insulation along the walls. The final step was an Aspen air purifier in the living space to help this home be healthy!
