Crawl Space Encapsulation in Portland, OR

The homeowners of this 1991 Portland, Oregon home quickly called TerraFirma for help when they realized an unpleasant smell coming from their crawl space.

After a thorough evaluation, our System Design Specialist determined that the crawl space had standing water and contaminated insulation. To address the issue, he suggested the installation of the VaporLoc Elite® Encapsulation System, SuperSump Plus, and Waterguard Drain Outlet.

With a plan in place, TerraFirma installed a full crawl space encapsulation to make sure this crawl space stays dry and clean!

Crawl Space Encapsulation in Issaquah, WA

After years of neglect and water damage, this crawl space in Issaquah, WA hadn't seen a good day in a long time. From the rust on the nails in the wall to the mildew-infested insulation, the water damage in this crawl space was instantly noticeable from anyone who stepped inside.

Once the homeowners noticed that a "mildewy smell" in the first floor of their home was coming from the crawl space, they did the right thing and set up a free estimate with TerraFirma. Our experienced System Design Specialist Drew Fry assessed the problem, and he concluded that to mitigate future water damage, the crawl space would need a TripleSafe Sump Pump to properly drain water away from home. We also recommended that we install drainage matting to prevent water from seeping through and pooling in the crawl space, as well as VaporLoc to prevent moisture intrusion.

With a plan put in place, the TerraFirma team mitigated water damage and encapsulated the crawl space in three days! 

Crawl Space Encapsulation in Issaquah, WA

The state of Washington is known for its heavy rainfall, and that fact is still true in Issaquah. Like most homeowners, this couple had lived in their home for ten years but never bothered to look at their crawl space. After seeing one of our commercials, the homeowners decided to give TerraFirma a call to schedule to their free inspection, so they could learn for themselves what's happening under their home.

When our System Design Specialist inspected their crawl space, he noticed water pooling throughout, which means that water that was flowing into the crawl space had nowhere to exit.

After talking to the homeowners, our Specialist advised for them to waterproof their crawl space by installing a Triple Safe SumpPump for drainage, and VaporLoc Elite lining and drain tile matting to help prevent moisture from causing water damage to their wooden joists.

With a plan put in place, our crew waterproofed this crawl space in Issaquah, WA in two days!
