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!

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!

Builder just laid black plastic in strips below, plumber failed to connect toilet/sewage to main line - creating a pool under the house. After they repaired I found they pulled the black plastic down leaving other ground exposed. On top of that plastic was not attached to each other effectively not acting as a barrier. House is two story 3,200 sqf so crawlspace is approximately 1600 feet or less with cement pylons under. 3.5' to 4' clearance in crawlspace.
