Secure Your Crawl Space with TerraFirma

Crawl Space Encapsulation Solutions from TerraFirma

Give TerraFirma a call and schedule a free inspection today

It is not common knowledge that even when a house is still and quiet, the air inside is always moving. As warm air rises and leaves through windows or attic vents, cooler air from underneath the home moves upward to replace it. This process happens naturally in just about every house, and it's known as the "stack effect". The cooler moist air from underneath is coming from your crawlspace. A place that might have mold, rot, or nasty stuff like rodent droppings. The stack effect is pulling that air right through your home and you can do something about it.

TerraFirma has fixed all kinds of crawlspace problems including water damage, animals, and poor construction. We will clean up the mess, address moisture problems, make structural repairs, and improve energy efficiency. It does not matter if your crawlspace is tiny or large, we can make it a clean healthy space for years to come.

Before and After
  • Crawl Space Encapsulation in Roseburg, OR
    Crawl Space Encapsulation in Roseburg, OR

    This Roseburg crawl space had mold growing from unwanted moisture lurking inside it. To keep their crawl space dry to stop the mold from spreading, the homeowner reached out to TerraFirma. 

    Our System Design Specialist came out and recommended installing the VaporLoc Elite Bundle, MoistureLoc, Everlast Door, Drain Title, and TripleSafe Sump Pump in the crawl space to create a full perimeter drainage system.

    While these keep the crawl space dry, these products will also keep energy costs low and improve home air quality.  

  • Crawl Space Encapsulation in Roseburg, OR

    This Roseburg crawl space had suffered from not one but two rodent infestations! Rodents can use crawl spaces as a breeding ground, deteriorating air quality and impact a homeowner’s health. Luckily, they called TerraFirma to help.

    Our System Design Specialist quickly came to evaluate the situation. He recommended installing the VaporLoc Elite Encapsulation System and SuperSump Plus.

    This solution would help remove the pests and keep water out of the crawl space for good!

  • Crawl Space Encapsulation in Issaquah, WA
    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!

    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!

  • Crawl Space Encapsulation in Portland, OR
    Crawl Space Encapsulation in Portland, OR

    With its nearly 7ft ceiling and its wide open spaces, this Portland crawl space was vulnerable to a wide variety of problems, including pest inhabitation and frequent flooding in the winter. After dealing with their crawl space problems for years, the homeowner finally decided to gain peace of mind by calling TerraFirma.

    Our System Design Specialist, Erik Keyes, quickly came to evaluate the situation. He concluded that the crawl space would need VaporLoc Elite, one SmartJack, A TripleSafe Sump Pump, and two MoistureLoc dehumidifiers to prevent future mold. With a plan set, Nick Maszy and his production team came to the home to start the project.

    By the end of the week-long job, TerraFirma installed nearly 4,000 sqft of VaporLoc, removed nearly 4,000 sqft of insulation, and replaced one wooden post that had weakened from constant water damage with a SmartJack.
