Secure Your Crawl Space with TerraFirma

Crawl Space Encapsulation Contractor in Portland, Vancouver & Nearby

Give TerraFirma a call and schedule a free crawl space 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 crawl space is tiny or large, we can make it a clean and 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
    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 Pleasant Hill, OR
    Crawl Space Encapsulation in Pleasant Hill, OR

    The homeowner in Pleasant Hill, Oregon, was concerned with water and humidity in their crawl space. To fix the issue, they reached out to TerraFirma for help. 

    Our System Design Specialist came out to the home and found that the crawl space had standing water inside and didn’t have a vapor barrier or vents, only a fan that runs and pulls air from one side and exhausts out the other. He recommended the VaporLoc Elite Encapsulation System, SuperSump Plus, Aprilaire Dehumidifier, Vent Covers, and Drainage Matting to clean and dry the crawl space. 

    With a plan in place, TerraFirma had installed all products within three days!

    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.

  • 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!
