POOR AIR QUALITY

Humidity and condensation in a crawl space are a recipe for disaster. Excess moisture leads to mold growth, wood rot, and foul odors, causing issues for your home’s health, air quality, and value.

After removing any organic materials, making sure your waterproofing system is working correctly, and installing vent covers, you should still consider other airborne hazards that, fortunately, can be prevented with the use of a dehumidifier.

Encapsulation and consistent maintenance don’t just protect against crawl space moisture problems—they also retain a stable temperature in this area, improving indoor air quality and reducing allergens. Over time, this can prevent costly repairs caused by worsening structural problems or degradation. Additionally, a well-encapsulated crawl space boosts your home’s resale value; ultimately, it is a wise investment for homeowners intending to stay or sell. So have Terra Firma fix your crawl space problems today to start reaping the benefits.

From Roseburg to Eugene, Portland to Seattle, our Crawl Space Repair work speaks for itself

We had Tyler from TerraFirma come out to bid fixing a standing water issue in our crawlspace. He was thorough (crawled the entire crawlspace), knowledgeable and responsive to questions. As a real estate agent having access to good contractors is vital, and his professionalism has placed TerraFirma solidly on our short list.
Bailey came out and gave us a quote on some crawlspace waterproofing. He was very knowledgeable, professional, and a pleasure to work with. He was insightful and gave several good recommendations, ultimately putting together a great quote for our work with a couple of different options. I would highly recommend giving these guys a call for your next project.
Mr. Stanford did a thorough inspection of our crawlspace and gave us the honest opinion that very little needed to be addressed. He was very professional and clearly very experienced. This was after a competitor came out and tried to convince us we needed an $18,000 encapsulation.
Jonathan Heredia, Brandon, Jonathan, Lucas and Kameron recently did work on our crawlspace and they did and outstanding job. Very professional! I would highly recommend them and TerraFirma for any crawlspace work.
Andrew, Joey, Caidin, and Preston did the encapsulation of our crawl space. A dingy and damp crawl space has been transformed into the look of a hospital operating room! All were good workers and very helpful, with ideas and tips, and noticed issues that were not a part of their duties, but nonetheless did need to be addressed. No review yet on how the system works, but I can highly recommend this installation crew! Thank you guys!
Just had clean out of old duct work and old insulation, etc. plus encapsulation of my crawl space. The crew worked really hard and professionally throughout the 5 day process and the foreman kept me informed along the wife. Have worked with Terra Firma on several occasions: pier placement and jacks for house, french drain in crawl space, and replacement of sump pump, etc - alll involved from the estimators, the office personnel, and work crews have
been excellent throughout.
We had concerns about the foundation and flooring of the home due to water and moisture in the crawl space. Walt, out of the Roseburg office was very responsive and timely with accurate information for our situation. Ultimately, we decided on crawl space encapsulation. The bid was easy to read and laid out a comprehensive work plan for our home. They were also able to meet our scheduling needs for the timeline of our project.
These folks are WORTH the call and having them out! Seth, specifically, was amazing at scope, plan and presentation. He was so knowledge and really took into account all of the needs of the house structurally and visually. He was extremely professional in house and on the phone. Nothing was over sold or up sold, and every concern I had was listened to and taken into account. Every detail was in the bid neatly and nothing was out of place. If you've got a basement or crawlspace project, this is as professional as it gets. I will DEFINITELY be keeping this company in mind for future projects and for friends and family. Call. Ask for Seth. He's got you.
I was referred to John from Terra Firma when I was looking to have our foundation inspected. John was very friendly and knowledgable and came out to our house to measure and inspect everything. In the end he was able to put our mind at ease and did a great job of explaining different scenarios and what he was looking for.

John even inspected the crawlspace while he was out and provided great feedback there as well. Overall we got a lot of good information and never felt as though we were being pushed into unnecessary services.

I will certainly be reaching out to Terra Firma for any future needs!
Jorge and his team did a great job in my crawlspace replacing 40-year-old cracked wood support posts with TerraFirma's SmarkJack posts. Jorge was kind, respectful, knowledgeable and thorough, always keeping me informed as to exactly what he and his team were doing and how long it would take, plus having me check on their work. Thank you for the excellent service.
