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

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.
Quinten, the service technician, did an amazing job of servicing the pumps and the dehumidifier, he thoroughly inspected the encapsulation system as well.
He is very knowledgeable about the whole system and answered my questions.
He gave some options for 'shipshape' warning system as well as 'Aspen Air 'purifier' both of which I intend to move forward with.
Your company is fortunate to have hired this quality of personnel.
I am equally satisfied with the original encapsulation crew.
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.
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.
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.
Walt B. went above and beyond for us. We had some concerns about heavy furniture over our crawlspace that he took the time to analyze and talk through with me. As homeowners without a ton of experience under our belt, we were thankful for his time. Walt walked me through our concerns, assuaged our fears, and even gave us some helpful tips and pointers on add'l home maintenance. I also appreciate that he was honest and open with us: he didn't upsell us solutions, didn't suggest solutions we didn't actually need. It was a great experience.
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.
Jaden Torson advised me on the best solution for my crawlspace. He was willing to work on picking up and correcting the poor work a previous company had left. He understood the need for a correct, clean space in order for a kitchen rehab to happen.
The company made great efforts to arrange schedules so my work could happen in an efficient, timely manner. All staff were very pleasant and professional. They did exactly what was promised and I highly recommend them. It is so relieving to have someone like Jaden who is trustworthy, practical and honest. I’m very pleased!
I had a fantastic experience with TerraFirma Foundation Systems this week. Jorge and Juan were absolutely outstanding to work with—punctual, professional, and always had a smile on their faces. Over the three-day job, they worked tirelessly, digging trenches, transporting river rock, and installing the sump pump with great attention to detail. They took the time to explain every step of the process, which I really appreciated. The crawlspace looked excellent when they finished, and they cleaned up everything—no debris left behind. I’ll definitely be requesting Jorge and Juan again for any future work. Highly recommend!
Travis and his crew were absolutely outstanding. They were very friendly, clean and neat during the process. They informed us of a leak that we had no idea about. Saving us costly damage, we truly appreciate it.
I had to go in the crawlspace since they completed the job. Absolutely amazing! Prior to them completing the job, whenever I had to go under, I was 50% sure something was going to jump out and kill me. Now, I feel I can easily camp out there with confidence.
Thanks guys, Amazing!! Money well spent.
Wish you all the best, for all your hard work.
