Testimonials

Bailey did a fantastic job inspecting my crawl space and designing a solution that fit my needs. I really appreciated his thorough evaluation, detailed explanations, and professionalism. I will keep TerraFirma in mind for future projects.
We hired TerraFirma to fix our foundation. They inspected thoroughly, explained the plan, and completed the repairs professionally. The process was smooth, and we’re thrilled with the results. Highly recommend TerraFirma!
We had an excellent installation on a fantastic crawl space waterproofing job. We are on the northern Oregon coast and a few feet from the sand so we get a lot of moisture under our 1940s home. We decided to invest in the TerraFirma product after a great meeting last summer with Don as we were taking on a major house renovation and decided we would do what is best all at once. We are very happy we did as the product is a game changer for the health of our home and our next generation. We pick up some great additional waterproofed storage space too in the end.

The install process was efficient, and we had three outstanding guys working our job. Antonio, Jesse and Cameron deserve a big shout out. They spent time each day we dropped by to educate us on what they did that day, show us every aspect of the job and took great care to be hospital-like clean. Sometimes not-so -ice people do very good work, and sometimes really nice people do shabby work but in our case with TerraFirma, we received an excellent service from very nice guys. So glad we found Terra Firma!
I had an excellent experience with Seth from TerraFirma during the field review of my home. He was punctual, professional, and extremely knowledgeable about every aspect of the house. Seth took the time to explain what he was seeing, answered all of my questions clearly, and made sure I fully understood the condition and next steps.

It’s rare to find someone who combines expertise with genuine care and attention to detail, but Seth absolutely delivered. His professionalism and confidence gave me real peace of mind. I highly recommend Seth and TerraFirma to anyone needing a thorough and trustworthy home field review.
Job was on time, on budget, explained completely at each step and the crew (Jose H, Matt A, Ivan, Steven and Manuel) were meticulously clean through each day and cleaning up at the end of the week. Great experience overall, highly recommend.

Phillipe oversaw the crew- he was tremendous! Thanks all!
Jaden was prompt, professional and courteous. I would recommend him to anyone who requires his services.
Andrew, Zach, and Brent arrived and completed the job on time. They worked with our old house’s existing flooring.

Unfortunately this sump pump did not solve the problem after all, as water again came in after several days of hard rain. To be fair, TF did not guarantee a solution. I still think it is a good company but sadly my problem persists.

Previous review from Nov 25 -

Terra Firma installed a sump pump in my home that has solved my water incursion issues. This had been a problem for months. I had several different companies and professionals out to evaluate and try to solve the problem, from plumbers to leak detection companies and a few more. Most scratched their heads and said "this is a mystery." Terra Firma came up with this solution and it is working. I wanted to wait until we had significant rain to write this review - and after the past few days of pretty good rain, and no water coming in - I feel confident that the problem was solved. They were helpful, considerate and creative. They didn't try to sell me more than was needed. I recommend Terra Firma.
We had some basement flooding in our house and after learning the cause, we started the work of getting quotes and inspections from Foundation specialists. When we called TerraFirma, Bailey was able to make time for our inspection within the week. From the jump, Bailey was very communicative, and set expectations upfront. He asked what was going on, looked at some suspected intrusion points and then let me know he'd carry on with the inspection and would let me know when he was ready for me. No awkward standing around or wondering how long it would take. Bailey was very thorough with his inspection and had an impressive presentation once he'd made a diagnosis. He told me his ideas and then asked me mine and we both felt good about the plan walking away from it. Ultimately our timeline didn't work out and we personally had to go a different direction, but if it did I'm confident we'd be in good hands with Bailey and TerraFirma!
I had Bailey come out to do an estimate for crawlspace encapsulation and some drainage work in the basement. Bailey spent 2 hours at the house and on the phone with me in total (not counting the work he did on his own), doing a very thorough work up of the house and patiently explaining what my options were, and what might be better for my renovation contractor to do. I really appreciated Bailey's willingness to think through different options - some that didn't include work for his company - and teach me about crawlspaces!
