Testimonials

I got a bid done by TerraFirma today. After speaking with Seth today. He answered my hundreds of questions and cured and worries I had about foundation issue. He broke it down and explained the whole process from start to finish how to remedy my foundation problems. I like the fact that they were punctual. They were right on time at the scheduled appointment and wasted no time trying to figure out a solution for my problem. The prices He gave to me were really fair and the depth of knowledge was very useful. I feel very confident that TerraFirma should be able to fix my settling / cracked foundation problems.
Thorough assessment, competitive quote, good work crew, and great customer service. Scheduling, permitting, and payment were easy. I had 4 piers installed to stabilize a small workshop attached to my garage.
I reached out to TerraFirma Foundation Systems to have them come look at my foundation. They were able to get me on the schedule within the week. Seth showed up on time for the appointment and got right to business. He walked me through what he was going to do and what he was looking for. He was very professional and polite. He even took his shoes off outside everytime he had to come in the house. Which is a big deal to me. When he finished the inspection we sat down and went over all my options. The whole experience was easy and I didn't feel taken. I would highly recommend Seth and TerraFirma.
Seth came out and did a very thorough evaluation. Recommended how to proceed going forward and was extremely professional. Really looking forward to working with them.
Technician was on time, did an excellent job of explaining the work, quote was accurate, and am very happy with the results.
They went above and beyond to get the project done. They dung out crawl space that you can’t fit into and Did a great job. They treat every thing with respect. Showed up on time and communication well 💯 recommendThanks jorge, jaun,Robert
Seth from Terraferma came to my house on time gave me a fair estimate and recommendations. There was no pressure. He was courteous and I have no hesitation in recommending Seth and his company Terrafirma for any future work.
Fantastic work, great crew of people. They showed up on time, kept me informed of the progress throughout the job, went overboard to keep everything clean. I wish all companies were this professional about their work
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.
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!
