Being my first home, I went into it knowing my foundation would need extra care. The TerraFirma team was amazing and very personable. I mean everyone to included, customer service when you call for an appointment, to the initial inspection, and Shea calling to make the appointment. I had Collin as the lead for my home and, he made it happen. Couldn't have had a better group be so professional and kind. Makes all the difference. Glad I was able to find these guys. Highly recommend. 🎉🎉🎉

We purchased a home in 2020 that had undisclosed water infiltration in the basement that resulted in all basement finishes needing to be demolished to clean up the water and remove mold. TerrFirma was the only company who was able to diagnose and address both water infiltration caused by poor exterior yard grading and drainage and also the interior water proofing needed. They also repaired and stabilized a very large structural crack in our basement foundation wall. In addition to doing all this work they were also able to fit earthquake retrofitting into the project while here when asked (after they showed up to start the project). The estimator, Bridget was very meticulous in her bid and made comparing estimates easy. Her experitse, flexibility, follow through and communication were superb. Working with Spencer Hunt, the project foreman, was so stress free. He was able to accommodate our request for earthquake retrofitting even though TerraFirma was extremely busy. He was excellent at explaining everything the crew was doing. He checked in with us through every step of the process to make sure we were educated about and happy with the work. We are so happy we used TerraFirma and would recommend them to anyone who needs drainage, foundation, concrete, earthquake and waterproofing work done in the future!

TerraFirma responded quickly to our call. Came out the same day for a free evaluation of our foundation in old town. Samuel was very friendly, professional, and obviously well knowledgeable about his trade. Within 2 hours we had a very thorough assessment of our foundation, including historical knowledge of our home that I didn't even know about. Thank you TerraFirma, and Sam, for helping us through this!!

In a word, Terra Firma was AWESOME! From the beginning to the end. Everyone involved, from the first visit by Tyler to the project coordinator, Jonah, to the crew that did the hard work of stabilizing my foundation, James the foreman, along with Oscar and Jayden. The engineering and permitting with the city were handled and I was informed all along the way. The crew showed up on the dot every day, was friendly, professional and respectful of the property. My property was restored to the condition they found it in with pressure washing and putting the deck back together. They also alerted me to problems with my plumbing that needed to be addressed that I would not have otherwise been aware of. It was work that needed to be done to avoid any further damage, inability to sell at a later time or saving my family the burden of dealing with it.

Excellent collaboration with the design, project management, and the work crew on foundation repair. Good, understandable, information provided and satisfactory responses to our concerns. Costs were within our budget. Had to have the crawlspace cleaned-up first before work could be done on the foundation. Highly recommended company to work with.

We have had thoroughly excellent service from TerraFirma since October, 2017, for a variety of issues involving flooding and foundations. TerraFirma seems to us completely competent and reliable. We would recommend this company to one and all.

We had a foundation issue with our home and contacted TerraFirma Foundation for help in resolving this problem. The work was outstanding, the service great and prompt. Sammy, Geovani, Diego and the rest of the team that we interacted with were all professionals and we are very happy with the work done by all the members of the teams that worked on our project. Thank you.

Luis and crew were great to work with. Excellent communication, respectful and courteous workers. Thoroughly explained and maintained a workplace with care. Really worked out to be a better experience than expected. I was initially nervous about getting into this work. Brandon who was the initial person that surveyed and estimated work to be done was always available for explaining and answering questions clearly. Materials used of top quality, cleaned up at the end of each work day. Highly recommended. Tara in office helpful from her end as well.

When we first bought our 1900s fixer upper, we had no idea what lurked behind the walls of the illegal basement apartment. Once we opened up the space we were in for quite the surprise. All the wooden post holding up the main beam of the house were rotted through at the base. You could stick a pencil through the old, soft wood. Working with TerraFirma to fix the issue was an easy choice. Eric came out to assess our problem. He was friendly and professional as he walked me through the process that was needed to fix our foundation. It wasn't going to be cheap. Don't expect this kind of work to be inexpensive (especially on older homes). We needed concrete to be cut, 2ft cubic footers poured, and six shiny new steel posts. (And while they were coming out anyway, we had them do seismic retrofitting too). There's all kinds of math and engineering that goes into determining what's needed to structurally support a home. TerraFirma handles it all. And they are experienced enough to know what it's going to cost. One of the best parts of working with them (besides the friendly employees and professional workers) is that the price they quote you is going to be the price. Full stop. There are no unexpected add ons at the end. I can sleep well at night knowing TerraFirma's work is holding up our home. A few months later when the rains started in earnest and our basement flooded (an issue we guessed had been going on for a while, hidden by those illegal apartment walls and leading to the rotting of the old wood posts) we knew who to call. Eric came out again to look at options for a sump pump system and even worked on adjusting those plans (while he was on winter vacation with his family!!) when we discovered that a third wall was seeping water and we needed a much larger amount of fixing than originally thought. We no longer have to worry during downpours. While our old fixer upper still needs a lot of work and love, we know that we are (literally) starting from a strong, solid foundation thanks to TerraFirma.

TerraFirma raised a corner of our house foundation that had settled due to soil failure. They did a fantastic job working around gas and water lines and when they were done you could not even tell any work had been done. I would definitely recommend them .

While it's an expensive job to rehab your foundation, most of this crew was super supportive and explained things well. They did a great job, even with a few hiccups which they recovered gracefully from. Well done and thank you!
