Seth came out and was very professional and personable. He did a great job sharing your product with us. We could tell he was knowledgeable about your product. We also could tell he enjoyed his job.

From making an appointment till the end of the project, we were well informed. I was a little concerned about the drilling holes on the concrete to fill the void but they are almost invisible.

As a residential broker in western WA I’m always interacting with different foundation & basement specialists. TerraFirma is the best I’ve come across. The team there, especially Seth, is top notch. I always get an accurate & reasonable solution from them regardless of the size of the job. I’m working with Seth on a project now & it’s been great. Highly recommend!

TerraFirma was great to work with. The office staff kept me informed of any changes in the work date, and the onsite work crew was respectful and kept me informed of the progress on the project. The work crew cleaned up the worksite when needed and were very kind and respectful. I am happy with the finished project. Thank you to all at TerraFirma! I would highly recommend them.

Robert Carmona and his team were professional, thorough, and pleasant to work with. They did an excellent job leak proofing our basement - we're thrilled with the result! They also left the place better than they found it. I so appreciate their hard work. Thank you Robert et al!

Excellent work on transforming crawl space. The experience with Terra Firma was outstanding from our first meeting with the technical specialist Andrew Fry through the completion of the project. The work crew was courteous and professional and did a fine job. Thank you Terra Firma!

My 50 yr old house was beginning to slide down and sideways off the hill. Terra Firma fixed it! The warranty is for 75 years, and goes with the house, so future owners are protected. Professional hard working people. Recommend them 100%.

The company did good work. This is the second time we have used these services. Price has almost doubled in five years. Getting expensive!

Pat was so good not only at his job, but is an extremely personable type of communicator, is polite and most of all knowledgeable. I’d say he is going places with this company! It is hard to find adequate people these days, let alone someone who is capable of carrying on an educated and informed conversation while listening to my questions and concerns , then actually (past 5 pm on over-time) taking the time to explain them. He was patient and kind to both me and my young daughter. I appreciated his honesty about working with connected buildings, even if it risked new business for his company. If he isn’t already a manager, he soon will be! If you call Terra Firma i’d suggest asking for Par and if Pat works for you, I’d suggest a raise next review!! lol
