I am so glad I called terra firma John did a wonderful job lifting my concrete and went above and beyond my expectations and if there are any issues with the work I can call terra firma Customer- Alex (Auburn)

Since the pandemic, my experiences with contractors has been mediocre at best. They cost more and do not do as good of a job. Generally they send poorly trained or overly busy employees . So it was very refreshing to have Schylar P. with TerraFirma come out and do such great work. Imagine having a contractor show up on time, being knowledgeable, and doing the work as promised in the timeframe given.

This company is the gold standard for those interested in maintaining the health of their home. I tell you, ‘My home will never be the same’: The garage is level; We are earthquake proof; And, the will no longer be mold or mildew in my crawl space. The best part was, not just the satisfying outcome of the work done, but meeting & working with Walter. He talked to me so that I understood why parts of my home were on a downhill slope to disrepair. He drew illustrations so I could visualize each point he made: He was upfront & honest in his assessment of my 1972 home built in clay. If Terra Firma is the gold standard- Walter sure is the diamond. Get your free evaluation today & don’t forget to ask for Walt.

Stevo Clay did a great job for us! So helpful and very polite.

We had a bedroom floor slab that sank many years ago. We never knew what could be done to bring it back level. After seeing you guys work and bring it back to level, I was completely amazed and very satisfied. I would absolutely use Terra Firma again.

From start to finish it was a fantastic experience and we feel our house is safe now.

Wow. Hiring TerraFirma is hands down the best decision I made in 2024. The team I worked with at TerraFirma is world class and able to take on hard technical challenges, tight timelines, and financial constraints - and DELIVER. I trust them with the wellbeing of my kids. They saved my house (literally!) My 100 year old house is funky and scares away 4 out of 5 contractors who will decline to bid b/c of technical challenges alone. In this case, I also had tight timelines and budget requirements that made this job just about the hardest I've heard of for a contractor to take on by 10x - and terrafirma pulled it off! Pulling this feat off was only possible by incredible team work within the company: The install teams by Nate and Rocky were amazing and were able to spot issues and route them to engineering on the ground, Sammy and her coordination team kept me in excellent communication, and Morgan was able to come up with options that would work for my constraints, requiring creativity to pull it all together. I was impressed with how EVERY single person in this company was empowered to make decisions and judgment calls - and at each point chose to work together to find solutions. It's easy for individuals on a team to say no - far far far harder to problem solve to say yes. Thank you TerraFirma.

Great experience. Gave a a thorough walk-through of all work with free estimate for several projects. Followed through with exactly what I asked for.

Great customer service!

excellent customer services, excellent communication and services, the Best in the northwest

I hired TerraFirma to put an interior drain and sump pump in my Seattle basement after some flooding. When they pulled up the carpet to start work it became obvious that the problem was much bigger (roots running all through and cracking the foundation). The plan had to change entirely and the job got way bigger. Luckily, TerraFirma was with me the whole way. They owned the problem from end to end, figuring out how to get the new work done within a reasonable price and coordinating all of the various sub-contractors who were involved in removing and repouring my basement foundation. Ryan and his crew were always extremely polite, hard working, communicative and timely. It's not an experience I would ever want to go through again, but if I did, there isn't anyone else I would call.

On time, thorough
