TerraFirma Foundation Systems is excellent at basement waterproofing. Be sure to ask about all the available options so you can choose the one that’s right for you. The company is very capable, but it’s important to do your research before making a decision. The crew—Antonio, Jessi, and Casey—worked extremely well together. Antonio is especially sharp; whenever I suggested an idea, he immediately understood what I meant and offered an even better solution on the spot.

The crew that came out from Terra Firma Foundations was amazing. Explained everything so clearly that a dummy like me understood what they were they were doing. Answered all my questions. Cleaned up the work-site so it was cleaner than when they started and did an all-around bang-up job. In case you're interested in requesting the crew I had, the team was: (Timothy Cranley II, Jonathan Heredia, Jairo Torres, Rodolfo Ruiz, and Zack Etters.)

We had an excellent experience with TF earlier this summer. Morgan spent many hours at our house evaluating our foundation, clearly explaining our options, and checking up on the crew once work commenced. Foreman Luis and his team (Tony M & Gustavo) were professional and efficient, and kept things on track. Thanks also to Heather for coordinating the whole operation. We are pleased with the outcome and look forward to a dry basement!

The crew did a great job fixing our sinking foundation! Two days and they came in and dug everything up then set the anchors and then backfilled! Great Job!

We had TerraFirma out to work on our foundation six months ago and were very pleased with the experience. We had a pretty big project on a home built in 1900 and the company worked with us to divide it into phases so it wasn't so financially overwhelming. Phase 1 included crawl space encapsulation, replacing old wood columns with smart jacks, carbon fiber stitching cracks, installing a dehumidifier and a sump pump with drainage line. After starting the work they realized some components that had been in the contract weren't needed and they quickly had me sign an addendum that would lower the cost of the project. James Taylor, the lead was great to work with, always explaining their plans for the day, progress they had made and ensuring that we were pleased with the work. The crew was right on time every day for two weeks. They were clean and courteous. They were set to finish a day early but found some water entering the basement while they were wrapping up. James called his supervisor and they set to work installing a section of drainage system that was unplanned. They did this at no additional cost because they said that is what they were hired to do and it was the right thing to do. I was shocked by this because it is hard to find a company and crew off workers that will stand by their work like that. Terra Firma might be more expensive than other quotes you get but it was the first time I have felt that a company genuinely cared about the quality of their work and they treated my home with respect. James and his crew (Byron, Alex, and Jake) went way above and beyond to make our basement a better and more useable place. They certainly could have just done the minimum that was agreed upon but they didn't and they will get my business for any future needs because of it. Our unfinished basement and crawlspace is now clean, comfortable and dry. The work was transformative. I highly recommend this company.

I hired TerraFirma to encapsulate my basement and crawlspace because my house is on a. slight slope and the rainy PNW winter was causing all sorts of humidity issues. Don was dispatched to my residence and was very professional in explaining all the options available and helped me select the best option for my situation. Scheduling was a breeze and the crew that did the installation was very competent. I worked with Timothy, Chris, Train, and Jairo and they were magnificent. There were some hiccups along the way, but the team took care of every minor bump and made me feel valued as a customer. There was very minor interruption to my life and the basement/crawlspace is even cleaner than it was before! On top of everything else, I believe the price was very fair for the work that was done. If I ever have any foundation/basement work to me done again, I will definitely reach out to TerraFirma!

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!

Tanner Heinz assisted us with our foundation concerns in Port Orchard. I was really impressed with his professionalism & his kind & patient demeanor. As a Realtor, I meet many different types of contractors. It was nice to see a person who looked, dressed and smelled good! He explained his process, what he observed and answered the clients questions. From appointment to estimate was handled 1st class. Smooth, swift, friendly with competence. I’ve used them personally 5years ago for my sinking deck and my service then was just as great as it was now. I will refer your company to my clients snd friends. Thank you Kristin Rubatino

Terra Firma recently completed a foundation lift involving 18 push piers and 3 helical. My home is situated on the Columbia River with a sloping hillside down to the river. I couldn’t be more pleased with the end result, all completed as proposed in the original estimate and time frame! The installation crew dispatched out of the Vancouver Washington branch, James Ragsdale, Roberto Burgos and Antonia know the business and were a pleasure to work with. Bruce McPeak

Last winter we noticed some standing water under the house. Not serious or due to some foundation issues, just significant groundwater saturation. At the time, the sales person spent a few hours mapping out some options for us. Last week we moved ahead with the inside foundation drains and sump pump. The team were on time, the project manager was helpful in walking me through all the steps and they worked hard to mitigate any dust issues. This stuff is never going to be inexpensive, but they did what they said they were going to do and left the inside of our house like they found it. Bring on the rain... Thanks Terrafirma.

Brian Comunale was incredibly thorough in his inspection and assessment of my compromised foundation. He took pictures of all the damage and explained the issues and possible solutions. He went above and beyond. Truly phenomenal communication and customer service. I highly recommend his services.

Terra Firma installed tiers on the side of my home that showed Early evidence of Unstable foundation. It wasn’t cheap but with a 75 year guarantee I am confident it was the best repair.
