Julie Fox

As a Realtor, Firm Foundation is by far my #1 foundation company choice. Working with them is always an excellent experience. Ryan Green was HONEST, professional, responsive, and clearly takes pride in his work. He communicated well, paid attention to details, and made the entire process smooth and stress-free. The quality of the final result was outstanding. I’d highly recommend them to anyone looking for reliable, top-notch work.

Nowadays, it is very difficult to find trustworthy and reliable companies for any type of repair work. We hired Mason Birdwell owner of Firm Foundation Repair to fix the settling foundation of our home, and we were truly impressed with the quality of their work, the fair pricing, their attention to our needs, and the timely completion of the project. Mason has built a team of true professionals. They were knowledgeable, efficient, and respectful throughout the entire process. We are very grateful for their excellent service and would highly recommend them to anyone in need of foundation repair.

Ryan Green and his firm, Firm Foundation, did an outstanding job of repairing the foundation of our home. One day, we noticed some major cracks in our den and kitchen ceilings. We realized that we had to check into our foundation. We obtained the quotes from three separate foundation companies. Firm Foundation was one of them. The other two companies gave us quotes to install piers around the perimeter of the entire house, including some interior piers that would have meant digging up some of the flooring inside the home. We received a quote from Firm Foundation who recommended that we install piers around only part of the home. Because there was such a discrepancy between the quote from Firm Foundation and the other two companies, we had a structural engineer come out and give us his independent analysis. He confirmed that the work recommended by Firm Foundation was all that was needed. Going with Firm Foundation saved us thousands of dollars. We are very, very happy with the work they did. After they were completed, we had our structural engineer come out again, and he confirmed that they did an excellent job. We wholeheartedly recommend Firm Foundation to anybody who needs foundation work done on their home.

Great company. Ryan was very fair and straightforward in the estimate. The crew worked hard and were very professional. They found a hole in a sprinkler pipe that they didn’t cause but fixed it anyways since they were already there digging around it. They communicated every step with my wife and I. All around a good experience and would definitely recommend them again.

I highly recommend Ryan and his team. I struggled for several weeks finding a company that was responsive, transparent, and skiiled to take on this project. Fortunately, a freind recommended I send the project to foundation repair companies. Ryan replied to my request immediately, and he met me at my house shortly after our first conversation. We met a few times before committing. He was early for every meeting and showed honesty and patience from start to finish. The retaining wall and swale look great, and our drainage issues are completely gone. I was so impressed by his company. They far exceeded my expectations!
