4.6/5
John S. SW Sunset Drive

The Terra Firma crew from start to finish was amazing. Josh really did a great job explaining every step of the project and answering my questions as we went along. The Foreman Leo and his crew, it was like they were never there. You wouldn't have noticed my house has been touched nor lifted 3 inches. My overall experience with Terra Firma was excellent and I recommend them, especially these two and their crew for any home repair work applicable.

Ken O. NW Hayes Ave

I was very impressed with the care taken by Jeremy L Schwab and his team of Kyle and Martin. They had unusual challenges removing the deck which was fastened from underneath the boards. Jeremy let me know what was going on and we made decisions together where compromise was necessary. Same with the actual lifting of the house - I was directly involved in reaching the right tradeoffs for how much to lift the foundation. The cleanup was thorough and extra care was taken to do the job right.
