5.0/5
Bill & Gail B.

You employee started cleaning under our house for the new foundation last Tuesday. My husband Bill and I were very surprised at how difficult the digging turned out to be. This house was built in 1947, on the site of an old hotel that burned down in 1945. Apparently the fire caused the Earth to be baked into brick-like hardness. And also everything buried on site. What a terrible excavation job!

Your men are very hard workers. They are very hard and determined workers. We are very glad we hired your firm to do this job.

Sincerely Gail

Robert G. Oak Street

I am a ex contractor myself; regardless this situation was very new to me. I felt the crew leader was very experienced in determining placement of pillars and what to do with changes on the ground. I still will have to see how the house reacts next summer before the 4's can turn to 5's on the survey. I am less stressed from worrying about my house settling and can move on with other home improvements. Though this is not a cheap fix, the material that was used to support and stabilize the foundation was top grade steel. That is what impressed me. The quality of the support structures used. I will and have recommended Terra Firma in my area.
