1. Foundation pier support - appears to be good work. 2. Earthquake retrofit - less than perfect on cutting into living spaces to attach hardware -...
Very pleased with the work, from the beginning sales person visit to the ending follow-up chats, on the phone, about the work performed. We had a foundation...
I’ve always heard Terra Firma could repair sagging concrete on porches and they do. I couldn’t be happier with the results. Jonah our project manager was informative and although I might not like today’s prices it was less expensive than building a new deck. Ken and Dorian showed up on time, very professional, did a great job. After talking with Ken you could tell he had a lot of experience and it showed. I would Highly recommend using Terra Firma.
Living in a 30-year-old home for the past two decades we've had several phases of upgrades, but one thing has always been absent from a 10x10 slab on our...
From free estimate to job completion, Terra Firma was a great, reliable company to work with. The no pressure estimate allowed us time to decide if / when we wanted our job done . After we decided to hire them the crew was fast, efficient and clean! They had photos of the completed job before and after (as I chose not to climb into the crawl space )and it looked stable, clean, and brand new! Very happy with Terra Firma and a job well done!
I got a bid done by TerraFirma today. After speaking with Seth today. He answered my hundreds of questions and cured and worries I had about foundation issue. He broke it down and explained the whole process from start to finish how to remedy my foundation problems. I like the fact that they were punctual. They were right on time at the scheduled appointment and wasted no time trying to figure out a solution for my problem. The prices He gave to me were really fair and the depth of knowledge was very useful. I feel very confident that TerraFirma should be able to fix my settling / cracked foundation problems.
Technician was on time, did an excellent job of explaining the work, quote was accurate, and am very happy with the results.
They worked together very well. Polite to me. Answered my questions has they were working. Cleaned up their "mess".
I’ve had a great experience with TerraFirma so far. Seth Cunningham is the tech that we have been working with, he has thoroughly explained the issues we are facing with our foundation and the steps we need to take to salvage our home. Although this is a blow to any homeowner, I trust that Terra Firma is going to get us back to where we need to be step by step. Communication has been top notch, and I feel confident we are in good hands…… update!!! The work was completed by the crew, they were so professional and nice. Got the job done and were even able to eliminate one of the jobs because they were able to make it work and they made me aware of a leaking pipe under the house I didn’t even know was there. Invaluable!!! This is a very good company to work with, I really am satisfied.
Work was done professionally, quality technicians.My complaint is with modifications that were made that should have reduced the labor, materials cost but no consideration was given for that.Full payment no negotiation.The amount of prep work that had to be done, the rebuilding that will be needed, the lack of resources to complete these tasks…I’m happy with the product, not so much the experience.
