    Inspection was very professional and more complete than the other two companies we used for quotes. Measurements were made and plans drawn out on their quote. (One other company barely crawled into the space and took no measurements.) Groundworks was not the cheapest quote but you get what you pay for! Quality install, done quickly, all questions answered. Installers Tripp, Keegan, James and Ryder worked well together, were polite, and got it completed quickly.

    They are a good Geologist/ civil engineering firm. I was happy with their evaluation of the subsurface for my foundation.

    Ernest was great at inspecting my issue. I learned a lot and felt like he really listened to me and gave things a thorough look.

    A neighbor of ours had used Matvey for some foundation work on their house, and they recommended them to us.

    ***Please note -- I updated my review from 1 to 5 stars. Terra Firma took the initiative to reach…read moreout and assess any next steps needed to correct the problem. Trust is 100% restored knowing that if problems come up they will take any action needed to follow up. I will also say that the work they originally did was actually to code, and we agreed that the moisture problems arose due to the nonstandard setup of my dehumidifier, NOT because of errors in Terra Firma's work. Thank you Terra Firma.*** Unfortunately, I have to drop a negative review in the interest of warning other folks that their work has gone downhill. I previously had an excellent experience with Terra Firma for management of a water problem in my crawlspace. I hired them without question again for my current property for management of moisture issues, and I didn't check their work upon completion as thoroughly as I should have. Unfortunately, about 1 - 2 months after completion of work, I discovered a large mushroom growing out of one of the structural posts in my crawl/basement. On closer inspection, I noticed that the dehumidifier water discharge line they installed was dumping less than a foot away from my foundation, corresponding to the exact spot the mushroom was growing. Moisture was the exact problem they were supposed to fix, but now they have created a severe structural problem secondary to moisture with the dehumidifier line dumping large quantities of water right next to my foundation. In other words, they created the exact issue they were purporting to fix by collecting the moisture and depositing it into my foundation. Once fruiting bodies are growing out of wood, this is an indicator that the wood is severely compromised and the fungus network has grown extensively. I now have a very expensive and serious problem to fix. I called to let them know about the problem, not sure if I will hear back from the coordinator/ the team who did the work. I am not sure if I would trust them to fix the issue after the damage they have caused, but I would accept financial remediation. If they take steps to make things right, I would update my review. I would not hire Terra Firma again for any crawlspace work, be it structural or moisture related because of the big problem they have caused. Again, just would like to warn others.

    Hired to correct sinking floor throughout the home, to the point doors couldn't close or would…read morestick and could feel significant change in the floor height while walking. TerraFirma sent over an estimator, then scheduled repairs. They were done in less than one working day and provided photos. They laid down paper to protect the floor as they were working. Due to another issue found, had to reschedule a second day to come out and install a supporting beam in the crawlspace. Different crew but were as professional and clean as the first. Folks in the office were helpful and responded quickly. Would hire again if needed.
