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.

The deliveries of stone went very smoothly, and the stones themselves are really terrific (see photo). Building a wall with these is admittedly a lot of work -- they are 65lb each, so we were pretty tired -- but they are worth it in the end. The stones are definitely a step above what you will find in big box stores. There are helpful videos on YT and on the Mutual Materials website about how to install a proper foundation for your wall with 4-6" of crushed rock compacted and leveled underneath, as well as a good drain system behind it (otherwise even a short wall will buckle and sink due to inadequate compaction underneath and hydrostatic pressure and freeze/thaw cycles pushing it up and out).
