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.

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.

Two months later they came back and changed out 3 grated clean out covers with ones that have filtering screening on them to address insects hatching out of the clean outs.

There was some excessive damage to my lawn in the process and credit to Jerry for offering to make it right and following through. After following all care instructions provided, which were very few and required my own research, my family and I left town for about 6 weeks leaving the patio to continue curing to its final state. Upon our return not even 3 months later we returned to a patio with cracks throughout it. Pacific Coast Concrete has taken zero responsibility for this, calling it a natural outcome of the shrinkage of the slab but I have this new one next to a 20 year old slab that has exactly zero cracks in it. From what I have read and been told by other concrete professionals, shrinkage cracking can be normal, but is usually caused by inferior materials or preparation of the concrete itself (too wet, etc.). It is a shame that Pacific Coast Concrete will take zero responsibility over the condition of the slab they poured just 3 months ago.
