Service Area

Great to work with, very responsive and professional. I appreciated how quickly they fit us in so our home sale could close on time.

I had two estimates. TerraFirma was much cheaper but more than that they moved fast, were clean, professional. The inspector gave them high marks and I have a house that is earthquake secure to magnitude 8 give ir take.

Great work done. The crew arrived on time. They explained what was going to happen with the job. On time and it looks great.

Very professional and thorough. Failed to clean up after the job our only concern. We had to have a cleaning service come. Terra Firma paid for it.

Working with Walt is always a win. He has an incredible depth of knowledge when it comes to this industry but what really sets him apart is how well he communicates that knowledge to clients. He takes the time to break down complicated issues in a way that actually makes sense—no fluff, just straight-up useful info. My clients felt informed and confident thanks to him, and that’s invaluable. Highly recommend!

Zack, Andrew and Joey showed up every day by 8:30, worked their butts off & always left a clean work site... totally 5 stars for these guys. There was a 4th workerbee, but I never got his name & he was great too!

Our basement waterproofing job was completed on schedule the crew was professional and easy to work with. When we have other foundation or concrete work to be done TerraFirma will be our first choice. Jonah was a good coordinator and everything went smoothly,

Alex and his team were great on time and got the work done in the alloted time

***Please note -- I updated my review from 1 to 5 stars. Terra Firma took the initiative to reach out 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.

Everyone, from the job estimator and office staff to that guys that repaired my foundation/driveway and installed the earthquake mitigation system, were very professional and courteous. Very happy with the final result!

We had our annual maintenance of our system, which was installed 2 years ago. Stevo was friendly, respectful and professional. He performed detailed maintenance, provided reasonable suggestions for future care, and made sure we completely understood everything. Highly recommend!

Marcus was here today doing the annual inspection. Best inspection we’ve had. Best inspector we’ve had, although all of them are good people. Fixed what was needed, cleaned filter on dehumidifier and cleaned sump pump. This gives us a secure feeling that everything is right. Thanks Marcus.
