From the planning and estimate to the final finished work, competence and courtesy were the norm. Rescheduling when there were delays was somewhat lengthy

Awesome job fixing the tripping hazard that was my sidewalk. From friendly and professional Pat who came out to assess and provide an estimate; to Amber, the project manager who was communicative, helpful and friendly; to Johnny who actually did the work I'm very pleased with - Thank you! Would highly recommend!

Superb service! Excellent work. We asked them to lift (if possible), support and seal our driveway to stop some puddling, along with placing a new walkway to our front door. The concrete work was very nice, beyond complaint. The driveway was a question mark to start with, but they did well. Upon leaving, they invited us to call if we needed more adjustment. We did, and found them to be immediately responsive and very pleasant. Upon leaving again, they repeated their invitation to call again. All personel overall were very pleasant and responsive. (I am not financially or personally affiliated with Terra Firma in any way!)

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.

Had TerraFirma come to our home for estimate to level our drive way, which had been "leveled" 2x prior and failed, Turns out, in less than 1.5 yrs, our home fell forward 1.78 inches and cracked our foundation in 3 places... YIKES! The work got underway once permits came in, the 2 crews did an install of 4 piers indide our garage and leveled a driveway, walkway and entry steps.
Hands Down, we are beyond words Beyond expectations happy with our now Safe home!! If you need any of the services TerraFirma provides, hit me up... I will fill you in on how professional, respectful and knowledgeable their crews and staff are! In all 5 Star ratings, we wish we could give a 10+

The guys were fantastic. Any requests I made were immediately address in the most professional manner. I love my house now. Neither my husband nor myself have had respiratory issues like before we had Terra Firma seal our foundation and add the dehumidifier. The best part is that I don’t have to empty the dehumidifier and my house is dry now. I would totally recommend this service!!’
