Expert Partners Agree

“There are only a few times in your life when you come across a work ethic that is irreproachable….From the very first meeting with Terra Firma, it was apparent that Don is the ultimate expert in retaining wall engineering. Up until we met Don, we had met all walks of retaining wall contractors who gave us variations of the razzle dazzle sales pitch. Don is easily a cut above. He is honest, easy-going, very communicative, straightforward, and always has a solution for even the most challenging engineering situations.”
IVY LUMIA
“The crew was efficient, thorough and extremely professional. This company paid great attention to the littlest detail. My husband and I were very impressed with how the project was managed. Once the wall was completed, the guys cleaned up the site really well: other than the new retaining wall, it was hard to imagine that something of this scope even took place in our back yard!”
NATALIE PARSONS
“We hired Terra Firma to build a new retaining wall in our backyard. Our old wall was wood and falling apart, and we knew we had to replace it before it collapsed. Don was very polite and knowledgeable. After visiting the site, he delivered a folio with a detailed plan for the new precast concrete block wall. We liked the design and decided to go ahead with the project. The crew was tidy, courteous, and efficient. The wall was built according to the timeline they had provided at the start. I would definitely recommend Terra Firma!”
