"I have had two issues since they installed the new sump pump and irrigation. Issue number one was water still getting passed the new concrete. The other issue is that the new concrete was not level at all which has caused issues with the new flooring I installed. However, their customer service is top notch and will work hard to take care of you."

"Spencer and crew were great. They arrived on time and finished ahead of schedule. The new patio looks excellent. They cleaned up the job site. They even helped me make step since the new concrete patio is thicker than before, without charging extra. I would definitely recommend them to all my friends needing any concrete job done."

"We hired Jose last summer (2025) to remove some flag stones in the back yard and move them to the front walkway as well as put in a 16x14' concrete slab in the back yard. We interviewed 4 other contractors but he was the only one that gave us ideas on how to make it better than I could have imagined! What originally started as a single concrete slab in the back yard turned into a show piece walkway in the front yard and a back yard patio that was nice enough to add a gazebo! You would think that with all the extra add ons it would have been way over budget but it ended up costing much less than all the other quotes! We are looking at having Jose put in a new 28'x28' slab in the other side of the yard for a possible basketball hoop or, gosh, anything. I really recommend this company. Jose is very personable, professional, and very very qualified. Thanks Again Jose!"

"Terra Firma folks explained things clearly, did the needed filling with their foam filler and patched the fill holes. All done in just a few hours. Sure beats the time and cost of tearing up the concrete, bringing in fill and re-pouring. We've referred several family and friends. Recommend TR highly."

"Friends and neighbors who know what our basement looked like before are stunned by the gleaming concrete floor. Its warm brown stain and unusual character make you forget you're in a basement at all, thanks to the great job done by Alan and his crew at Your Concrete Guy.
The floor was in terrible shape: parts of it had been tiled, parts painted, parts dug up and badly patched, and all incredibly uneven. After consultation and helpful advice from Alan, we opted to have the floor grinded and skim-coated before staining. We learned that staining a concrete floor takes faith: It's not an exact science because every floor responds a little differently to the stains—even after skim-coating. From a color and design standpoint, we didn't know exactly how our floor would look when it was finished. But Alan had prepared us well and together we adjusted here and there along the way to achieve a great final result.
Alan's crew was punctual and courteous and the job stayed on budget and on schedule. After they finished, we covered the floor and proceeded with the final renovation. Now the floor is uncovered and Alan is completing some after-construction touch-ups. I would recommend his company to anyone who is planning a concrete make-over.
