Gary was very friendly, explained the process, and gave us options when we had him look at our old, cracked, and crumbling stairs. He arrived when he said he would and I am very pleased with the quality of his work. He responded to my messages quickly and was glad to answer my questions. Would recommend and would use again if I need more concrete work done.

Gary and his team are fantastic. Looking for quotes Gary was there when he said he would be, recommended where the site of the monolithic slab should be and came in on budget. A lot of prep was needed with the landscape. Gary went above and beyond to make sure drainage was factored in and that the ground was compacted well. After he was done I had an Epoxy floor put on top of the slab and the installer said this was one of the best slabs he seen in a long time. I would definitely hire Gary again.

I had a 23-year-old asphalt walkway that I wanted to replace. It was suggested to me to use concrete since I also wanted radiant heat installed. I was referred to Gary. He called me soon after I reached out, came to my home to see the job, and discussed all of my options with me. He worked with my radiant heating installer to coordinate the work. I am extremely pleased with my new walkway. It is beautiful and the color is perfect with my new deck. Gary used a broom finish technique and also framed the walkway with a picture frame look. I never knew cement could look so classy!
