Chris and his team did a great job at my house. His crew worked really fast and efficiently, getting the job done in a timely manner. My neighbor was shocked at how fast they worked. High quality craftsmanship. Chris gave an incredible price for this amount of work and was willing to work with me every step of the way. I highly recommend using CMC if you want an affordable quality mason job done.

What clients say about our retaining walls
Chris and his amazing team turned our boring backyard into the coolest yard on the block. Large patio, retaining walls, built in BBQ, bar, and a large gas firepit. I was given a price and timeline. Project was completed for what was quoted with no surprises and completed quickly. I highly recommend the CMC team to design and build your dream backyard!
CMC Enterprises did an awesome job on our new driveway, front steps and garden walls. This was our first big home project so we were a bit nervous, but they made the whole process super easy. Everyone was a pleasure to deal with and all my questions were quickly answered. I was impressed with how quickly everything was done and with the quality of work. Prices were very reasonable. Highly recommend!
Chris and his team did an amazing job with our semi inground pool retaining wall, steps, patio, and fire pit. The price was reasonable and the work is top notch. We couldn’t be happier with how it turned out and would definitely recommend CMC to everyone we know!
Shout out to CMC Masonry, my backyard came out beautiful! Used Nicolock Stone Ridge Graphite Pearl, came out way nicer than I expected. Thank you Chris. My wife and I are very happy, can’t wait till you do the driveway this summer. 5 stars!
We had an amazing experience with CMC Masonry for our backyard pool project! Chris, the owner, was fantastic. His communication was perfect from start to finish, keeping us informed every step of the way. His crew was punctual and ensured the site was cleaned up daily. The quality of their work exceeded our expectations. If you’re looking for reliable, professional, and top-notch masonry work, we 100% recommend CMC Masonry!
I hired CMC Masonry to address a deteriorating brick walkway and install a new flagstone patio, and the results exceeded all expectations. From the initial consultation, Chris and his team demonstrated outstanding professionalism. The quote was transparent, detailed, and fairly priced compared to other bids. The quality of the masonry work is truly top-notch. The brick repair is seamless and the new flagstone patio is a beautiful, level, and structurally sound piece of art. If you are looking for a reliable, skilled, and professional masonry company, I highly recommend CMC Masonry.
Highly recommended! I have been dreaming of creating my very own backyard oasis and thanks to the professional crew at CMC I can finally say my dreams have become reality! Chris and his team were extremely respectful and tidy the entire time. After seeing the exquisite masonry surround, steps and patio area leading into my garden that matches perfectly, I simply cannot wait to show it off. It looks better than I could have ever imagined.
We had an incredible experience with CMC Masonry for the pavers around our pool. From start to finish, their work was top notch. They handled everything from digging out and properly preparing the area to making sure the pavers were installed exactly how we wanted. The attention to detail was outstanding and the finished product looks absolutely beautiful. Chris, the owner, is truly amazing to work with. He is responsive, honest, and genuinely cares about doing the job the right way. We were so impressed we had them do our driveway as well, and they even added a basketball court. Highly recommend.
Retaining Walls questions
How do you keep a retaining wall from leaning or failing?
A compacted gravel base, a buried first course, drainage stone and a perforated pipe behind the wall, and geogrid on taller walls. Water pressure is what pushes walls over, so we plan drainage from the start.
What materials can I choose from?
Segmental block from leading manufacturers such as Nicolock, plus natural stone and stone veneer. We bring samples to match your patio and home.
Do taller walls need a permit or engineering?
Requirements vary by town. For taller walls we'll tell you what your town needs and coordinate engineering when it's required.
