This team got the job done right! Beautiful work with mortared flagstone walkways and chop block surround for garden area. Hard working, exceptionally skilled, and ever so friendly. Would recommend to anyone!

I am extremely pleased with my new mailbox, it is exactly what I asked for. Every detail was executed precisely according to my request, and I now have what I truly believe is the most attractive mailbox in my neighborhood. I couldn’t be happier with the results. From the very beginning, Mr. Simkins was highly responsive, professional, and attentive to detail. He promptly provided an estimate, and when I later informed him that I had chosen his bid, he quickly arranged for one of his team members to contact me that same day to schedule the project. His employees arrived on time, began work immediately, and completed the job within just a few hours. The craftsmanship and final outcome were outstanding. The pricing was very comparable to others in the area, making the entire experience even more satisfying. Overall, I am extremely happy with the results and would absolutely recommend their services. I would not hesitate to use them again in the future.

Phil and his crew did an amazing job adding stone to an addition and building a beautiful step outside of the house. I would definitely hire him and his crew again for any additional work.

The customer service is amazing, great ideas and communication and the workmanship is superb. I enjoy the look of my stone walkways, rose gardens and patio. I receive compliments all the time! Phil also enclosed some garden areas in stone and replaced the metal border. That improved the look of my outdoor area so much. It looks like a resort area! I would definitely rehire for other projects!

Extremely happy with the work preformed by Cornerstone Masonry. We had 2 projects preformed over the course of about 1 month and Phil and Tim were extremely easy to work with. The quality of the work is A++, these jobs would have been considerably more expensive but they priced very well.

We chose Cornerstone Masonry for a concrete retaining wall project with an amphitheatre built in the middle. They offered competitive reasonable estimates and actually offered what we didn't know we were looking for in chop block and flagstone. We thought we wanted a concrete wall with some texture or veneer decoration, but when we saw the chop block option we knew immediately that's the one. Phil, the project manager, has decades of experience in this business and is very knowledgeable of the craft. He and his small crew of Roger and James worked diligently and precisely to bring our idea to life. With Phil's suggestion we also had an area next to our driveway that was just stepping stones redone with flagstone. Tim, the owner, was always timely in communication and responsive to texts and calls from us with questions or concerns about the build. Cornerstone Masonry removed and hauled away our old railroad tie wall, built us an amazing beautiful wall with amphitheatre and slab, and did it quickly and efficiently. The end product looks great and we're ready to start hosting gatherings at the house! Thank you Cornerstone Masonry!

The project went seamless. From the initial meeting for the estimate and getting to know Timothy and his team leader to the cleanup of the finished project. The communication was constant and each step was explained in detail. Questions were welcomed and answered given as detailed as you needed. The pricing for our project was within some of the other estimates we received but the initial meeting is what set this team apart from the others. They did not make you feel rushed, detailed explanations and welcoming questions are signs of professionals. They also took care as not to harm our three tier garden and shrubbery by the garage.

The team at Cornerstone is great! Hard working with great attention to detail. They expanded our driveway by 36 inches and made a large pad for our trash cans and outside storage. I would recommend them without reservation!

When I contacted Cornerstone Masonry I was at the end of my rope! I had very bad experiences with several contractors while I was trying to get a new patio installed. I wish I had contacted them first! They exceeded my expectations in every way. They were professional, knowledgeable, hard working, and communicated well. They actually started my project a week Ahead of schedule. They took initiative and took care of things that they didna t really have to, but clearly they prioritize getting a job done right. My final result is beautiful. I highly recommend Timothy, Phil and Roger.
