We just finished a renovation of our backyard using Keystone and it has overall been a great experience. The level of professionalism and service we saw from them beats any contractor we have worked with in the past. The quality of their work cannot be matched either.

From the start, Ron and his team were great to work with to design our dream space, which included a new deck and patio underneath with a built-in kitchen. As construction began, Wayne and his masonry team did an amazing job laying our new flagstone patio. Finally, Elmer was a great project manager to work during the construction phase. He always kept us up to date with the progress and any scheduling changes and made sure we were happy with the progress.

We can also verify firsthand that they will 100% stand by their work We had a couple minor cosmetic issues with some of the stonework and they responded right away and made sure everything was fixed up to our liking.

If we ever had a need for another project like this, there would be no question we would use Keystone.

We chose Keystone Custom Decks based on a strong set of reviews and a strong portfolio of previous work. Our salesperson, Joe, reviewed our project and helped bring our ideas to life with the design team. The design review process was thorough and well run. We enjoyed reviewing the plans, selecting materials, and finalizing the project. KCD made it really easy as they had all of the samples to review in the showroom. Once the project began, the crew, led by Sam and Mike, were amazingly efficient, clean, and organized. The KCD crew and subcontractors were all respectful, prompt, and great to work with. Our neighbors even commented on nice everyone was. Our finished project, which was sizable, looks great, was completed on budget, and will bring us joy for many years to come. While KCD wasn't the least expensive contractor we reviewed, we definitely got what we paid for. I would definitely choose them again and will refer them to friends and neighbors in the future.
