Robert Schneider

Grayson Contracting exceeded every expectation from start to finish! From the very first conversation, their professionalism, honesty, and attention to detail stood out. They didn’t just complete the work — they took the time to understand my vision, offered creative solutions, and executed everything flawlessly. The craftsmanship is top-notch, the communication was consistent and clear, and every deadline was met exactly as promised.

What really impressed me was their pride in their work — it’s rare to find a contractor who treats your home or project with as much care as if it were their own. The crew was punctual, respectful, and left the work area spotless each day. It’s clear they value quality, integrity, and customer satisfaction above all else.If you want a contractor you can trust to deliver exceptional results and a stress-free experience, Grayson Contracting is the one. I wouldn’t hesitate to hire them again and will be recommending them to everyone I know!

Kris Mclaughlin

Nate and his team did a great job on our siding and painting project. Nate is very responsive and made sure we received the results we expected. We would recommend Grayson Contracting.

We used Grayson Contracting to replace our siding, trim and also paint our whole house. We could not have asked for a better experience. Nate was very responsive and addressed all my questions and provided great recommendations. The crews were also great to work with, showed up on time and communicated with me throughout each phase of the project. I was thoroughly impressed with the quality of the work. We could not be any happier with the end result. I will be recommending Grayson Contracting to all my friends and family.

We received some pretty major storm damage to our house. Exterior wise we needed all siding replaced, trim etc, along with a new roof and gutters. We were really happy with the PM (Will) who guided us through the process. Even providing his cell # we could text on. When replacing the siding they found a couple of internal issues with the exterior that they all sorted included in the price. My new Hardy siding looks absolutely fantastic now - better than my house did when I initially bought it! Very happy with their work, attention to detail and going above and beyond to ensure we were happy. When our family visited soon after we received many compliments about the siding the color. And to top it off! No more woodpeckers pecking anymore as it’s hardy siding! Very happy with it and highly recommend Grayson for any siding issues in Parker- they managed everything from my hoa, to even knowing the local wildlife and what worked well color wise in the neighborhood. See attached for the photos of my house before and after so you can see the positive transformation the siding had!
