What Our Customers Say

"They did an excellent job on our new roof!! Very pleased with their work."

"G&K did a phenomenal job on our home. From start to finish they worked with us to find exactly what we wanted, what worked for our budget, and guided us along the way. We are thrilled with how our home turned out. I was a real estate home inspector for 6 years and I can tell my home was built with quality and expertise. I would highly recommend G&K, I would definitely use them again if I ever build another house, but I see me and my family being this one for years to come."

"Building Our Dream Home with G&K Construction Was Wonderful; 10/10 Recommend! After having worked with a larger builder in the past, we were looking forward to working with a company that would do more custom work, while still a bit apprehensive about how the process would go. But working with Gary at G&K Construction was a completely different and much more positive experience. From the very first consultation, the process was tailored to what we wanted for our home."

"So many great features!!!! Personally a huge fan of the large long drive leading to the garage. Great curb appeal."
