Testimonials

"During my search for the ‘right’ window and door company. I took the time to shop around to familiarize myself with product and scope of work needed for the job. I am so lucky that a friend recommended King & Co., because they actually made the process and decision easier for me.
Right from the beginning. The King & Co. team made me feel confident that I was getting the best value, quality and service for what I needed to revamp my home. They were very helpful in walking me through the initial consultation stage right through the installation phase.
Not only was the project finished on time, the installers were amazing! They were so professional and really took pride in their work. Needless to say, the house looks amazing!"
