What Our Customers Say

We’re great at what we do but don;’t just take our word for it, see what hundred’s of satisfied customers have to say.

When we decided to go with KobyCo Door & Window. for our new replacement windows, it was the best choice we could have ever made. The staff and sales people were friendly, personal and knowledgeable. We toured the showroom and then they helped us pick the right windows for our home. Their installation crews were the best, working as if they were working on their own homes. They were professional and courteous and answered all of our questions. The result is just like Kobyco promised. Our home outshines all others in the neighborhood. Thank you.

We were referred to KobyCo Door & Window. for new interior doors by our neighbor who highly recommended them. Our neighbor really didn’t tell the half. Kobyco immediately made us feel relaxed and secure. They provided the interior doors and installed them expertly, along with the trim we picked out to go with the doors. Excellent is the only word that describes Kobyco. I have told several others about you. Our home looks beautiful!

My master bedroom closet was a mess. No matter what I did to it, I couldn’t get it organized right. I went online and saw Kobyco’s website. So, I called them and they told me to email the dimensions of the closet. I did and when I saw the sketches they came up with I was sold. They quickly updated my closet with organizers and I am thrilled. Thank you Kobyco for getting me organized.

The home I purchased in Chicago was perfect for my family, but I needed to update a few things, the windows, and the front entry door for starters. Also I had always wanted a retractable awning for the back of my home. I made an appointment with a Kobyco sales person and the rest is history. My home looks awesome with my new vinyl replacement windows. The retractable awning keeps the sun and other weather from spoiling our outings. My front entry door is elegant and just the kind I envisioned. Installation was done by experts. Thank you Kobyco. I am planning more remodeling projects and you’ll be doing them all for me.
