“Just had my new entry door installed & the guys were absolutely wonderful making sure the door fit properly! Very nice guys & cleaned up as they went along. I couldn’t ask for better guys! Extremely professional & I’d recommend this company to anyone!”
“I loved working with this company. We needed a custom-sized front door for our 90-year old home, and Kevin came out to take measurements, go over my options, and helped me order what we were looking for. The installation was smooth and easy, and my door is now sealed well to keep the cold out in winter, and it looks beautiful. I’d absolutely recommend this company and will use them again if we ever need doors or windows.”
“All in all, I am very happy with my decision to employ Mills Window and Door to replace the 12 windows in my house! I got three quotes for the work, of which Mills was second price-wise. However, the cheapest was one of the larger-scale nationwide companies and Mills was only slightly more. I definitely feel that I got the added value not only in the window quality, but also in the outstanding customer service they provided. I will not hesitate to employ Mills in the future and would highly recommend them to anybody!”
