Customer service is five star! Two employees came on a Friday night to fix one of our windows. They were extremely professional, efficient and did an excellent job! From my first call to the office to the repair of our window, they were so kind and wonderful to deal with. Thank you!!

KD Exteriors have replaced all our exterior doors and windows as per our budget over the last 7 years. The craftsmanship is excellent from start to finish, their product from door thresholds, to trims, frames and hardware, to security system integration to product design and installation knowledge is amazing. Our last exterior french door was just completed today, beautiful! Thank you Kevin and Kim!
