"Westcott to some minor repairs/maintenance on my 2 garage doors. They were extremely noisy. Westcott quickly repaired them so they are quiet now and price was reasonable ($65)."

"Great experience - installers Alex and John came out the same day I had contacted DSI for a quote - my existing door was installed pretty poorly by the previous owner and had huge gaps around the edges, but they leveled it out, fixed the door, installed the operator and all the accessories in a short amount of time and left no mess behind. All in all, a perfect experience and I would recommend DSI to anyone."

"Everyone was clear and up front about all costs associated with our new garage door. They offered us options that fit into exactly what we wanted. And it cost a LOT less than we anticipated."

"Scott responded my request quickly and gave us a free inspection since he was around our area. Then he suggested me to replace the head instead of fixing it because that machine is pretty old and repair may cost more money because I would finally replace it. Scott is very professional and knowledgeable about garage stuff. He did a excellent job for the head, tune up and rubber seals. Will recommend him!"
