We started doing business with J M Specialties last year. We have found them to be the resident experts in commercial overhead doors in Chattanooga. They came recommended to us by our sister company across town in Chattanooga Astec Inc. After successfully finishing the install of a door from a previous supplier, they installed another higher quality door (with a 100,000 duty cycle spring) for us at a better price than we received the first door from previous less skilled supplier. We were impressed to the point, we had them do a complete PM on all our doors at our factory and have experienced no problems to date (approximately a year later). We will have them in again this spring for PM and we are taking quotes currently on new doors for this year. Good People.
