"Our facility warehouse roll-up door was binding at top clearance and stalling the motor. Granite Garage Doors dispatched a commercial service team within an hour. They serviced the counter-balance springs, tightened the guide tracks, and adjusted the limit switches. Reliable, licensed pros who know commercial overhead hardware thoroughly."
"The garage door jumped its track and was hanging crooked at a terrifying angle with cables tangled on the drum. Called Granite Garage Doors's emergency dispatch and someone was at our driveway in 45 minutes. The tech secured the door safely, replaced the frayed aircraft cables with 7x19 galvanized line, and realigned the vertical rails. Highly recommended for emergency repairs in New London."
"Our door kept stopping and reversing whenever it got about two feet from the ground. Called Granite Garage Doors and their technician arrived the same afternoon. Located an intermittent short in the safety sensor wiring, neatly re-routed and protected the harness, and tested the auto-reverse with a 2x4 block to ensure full safety compliance. Fair pricing and friendly service."
