"Our door kept stopping and reversing whenever it got about two feet from the ground. Called National 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."
"Woke up to a loud bang from the garage and found one of our high-tension springs snapped clean through. Car was trapped inside and I needed to get to work. Called National Garage Doors and their technician arrived in 35 minutes with fully stocked high-cycle oil-tempered springs on the truck. Quoted me a fair upfront price with zero surprise charges. Door was balanced, lubed, and running whisper-quiet in under an hour. Outstanding local service in Jacksonville."
"The door was making violent rattling noises every time it opened. National Garage Doors diagnosed worn-out steel rollers and misaligned track brackets. Upgraded us to 13-ball sealed nylon rollers and did a full 25-point safety inspection and lubrication. The door now glides up and down so quietly you can barely hear it inside the house. Honest, punctual, and top craftsmanship."
