"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 Keller Garage Door Service 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 San Marino."
"The door was making violent rattling noises every time it opened. Keller Garage Door Service 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."
"Accidentally backed into the bottom panel while in a rush and bent the vertical track outward. Feared we would need an entire replacement door, but Keller Garage Door Service was honest and showed how reinforcing the bottom strut and straightening the guide rails would restore full function safely. Saved us over $1,200 compared to other quotes. True integrity."
