"The door was making violent rattling noises every time it opened. STI Garage Door 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 STI Garage Door 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."
"Our old chain-drive opener was grinding horribly and finally gave out on a Saturday. The technician from STI Garage Door walked me through replacement options clearly without any high-pressure upselling. Installed a belt-drive smart opener with battery backup and camera. Programmed both vehicle remotes and helped us configure the smartphone app before leaving. Extremely professional and clean work."
