Garage Door Opener Repair & Installation · Mercer Island
Garage doors in Mercer Island take a beating from wet Washington winters — damp gets into bearings, cold stiffens grease, and springs that were already worn choose the coldest morning of the year to let go. We handle those calls every day.
Openers fail in fairly predictable ways: a stripped nylon gear on a chain drive, a cracked belt, a logic board that took a power surge, or safety sensors knocked out of alignment by a bike handlebar. Each one produces different symptoms, and only some of them are worth repairing.
We diagnose the opener as a system — motor, gear, rail, trolley, sensors, wall control, remotes and the door itself — because a healthy opener straining against an unbalanced door will fail again no matter how many parts you replace. Where repair is not economical, we install belt-drive or wall-mount units and program every remote, keypad and app before we leave.

Called at 11pm on a Sunday and an actual person answered. Door was stuck open and they got it secured that night, full fix the next morning.
Trevor A.Emergency service · Mercer Island, WARollers sounded like a freight train. Nylon replacements and it is a completely different door now.
Emmett S.Roller replacement · Mercer Island, WAOur shop has three bays and one was down. They had the rolling door back in service the same afternoon and set us up on a maintenance schedule.

Most doors are worth repairing. Springs, cables, rollers, hinges, tracks, openers and individual panels are all replaceable. Replacement makes financial sense when the panels are rusted through, multiple sections are damaged, or the repair bill starts approaching a meaningful share of a new door.
Usually a broken low-voltage wire or a failed wall console — both are inexpensive and quick. It occasionally points to a logic board fault, which we can confirm on site.
It depends on the part that failed. A tune-up or sensor realignment sits at the low end, roller and cable work in the middle, and torsion spring replacement or a new opener at the higher end. You get a firm, itemised price in Mercer Island before any work begins, and that number does not move once the job starts.
We do both. That covers insulated steel, carriage house, modern flush and glass panel doors, plus belt-drive, chain-drive and wall-mount openers with Wi-Fi and battery backup. We measure, quote, install, balance and haul the old door away.
A standard spring is rated around 10,000 cycles, which is roughly seven to ten years for an average household. Open and close the door four or more times a day and that drops sharply. High-cycle springs are worth the small upgrade if your door works hard.
Look at the springs above the door — a clean gap in the coil means a broken spring and the door should not be forced. Otherwise check that the opener has power, the wall button works, the photo-eye sensors at floor level are aligned and clean, and the door is not locked or disengaged from the trolley. If the door is heavy to lift by hand, stop and call.
