We work on residential garage doors and openers: broken springs, snapped cables, bent or off-track panels, worn rollers, opener repair and replacement, and full door replacement when a repair isn't worth doing. We don't do commercial roll-up doors or gate systems, and we'll tell you that on the phone rather than let you find out when we're standing in your driveway.
What can't be priced sight unseen: rot or rust in the framing around an older door, hardware that's been mismatched by a previous repair, or a spring system where the size and cycle rating aren't obvious from a phone description. Winters here get cold enough that metal contracts, torsion springs lose tension faster, and a door that was borderline in October can fail outright in January - none of that shows up as a line item until we've got eyes on the actual hardware.
One honest limit: if your door or opener needs a part with a long lead time, we'll tell you the wait up front instead of guessing at a date. And if replacement is cheaper over time than another repair on an old door, we'll say that too, even though it's a smaller job for us than fixing the same door twice a year.
