Tell us the size of the door, what it's made of, roughly how old it is, and what it's doing wrong. Send a photo if you can. We'll give you a number over the phone for straightforward jobs - a broken spring, a noisy roller, a dead opener - and a range for anything where the track, the frame, or the panel damage needs a look in person before we can commit to a price.
The moderate heat here doesn't do much to steel doors directly, but it does affect which materials and lubricants we recommend for openers and tracks left exposed in a hot garage for years. That's a small detail, but it's the kind of thing that only comes up once we're actually there. Call (209) 435-1822 or stop by 275 N Main St and we'll start from there.
