We don't do new garage construction or structural framing work - if the opening itself needs to be built or widened, that's a carpentry or general contractor job, not ours. We also don't do gate openers or commercial roll-up doors; our work is residential garage doors.
We won't quote a full replacement over the phone with any confidence. Door width, headroom, ceiling slope, and the condition of the existing track all change what hardware fits, and guessing at those numbers from a description is how homeowners end up with the wrong door ordered. If you want a replacement, we'll come look first.
And there are times a repair isn't worth doing. If a door is old enough that the track, rollers, and panels are all failing around the same time, patching one part just means we're back in a month for the next one. We'll say so plainly rather than run up a bill on a door that's better off replaced. That's not the answer every homeowner wants to hear, but it's the honest one, and it's cheaper for you in the long run.
