We do not publish flat prices because the two biggest cost drivers, door weight and spring wind type, vary house to house even on the same block. A double garage with the original heavier door from the early 80s needs different spring and cable specs than a lighter insulated door installed in a later remodel, so a number that fits one house would be wrong for the one next door. What you pay for is a correct diagnosis and a part that fits your door the first time, not a truck roll and a guess.
That difference is the whole job on an older door, where the wrong part on the truck means a second trip instead of a fix. We price the job, not the minute, and we tell you up front what is springs-and-labor versus what is a part we need to order. Some boards and hardware for older or less common units take a few days to source, and we will say so rather than pretend otherwise. We will also tell you honestly when a repair is the better value and when you are about to spend good money chasing a door that is already done.
