If your Saginaw house was built close to that 1999 median, your door and opener are now at the age where original hardware starts failing on its own schedule, not because of damage. Springs rated for a certain number of cycles reach the end of that count right around 20-25 years in, which puts a lot of these doors in the replacement window right now. The honest answer on a lot of these jobs is that spring replacement alone, done right, buys another decade - full door replacement is rarely necessary unless the panels are dented or the track is bent. We'll tell you straight if a repair isn't worth it, but on steel doors this age, that's the exception, not the rule. One limit worth knowing: we don't stock every opener logic board on the truck, so a board swap on a less common brand can mean a short wait on the part.
