We don't quote a number here, because a rollup door on a Princeton warehouse and a sectional steel door on a strip-mall unit don't cost the same to fix, and we're not going to pretend otherwise. What we can tell you is what drives the number: whether the opener is original to the building or already a replacement, whether the springs are the factory set or something a previous tenant swapped in, and how much of the track and hardware is still 2012-era stock. Princeton's commercial building here is newer than most of the towns we cover out of Allen - median year built across the service area is 2005, and Princeton runs closer to 2012 - so a lot of what's on these buildings has never been touched. That cuts both ways. Newer means less rust and fewer mystery patches, but it also means most of these doors are approaching the point where the first factory spring set, rated for a fixed number of cycles, starts to fail. We'll look at the door in person before we say anything about cost, and we'll tell you plainly if a repair isn't worth it against a straight opener swap.
