We carry the rollers, hinges, cables, and track sections that fail most often on doors from this era - nylon and steel rollers, standard hinge sets, and galvanized track in the lengths that fit a typical residential door. Del Mar's mild coastal climate means the hardware here isn't fighting freeze-thaw cracking or wide temperature swings the way it would inland; when it fails, it's almost always from age and use, not weather stress. That's good news for parts availability - we're not chasing a discontinued track profile because the door survived a hard winter it was never built for. What we don't stock on the truck: full custom door panels or specialty low-headroom track kits, which sometimes have to be ordered. If your door needs one of those, we'll tell you up front instead of making you wait at home for a part that isn't coming.
