Keystone Heights sits about 20 miles from our shop in Gainesville, and the houses out here skew older than a lot of what we see closer in. Median year built here is 1970, which puts most garage doors and openers on a different clock than newer subdivisions. A door from that era is usually a single steel or wood-composite panel on a torsion or extension spring setup that's been replaced at least once, maybe twice, since the house went up. The brackets, the track gauge, the drum sizes - none of it matches what ships on a door today. If a torsion spring on one of these older doors lets go, we're not always grabbing an off-the-shelf part; we're matching wire size and wind to hardware that predates current standard kits. That's not a knock on the houses - they're solid - it just means the fix takes a little more diagnosis before the truck leaves the shop. We won't guess at a spring size over the phone for a door this old; we measure it in person.
