Munford sits 14 miles out from our Bartlett shop, and the houses here skew a little older than the area median. Across the ten communities we cover, the typical home was built around 1998, but Munford's median build year lands closer to 1994. Four years doesn't sound like much until you're standing in front of the opener. Mid-90s construction means more jobs with the early run of chain-drive openers and steel doors that were lighter-gauge than what went up a decade later. The torsion springs on these doors have usually been cycled for close to thirty years, and a lot of them are still the original factory spring - nobody's touched them since the house was framed. That's not a Munford quirk exactly, it's a build-year quirk, and Munford's stock happens to sit right in that window more than some of the newer pockets closer to Bartlett itself. Cold-moderate winters add their own wear on top of that age: steel contracts, lubricant stiffens, and a spring that was already near the end of its rated cycles is more likely to let go on a January morning than a June afternoon.
