The fault we see most in Olney isn't rot or rust - it's a door and opener that were fine for the house they came with in 1986 and are simply worn out now. Builder-grade steel doors from that era shipped with a single torsion spring sized for a lighter door than most owners want today, and the openers that came with them were chain-drive units with no battery backup and no rolling code security.
That 1986 median build year matters because it's a decade newer than the median across the rest of the area, where most housing landed closer to 1976. A newer build year sounds like good news, and mostly it is - but it also means a lot of Olney doors and openers are hitting their first real end-of-life failure right now, all around the same age, instead of being spread across two or three replacement cycles like they are in older neighborhoods.
The cold-climate factor doesn't help. A bare steel panel with no foam core flexes and binds in a hard freeze, and that's the kind of door most Olney houses got the first time around.
