The houses in Lolo mostly went up around 1995, newer than a lot of what we see closer into Missoula, where stock runs back to the 1970s. That means fewer of the original one-piece doors and side-mounted torsion setups that plague older neighborhoods. What you get instead in Lolo is mid-90s steel sectional doors nearing the end of their service life - galvanized skins that have taken twenty-plus winters of cold-band weather, insulation that's sagged or separated from the panel, and the first-generation chain-drive openers that came standard in that era. Those openers still run, mostly, but the gears inside are plastic and they're due. The cold band here is severe, and a door built in 1995 wasn't always insulated to a standard anyone would call good by today's numbers. That combination - decent bones, dated insulation, aging opener - is the typical call we get from Lolo, not a door that's actually failed yet but one that's clearly on its way out.
