Across this stretch of Lake County - Park City, Gages Lake, Grandwood Park, Old Mill Creek, Green Oaks, Grayslake, North Chicago, Lindenhurst, Wadsworth, Beach Park, Libertyville, Venetian Village, Round Lake Beach, Lake Bluff, Hainesville, Round Lake Park, Zion, Lake Villa, Round Lake, Mettawa, Winthrop Harbor, Long Lake, Antioch, Fox Lake Hills, Hawthorn Woods, Volo, Lincolnshire, Wauconda, Lake Catherine, Long Grove, and Hickory Corners - the housing stock as a whole runs from 1946 up to 2009, with the median build year landing around 1986. Most of the 53 named areas we work in are dominated by that 1980s-to-90s wave of construction.
We don't have a town-by-town breakdown of build years, so we won't pretend a house in Grayslake is older or newer than one in Wadsworth just because of the zip code. What we can say is what that 1980s-90s era means for a garage door: builder-grade openers with light-duty gear sets that strip after quarter-century of use, single torsion springs sized for the door weight of that decade (often undersized once a homeowner has added an insulated retrofit door on top), and steel tracks bolted with hardware that's rusted through in unheated garages.
This is a cold-climate service area, and that plays into it too - temperature swings work springs and rollers harder over a winter than a mild climate ever would, no matter which of these towns the garage sits in.
