Lake Fenton's median household income sits at $112,676, well above the $81,772 median across the wider service area we cover out of Fenton. That number matters here because it changes what homeowners do when a door comes off its track - more of them replace hardware outright instead of nursing along a bent rail. The housing itself is newer too. Median year built in Lake Fenton runs around 1993, a couple decades past the 1976 median for the broader area, where most stock went up between 1950 and 1994 across the 21 named communities we serve. Newer construction here generally means galvanized steel track on nylon rollers rather than the steel rollers and older extension-spring setups still common on the 1960s-70s houses closer to Fenton proper. That doesn't make Lake Fenton immune to off-track failures - it changes the cause. On this stock, we see it less from age-worn hardware and more from a single hard impact: a car bumper clipping the bottom section, or a roller bracket working loose because it was never torqued right at install. The fix, and the bill, follow from which one it is.
