Across the ten communities we work in - Bettendorf, Riverdale, Le Claire, Eldridge, Princeton, Blue Grass, Walcott, Buffalo, DeWitt, Camanche, and Grand Mound - the housing stock leans heavily toward the 1960s and 70s, with the broader range running from 1948 to as recent as 2001 and a median build year of 1973. The service area runs about 11,334 households, roughly 6,807 of them owner-occupied, and that spread shows up in the garages we open.
The older end still carries original steel sectional doors on torsion springs sized for hardware nobody stocks at the big-box store anymore, plus openers that have outlived two or three remotes. The newer end, closer to the 1990s builds, usually has safety-eye sensors and lighter rollers that wear differently and fail for different reasons - frayed cable rather than a cracked spring.
Riverdale, 2 miles out, and Le Claire, 6 miles out, tend to mirror Bettendorf's older stock closely, while Eldridge and Princeton mix in more of the newer builds. Knowing which decade a neighborhood mostly dates from tells us what is likely wrong before we open the panel, which keeps the visit shorter and the bill smaller.
