Waupun's housing runs older than the broader service area's median: the typical home here dates to around 1961, ahead of the 1970 median across the wider 24-town coverage area. That decade-plus gap matters because it's roughly a full generation of hardware changes - torsion spring sizing, drum style, and track mounting all shifted more than once between then and now. With 3,631 households in Waupun and a median income near $66,931, most of what we see are original garages retrofit with a replacement opener bolted onto framing that was never built for one, or a door swapped once in fifty-plus years while the track and jamb hardware stayed original.
