Champlin sits apart from a lot of the other areas we cover. Across the wider service area, houses mostly date to the 1960s and 70s, with the overall stock running from 1957 to 2005. Champlin's median build year lands at 1988 - a good twenty years newer than the typical house we work on elsewhere. That matters more than it sounds like it should. A house built in 1988 came with a different garage door section profile, different track widths, and usually a chain-drive opener installed as original equipment rather than retrofitted later. With 8,699 households in Champlin, that's a lot of garage doors built to a fairly consistent late-80s spec, which makes diagnosing a fault faster once we know what we're looking at - but it also means the hardware isn't interchangeable with the older doors we see closer to the lake towns.
