Chanhassen sits about 8 miles out from our Minnetonka base, and the houses here skew noticeably newer than what we see across the rest of the service area. The median build year here is 1993, while the broader area we cover runs from 1957 to 2005 with a median around 1977. That gap matters. A house built in 1993 came with a factory steel sectional door, a chain or belt-drive opener already wired for a wall console, and galvanized torsion hardware mounted on a header bracket - not the older side-mounted setups you'd find in a 1960s rambler. With 9,607 households in Chanhassen, that's a lot of garages built in roughly the same decade, which means a lot of garages hitting the same age-related failure points around the same time. We're not guessing at your door from a 1970s file - this area's housing stock has its own profile, and it's a newer one.
