Most houses in Paradise Valley went up around 1985, which puts the original garage door and opener well past where anyone should expect them to still perform. A door from that era usually came with a single torsion spring sized for a lighter steel panel, and an opener with a chain drive that's loud by today's standard and often missing a working photo-eye safety sensor altogether - those weren't required when these doors went in. When a homeowner here calls about installing new, the complication isn't the door itself, it's the opening: thirty-five-plus years of settling can leave a frame slightly out of square, and jamb brackets that were fine in 1985 don't always meet a new door's hardware without shimming. On top of that, this part of the valley sits in a severe-heat climate band, which matters more for installation than people expect - vinyl weatherstrip and nylon rollers that spend summers against a hot steel frame wear faster here than they would somewhere milder, so the install has to account for that from the start, not get fixed later as a callback. We come out from our Chandler shop, about 20 miles away, so we plan the visit as one trip: measure, confirm the opening is square, and install, rather than a measure-now-install-later split.
