If you're noticing your door sagging at the corners, daylight showing around the edges even when it's shut, or the opener straining and reversing on cold mornings, that's consistent with an original door that's simply aged out - not something worth another patch repair. Across the roughly 12,335 households in our service area, this shows up most in the older pockets: Mesa Junction, the Lower East Side, Bessemer, Aberdeen, Belmont, and the North Side neighborhoods all carry a good amount of that 1960s-70s stock. If your door is original to the house and you're in one of those areas, odds are good the hardware underneath is original too. One honest note: if the opening itself is still square and the header's solid, a full install is often less work than people expect - it's the houses where the frame has settled that take the extra time.
