We're not based in Hacienda Heights - the truck comes from Whittier, about 3 miles away - so factor that drive into when you call, especially if you're trying to get a door closed before you leave for work. Once we're on site, the job itself usually runs on the hardware, not the address. A straightforward spring swap on a standard double door is quick work. Where it slows down is when the door's age complicates parts: a 1968-era bracket or drum that isn't the common modern size means more time confirming fit before anything gets installed, not less. With roughly 16,498 households in this area, most of the doors we see here were built in the same narrow stretch of years, so once we've seen a few jobs on this side of the service area the hardware quirks stop being a surprise. First visit to a given street, though, expect us to measure twice.
