We run this job out of Stamford, about 6 miles from Greenwich, so the installation gets scheduled rather than handled same-day. That's not a complaint about Greenwich - it's just the honest shape of how the route works, and we'd rather say that up front than promise a window we can't hold.
When you call, we ask about the door's age, whether it's one-piece or sectional, and whether there's already a wired circuit near the header. Those answers change what we load on the truck. Across the wider service area there are 39,759 owner-occupied houses, and a good share of the older ones share this same wiring gap, so it's a question we've learned to ask before we show up rather than after.
