I don't have a published price list for this page, so I won't quote a number here that isn't backed by a real estimate. What I can tell you is what drives the number for a house like the ones common in Erlanger: whether you're replacing one of the original narrow single doors or going to a wider double, whether the opener and track need to be replaced along with the door, and whether insulation gets added where there wasn't any before.
Household income in the wider service area runs a median of $80,814, and Erlanger itself sits close behind that at $78,420 - numbers that matter less for what a door should cost and more for the fact that financing and timing questions come up on nearly every call out here. Ask for the breakdown in writing before anything gets ordered: door, hardware, labor, and haul-away of the old one, listed separately. If a quote is a single lump number with no line items, ask why.
