There's no single number that fits every house in this service area, and we're not going to invent one. What drives the final price is the opener itself (chain, belt, or direct-drive, with or without battery backup), whether your existing bracket and header can take the new unit or need rework, and whether the house still has the original wiring from whenever it was built. On a lot of the stock in this area - a mix going back to the 1960s and 70s in several of the older neighborhoods - the header framing and electrical runs weren't sized for today's openers, so a straight swap sometimes turns into a small carpentry and wiring job. Homes built later, into the 2000s, usually go faster because the bracket spacing and power already match modern units. One honest limitation: we can give you a tight number once we've looked at your door and opener in person, but we won't quote a firm price sight unseen, because the two biggest cost drivers - header condition and wiring - aren't things you can describe accurately over the phone.
