We don't have a flat number to quote here without seeing the opening - door width, insulation level, and whether the opener needs replacing too all move the price, and we're not going to invent a figure that doesn't hold up once we're standing in your garage. What we can tell you is that a straight door swap on a standard 1994-era opening costs less than a job that also requires new track, new brackets, or opener replacement, so the honest answer is to get the on-site look before you budget. Irondale's median household income runs higher than some of the other communities we cover from McDonough, which tends to mean more owners choosing insulated steel over the base builder-grade option, but that's a preference, not a price we can promise in advance.
