How long does it typically take to replace a garage door?

It typically takes 3 to 6 hours to replace a garage door for professional installers for single door, and 6 to 10 hours for double door, with most replacements completed in half day. Time to replace existing garage door includes removal of old door, which takes 30 to 60 minutes, including disconnecting opener, removing panels, tracks, and hardware. Installation of new garage door takes 2 to 4 hours for single 8x7 door and 4 to 6 hours for double 16x7 door, including installing new tracks, rollers, hinges, panels, torsion springs, and opener connection. Professional team of two installers can replace single door in 3 to 4 hours, double in 5 to 6 hours. If replacing opener also, add 1 to 2 hours. Additional time needed if framing needs repair, electrical work needed, or custom door with windows. DIY replacement takes longer, 8 to 12 hours for experienced DIYer and 1 to 2 days for beginner, due to complexity of torsion springs which are dangerous. Factors affecting time include door type, insulated steel faster than wood, size, single faster than double, and condition of existing framing. In Canada, Garaga and Richards-Wilcox dealers quote half day for replacement. So typically 3 to 6 hours professional, 1 day DIY, with most jobs completed in morning or afternoon, with minimal disruption, and new door operational same day.
