The obvious assumption is that a double garage door costs roughly twice what a single costs — more material, more width, more labor. In practice the gap is smaller than that, because a lot of the cost in any installation (hardware, opener, labor setup) doesn't scale linearly with width.
Real installed price difference
- Single door, Traditional, non-insulated: roughly $1,450–$2,000 installed
- Double door, Traditional, non-insulated: roughly $2,350–$2,850 installed
- Single door, Traditional, insulated: roughly $1,750–$2,200 installed
- Double door, Traditional, insulated: roughly $2,550–$3,100 installed
That works out to roughly 40–60% more for a double door, not double — because a large share of an install (tracks, hardware sets, opener, labor setup and calibration) is priced per door rather than per square foot of panel.
Other differences beyond price
- A double door needs a heavier-duty opener and torsion spring setup rated for the extra weight and width
- Labor time is longer for a double — more panels to hang, align, and balance
- Two single doors side by side (common on older homes) is a different job than one true double opening, and usually prices closer to two single installs
- Haul-away of the old door is priced separately and costs more for a double ($135 vs. $95 for a single) since there's more material to remove
Which one should you get?
If your garage already has a true double-wide opening, replacing it as one double door is almost always simpler and often cheaper than running two separate single-door installs. If you're weighing whether to convert two singles into one double opening, that's a structural change — worth discussing at your free on-site inspection rather than assuming it's a simple door swap.
Our wizard prices your exact configuration — single or double, insulated or not — and gives you an installed price in about two minutes so you can compare the real numbers side by side.
