+5% versus the national baseline

Three counties set the rules for the entire state, so jurisdiction lookup is unusually simple — but coastal Sussex County adds flood elevation requirements.

The formula
Cost = door price x insulation multiplier + opener + haul-away + labor
A double door costs roughly 55–70% more than a single, not double — the labor is nearly the same for both.

Frequently asked questions
How much is a new garage door installed?
Most single doors run $1,200 to $2,400 installed and double doors $2,000 to $4,500 in 2026. Custom wood and carriage-style doors run well above that.
Do garage doors need a permit?
In hurricane-prone states yes — the door is a rated opening and needs a wind-load-approved product with a permit. Elsewhere, replacements often do not require one.
