| Project | Installation Time | Notes |
|---|---|---|
| 1 entry door (prehung, standard size) | 4-6 hours | Longer if trim or framing repair needed |
| 1 sliding or French patio door | 4-8 hours | French doors take longer due to swing clearance work |
| Entry door + storm door combo | 6-8 hours | Storm door typically added same visit |
| Multiple doors (3-4, whole-house refresh) | 1-2 days | Crew of 2 is typical |
These figures cover installation day only — the time from crew arrival to a finished, functioning door. The full project timeline, from your first call to a contractor through the finished install, is longer once you account for quoting, manufacturing, and permitting.
Manufacturing lead time is the single biggest driver of your overall timeline. Standard prehung steel or fiberglass doors in common sizes typically ship in 4 to 6 weeks from major manufacturers. Custom configurations — non-standard sizes, specialty glass, hand-painted wood finishes, or oversized patio door units — commonly run 8 to 10 weeks. During peak spring and summer season, some installers report booking 3 to 4 months out, so ordering early matters if you want a specific completion date.
The most common delay is rotted or out-of-square framing discovered once the old door is removed. Older homes frequently have door openings that have shifted or have water-damaged jamb material hidden behind trim. If the crew finds this during removal, expect 1 to 2 additional days for structural repair before the new door can be set. The second most common delay is a non-standard rough opening that requires a special-order size rather than a stocked unit — this is where a quote that quietly assumed "standard size" can turn into a multi-week surprise.
Permit requirements vary by jurisdiction and by scope. A straightforward like-for-like door swap (same size, same opening) often does not require a permit in many municipalities. Enlarging an opening, adding a new opening where there wasn't one, or replacing a door in a designated wind-borne debris or coastal zone typically does require one. Permit processing ranges from same-day in some municipalities to 2-4 weeks in others. Confirm with your contractor before you lock in an installation date, since a required permit that hasn't been pulled yet can push your start date back.
Yes. A single door swap leaves your home exposed to the outside for a matter of minutes to a couple of hours while the old unit is out and the new one is being set and sealed — most crews plan the removal and set to minimize that window, and will temporarily secure the opening if there's any delay. Multi-door projects are staged one opening at a time for the same reason. Expect noise, some dust from trim work, and a crew present for the day, but no need to vacate.
Ask specifically: What is the manufacturing lead time on this exact door, in this exact size and configuration? Is a permit required in my jurisdiction, and has it been pulled? What happens to the schedule if you find rotted framing during removal? Clear answers to these three questions prevent the most common source of frustration — a quoted "one-day job" stretching into a multi-week ordeal because of a lead time or permit step nobody flagged up front.
Manufacturing lead time, not install day, is what eats your calendar here. A standard door ships in 4-6 weeks; custom sizes or finishes push that to 8-10 weeks, so order early if you have a date in mind.
These are the questions homeowners ask most often before starting this project - what it costs, how long it takes, what a fair quote looks like and which details change the price. Each answer below is written to stand on its own, so you can read just the one you need.
