How Long Does Impact Window Installation Take? The Honest Timeline
Two clocks run on every impact window project, and confusing them causes most timeline surprises. The install clock is fast: crews average 30 to 90 minutes per window, and whole homes finish in one to three days. The project clock is longer: manufacturing lead times, permitting and inspection wrap the fast install in a six-to-twelve-week calendar. Here is the honest breakdown of both, and how to schedule smart in a state where everyone remembers windows in September.
The one-sentence version: Days on site, weeks on the calendar, one to three installation days inside a six-to-twelve-week project driven mostly by product manufacturing.
The Project Calendar, Stage by Stage
Week zero: the free in-home measure, every opening sized, products selected, exact quote delivered. On approval, two clocks start in parallel: manufacturing (your windows are built to order, typically four to ten weeks by product line and season) and permitting (your city or county processes while the factory builds). Then installation, the fast part below, then final inspection closes the permit and your wind mitigation inspection documents the insurance credits. Six to twelve weeks contract-to-credit is the honest planning number.
Installation Days: What Actually Happens
Crews run opening by opening: old unit out, opening prepped, new unit anchored to the tested schedule, shimmed square, flashed and sealed, 30 to 90 minutes per standard window, longer for doors and oversized glass. A 10-15 window home is commonly one long day; larger homes with sliders and entries run two to three. The iron rule: every opening cut is weather-sealed the same day. Your home is never exposed overnight, whatever the forecast.
What Moves the Timeline
Product choice moves it most: standard vinyl lines run the short end of lead times, custom colors, oversized and specialty systems the long end. Season moves it second: post-storm and pre-season surges stretch every factory in the state, spring orders install in calm; September orders join a queue. Jurisdiction moves permits modestly, and our project managers keep all three clocks visible from day one.
Scheduling Smart in Florida
The pattern to beat: half the state remembers windows when a storm is named, and lead times double. Ordering in the calm months, fall through spring, buys shorter factory queues, calmer install scheduling and full protection before June. Our best-time-to-buy guide maps the seasonal arithmetic, including how grant timing fits the calendar.

Frequently Asked Questions
How long does it take to install one impact window?
Experienced crews average 30 to 90 minutes per standard window opening, with doors and oversized units running longer. The install day moves fast; it is the weeks before, product manufacturing and permitting, that set the real calendar.
How many days does a whole-home installation take?
Most single-family homes complete in one to three on-site days: a typical 10-15 window home is often one long day, larger homes with doors and sliders two to three. Every opening cut is weather-sealed the same day, your home is never left open overnight.
What is the total project timeline from contract to done?
Plan six to twelve weeks: measure and engineering first, then manufacturing lead times of roughly four to ten weeks depending on product and season, permits processed in parallel, then the one-to-three-day install and final inspection. Ordering before hurricane season beats the rush.
Can I live in my home during installation?
Yes, virtually everyone does. Crews work opening by opening, room by room, with dust protection and same-day sealing; normal life continues around the work, and pets simply get a closed door away from the action.
