Quick Answer
Most whole-home impact window installations in Pensacola take 1–2 days on site, at roughly 30–60 minutes per window. The full project — measure, order, permit, install, inspect — usually spans 4–8 weeks, with custom manufacturing accounting for most of that time.
“How long will this take?” is the first question most homeowners in Pensacola, Gulf Breeze, Pace, and Milton ask about impact windows — and the honest answer has two parts. The installation itself is fast: a trained crew replaces most whole homes in a day or two. The overall project takes weeks, because impact windows are custom-built for your exact openings. Here is the full timeline, step by step.
The impact window timeline at a glance
| Stage | Typical time | What happens |
|---|---|---|
| Free in-home estimate | 60–90 minutes | Every opening measured; glass and frame options quoted |
| Ordering & manufacturing | 3–6 weeks | Windows custom-built to your sizes and wind-zone specs |
| Permitting | Runs in parallel | Contractor files the building permit with your city or county |
| Installation | 1–2 days for most homes | Old units out, new units set, anchored, sealed, and finished |
| Final inspection | Scheduled after install | City or county inspector verifies code-compliant installation |
Why the windows take longer than the installation
Impact windows are not shelf products. Each unit is manufactured to your opening's exact dimensions, with laminated impact glass and Design Pressure ratings matched to the Florida Building Code wind-borne debris requirements that cover much of the Pensacola area. That custom build is what makes the 3–6 week lead time normal — and why ordering before hurricane season is the smart play. After a named storm, demand spikes across the Gulf Coast and lead times stretch.
What installation day actually looks like
- Protection first. Floors, furniture, and landscaping around each opening are covered.
- One opening at a time. The old window comes out, the opening is checked for rot or hidden damage, and the new unit is set, shimmed, and anchored to spec.
- Sealing and waterproofing. Proper flashing, insulation, and sealant are what make a window hurricane-ready — this is where construction experience shows.
- Finish and clean-up. Interior trim, exterior caulk, stickers off, glass cleaned, and every old unit hauled away.
At roughly 30–60 minutes per window, a 10–15 window home is typically finished in one to two working days. You can live in the house the whole time.
What can make it take longer?
- Hidden damage. Rotten framing or termite damage behind an old window must be repaired before the new unit goes in. Because Local Window Guy is powered by Built By Deel Construction, a licensed residential contractor, those repairs happen on the spot — no waiting on a second company.
- Masonry and mud-set openings. Common in older Pensacola brick homes, these take more prep than a standard fin or flange install.
- Second-story and oversized units. More handling time, sometimes more crew.
- Weather. Crews will not leave openings exposed in heavy rain; a stormy day can push completion to the next morning.
The bottom line for Pensacola homeowners
Plan on 4–8 weeks from signed quote to final inspection, with only 1–2 days of that inside your home. Start the process well before peak hurricane season, and the disruptive part is over almost as soon as it begins.

Frequently Asked Questions
How long does it take to install one impact window?
A straightforward replacement typically takes about 30–60 minutes per window once the crew is set up. Second-story openings, oversized units, or repairs to rotted framing add time.
How long does a whole-house impact window installation take?
Most whole-home replacements in the Pensacola area are completed in 1–2 days on site. Larger homes, mud-set openings in brick, or hidden damage behind old frames can extend that to 3 days or more.
Why do impact windows take weeks to arrive after I order?
Impact windows are custom-manufactured to your exact opening sizes and glass package — they are not stocked on a shelf. Manufacturing lead times commonly run 3–6 weeks, and can stretch longer during peak season after a named storm.
Can I stay in my house during window installation?
Yes. Crews work one opening at a time, so your home is never fully open. Expect some noise and dust near the active room, and plan to keep pets and kids clear of work areas.
Does the timeline include a permit and inspection?
It should. Window replacement in Florida requires a building permit before work starts and an inspection after it is finished. Your contractor should handle both — permitting usually runs in parallel with manufacturing, so it rarely adds time to the overall project.
