Impact window lead times in South Florida, as of October 2026, run about six to ten weeks from signed contract to finished install on the fastest product lines, and three to four months on the slowest. Manufacturing is the long pole: the quickest major manufacturers are building standard impact windows in 4-8 weeks, the mid-pack runs 6-10, and the made-to-order and luxury lines run 10-16. Permitting, the step buyers worry about most, runs in parallel and rarely controls the finish date.
The wait is also seasonal in a way you can measure. Across the 19,633 window and door permits Miami-Dade County issued in the 24 months ending July 2026, a county record we collect and normalize, April issuance averaged about 930 permits a month against November's 624, roughly 49% higher. The spring rush before June 1 is not a sales story; it is visible in the permit ledger.
This guide gives you the brand-level numbers, what the clock actually measures, what adds weeks, why the season stretches every queue, and the specific moves that shorten your wait.
Impact Window Lead Times by Manufacturer: October 2026
Manufacturers rarely publish hard lead-time numbers, because the numbers move. The standard-window figures below come from our running six-manufacturer comparison, which we re-check on every update pass (last full update August 2026); where a manufacturer publishes its own figure, the notes column carries it.
| Manufacturer | Built in | Standard impact windows | Notes and published figures |
|---|---|---|---|
| ECO Window Systems | Medley, FL | 4-8 weeks | White and bronze are the stocked finishes; custom colors add a paint queue |
| EAS (Eastern Architectural Systems) | Fort Myers, FL | 4-8 weeks | Florida-built vinyl and aluminum; local delivery, no freight leg |
| CWS (a Pella brand) | Ocala and Miami, FL | 6-10 weeks | Four Florida plants; Pella's supply chain sets the pace |
| PGT (WinGuard) | Venice, FL | 10-12 weeks | Made-to-order line; the longest queue among the major brands |
| ES Windows (Tecnoglass) | Barranquilla, Colombia | 5-6 weeks | Dealer order terms allow 6-8 weeks of processing after full payment; the company's own FAQ quotes 90-120 days for unusual configurations |
| WinDoor | Orlando, FL | 12-16 weeks | Luxury tier; the factory date is quoted at contract |

ships from a Colombian factory yet runs one of the shortest queues, because Tecnoglass extrudes its own aluminum and laminates its own glass, so its window plant never waits on a glass supplier. Ocean freight and customs still sit on top of its production run, which is where the 90-120 day quote for unusual configurations comes from. Second, ES Windows is the one major manufacturer that publishes numbers at all; everyone else quotes at order, which is why the date on your contract matters more than the range in any table. Third, these ranges describe a normal market. During the 2020-2022 supply crunch, delivery on major Florida lines stretched to six to eight months, and after a landfall every number in this table can double.
These ranges are current as of October 2026. We re-check them quarterly and after any storm that hits Florida, so the date stamp above tells you which read you are looking at.
What the Lead Time Actually Measures
"Lead time" is not one clock; it is four running at once, and only one of them is long.
The project starts at contract, but nothing enters a factory queue until a technician has measured every opening, because impact windows are manufactured to the measured opening, not the catalog size. From the measure, manufacturing runs the 4-16 weeks in the table. Permit review runs in parallel with manufacturing, not after it, and a 2024 Florida law (F.S. 553.792) caps residential review at 30 business days; hiring a private provider for plans review cuts that clock to 20 business days, and to 5 on a single-trade residential permit like a window replacement. Installation itself takes 1-3 days for most homes, and the final inspection closes the job within about a week.
Add it up and the glass, not the government, controls your install date. Permit fees and county-by-county timelines are their own subject, and we cover them in our Florida impact window permit cost guide.
What Adds Weeks to an Impact Window Order
Four things reliably stretch the ranges above.
Custom colors and finishes. White and bronze move fastest on most Florida lines because they are the stocked finishes. A painted or anodized custom color adds a paint-queue step and usually an upcharge; our black frame impact windows guide covers the finish systems and what they cost in time and money.
Custom sizes and specialty shapes. Oversized fixed glass, arches, and multi-panel doors are engineered runs, not line items. That is why manufacturers quote them separately, and why ES Windows' own FAQ puts unusual configurations at 90-120 days against its 5-6 week standard queue.
HVHZ paperwork. In Miami-Dade and Broward, the permit package must match the product exactly: the Notice of Acceptance or Florida Product Approval number, the anchoring schedule, and the design pressures for each opening. A package that matches sails through the statutory clock. A mismatch means correction cycles, and each cycle burns a week or two.
Changing your mind. A glass or color revision after the order enters production restarts that unit's clock. Finalize selections at contract, not during manufacturing.
Why Hurricane Season Stretches the Queue
Every lead time in this article is a queue position, and the queue breathes with the season. Installation requests across the industry rise 300-400% in the May-August run-up, scheduling backlogs stretch to 6-10 weeks at peak, and manufacturers re-price into the demand. After an actual landfall it gets worse: lead volume jumps 300-500% within 30 days, and scheduling that ran 2-4 weeks extends to 3-6 months as damage repairs and deferred projects land in the same intake.
None of that is a reason to sit out the season; an order in the queue beats no order every time. The decision of whether to start a project mid-season is its own question, and our guide to installing impact windows during hurricane season answers it in full.
The November Trap: Ordering After a Storm Scare
Here is the pattern we see every year. A late-season storm brushes the coast in October, the Atlantic season runs through November 30, and a wave of homeowners who watched the cone all week decide to "get it done before next year." They call in November, alongside everyone else who had the same scare.
November is the worst-lit month on the calendar for that plan. Our Miami-Dade permit data shows November is the slowest issuance month of the year, reflecting holiday-shortened permit weeks and compressed crew schedules, while the post-scare demand wave is still working through every installer's intake. A project ordered in mid-November on a 10-12 week line lands in late winter, having waited through the holidays for a queue position an October order would have skipped.
The counter-move is to use the math in this article backward. If you want glass in the wall before June 1, a 4-8 week line ordered by March makes it with room to spare, and a January order clears even the longest queue in the table while beating the spring permit rush our data shows peaking in April. Our hurricane season preparation guide lays out that month-by-month timeline.
How to Shorten Your Impact Window Lead Time
You cannot skip the factory queue, but you can stop adding to it. Five moves matter.
- Favor stock sizes and standard finishes where the opening allows. Standard configurations in white or bronze on the fastest lines sit at the 4-week end of the range; every customization moves you toward the far end.
- Schedule the final measure within days of signing. The factory clock starts at the measure, so a measure that drifts two weeks pushes the install date two weeks.
- Show up permit-ready. A signed contract, the product approval documents for the exact units ordered, and a complete opening schedule let the permit run its parallel course without correction cycles. Ask your installer whether they work with a private provider for plans review; it cuts the statutory clock to 20 business days, and to 5 on a single-trade residential permit.
- Lock selections at contract. Glass, color, hardware, and grid decisions made once, before production, protect the date. Revisions restart the unit.
- Sort the money early. If the project depends on approval, arrange financing while the windows are in production rather than after they arrive, so funding never becomes the new long pole.
Next Steps
The fastest project is the one whose clock starts today: a free estimate gets your openings measured and your quote locked, so your order can enter the factory queue this week instead of after the next storm scare.
