What’s the Best Time of Year to Schedule Impact Window Installation in South Florida?
There’s no bad month to install impact windows in South Florida, but the window between November and March tends to offer the smoothest scheduling experience. Crews are generally more available, permit offices process paperwork faster, and you avoid the chaos that kicks in every June when homeowners scramble before hurricane season peaks. That said, installation can happen any time of year without compromising the quality of the finished product.
Why Timing Actually Matters More Than Most Homeowners Think
The Hurricane Season Rush Is Real
Every spring, usually starting in April, phone lines at window installation companies get noticeably busier. Homeowners who watched a named storm clip the coast the previous fall finally pull the trigger on replacing their old single-pane windows. That surge in demand means longer lead times for materials, longer waits for licensed inspectors, and sometimes, longer gaps between your signed contract and the actual install date.
In Boca Raton, some homeowners have reported waiting 12 to 16 weeks for an install that would have taken 6 to 8 weeks if scheduled in January. The glass itself is the bottleneck. Impact-rated laminated glass is ordered per project and manufactured to spec, so it’s not sitting on a shelf waiting for you.
Permits Don’t Pause for Storm Season
The permitting process for a full-home impact window replacement in Palm Beach County requires a licensed contractor to submit drawings, product approvals, and sometimes structural documentation. During peak demand months, county building departments can back up by several weeks. Scheduling your project in the off-season means your permit is more likely to move through review quickly, and your install date stays on track.
You can read more about what the process typically looks like on the STS Impact Windows FAQ page, which breaks down common questions about timelines, inspections, and approvals.
What to Think About Before You Book Your Install
Material Lead Times Vary by Product Line
Not all impact window products have the same lead time. Some manufacturer lines ship within three to four weeks; others, especially custom sizes or specialty frame finishes, can run eight weeks or more. Brands like PGT and CGI are widely stocked in South Florida, but the specific configuration for your home still has to be ordered. Knowing this upfront helps you plan around events, travel, or lease renewals if you’re a landlord.
Weather During Installation Is a Minor Factor
South Florida’s afternoon rain pattern, especially from June through September, does slow down exterior installation work. Crews typically start early and can lose time to heavy afternoon storms. That doesn’t mean summer installs are a problem, only that they may take an extra half-day compared to a dry-season job. For most homes in the area, a full install wraps up in one to three days regardless of season.
If your project is larger, say 20-plus openings in a sprawling ranch-style home near the City of Boca Raton, build in a buffer day during summer months just in case weather interrupts the schedule.
Get Your Quote Before You Need the Windows Done
The single biggest mistake homeowners make is calling a contractor in May hoping to have new windows before July. By that point, the queue is full. If you want protection in place before the Atlantic hurricane season hits its peak in August and September, you need to be booking your project by January or February at the latest. A free estimate costs nothing, and locking in your spot early is the difference between being protected and being on a waitlist.

Related Questions
Do impact windows need to be installed before or after other exterior renovations?
Windows should go in after any major stucco repairs or exterior wall work is done, but before painting or interior trim finishing. Installing them in the right sequence prevents damage to new frames and avoids having to redo caulking or sealant work around freshly painted surfaces.
Can I live in my home while impact windows are being installed?
Yes, and most homeowners do. Crews work one section of the house at a time, so openings are only exposed briefly before the new unit is set and temporarily secured. There will be noise and some dust, but there’s no reason to vacate for a standard residential window installation project.
