Impact Window Installation Timeline for Hurricane Season Preparation

Installing impact-rated windows greatly increases a home's storm resilience, and getting the timing right is crucial.

This guide lays out a realistic timeline you can use to plan work before storms arrive, with checkpoints for inspection, permitting, ordering, and installation.

Initial Steps for Impact Window Installation

Start with an inspection and measurements as early as possible. Most contractors will need a single site visit for assessment and accurate measurements.

An experienced window replacement company can confirm the cause with a quick inspection.

Permits commonly add time to a project, so factor them into your schedule immediately after measurements. In many Florida counties, permit review can take two to four weeks, sometimes longer during busy months.

Ordering and Scheduling Your Impact Windows

Order lead times are the next variable. Impact windows are manufactured to size and finish, so they rarely sit on a shelf. In most markets, expect factory lead times of roughly two to six weeks, depending on complexity and seasonal demand.

Reserve installation dates when you order the windows, to align crew availability with the expected delivery. A single-family home can often be completed in one to five working days depending on size and number of openings.

Managing Potential Delays

Account for unexpected site work, like replacing rotted framing or repairing stucco, which will add time and cost if discovered during removal. If repairs are needed, add at least a few days for carpentry, inspections, and weather-dependent work.

Weather is another wildcard. Even with a good schedule, heavy rain or tropical systems can force delays. Exterior work such as flashing and caulking is often delayed during rain, so plan some buffer days into the schedule.

Final Steps Before Installation

A realistic preparatory schedule looks like this: inspection and measurements six to eight weeks before season start, permits two to four weeks, factory lead time two to six weeks, and installation one to five days. If you live in a high-demand area, or if you need many custom openings, start even earlier — eight to twelve weeks is safer.

Standard-sized vinyl and aluminum impact windows tend to have shorter lead times than curved, arched, or specialty-framed units. Also, ENERGY STAR certification or low-E coatings are common options that rarely add much time, but custom decorative grids or unusual hardware can.

Bundling all openings into a single project reduces repeat mobilization charges and often shortens overall delivery and installation time. Phased replacements require the same steps for each stage, so schedule each with its own clear timeline to avoid overlapping delays.

Confirming permits, insurance, and a clear work plan one week ahead reduces the chance of delays when the crew shows up. Expect the crew to cover temporary protection for interior finishes and a final inspection once install and flashing are complete.

With realistic expectations and early action, you can complete impact window installation well before storms arrive.

Keep a short checklist: site assessment, permitting, factory order, installation booking, and built-in buffer time for unexpected issues.
