Winter
Reduce Drafts Before the First Freeze
Check the storm window fit, confirm the top and sides are sealed, clear the sill weeps, and make sure the glass panel closes cleanly. The goal is a stable insulating air space over the original glass.
Seasonal Storm Window Guide
Prepare custom storm windows for winter drafts, hurricane-season rain, tornado watches, hail, and wind-driven weather without overstating what a storm window is built to do.
What Changes by Season?
The same exterior storm window may be asked to reduce heat loss in January, shed wind-driven rain in April, stay secure through summer storms, and protect older wood sash from repeated exposure all year.
Winter
Air sealing, panel closure, condensation drainage.
Storm Season
Mounting checks, glass condition, local safety rules.
After Storms
Inspect glass, frame alignment, drainage, and hardware.
Prepare by Season
Spring Storms
Control Wind-Driven Rain and Pollen
Inspect caulk joints, clean tracks, wash screens, and look for loose corners after freeze-thaw cycles. Exterior storm windows help shield older sash from repeated wetting and debris.
Hurricane Season
Plan Around Local Code and Impact Exposure
Storm windows can help protect existing windows from everyday weather, but standard units are not a substitute for impact-rated windows, shutters, or emergency boarding required in hurricane zones.
Tornado Watches
Treat Windows as a Risk Area
During a tornado warning, move to a basement or interior room away from windows. Storm windows are not tornado protection and should never replace emergency shelter guidance.
Seasonal Checklist
Use this as a practical maintenance rhythm for exterior storm windows, especially on older homes, historic sash, rentals, and multi-window projects.
Before Cold Weather
- Measure problem openings
- Replace missing fasteners
- Clean tracks and sill weeps
- Confirm each panel locks or closes fully
Before Severe Storms
- Inspect exterior mounting points
- Remove loose yard debris near windows
- Confirm local hurricane or storm-prep requirements
- Photograph older windows for insurance records
After Winter
- Check for cracked glass
- Look for bent frames or loose corners
- Clear blocked drainage openings
- Re-measure any opening that shifted or swelled
What Storm Windows Can and Cannot Do
Custom storm windows can improve comfort, reduce drafts, help protect existing windows from weather exposure, and support seasonal ventilation when the unit includes screens.
They should not be described as hurricane-proof or tornado-proof unless a specific product is tested, listed, and installed for that code requirement. In severe weather, follow local emergency management guidance first.
Frequently Asked Questions
Are Storm Windows Good for Winter?+
Yes. A well-fit storm window helps reduce drafts and creates an insulating air space over the existing glass, which can improve comfort in older homes during cold weather.
Do Storm Windows Protect Against Hurricanes?+
Standard storm windows are not a substitute for impact-rated hurricane windows, storm shutters, or plywood required by local code. They can help with everyday weather exposure, but hurricane preparation should follow local emergency guidance.
Will Storm Windows Protect a Home During a Tornado?+
No window should be treated as tornado protection. During a tornado warning, move to a basement, storm shelter, or interior room away from windows.
Should Storm Window Weep Holes Stay Open in Winter?+
Yes. The sill weeps should remain clear so condensation or wind-driven moisture can drain. Seal the top and sides, but do not seal the drainage path shut.
When Should Storm Windows Be Inspected?+
Inspect them before winter, before hurricane or severe-storm season, and after major wind, hail, or heavy-rain events. Look for broken glass, loose hardware, blocked weeps, and frame damage.
