How to Tell if Your Impact Windows Are Still Effective After a Storm
Your impact windows just protected your home through a hurricane—but are they still ready for the next one? Knowing how to assess your windows after a storm helps you identify damage that might compromise future protection. Some issues are obvious; others require careful inspection to detect.
Window Guys of Florida provides post-storm inspection and repair services throughout South Florida. This guide helps you assess your impact windows after severe weather.
Why Post-Storm Inspection Matters
Impact Windows Are Designed to Take Hits
Your impact windows performed as designed—they protected your home. But that protection came at a cost:
- Each impact stresses the system: Glass, interlayer, frame, and seals
- Damage may not be visible: Internal stress can weaken components
- Compromised windows: May fail in subsequent storms
- Insurance claims: Document damage promptly
Immediate vs. Long-Term Concerns
- Immediate: Water intrusion, obvious glass damage, security issues
- Long-term: Seal degradation, weakened structural integrity, warranty coverage
Immediate Post-Storm Safety
Before You Inspect
Wait until it's safe:
- Wait for all-clear: Ensure the storm has fully passed
- Watch for hazards: Downed power lines, standing water, debris
- Wear protective gear: Shoes, gloves, safety glasses
- Start exterior inspection: Before entering home if severe damage suspected
Step-by-step guide to inspecting your impact windows for damage after a hurricane or severe storm.
Visual Inspection Steps
Step 1: Exterior Glass Inspection
Examine all glass surfaces from outside:
- Cracks: Any visible cracks, star breaks, or fracture lines
- Chips: Impact points from debris
- Delamination: White/cloudy areas where glass separates from interlayer
- Complete shattering: Severe damage requiring immediate attention
Key point: Impact glass is designed to crack but stay in place. A cracked window has done its job but needs replacement before the next storm.
Step 2: Interior Glass Inspection
Check from inside your home:
- Cracks visible from inside: May indicate deeper damage
- Moisture between panes: Seal failure in insulated units
- Fogging or condensation: Indicates compromised seal
- Discoloration: Water intrusion or interlayer damage
Step 3: Frame Inspection
Examine all frame components:
- Dents or bending: From large debris impacts
- Gaps between frame and wall: Separation from structure
- Cracked or split frames: Structural compromise
- Loose frames: Rattling or movement when touched
Step 4: Seal and Weatherstripping Check
Inspect sealing components:
- Weatherstripping displacement: Pulled away from intended position
- Caulk separation: Gaps at frame-to-wall junction
- Compression seal damage: Flat, torn, or missing sections
Step 5: Operation Test
Test every window for proper function:
- Opens and closes smoothly: No binding or sticking
- Locks engage fully: All locking points operate
- No unusual sounds: Grinding, cracking, or popping
- Proper alignment: Sash sits square in frame
Step 6: Water Intrusion Signs
Look for evidence of water entry:
- Water stains: On walls, floors, or windowsills
- Wet insulation: Check around window frames
- Mold or mildew: May develop days after storm
- Dampness: In drywall near windows
Types of Damage and What They Mean
Glass Damage Categories
| Damage Type | What It Means | Action Required |
|---|---|---|
| Surface scratches | Cosmetic only | Monitor, no immediate action |
| Small chips (dime-sized or less) | May be stable | Professional assessment |
| Cracks (any length) | Structural integrity compromised | Replace before next storm |
| Star break | Impact damage, will spread | Replace soon |
| Delamination | Interlayer separation | Replace - protection compromised |
| Shattered (but held in place) | Did its job protecting home | Replace immediately |
Frame Damage Categories
| Damage Type | What It Means | Action Required |
|---|---|---|
| Minor scratches/scuffs | Cosmetic | Touch-up paint if desired |
| Small dents | Usually cosmetic | Professional assessment |
| Frame bent/warped | Operation and seal affected | Replace window |
| Separation from wall | Structural connection failed | Professional repair |
| Cracked frame | Structural failure | Replace window |
When Professional Inspection Is Needed
Call a Professional If You Notice:
- Any cracks in the glass
- Windows that won't operate properly
- Frame damage or separation
- Evidence of water intrusion
- Fogging between panes that doesn't clear
- Multiple impacts on the same window
What Professionals Check
Expert inspections include:
- Detailed glass integrity assessment
- Frame structural evaluation
- Seal and weatherstripping testing
- Hardware and lock function
- Water intrusion investigation
- Documentation for insurance claims
Insurance Documentation
What to Document
Before cleaning up or making repairs:
- Photograph all damage: Multiple angles, close-ups and wide shots
- Video walkthrough: Document extent of damage
- Note dates and times: When storm occurred, when damage discovered
- List all affected windows: By location
- Get professional assessment: Written documentation of damage
Filing Claims
- Contact your insurer promptly
- Provide documentation and photos
- Request claim number and keep records
- Get repair estimates in writing

Temporary Protection
If Windows Are Compromised
Until repairs are made:
- Board up broken windows: Plywood secured to frame
- Cover cracks: Clear weatherproof tape (temporary only)
- Document everything: Before any temporary repairs
- Schedule replacement: As soon as possible
Maintenance After Storms
Even if no damage is visible:
- Clean all windows: Remove salt and debris
- Lubricate hardware: Salt air causes corrosion
- Check weatherstripping: For displacement or damage
- Test operation: All windows should function smoothly
Follow our complete seasonal maintenance checklist.

Frequently Asked Questions
Is a cracked impact window still providing protection?
A cracked impact window has already served its protective purpose—it stopped debris from entering your home. However, it is no longer reliable for future storms. The glass integrity is compromised, and subsequent impacts may cause the window to fail completely. Replace cracked impact windows before the next hurricane season or approaching storm.
How soon after a storm should I inspect my impact windows?
Perform a visual inspection as soon as it's safe after the storm passes—typically within 24-48 hours. Look for obvious damage like cracks, water intrusion, or operational problems. A more thorough inspection should follow within a week. If you notice any damage, document it immediately with photos for insurance purposes and contact a professional for assessment.
Will my insurance cover storm damage to impact windows?
Storm damage to impact windows is typically covered under the windstorm portion of your homeowners insurance, subject to your deductible. Document all damage thoroughly before making temporary repairs, contact your insurer promptly, and get professional repair estimates in writing. Keep copies of all product specifications and installation documentation, as insurers may require this information.
What does fogging between window panes mean after a storm?
Fogging or condensation between panes of an insulated impact window indicates that the seal between the glass layers has failed. This is often called "blown seal." While the window may still provide impact protection, its insulating value is reduced, and the fogging will not go away. The glass unit (IGU) should be replaced. This damage may be covered by your window warranty or storm insurance.
How many hurricane impacts can impact windows withstand?
Impact windows are tested to withstand multiple impacts in testing scenarios, but real-world performance varies. After any significant impact that leaves visible damage (cracks, chips, delamination), the window should be replaced. Even without visible damage, professional inspection is recommended after a window is struck by debris. There's no guaranteed "number of hits"—each impact compromises structural integrity.
