The short answer
How Storms Damage Double-Pane Windows
Storms can break double-pane windows in a few ways. Flying branches, hail, or loose roof shingles can strike the glass with enough force to crack or shatter the outer pane. High winds can also bend the window frame, putting stress on the glass and the seal that holds the two panes together.
Another cause is a sudden change in air pressure, which can push the glass outward or inward. Even if the glass does not break, the seal can fail, allowing moisture to seep between the panes. That foggy look between the panes is a sign the window has lost its insulating barrier.
What to Do Right After a Storm
If a window breaks during a storm, your first step is to keep people and pets away from the broken glass. Cover the opening with a tarp or plywood to block rain and wind from entering your home. This also stops debris from blowing inside and reduces the chance of water damage to floors and walls.
After the storm passes, carefully remove loose glass and any debris from the area. Wear thick gloves and shoes with sturdy soles. If water has already entered your home, dry the area as soon as you can. Standing water can soak into drywall and wood, leading to mold and rot if left untreated.
- Use a broom to sweep up small glass shards
- Vacuum the surrounding floor to catch tiny pieces
- Take photos of the damage for your records
- Check the window frame for cracks or bending
- Look for water stains on walls or ceilings nearby
When to Call the Pros
You may be able to handle a small crack with a temporary patch, but a full break usually needs professional attention. Local water damage pros can assess the situation, remove water safely, and dry out affected areas. They can also help with debris removal after a storm, making the area safe for you to move around.
If the storm also brought rain into your home, the pros can extract standing water and set up drying equipment. This helps prevent secondary damage like warped floors or mold growth. For the window itself, you may need a separate window replacement service, but the water damage pros can guide you on what to do first.
Preventing Future Storm Damage
You cannot stop a storm, but you can reduce the risk of window breakage. Trim tree branches that hang near your home, especially those close to windows. Secure loose items in your yard, like patio furniture or potted plants, so they do not become projectiles in high winds.
Consider installing storm shutters or impact-resistant glass if you live in an area prone to severe weather. If you live in Layton, keep a list of emergency contacts and your insurance policy handy. Regular maintenance of window seals and frames can also help them withstand pressure changes better.
- Trim branches that touch or overhang your roof
- Anchor outdoor furniture and decorations
- Check window caulking and seals each season
- Keep a roll of plastic sheeting for quick cover
- Know where your main water shutoff valve is
What About Insurance and Costs
Storm damage to your windows may be covered by your homeowners insurance, but it depends on your policy and the cause of the break. Policies vary, and your insurer decides what is covered. You should check your policy documents and talk to your insurance company about what to do next.
The cost to replace a double-pane window can vary widely. It often depends on the size of the window, the type of glass, and whether the frame also needs repair. A typical range might be a few hundred to over a thousand dollars, but that is just a rough idea. The final price depends on your specific situation and the materials used.

Can a double-pane window break from wind alone?
Yes, but it is less common. Very strong winds can create pressure differences that push on the glass. If the window is old or the frame is weak, the stress can cause cracks. Flying debris is the more usual cause of a break.
What does a broken seal look like?
A broken seal often shows as a foggy or cloudy area between the two panes. You might also see condensation or water droplets trapped inside. This means the insulating gas has leaked out, and the window no longer works properly.
Should I board up a broken window right away?
Yes, covering the opening helps keep rain and debris out. Use plywood or a tarp and secure it tightly. This gives you time to arrange for repairs and prevents further water damage to your home's interior.
