How to Protect My Windows From Flying Debris?

Last updated October 31, 2026

The short answer

Assess Your Window Vulnerability

Start by checking your windows for existing cracks, loose frames, or gaps. Older windows with single-pane glass are more likely to break under impact. Look at the condition of the caulking and seals around each window, as water can seep in through damaged areas during a storm.

If you live in Quincy, consider the coastal nor'easters that bring strong winds. These storms can send branches and other objects flying. Knowing which windows face the prevailing wind direction helps you prioritize which ones to protect first. For homes with large or older windows, think about upgrading to impact-resistant glass or installing storm shutters.

Install Storm Shutters or Plywood

Storm shutters are one of the most effective ways to shield windows. They can be permanent or removable, and they are designed to withstand high winds. If shutters are not an option, use plywood that is at least 5/8 inch thick, cut to fit each window opening. Pre-cut and label the plywood so you can install it quickly when a storm warning is issued.

Secure the plywood with heavy-duty screws into the window frame or the wall studs. Use brackets or clips to hold the boards in place. Do not nail the plywood into the wall, as that can cause damage. Make sure the boards overlap the window frame by at least 2 inches on each side to provide a solid barrier.

  • Use 5/8-inch exterior-grade plywood for boarding
  • Pre-drill holes and label boards for each window
  • Install with screws into the framing, not the glass
  • Keep a wrench or drill nearby for quick installation
  • Check shutters and hardware for rust or wear before storm season
  • Consider impact-resistant film as an extra layer

Trim Trees and Secure Loose Objects

Flying debris often comes from trees in your yard. Trim branches that hang over your roof or near windows, and remove any dead or weakened limbs. Keep trees healthy with regular pruning to reduce the chance of branches breaking off in high winds.

Also secure outdoor items that could become projectiles, such as patio furniture, grills, and planters. Bring lightweight objects indoors or tie them down. If you have a fence, check that it is stable. Loose gutters or siding can also be torn off and hit windows, so repair any loose exterior parts before a storm.

During a Storm: Stay Away and Close Blinds

When a storm hits, close all windows and doors, and stay in interior rooms away from glass. Draw blinds or curtains to help catch broken glass if a window shatters. Do not open windows to equalize pressure, as that is a myth and can let in wind and water.

If a window does break, avoid touching the glass and keep everyone away from the area. Water may be entering, so move valuables to a safe spot. After the storm passes, assess the damage carefully. Wear gloves and sturdy shoes when cleaning up broken glass.

After the Storm: Check for Water Damage

After the storm, inspect each window for cracks, gaps, or water stains on the walls or ceiling nearby. Even a small crack can let in moisture, leading to mold or structural issues. If you see water damage, it is important to address it soon to prevent further problems.

For water damage, local water damage pros can help with inspection and cleanup. They can identify hidden moisture and take steps to dry out affected areas. If you need window replacement, a qualified contractor can handle that. Check with your insurance company about coverage, and remember that policies vary, and your insurer decides what is covered.

  • Look for cracked glass, broken seals, or warped frames
  • Check window sills and walls for dampness or staining
  • Take photos of any damage for your records
  • Contact a water damage inspection service if you suspect leaks
  • Dry wet areas quickly to reduce mold risk

Frequently asked questions

What type of glass is right for storm protection?

Impact-resistant glass, such as laminated or tempered glass, is stronger than standard glass. Laminated glass has a plastic layer that holds it together if it breaks. Tempered glass shatters into small pieces, reducing injury risk. Check with a window professional to see what fits your home and storm risk.

Can I use plywood for every window?

Plywood can protect most windows, but it is not ideal for very large or oddly shaped windows. It may also be heavy to install. For large windows, consider storm shutters or impact-resistant film. Always ensure the plywood is securely fastened to the framing, not just the glass.

What should I do if a window breaks during a storm?

Stay away from the broken window and keep others away. Close the door to the room if possible to limit water entry. After the storm, carefully remove glass while wearing gloves. Cover the opening with plastic or plywood to keep out rain, then contact a professional for repairs.
