Can High Winds Crack My Large Picture Windows?

Large picture windows have a big surface area, so wind pushes against them with significant force. During a storm, gusts can create pressure differences between the inside and outside of your home. That pressure can flex the glass, and if the window is already weakened, it may crack or even shatter.

Flying branches or loose debris can strike the glass directly, causing a point of impact that spreads into a crack. Even if nothing hits the window, strong winds can vibrate the frame, loosening seals over time. A small crack lets moisture in, and that moisture can damage your walls and flooring if left unchecked.

If you notice a crack, act quickly to keep water out. Tape the crack with clear packing tape as a temporary measure, but do not try to replace the glass yourself unless you have experience. A broken window can let in rain and wind, which can soak your carpet, drywall, and belongings.

Your first step is to protect the area from water. Move furniture away, put down towels or a bucket, and if possible, cover the window from the outside with a tarp. Then, contact a window replacement professional to assess the damage and install a new pane or window unit.

The right way to avoid cracked windows is to keep them in good repair. Replace worn weatherstripping and reseal the frame every few years. If you live in an area with frequent storms, consider installing impact-resistant glass or a protective film, though that is a decision for you and a window professional.

Trim trees and branches near your windows to reduce the risk of flying debris. Also, check that your window locks and hinges are tight so the window stays firmly closed during high winds. Regular maintenance now can save you from water damage later.
