Get matched with top hurricane film pros in Lake Shore, MD

The average cost for window security film is around $7 per square foot or $42 per window. However, your total could range from $3 to $15 per square foot or $18 to $90 per window. The cost depends on the square footage of your window, the thickness and quality of the security film, the number of windows, and the type of windows. 

Hurricane window film costs about $350 for a 75-foot roll, which can cover about 10 average-sized windows. This film can help prevent window shattering during extremely high winds, but it’s not impact-resistant like storm windows.

Your homeowners insurance provider may decrease your premium if you improve the security of your home with window security film. You can contact your insurer to determine whether there will be a change in cost after applying this addition. If there is a decrease in your homeowners insurance premium or deductible, it will likely only be available if your window film is installed by a professional window film installer.

Window security film won’t prevent break-ins or stop your window from shattering from impact during extreme weather like hurricanes or tornadoes. However, applying security film is relatively inexpensive, and it can make breaking into your home significantly harder—often hard enough to deter burglars entirely—and keep your window from shattering on your floor after impact. For these reasons, window security film is often a worthwhile investment that helps protect your property.

Window security film has a few key benefits that make it an enticing home improvement:

• It’s much more affordable than shatterproof windows or hurricane windows.

• It improves your home’s energy efficiency and can save money on heating and cooling bills.

• It makes it harder to break into your home.

• It helps prevent dangerous shattered glass after an impact.

• You can tint it to provide additional protection from the sunlight.

Applying window security film yourself is possible, but we don’t recommend it. This task is simple in theory, but getting the product to sit on your windows evenly and without bubbles underneath is challenging for DIYers who lack the necessary experience and tools. You might save money on labor by applying it yourself, but you might also end up with a film that doesn’t look appealing, prompting you to start over and spend the money on a professional installation anyway. Plus, most window film manufacturers will void your warranty if you install the product yourself.
