Your home window weatherproofing guide
Weatherproofing enables your home to withstand heavy rains, wind, snow, and extreme temperatures. A good place to start is with your windows since they’re a common place where heat is lost during the year’s cooler months. Read on to learn more about weatherproofing your home’s windows.
Add rope caulk
Start by having your windows cleaned professionally. This is a good way to spot any issues with poor insulation. Next, add rope caulk. It’s a non-hardening, putty-like material used to seal drafty areas around windows. Take as many strands as you need and mold them around the drafty areas of your windows.
Estimated cost: $5.98/90 ft.
Use draft snakes
Draft snakes are good for more than just doors. They can also be used to protect your windows. Simply add them where you need them.
Estimated cost: $10 to $15, depending on whether or not you make your own or buy one.
Air-seal windows with foam tape
Double-sided foam tape provides extra protection against the cold. Modern vinyl window frames often come with a fiber weather seal. However, it becomes compressed over time, allowing drafts inside. Double-sided foam tape is a great way to boost energy efficiency and keep drafts out.
Estimated cost: Less than $3 in most locations across the U.S.
Consider low-E storm windows
Low-emissivity storm windows are windows with a thin, transparent metal coating that reflects heat into a home, improving insulation and reducing energy costs. Storm windows with a low-E glass coating over their exterior could save you as much as 33% off your annual energy bills.
Estimated cost: Somewhere between $60 to $200 a window based on factors such as where you live and what conditions are common.
Use thermal curtains
Thermal curtains insulate windows with multiple layers of fabric. They are a cost-effective way to reduce the heat transfer through your windows. Thermal curtains consist of multiple layers of fabric, including heavy insulating materials. These thick layers of material trap air leaks.
Estimated cost: $38 to $220 if you have larger windows or prefer thicker or commercial thermal curtains if you have a business or an office.
Use honeycomb shades
Cellular shades, also known as honeycomb shades, are a solid and practical choice with a unique honeycomb pattern. They have pockets with air that help block out air from your windows from getting into your interior spaces.
Estimated cost: $34 to $127.63 if you have larger windows or prefer cordless options.
Weatherstrip your windows
Weatherstripping seals gaps around windows. Unlike caulk, weatherstripping still allows windows to open normally. When applied correctly, weatherstripping is a good way to provide insulation to your windows.
Estimated cost: Between $5 to $10 per window with professional installation.
When should you replace windows?
Replacement may be the best long-term solution for windows over 20 years old or ones showing significant damage or wear. If you have single-pane windows and live in a cold climate, look into replacing them.
