Winterizing Your Windows: Everything You Need to Know
Failing to winterize your windows could mean feeling your home’s temperature plummet even as your energy bills climb ever higher. Luckily enough, winterizing windows involves a single two-pronged attack:
Caulk the outside of the window
Weather-strip the inside of the window
Easy enough, so let’s find out how it’s done.
Caulking the Outside
There’s probably old caulk and paint to deal with — scrape it away with a stiff-blade putty knife. Next, scrub away dirt and dust using warm, soapy water and then rub dry with a clean cloth.
Now for the caulking itself:
Pick an exterior-grade caulk of either 100% silicone or siliconized acrylic
Move steadily around the window perimeter to create a continuous bead between the window frame and siding
Weather-Stripping the Inside
Caulking should always be followed by interior weather-stripping around the sash — the sashes are the moveable parts that open and close the window. You’ll have a few options to choose from, including:
Adhesive-Backed Foam: Compresses to seal gaps when the window is closed. Easy peel-and-stick backing makes for relatively effortless application, but you should ensure the area is completely clean.
Tubular Rubber-Gasket: Similar to adhesive-backed foam, but forms into a hollow rubber tube. Some adhere, but many must be fixed using nails or screws. Look for a sponge-foam core.
Spring V-Seal: Made from resilient polypropylene plastic or a metal strip, it gets its name by generating tension between the sash and window frame. Plastic comes with peel-and-stick; metal must be nailed into place.
Felt: The traditional option, felt is affordable and simple to install, but it doesn’t last quite as long as other weather-stripping options — expect to replace it every two to four years.
Insulation Kits: Creates a seal using a large sheet of shrink-wrap plastic. It’s very effective, but you’ll need to peel the wrap away when you want to open the window come spring.
