Have you ever turned your heat up in the winter and after a little while, had to turn it up even further? If you have areas around your Maryland windows that are letting in cold air, you could be making your heater work harder than it has to. In turn, that means you’re paying more than you should for your heat.

Luckily, there’s a simple way to fix your cold air problem – all you have to do is install some window weatherstripping. Weatherstripping is relatively inexpensive and will form a seal to help keep cold air from coming in.

Step 1

Determine where your window air leaks are. If you can’t do this by simply feeling around the area for a breeze, light a candle and hold it near the area. If it flickers, you have a leak.

Step 2

In order to figure out how much weatherstripping you need, add up the perimeter of all of your windows and add about 10%, just in case of mistakes. (Remember: If you’re measuring single-hung windows, you’ll only need to measure the bottom portion. If you’re measuring double-hung windows, you’ll need to measure all the way around.)

Step 3

After that, determine which type of weatherstripping you want to use. There are many different types, however, felt, foam, vinyl, metal, and rubber are the most common. Which you choose depends on your budget, what kind of windows you’re dressing, and the type of weather in your area.

Felt and foam weatherstripping generally cost the least and are easy to install, but they may not be as effective as others like metal or vinyl. If you’re not sure which to choose, call one of our Maryland window repair experts. We’d be happy to help.

Step 4

After you’ve chosen your weatherstripping, wash the sash with soap and water and let dry. Cut the weather stripping to the correct length, then attach to the bottom of the sash to create a bond (this may mean pealing back the adhesive, stapling the stripping on, etc.). Trim any excess ends so that the stripping is flush with the sash.

Step 5

If you have any large holes or gaps around the outside of your windows, be sure to fill them in with caulk. Holes and gaps are the perfect way for cold air to leak in.

Step 6

You can also go a step further and purchase clear, removable caulk to fill in the thin spaces between your window and the window jambs, head, and sill. This will help seal your windows even more and can be removed once summer comes around again.
