How to Fix Air Leaks Around Windows and Doors


Losing heat during the winter is definitely not something we want here in Kenai or Soldotna. Sealing your air leaks around your windows and doors can help lower your heating cost and ensure that you and your family stay warm throughout our harsh winters.

First you need to check to see if you have any leaks! A great tip on how to check is by lighting incense and holding it up to your window or door where the air leaks might sneak in. If you see any movement of the smoke take note of where that leak is before moving on to the next.

If you have older windows, the best way to tighten them up is by caulking and weather stripping them. Here are some helpful tools you can use to help seal your windows.

-Bronze weather stripping ($12 for 17 feet) lasts for decades but is time-consuming to install.

-Self-stick plastic types are easy to put on but don’t last very long.

-Adhesive-backed EPDM rubber ($8 for 10 feet) is a good compromise, rated to last at least 10 years.

You can check for air leaks around doors the same as with a window, so if you notice a leak make sure to replace the weather stripping with some new!

-Foam-type tape has an adhesive backing; it’s inexpensive and easy to install. If it comes loose, reinforce it with staples.

-Felt is either adhesive-backed or comes with flexible metal reinforcement. It must be tacked or glued into place. It’s cheap and easy to install, but it has low durability.

-Tubular rubber, vinyl, and silicone weather stripping is relatively expensive and tricky to install, but it provides an excellent seal. Some types come with a flange designed to fit into pre-cut grooves in the jambs of newer doors; check your existing weather stripping and replace with a similar style. HE6SJ4JRAQTU
