How to Find the Cause of Drafty Windows

There is a point every South Portland winter when you can’t seem to find the root of the draft in your home. It could possibly be originating from a window that isn’t closed or sealed correctly. Even the thinnest of cracks can make homes uncomfortable and chilly, potentially resulting in:

  • Cold air leaking into your home
  • Larger heating and cooling costs

As per the Environmental Protection Agency’s Energy Star program, you can save 10 percent on your monthly energy bill, or 20 percent of your heating and cooling costs, with correctly sealed windows. To help cut back and reduce drafty air from passing through your home, it’s essential to be able to recognize where these window drafts may be originating from and why. Here are some useful tips to pinpoint your South Portland home’s drafts and check for issues:

  1. Examine for gaps and breaks in unusual points of air leakage, such as knee walls, outdoor faucets, attic hatches or just the normal windows with operable abilities and use a straightforward visual inspection.
  2. Inspect to ensure that windows and doors are sealed and latched.
  3. Make sure that the sealant or gasket around the operable portion of the window or door is properly sealing.
  4. Check the installation by establishing if the draft is passing through the window or around the window, between the window and the harsh opening. A window will only operate as well as it is installed.
  5. Call an expert from Pella Windows and Doors in South Portland to have them conduct a home energy audit.

Once you’ve identified where the draft or air leakage is coming from, the next step is to attend to the foundation of the draft or air leakage. As always, give the specialists in South Portland a call at 207-253-1856 with any additional questions or possible replacement needs.
