Check Window & Door Seals

The seals around your doors and windows can wear out over time allowing cold air to leak into your house and make your home feel drafty. Fortunately, replacing leaking seals is an easy job to do that can save you money on your heating bill.

How to find those leaks:

  • The first thing to do is to look at each seal and look for missing sections in the seal or tears. If you find any of those conditions, the seal must be replaced to eliminate air leaks.
  • For doors, you can look for light between the door and jamb. Light means there is a gap between the door and seal.
  • If you don’t see anything obvious, try holding a lit incense stick or cigarette near the window or door during a windy day. If there is a leak, you’ll see the smoke being blown away or drawn towards the door or window.

What to do:

  • Replacement seals for doors, especially the sweep seal located at the bottom of the door, can often be found at your local hardware store. Sweep seals are height adjustable and can be moved to close the gap.
    • Replacing door seals is a good do it yourself project.
  • Window seals may be available at the local hardware store, but generally you’ll need to visit a glass and window shop to obtain replacement seals.
    • Window seal replacement may require removal of portions of the window assembly and may be best done by a technician.
