Winter will be here very shortly and with it comes cold and ice. This also can be a concern for Edmonton homeowners as condensation on windows in winter can be a big problem. It can cause issues such as increased energy bills as well as issues such as mold and mildew, which can be a problem for those with health issues such as breathing conditions.

What Causes Condensation on Windows in Winter?

Condensation can form on your Edmonton windows anytime there is excessive moisture in the air. This can occur both in the humid days of the summer as well as the bitter cold days of the winter. In the winter, condensation can turn to ice as the temperatures drop severely. The moisture will freeze and from ice crystals.

This can cause both structural and aesthetic issues with your windows frames. Condensation on windows in winter can cause the wood to rot which can then lead to growth of mold and mildew. This can then lead to serious issues if the mold then spreads to other areas of your home.

How to Stop Condensation on Windows in Winter


  • Do not air dry clothes inside your home
  • Put all of your indoor plants in one room and do not over-water them
  • Check all gas appliances for issues. Malfunctions can lead to toxin and water vapors to be released into the air
  • Inspect for plumbing leaks and have them repaired
  • Keep a towel on your windows to absorb excess water build-up
  • Turn your heat up at night to prevent ice from forming
  • Seal your windows and baseboards with caulking or foam sealant
  • Adjust your humidifier accordingly
  • Purchase a dehumidifier if you have issues with excess humidity
  • Turn on your exhaust fans. First, ensure that they are functioning properly
  • Install gasket kits in your switch plates and electrical outlets to prevent air leaks
  • Make sure your carbon monoxide detector is functioning properly. Check and changed the batteries regularly
  • Do not store firewood inside the home


You should also check to see if your windows have any air leaks. If these cannot be repaired with caulking, it could be time to have your windows replaced. Vinyl windows are extremely energy efficient. They can be equipped with double or triple pane windows that have a low-E (low emissivity coating) that can help prevent condensation on windows in winter.

As well, inert gases such as argon or krypton can be inserted between the window panes for added insulation. Not only will this prevent condensation from building up, it can also help you maintain a more comfortable temperature year round in your home. In addition, energy efficient windows can greatly reduce your energy costs.
