Winter is here, and it’s cold. Hopefully, you’ve already taken precautions to keep your home safe and warm, but if you haven’t, it’s not too late. With a few small maintenance checks on your doors and windows, you can winterize your home and reduce heating costs. Your doors and windows are important as they are a major cause of heat loss- particularly in homes that were built a long time ago.

Get the Right Equipment

Your safety should be the top priority when engaging in activities around your house. Make sure you’re using the right cleaning equipment when cleaning or servicing your windows, particularly windows that are very high. You need to be cautious when using high-power cleaning equipment, so be sure to read the product manual and follow all directions. Wear goggles and a face mask if possible and make sure your rooms are well ventilated. Wipe spills and stains as soon as they appear and refer to your cleaning product’s instructions for proper disposal.

Check and Clean Your Glass

Get the right glass cleaning product for your window panes. Do not use acidic or abrasive products on your glasses they are capable of destroying the surface of the glass and its frame. Do not wash glass under direct sun rays and do not use power washers to wash glass as this can damage glass as well. If you see little drops of water or fog between glass panes of an insulated glass unit, this may be a sign of seal failure. Always inspect glass panes for cracks or scratches.

Clean the Areas Around Your Glass

Extract dirt and particles stuck in the moving parts of windows, windowsills, and door jambs. Clean up any spots and tighten your window and door seals with caulk if necessary. Check your windows and doors for debris or scratches on the frames. To clean clay, beige, or white PVC frames, use a gentle household cleaner and a soft, slightly wet cloth.

Winterize Your Doors

Inspect the insulating weatherstrip around your doors. Close the door and run your hand along the edge from the inside. This inspection is best performed on a windy day to identify if air is escaping from your house. If you detect any leaks, you can improve the seal by applying weather stripping around your doorframe, applying caulking around your doorframe, or installing a draft guard at the bottom of your door. Also, consider purchasing a storm door. They offer extra protection during harsh winters by acting as secondary barriers.
