Winterizing your doors and windows in the gta

Winter is coming! More than just a catchy phrase from a hit TV show, it’s a reminder for homeowners to take on some basic maintenance and updates. And while cold days can seem very far away when the sun is out and the temperatures are pushing 30, it’s good to be prepared and have a plan for when the mercury starts dipping.

We want to ensure our properties are ready for the cooler months. In particular, you’ll likely need to pay extra attention to your windows and doors to ensure they’re ready when the temperature drops—large glass panes and weakened frames can be a significant source of heat loss.

Check out our guide on taking care of your windows and how to seal your doors for winter. You’ll keep your home warm and cozy through the coldest days.


Learning how to winterize your windows and doors? It can be fairly quick if they’re in good shape.

The first step is to give them a deep clean. This will help reveal any deficiencies in the fixture, by making them easier to spot. You may even notice a draft, crack, or snag during cleaning.

If you didn’t pick up on anything unusual, that’s a good first sign. The next step is to shine a bright flashlight along the edges and surfaces of your windows and doors. Check for spaces, gaps, cracks, or anything else that might be concerning.

If you can’t tell visually, here’s an easy way to find out if you need to give your fixtures a little boost to get them winter ready. Put your dampened hand along the seams and casings of your doors and windows on a cool day.

If you feel a draft, pick up some adhesive weather stripping for a quick fix. Thoroughly clean and dry the areas the weather stripping will go, and firmly apply it against the seams of your doors and windows.

As for how to winterize a front door, check to make sure they’re hanging properly in the frame! If your door hasn’t been opening, closing, or latching well, it may have shifted, creating gaps where air and heat can flow. Retighten the screws and check your door’s hinges. Realigning your door can help maintain the boundary between the inside of your home and the great outdoors.

And if you’re lucky enough to have them, here’s how to winterize your patio doors. Clean and keep the tracks free of debris so they close tightly. In extra cold areas, some homeowners will apply a sheet of adhesive plastic to the window to add an extra layer of insulation. While practical, a more aesthetically pleasing option may be to hang heavy curtains in front of your patio doors to keep the cold out.

If your energy bills are unusually high, it may be time to reapply the caulking around your windows and doors. Caulking lasts around five years before it needs to be redone. While you can apply a new coat over the existing caulking, it’s better to remove what’s there and start fresh.

The same goes for spot application—you may be tempted to just fill in a couple of trouble spots, but it’ll look cleaner and seal better if you remove what’s already there first. Recaulking your exterior openings can make a big difference in your home’s energy efficiency while giving your windows and doors a cleaner look.


For older homes or homes with older windows and doors, consider replacing them altogether, particularly if your fixtures have experienced a seal failure. The spaces between glass panes should be airtight, filled with argon or a similar gas for improved insulation.

When the seal has been compromised, the gas leaks out, reducing your window’s insulative properties and leaving them susceptible to condensation, mold and mildew.

While you could replace the glass with an after-market product, this can be a costly short-term fix. Older windows are made from outdated technology and tend to be less energy efficient. Swapping them out for new, state-of-the-art windows with proven energy efficiency, improved functionality, and updated styling is likely the better bet.
