Your Guide to sealing drafty windows before winter

By Tom Nonmacher

Winter is coming - and nothing can spoil the cozy atmosphere of your home faster than drafty windows! Not only do they let in cold air, but they also increase your energy bills as your heating system works overtime to compensate for the loss of warmth. Luckily, sealing drafty windows is a budget-friendly, DIY task that can be easily accomplished with a little guidance. Let’s dive into the process and ensure your home is winter-ready.

First things first, you need to identify the drafty windows in your home. On a windy day, hold a lighted candle near the window seams. If the flame flickers or moves, you have a draft. Another trick is to use a piece of lightweight tissue paper. If the paper flutters when held up to the window, you've got a draft.

Next, gather your supplies. You'll need weatherstripping, a window insulation kit, a pair of scissors, a hairdryer, and a caulk gun with caulk. All of these items can be found at your local home improvement store. Make sure to measure your windows before you go shopping so you know how much material to buy.

To start the sealing process, clean the window frames thoroughly. Make sure they're free of dirt and grime, as these can prevent the weatherstripping and caulk from adhering properly. Once the frames are clean, apply the weatherstripping according to the package instructions. This creates a seal that stops cold air from entering through the edges of the window.

After the weatherstripping is in place, it's time to install the window insulation film. Cut the film to the size of your window, leaving a small excess to ensure a tight fit. The film is attached to the window frame with double-sided tape, which is usually included in the window insulation kit. Once the film is attached, use your hairdryer to heat it up. This shrinks the film, creating a tight seal against drafts.

For those windows that are extremely drafty, you might need to use caulk. Apply a thin bead of caulk around the window frame, smoothing it out with a caulk tool or your finger. Be sure to caulk both the interior and exterior of the window for the best results.

Remember, winterizing your windows is a cost-effective way to keep your home warm and cozy throughout the cold months. It's a simple task that can save you a lot of money in energy bills and also increase the comfort level in your home. Remember to check your windows annually and replace the weatherstripping and insulation film as needed.

There you have it - your guide to sealing drafty windows before winter. With a bit of time and effort, you can easily winter-proof your home and enjoy a warm, cozy winter. Remember, it's not just about comfort, but also about saving energy and reducing your carbon footprint. Happy winterizing!
