How to Winterize Windows & Keep the Cold Out

Drafty windows can lead to uncomfortable chills, higher energy bills, and even damage to your home’s interior. Thankfully, winterizing your windows is a cost-effective way to keep your home warm and comfortable all winter long.

In this guide, we will explore the best ways to winterize your windows, the benefits of winterizing, and how to ensure your windows are ready to withstand even the harshest winter conditions.

Why Winterizing Windows Matters?

Winterizing your windows is crucial for keeping your home warm and comfortable during cold weather. Here’s why it matters:

• Reduce energy bills: Drafty windows lead to significant heat loss, driving up your energy bills. Winterizing helps seal those leaks, reducing the amount of heat escaping and saving you money on heating costs.
• Prevent cold drafts: Nothing ruins a cozy night like a chilly draft coming from your windows. Winterizing your windows creates a more comfortable living environment by eliminating those uncomfortable cold drafts.
• Protect your home: Cold air can cause condensation on windows, leading to mold growth and damage to your walls, floors, and furniture. Winterizing helps prevent these problems by creating an airtight seal that keeps the cold air out.
• Increase energy efficiency: By creating an airtight seal and adding insulation, winterizing your windows improves your home’s overall energy efficiency, reducing your reliance on heating systems and contributing to a more sustainable lifestyle.

Common Methods for Winterizing Windows

Here are some of the most effective and popular methods for winterizing your windows:

1. Weatherstripping

Weatherstripping is a cost-effective and easy way to seal gaps around your window frames. It’s a simple DIY project that can make a big difference in reducing drafts.

• Types of weatherstripping: There are several types of weatherstripping available, including spray foam insulation, vinyl, and brush strips.
• Installation: Most weatherstripping is easy to install using adhesive or a few simple tools. Follow the manufacturer’s instructions for the best results.
• Common areas: Focus on areas where cold air is most likely to leak in, such as around the window sashes, frame edges, and where the window meets the wall.

By carefully applying weatherstripping around your window frame, you can significantly reduce drafts and create a warmer, more comfortable home this winter.

2. Caulking

Caulking is another essential part of winterizing windows. It helps seal cracks and gaps in your window frames, preventing drafts and moisture infiltration.

• Types of caulking: Silicone and latex caulk are popular choices for window frames. They offer good flexibility and adhesion.
• Preparation: Before applying caulk, ensure the area is clean and dry. Use a putty knife to remove any old or cracked caulk.
• Application: Apply the caulk in a smooth, continuous bead, pressing it firmly into the gaps. Smooth the bead with a damp finger or putty knife.

Re-caulk your windows every year, especially if you live in a region with extreme temperature fluctuations.

3. Storm Windows

Storm windows are a more permanent solution for winterizing your windows. They create a double-pane system that significantly reduces heat loss and drafts.

• Types of storm windows: Storm windows come in various styles, including exterior storm windows that attach to the outside of your existing windows and interior storm windows that attach to the inside.
• Benefits: Storm windows provide excellent insulation and can dramatically reduce heat loss. They also add an extra layer of protection against weather elements.
• Installation: Professional installation is recommended for exterior storm windows. It’s generally easier to install interior windows yourself, following the manufacturer’s instructions.

4. Plastic Film

Plastic film is a budget-friendly option for winterizing your windows, particularly for older windows with single-pane glass.

• Types of plastic film: There are many types of plastic film available, including clear, tinted, and insulated varieties.
• Installation: Apply plastic film to the inside of your windows using double-sided tape or a special kit. Follow the instructions carefully to ensure an airtight seal.
• Benefits: Plastic film significantly reduces drafts and heat loss. It’s a temporary solution that can be removed in the spring.

5. Additional Insulation

Adding insulation to your windows is a more permanent solution for improving energy efficiency and reducing drafts.

• Insulating windows: If you’re planning a window replacement, consider investing in triple- or double-pane windows, which offer superior insulation and energy efficiency.
• Use thermal curtains or blinds: Thick curtains or blinds help trap warm air and prevent drafts from entering your home.
• Install cellular shades: Cellular shades offer excellent insulation and can significantly reduce heat loss.

Professional Winterizing Windows​ vs DIY

When it comes to winterizing your windows, you have a choice: tackle it yourself or call in a professional. Let’s break down the advantages and disadvantages of each approach to help you decide what’s best for your home.

Ultimately, everything comes down to your individual needs and circumstances. DIY matters if you have the time and skills to complete the tasks correctly and are on a tight budget while hiring a professional is a good option if you don’t have the time or skills to do the work yourself, want a guarantee that the job will be done correctly and feel comfortable with the added cost.

Tips to Winterize Windows

To truly maximize your home’s warmth and energy efficiency this winter, it’s important to pay attention to detail. Here are some additional tips for winterizing your windows:

• Check for air leaks: Use a lit candle or incense stick to check for air leaks around your window frames. Watch for any movement in the flame to indicate a draft.
• Clean your windows: Regularly cleaning your windows can help prevent condensation and improve insulation.
• Inspect your window glass: Check for any broken glass or cracks. Repair or replace any damaged glass panes.
• Consider a draft stopper: Place a draft stopper under doors to prevent cold air from entering your home.
