How To Winterize A Window

Winterizing windows is an important step for keeping your home warm and ensuring you’re not paying high heating bills during the colder months. Luckily, there are many ways for weatherizing windows that homeowners can take advantage of depending on their home’s needs. The steps for how to weatherproof windows include:

We also provide some maintenance tips for the best way to winterize windows for the long haul.

Assess Your Windows For Winter Readiness

Before starting to winterize windows, it’s important to inspect your windows for any damage or issues that could affect insulation efficiency. You’ll want to ensure no cracks, drafts, or structural issues could cause your windows to let in cold air. If you have cracks or issues with how the windows seal structurally, you may need to look into replacing your windows.

Seal Gaps And Drafts Effectively

After checking that your windows are in good shape, it’s time to start the weatherize windows process. There are various methods for doing this, including:

  • Weatherstripping: Weatherstripping your windows can help reduce the amount of cold air coming in. While many windows have intact weatherstripping, if yours have been damaged in some way, you can buy weatherstripping adhesive tape to fill any gaps.
  • Caulking: Another way to winterize a window is by re-caulking it. This includes a bit more effort, as you’ll have to remove the old caulking before starting the process, but it’s an effective way to protect your home. One thing to keep in mind: you won’t be able to do this in the middle of winter, as most caulk needs weather above 40 degrees to cure properly.
  • Window Kits: Another way for how to seal old windows for winter is by purchasing window insulating kits. These include plastic that is taped to your window. Then, you use a hair dryer to shrink-wrap the plastic to your window. It’s a very easy and cheap way to keep the heat in.

Install Insulating Window Treatments

Another way to get some of the best insulated windows for cold weather is to install insulating window treatments. These curtains are made of a thicker, heavier material than regular drapes, and they effectively retain heat inside your house while also reducing overall energy costs.

Maintenance Tips For Winterized Windows

Once you’ve winterized your windows effectively, it’s important to keep them maintained for long-lasting results. Some maintenance tips for your windows include:

  • Regularly checking for air leaks or drafts
  • Properly cleaning your windows and weatherstripping
  • Ensuring your seal stays intact for optimal insulation

Ensuring the outside of your home is protected against the elements like ice dams is another way to prepare your home for the winter.

How To Winterize A Patio Door

Winterizing patio doors is another efficient way to keep your home warm in the colder months. Depending on how old your doors are and what shape they’re in, there are many ways to winterize a patio door effectively. The steps to follow to insulate doors for winter include:

Evaluate Patio Door Condition For Winter

The first step for how to winterize a sliding patio door is to evaluate if there is any wear and tear and if it is aligned properly. These can both affect how well it protects your home from the cold air. Also, make sure that you check for any drafts.

Weatherproof Techniques For Patio Doors

After evaluating your patio doors, it’s time to weatherproof them. Some techniques for this include:

  • Installing Door Sweeps/Draft Stoppers: This is one of the easiest ways to ensure your doors stay insulated. Door sweeps and draft stoppers slide onto the bottom of your door to block any air from coming in. You can even roll up a towel or blanket if you need an immediate fix.
  • Adding Weatherstripping: You can weatherstrip your doors as well. This may include installing door gaskets or using foam tape to seal any cracks.
  • Upgrade Your Pet Door: For doors with a pet door, it’s important to ensure that you can open and close it effectively during the winter. It may be time to upgrade your pet door if it doesn’t properly latch.

Insulation Solutions For Enhanced Warmth

There are many other ways to add extra insulation to your patio doors for enhanced warmth. For example, you can install thermal drapes like you would for a window, add window insulation film, and even add secondary glazing panels.

Regular Maintenance For Optimal Performance

To ensure long-lasting success for your weatherized patio doors, it’s important to conduct regular maintenance. Every few months, you should clean the door’s tracks, check for drafts, and ensure that your weatherproofing materials remain intact.
