Window Winterization Solutions

Windows help make your home a comfortable, sunny and beautiful place to be. However, they can leave you vulnerable when it comes to heating and cooling your home. That’s because if you don’t have the right kind of windows, or your windows aren’t properly cared for, they can be the points at which all your heating and air conditioning goes out, and the air from outside comes in.


This means the money you spend to keep your HVAC system running almost literally going out the window.


You might not know what it means to winterize your home – but we are here to help. Read along for window winterization facts and solutions to common window winter woes.

  1. Give all the windows a thorough once over to see how well they insulate your home.

    1.Check your Home for Drafts

    Give all the windows a thorough once over to see how well they insulate your home. On a windy day, go around your home and check to see how much air is getting inside. Check around the seals to make sure nothing is cracking or peeling. Check for signs of water damage, mold and mildew.

  2. 2.Replace Old and Drafty Windows

    Most experts agree that older windows are not as good at insulating your home as newer models. If the windows in your home are very old, you may want to consider replacing them with more energy efficient models. Many times, the money spent buying and installing the windows is nothing when homeowners consider how much money they end up saving in home heating and air conditioning.

  3. 3.Caulking and Sealing

    One easy and effective way to help seal out cold winter air is by giving the area around your windows a fresh dose of caulking. Caulking doesn’t cost a lot, and it’s an easy project you can do yourself over the course of a weekend (depending on how many windows need it, of course). You can also opt to use weather sealing around the edges of your windows to help ensure that cold air stays out. Some homeowners even opt to coat their windows in plastic sheets to be absolutely sure that they are sealed.

  5. 4.Bring in a Professional

    When it comes to winterizing your windows, you don’t have to go it alone. You have a few options if you’d like to seek professional input. For one, you could hire a home energy auditor. These professionals have special tools and techniques to help them evaluate how energy efficient your home is. You can contact your utility company to see if they offer this service. You can also use to find trusted professionals in your area. You might also want to consider a consultation with a window instillation expert. They can walk you through the many, many window options on the market and help you find one that will cut down your heating costs and stay within your budget.


    There are few less welcome surprises than an extremely high utility bill. Don’t be caught by surprise this winter, be prepared! It’s the best way to keep your money in your pocket and your warm air inside your home.
