How to Seal Windows and Doors for Winter

With winter right around the corner, it’s a good idea to start thinking about ways to save money on your heating bill. While many new homes have been built recently, most homes share a common issue that can result in higher energy bills. Drafty windows and doors are often responsible for a big waste of money.

When your home was built, the windows and doors were most likely sealed. However as the home ages, the sealant used on the windows and doors also ages and develops cracks that allow a draft. Those cracks can become larger each year and have a negative effect on your energy bill. So, before winter gets here, it’s a good idea to inspect your windows and doors and see if they need repairing.

Inspection of doors and windows doesn’t have to be hard, it’s just a matter of looking in the right place. For example, on your windows, look at the outside edge of the window frame. You may be able to see the caulking or sealant that was used during installation. If you can see visible cracks, it’s time to repair the seal.

If you aren’t afraid to get a little dirty, you can easily do the job yourself. You will need a caulk or sealant removal tool that can be found at home improvement stores. If you can remove a small piece of the existing sealant, take it with you to the store. An associate should be able to help you find the right product you will need during the repair.

Remove the old caulking with the removal tool from around the door or window frame. You may notice how important the seal is because there may be a large gap between the frame and the exterior of the house. Apply the new sealant to the window or door frame and allow it to dry according to the directions on the product. Inspect it the next day to make sure the project is complete.

It may take some time to perform the maintenance on every window and door on your house. However the project will pay for itself over time as you save money on your energy bills throughout the year.
