How to find window leaks

Finding Door and Window Leaks

One of the quickest ways for your heating bills to skyrocket in the winter is if your home has leaky doors or windows. Once your furnace heats up the air in your home, you don’t want to lose it to the outside. That is exactly what happens if you have leaking doors or windows. If you suspect that your doors or windows may be leaking, here are some ways that you can check to see if you are right.

Use the Tools of the Trade

One option, which might be expensive if you don’t have the equipment on hand, is to use specialized tools to find out if you have a leak. The best way to do this is with an infrared thermometer. This is a device that doesn’t need contact with a surface in order to tell temperature. You can point it at a suspect window or door and actually see where the warmer or cooler areas around them are. It will be very apparent that you have a leak using one of these devices.

Keep Your Eyes Open

If you don’t feel like investing in a quality infrared thermometer, another method you can use is simply to look for evidence that your windows or doors may be in need of repair.

Walk around the outside of your home and inspect the windows. You should be able to see a plain bead of caulking around each of the windows that is used to seal them. If the caulking is starting to peel or crack, then you might have a small leak. Large missing pieces can be causing even larger leaks.

If you have older single pane windows look around the edge of the windows at the glazing. Glazing is a hard putty that is used to hold the panes in place and seals the windows. As these windows age the glazing will crack and crumble. If you see signs of this, then it is a potential sign of a leak.

Open your doors and windows to see if the weather stripping is missing. This can also be a major cause of leaks. If you head inside of the house, you can close the door and see if there is light leaking in from underneath the door. This is an indication that there is a leak.

Using Smoke

You can also do an easy test that involves using smoke from an incense stick. Close up all of the windows and doors in your home. If you have any appliances that use natural gas, turn them off as well; they can throw the test off. Finally, turn on all of the kitchen and bathroom exhausts to create a negative pressure inside of your home.

Take a lit incense stick and hold it near doors and windows. If there is a leak, you will plainly be able to see the smoke drawn into your home.
