Steps of a Physical Window Checking


Step 1

Make sure all your windows are entirely closed and locked to insure a proper tight seal. Even if you are suspicious about only one window which needs to be checked close all the windows in the room anyway, it will better help you to identify if the problem exists.


Step 2

Check if both your furnace and air conditioner are switched off. After you do it let the remaining air cycle down. There must be no additional air and draft in the room. Minimize the air movement as much as you can. All these suggestions will help you to determine wether your windows leak or not.

As soon as you notice flame flicker this is probably the spot where the window might leak. If the flame remained calm and stable congratulations your window is doing great.
