Most homeowners weather strip their doors and windows in order to keep the air inside and save energy on heating and air conditioner. But that is not just what weather stripping does: it can also prevent rain and bugs from entering your home. It keeps heat out as well during the summer.

However, the stripping on your door or window can be prone to a series of wear and tear, especially if it is used often. In case of damage, you must get it replaced. When the strips are used on doors or windows to keep out rain, heat, and bugs, it is recommended to check them once a year. This is to avoid later issues that might lead to high repair costs. 

After weather stripping your doors or windows, make sure to inspect them in case of leaks. You can do this with a lighter or flashlight.

If there is a sign of flame or light flickering, then it is time for a replacement.
