When you try so hard to keep your home hot or cold, depending on the time of year, a window air leak is a first class enemy. Having an air leak is similar to having a hole in your pocket, as your money are spent more and more on keeping a suitable temperature in your house.
Fixing a window air leak is something you don’t need special skills for, just a little knowledge. First of all, you need to find the source of the leaking. If you suspect you have a leak, start testing your windows for one. The easiest way is to hold a candle near a window’s joints and connections. If the fire flickers, you have found your air leak. Make sure you check:
the frame meeting the wall
the window meeting the frame
where the different sections of the window meet each other
After you have found the leak it’s time to repair it. The main cause of leaks is a breakdown between the frame of the window and the frame of the house. So seal the portion with a polyurethane mix.
Injecting foam sealer between the frame of the window and the frame of the house is also helpful. This is a major obstacle to leaks and will also prevent water from leaking into your house.
Another culprit might be the weatherstripping. If it wears out, it will most likely cause air leaks. Try to figure out if this is the cause and then replace the weatherstripping in question. Your local hardware store should provide you a vast range of choices.
In conclusion, fixing a window leak should be a easy task. Discover the source of the problem and address it properly, and you won’t have to suffer anymore.
