How to Stop Air Leak - Top of Door

[iherald]

I had my energy audit done not too long ago/ One thing the auditor noticed was the back door of my house isn't hung plumb, and therefore the top portion (opposite the hinges) is a little low and there is an air leak. In an attempt to stop me from having to rehang the door (the door is in my tenant's apartment, and I'm not super handy), what can I do to try and plug the leak but keep the door in use?

Go to Home Hardware or any similar place. You can find many different door gap seals and mouldings.

A draft stopper will do the trick
