Answers:    call a chimney sweep company surrounded by the phone book and have them inspect yours. they would be capable of tell you if it's broken or built incorrectly or what own you. there are spring loaded dampers that can be mounted on the top of a chimney and they enjoy chains that hang down inside the flue so that you can expand and close it. good luck, hope this help.
