Chimney caps are the first line of defense for your venting systems. They act as animal guards, spark arrestors, rain covers, and wind inhibitors. Without a cap on your chimney the flue of your venting system is wide open to the elements. This allows water, animals, and many forms of debris to enter the venting system which will either cause damage or block the venting passageway. At A-1 Safety Chimney Service, Inc. we carry a wide variety of chimney caps. Give us a call today to have a chimney cap installed (630)827-0600.
