In most cases chimney cap/spark arrestors are required by code. Chimney caps prevent sparks from leaving the chimney and possibly landing on the roof or neighbor’s roof. The spark arrestor part of the chimney cap also prevents birds and animals from entering the chimney. Caps also prevent water entering the chimney, Water is the number one leading cause of premature failure of a chimney system.
Dampers can save you money on your energy bills. A properly functioning damper prevents warm/cold air from leaving the house and escaping through the chimney. A “Top Sealing Damper” is the only damper with a 100% seal. This could potentially save the homeowner up to 30% on their energy bills.
