The damper, located just above the firebox, can open or close the chimney flue. The damper should remain closed unless there’s a fire burning in the fireplace. Closing the damper prevents energy loss through the chimney and cold air from seeping into the home during the winter. Opening the damper helps maintain airflow when there is a fire and prevents smoke and gases from venting into the house.

If your hardwired smoke alarm keeps going off, it could be because the backup battery needs replacing. When replacing the battery doesn’t stop your smoke alarm from beeping, try holding the reset button for 15 to 30 seconds or removing dust from the openings in the alarm. If it continues to chirp, it could be faulty and require replacement.

In addition to flashing, a roof cricket can help divert water around your chimney so that it drains properly off your roof. It’s shaped like a double triangle and is installed behind the chimney so that falling water spills evenly down each side. This helps prevent water from accumulating behind your chimney, which can increase water damage and the risk of leaks. 

The International Building Code (IBC) requires cricket installation if a chimney built after 2012 measures over 30 inches in width. Chimneys constructed before that date are typically grandfathered in and aren’t required to have crickets installed.

Installing a spark arrestor on your home’s chimney is an essential task. It reduces fire risk and ensures your chimney is compliant for insurance and building code purposes. Not having a spark arrestor could invalidate your home insurance or cause snags when it comes to a house sale.
