- Chimney cap: Make sure the chimney cap is present and in good repair. The chimney cap prevents hot embers from landing on your roof and keeps out weather elements and animals.
- Damper: Check that the damper opens and closes easily. You can use a dollar bill to test if the damper creates an adequate seal by placing it between the damper doors and then closing them.
- Creosote buildup: A certified chimney sweep can determine the amount of creosote buildup in your chimney. Creosote is a black, tar-like substance.
- Cracks and missing pieces: Check for cracks or missing pieces in the masonry of the chimney.
- Firebox: Check for cracks, stains, or scorch marks in the firebox.
- Water stains: Check for water stains in or around the fireplace.
- Airflow: Check for any blockages or obstructions that could hinder proper airflow.
- Structural damage: Check for clear signs of structural damage.
- Holes in the firebox: Ensure that there are not holes in the firebox.
You can also perform a quick visual inspection by shining a flashlight up the chimney.
For a more thorough inspection, you can hire a chimney sweep. They can use a camera attached to flexible rods to look inside the chimney, specifically the flue liner.
