Here you'll find what to look for and the tools you’ll need for the inspection.
Project step-by-step (8)
Glass & Screen
- Check the glass doors for cracks or defects, assuring they operate smoothly and are clear of soot.
- Be sure spark screens move in their track smoothly and are tangle-free.
- The hearth includes the floor of the fireplace and the area in front of the fireplace.
- The hearth should be made of non-flammable material and should extend a minimum of 16 inches from the front of the fireplace out to any combustible material (carpet, wood floor, etc.).
- Clean out the ashtray and vacuum the hearth.
- Inspect the firebrick for cracks and defects on the floor of the hearth and on the walls of the firebox.
- Be sure your fireplace has a grate for the logs to sit on.
- Proper airflow around the logs will enable the logs to burn efficiently.
- Creosote is the black tar-like natural byproduct of burning wood.
- Creosote can build up inside the flue, on the damper or inside the firebox, causing chimney fires.
- Use a mirror and light to inspect the damper door located just above the firebox. Be sure it opens easily and closes completely.
- Look for creosote buildup.
- The flue is the passageway in a chimney that conveys flame and smoke to the outer air.
- A flue liner protects the inside of the chimney from collecting creosote. It has a smooth, easy-to-clean surface, enabling the fire to draft properly.
- Again, use a mirror and light to inspect the chimney flue for any creosote buildup or defects. If available, use a snake inspection camera to get a closer look down the flue.
If no flue is present, do not use the fireplace! Stop and get advice from an expert.
The Chimney Structure
- Go outside and inspect the integrity and soundness of the chimney structure. If you’re comfortable, use a ladder to get on top of your roof.
- Look for missing bricks and cracks in the grout between the bricks.
- Make sure the flashing around the chimney is intact and installed properly.
- Be sure the chimney cap and grate are clear of debris.
- Look for black residue between the chimney bricks.
- Note: This means creosote could be seeping through.
- Look to see if your chimney sways or has a bow
- Note: This means it could be structurally unstable.
Be on the Safe Side
- Replace batteries in carbon monoxide and smoke detectors.
- Be sure your fire extinguishers are fully charged and easily accessible.
