Why older chimneys are vulnerable
Many Park Hill houses were built with wood-burning fireplaces and brick chimneys, and some original chimneys also vented coal or gas furnaces at one time. Depending on age, a flue may have a clay tile liner, a later metal liner, or in the oldest cases little more than the brick itself.
A chimney fire happens when creosote deposits inside the flue ignite. Some are loud and dramatic; others are slow and go unnoticed. Either way the temperatures inside the flue can be extreme, and clay tile liners can crack, mortar joints can open, and heat can reach wood framing that sits close to the masonry.
Smoke damage from a chimney fire often reaches rooms far from the hearth. Downdrafts and puffback push soot out of the firebox, and a cracked flue can leak smoke into closets and upper rooms beside the chimney. Decorative tile surrounds, mantels and built-ins around older fireplaces collect residue too.
Order of operations
Stop using the fireplace
Do not light another fire, and do not run any appliance that vents into the same chimney until it has been inspected.
Get a camera inspection
A chimney sweep or chimney professional can run a camera down the flue to look for cracked tiles, gaps and damage that cannot be seen from the firebox.
Check the framing around the chimney
Ask for the attic and any accessible framing near the chimney to be checked for heat damage or charring.
Clean rooms after the flue is secured
Soot cleanup in the living room is wasted effort if the flue keeps leaking residue, so plan room cleaning after the chimney is addressed or sealed off.
Decide on chimney repair
Options range from repointing and repairing tiles to installing a new liner or rebuilding the top of the chimney.
Common repair paths
| Option | When it tends to fit | Things to ask |
|---|---|---|
| Tile repair and repointing | Limited cracking near the top or isolated joints | Will the whole flue be verified after repair? |
| Stainless steel liner | Cracked clay liner or no liner | Is it sized for the fireplace or appliance it will serve? |
| Cast-in-place liner | Irregular or damaged flues | How is the work inspected and documented? |
| Partial rebuild above the roof | Spalled or loose brick at the crown | Will the brick and mortar match the original? |
| Decommission and cap | Fireplace will no longer be used | How does this affect home value or future use? |
Common questions
- Does homeowners insurance usually cover a chimney fire?
- Sudden fire damage is commonly covered, while wear and maintenance issues are often excluded. The line between the two can be argued, so read your policy and document the inspection findings.
