The flue liner — clay tile in most older masonry chimneys, metal in many others — keeps heat and combustion gases inside the flue and away from the surrounding masonry and framing. Cracked tiles, open joints or gaps compromise that. Whether a liner can be repaired or should be relined depends on the material, the extent of the damage and the appliance it serves. We evaluate it with a camera scan first, because you can't judge a liner you haven't actually looked inside.
What homeowners notice
- An inspection or camera scan flagged cracked or displaced liner tiles
- Pieces of clay tile appearing in the firebox
- Draft, odor or staining problems with no surface explanation
- A liner in an older chimney that's never been evaluated
How we diagnose it
- A camera scan of the flue to see the liner's actual condition along its length
- Identifying the liner material and how it's failing
- Judging whether damage is localized and repairable or widespread
- Confirming the liner suits the appliance connected to it
Your options — and their limits
Localized repair
Where damage is limited and the liner type allows, targeted repair methods can restore it.
Reline instead
When damage is extensive or the liner is unsuitable, relining is the sounder path — we'll explain why rather than over-repairing.
What affects the price
We don't post flat prices, because an honest number depends on what we actually find. These are the factors that move it:
- Liner material and how it fails
- Extent and location of the damage
- Chimney height and access
- Whether repair or relining is the appropriate route
When to stop using the system and get it evaluated
- The scan shows cracks or gaps in the liner — stop using the system until it's addressed
- There are signs of a past chimney fire, which commonly damages liners
How to prepare for the visit
- Have any prior inspection or scan footage available
- Let the flue cool before we scan it

Questions homeowners ask
Can a cracked liner always be repaired?
Not always. It depends on the material and how much is damaged. Some liners are best repaired; others are past that point and should be relined. The camera scan is what tells us which.
Why does the liner matter so much?
It's what keeps heat and combustion gases contained within the flue. A breach can let them reach masonry, framing or living space — which is why liner condition is a safety question, not a cosmetic one.
