Repair or Reline?
Many masonry chimneys are lined with clay flue tiles. Over time, or after a chimney fire, those tiles can crack and the mortar joints between them can open up. A full reline isn’t always the only fix — in the right conditions, gaps and cracks in a clay-tile flue can be repaired in place. AM Chimney Sweep uses genuine HeatShield to repair chimney flues for homeowners throughout New Jersey.

What Goes Wrong in a Clay-Tile Flue
- Open or missing mortar joints between tiles, from age, settling or poor original installation
- Cracked tiles, often caused by rapid heating during a chimney fire, or by moisture and freeze-thaw
- Flaking or spalled tile surfaces from long-term exposure to moisture and combustion by-products
Why It Matters: Gaps like these can let heat, smoke and combustion gases reach the surrounding masonry, instead of staying inside the flue.

Chimney Flue Repair
Repair or Reline?
- The existing flue is the right size for the fireplace or appliance it serves
- The damage is limited to joint gaps, cracks or surface deterioration
- The chimney structure around the flue is sound
A new liner is usually better when: tiles are badly broken or missing in large sections, or the flue is the wrong size for a new or existing appliance.
Tip: We will tell you which situation you are in and why. See documented chimney projects in Our Work.
Why the Flue's Condition Matters
- The flue liner is what keeps heat and exhaust inside the chimney
- Its condition matters whether the flue vents an open fireplace or a furnace, boiler or water heater
- NFPA 211 recommends chimneys be inspected at least once a year
Note: An annual inspection is one way gaps or cracks in flue tiles get caught early, before the next heating season.
FAQ
Frequently Asked Questions
Chimney Flue Repair
It depends on the chimney. In some cases repairing the existing flue is the less disruptive option; in others a new liner makes more sense. We will explain both when both apply. Local guides: Ridgewood and Maplewood, or see all North Jersey towns.
No. Severe damage, missing sections, or a flue that is the wrong size for the appliance usually calls for a new liner.
