Chimney repairs FAQs

Chimney repairs can take many forms for a seemingly simple structure, and costs can vary widely. Common chimney repairs include:

Chimney flashing repair: $150–$500
Repointing mortar joints: $400–$2,500
Repair or replacement of flue liners: $200–$7,000
Patching brick or stone: $350–$3,000
Pouring a new concrete top: $100–$3,000
Repairing chimney caps: $75–$1,000

The cost to replace the chimney crown or top is about $1,550 on average. The range varies widely depending on the size of the chimney, the materials used, accessibility, and the extent of the damage. If you suspect a problem with your chimney top, call a professional masonry contractor for an inspection.

Some of the most common chimney problems include:

Creosote buildup
Chimney blockage
Deteriorating brickwork or stonework
Cracked chimney top
Damaged flashing
Flue liner damage or deterioration
Damaged chimney cap

If you suspect you have a chimney problem, contact a masonry contractor for an inspection.

On average, chimney repairs cost about $455. However, because of the vast range of potential repairs needed, the cost to repair a chimney ranges widely from $160 to $15,000, depending on the type and extent of repairs required.

The cost to replace a chimney is about $10,000 on average and can cost up to $15,000, depending on the size, accessibility, materials, and extent of the replacement. Sometimes tearing the chimney down to the roof line and rebuilding it is an option. But if the chimney's internal structure deteriorates badly enough, a complete demolition down to the fireplace or the foundation may be necessary.
