Average Chimney Repair Costs in 2025

The cost to repair a chimney in 2025 typically ranges between $300 and $3,500. Minor jobs such as tuckpointing or cap replacement may cost just a few hundred dollars, while major structural rebuilds, crown reconstruction, or installing a new liner can exceed $5,000+ depending on size, access, and materials. Our Chimney Repair Cost Calculator above helps you get a realistic, location-adjusted estimate with low, mid, and high ranges.

Here�s a quick look at national averages:

• Minor chimney repairs (tuckpointing, sealant, small cracks): $200 � $800
• Medium repairs (crown repair, flashing, moderate brick replacement): $800 � $2,500
• Major repairs (liner installation, partial rebuilds, major masonry work): $2,500 � $7,000+

Key Factors That Influence Chimney Repair Cost

No two chimneys are the same. Your repair bill depends on several variables:

1. Chimney Type

Masonry chimneys with brick and mortar typically require tuckpointing, crown work, and sealing. Prefab or metal chimneys often need chase covers, flashing, or liner replacements. Masonry tends to cost more because it involves labor-intensive masonry skills.

2. Chimney Height & Roof Access

A 1-story chimney with easy access costs far less than a 3-story chimney on a steep-pitched roof requiring scaffolding. The calculator automatically applies height and pitch multipliers.

3. Extent of Damage

Minor cracks can be sealed for under $300, but major structural damage, missing bricks, or collapsed crowns can multiply costs. Our tool adjusts with Minor, Moderate, and Major damage settings.

4. Regional Labor Costs

Urban areas like New York, Chicago, or San Francisco run 20�30% higher than suburban or rural areas. The calculator uses regional cost factors to reflect real-world pricing.

5. Materials & Finishes

Economy mortar, standard sealants, and galvanized steel are cheaper options. Premium materials like stainless steel liners, high-grade sealants, and custom crowns can push estimates higher but often last longer.

Common Chimney Repairs & Price Ranges

Tuckpointing

Grinding and replacing deteriorated mortar between bricks. Typically $18 � $30 per linear foot.

Brick Replacement

Damaged or spalled bricks are swapped with new ones. Usually $22 � $38 per brick, plus labor for scaffolding if high up.

Crown Repair or Rebuild

Patching cracks with sealant: $250 � $600. Full rebuild or new concrete pour: $700 � $1,500+.

Flashing Repair or Replacement

Flashing prevents leaks where the chimney meets the roof. Repairs: $300 � $600. Replacement: $600 � $1,500.

Chimney Liners

Stainless steel flex liners: $45 � $85 per foot. Cast-in-place liners: $80 � $120 per foot. A typical 20-ft liner may cost $1,500 � $3,000 installed.

Chimney Caps

Basic galvanized cap: $60 � $150 per flue. Premium stainless cap: $160 � $350 per flue.

Waterproofing

Applying professional sealant to the exterior: $200 � $450.

Smoke Chamber Parging

Smoothing rough surfaces with refractory mortar: $300 � $900.

Animal Removal

If birds, raccoons, or squirrels have entered the flue: $150 � $350 including sanitization.

Signs You Need Chimney Repair

• Cracked or crumbling mortar joints
• Spalled bricks (faces flaking off)
• Water leaks near the chimney
• Rust on damper or firebox
• Smoke backup or draft issues
• Missing or damaged chimney cap
• Pieces of flue tile in the firebox

Ignoring these warning signs can turn a $500 fix into a $5,000 rebuild.

DIY vs Professional Chimney Repairs

Some homeowners attempt DIY tuckpointing, waterproofing, or cap installation. While minor tasks may be safe for experienced DIYers, major chimney work requires expertise. Climbing roofs is dangerous, and improper repairs can cause carbon monoxide leaks or house fires. Always hire a certified chimney sweep or mason for structural work.
