  • Chimney size and accessibility – Labor costs increase for chimney crowns that are larger, difficult to access, or above a steeply sloped roof.

  • Other repairs – Minor chimney repairs cost $200 to $700 to fix cracks, flashing, cracked flue tiles, or mortar. More extensive repairs include replacing the flue liner for $900 to $7,000. Consider combining these repairs with crown repair or replacement in the same visit to reduce labor costs.

  • Permits – Chimney crown repair typically does not require a permit. However, some cities may require a permit for replacing the crown, with costs ranging from $20 to $50.

Cost of a new chimney crown

  • Chimney inspector – A chimney inspection costs $360 to $450, with most inspectors charging a flat fee rather than an hourly rate. Hire a chimney inspector before replacing the crown to determine if the chimney needs other repairs at the same time.

  • DIY – While not recommended for major structural issues, using brushable paint to seal small cracks yourself can eliminate the need to pay a professional. Brushable repair paint costs $75 to $125 per gallon.
