Your Chimney Crown is Its First Line of Defense

The chimney crown is the concrete cap on top of your masonry chimney. It sheds water away from the flue and protects the brick and mortar below. When it cracks — and in Chicago, they all crack eventually — water enters the chimney structure and accelerates deterioration through freeze-thaw cycles.

Crown Repair Cost in Chicago

Crown resurfacing with a flexible crown coat sealant starts at $400. Full crown replacement (removing old, pouring new with proper overhang and drip edge) runs $800–$1,500. The cost depends on chimney size, accessibility, and damage severity. Fixing a crown early saves thousands in brick and mortar repairs later.

We use ChimneySaver CrownCoat for resurfacing (15-year warranty, flexible, waterproof) and pour new crowns with proper Portland cement mixes, steel reinforcement, and a minimum 2-inch overhang with drip edge — the way they should have been built originally.

Frequently Asked Questions

How much does chimney crown repair cost in Chicago?
Chimney crown repair in Chicago costs $400-$1,500. Simple resurfacing with crown coat sealant averages $400. Crown replacement (removing old, pouring new) runs $800-$1,500 depending on chimney size and access.
What does a chimney crown do?
The chimney crown is the concrete cap on top of your masonry chimney. It sheds water away from the flue and protects the brick and mortar below from water damage. It's your chimney's first line of defense against weather.
Is a cracked chimney crown dangerous?
Yes. Cracks allow water into the chimney structure. In Chicago's climate, water freezes and expands inside cracks, causing progressive damage that can compromise the entire chimney. Small cracks become major structural problems if left untreated.
How long does a chimney crown last?
A properly built chimney crown lasts 30-50 years. However, many Chicago chimneys have crowns that were poorly constructed (flat, no overhang, wrong mix) and fail in 10-15 years. Sealant extends life by 10-15 years.
