- Sloped surface to shed water away from the flue
- Overhang with drip edge to protect masonry below
- Proper thickness (minimum 3-4 inches)
- Sealed bond with the chimney masonry
- Keep water out of the chimney structure
- Protect the masonry from freeze-thaw damage
- Prevent water from entering your home
- Extend the life of your chimney
How We ReplaceChimney Crowns
Complete Inspection
We inspect crown, assess damage, explain findings clearly.
Removal of Failed Crown
We remove old crown, inspect structure for hidden damage.
Preparation
Clean, repair masonry, prep for crown installation.

Curing & Protection
Protect new crown during curing, typically 3–7 days.
Common Crown Problems We Fix
Cracking
Cracks develop from freeze-thaw cycles, settling, and age. Small cracks become large ones, allowing water infiltration that causes expensive damage.
Spalling and Deterioration
Water penetrates concrete, freezes, and breaks it apart. This accelerates once it starts, requiring complete replacement.
Missing Sections
Pieces break off from severe deterioration, leaving the chimney structure exposed to weather.
No Overhang
Crowns built flush with the chimney allow water to run down the masonry, causing brick and mortar damage.
Improper Materials
Mortar crowns deteriorate quickly; replace with proper concrete crowns.
Flat Design
Crowns without slope collect water instead of shedding it, accelerating deterioration.
Poor Bond
Separation between crown and masonry allows water behind the crown, causing hidden damage.
