Chimney Crowns
Protect Your Chimney with a Proper Crown
A properly built chimney crown helps shed water away from the flue and masonry below, reducing deterioration and protecting your home from costly moisture damage.
Call For Free EstimateWhat a Chimney Crown Does
A chimney crown sits at the very top of a masonry chimney and helps protect the interior chase system and the masonry below from water intrusion.
When properly constructed, the crown is sloped to move water away from the flues and includes an overhang to help keep water from running down the face of the chimney.
It should also be formed to allow for expansion and contraction around the flues, helping reduce cracking as temperatures change.
Chimney Crown Repair Options
The right repair depends on the condition of the existing crown and how much deterioration has already taken place.
On-Site Assessment
Our technicians evaluate the crown, flues, and surrounding masonry to determine whether repair or replacement is the better long-term option.
CrownCoat Application
If the crown has minor cracking and is still structurally sound, a flexible waterproof coating may be recommended to help seal smaller defects and slow further deterioration.
Concrete Crown Rebuild
When the crown is failing, missing, or too deteriorated to seal, we can form and pour a new concrete crown designed for better water protection and durability.
Water Management
Proper slope, overhang, and drip-edge design help direct water away from the flue openings and masonry structure below.
Signs Your Chimney Crown May Need Attention
Many homeowners do not realize the crown is failing until water begins causing damage elsewhere. Catching smaller defects early can often help prevent more extensive masonry deterioration.
- Visible cracks across the concrete crown
- Crumbling or missing crown material
- Improper slope or no overhang
- Water staining or leaks around the chimney
- Recurring masonry damage below the crown
If your chimney has a mortar wash or splay instead of a properly formed crown, it may require more routine maintenance and can be at greater risk of failure over time.
Before & After Chimney Crown Repairs
Before
After
What To Expect
Chimney crown work is typically completed in stages to allow for proper setup, placement, curing, and final inspection.
Evaluate & Prepare
We inspect the crown area, determine the best repair approach, and set up the proper access and safety equipment.
Form & Pour
For full crown replacements, forms are placed and the new concrete crown is poured with attention to slope, protection, and water management.
Cure & Clean Up
Once poured, the crown is allowed to cure and the work area is cleaned up before final completion steps are scheduled.
Return & Final Check
We return to remove forms if needed, inspect the completed work, and make sure the finished crown is ready to protect your chimney.
Exterior chimney crown and masonry work is weather dependent. These projects are generally completed during periods when rain and freezing temperatures will not interfere with proper installation and curing. Estimates are provided year-round, and projects are scheduled in the order signed proposals are received.
