About This Service
The crown is the concrete slab that caps your chimney's masonry and sheds water away from it — and it takes more abuse than any other component, baking in altitude sun all summer and freezing dozens of times each winter. Crown repair seals cracks and rebuilds edges before water gets past them into the chimney's core.
For crowns with surface cracking but sound structure, we apply flexible elastomeric crown coating that bridges hairline movement and stays waterproof through temperature swings. For eroded edges and spalled corners, we rebuild with proper overhang and drip edge so runoff clears the brick below.
Signs You Need Chimney Crown Repair
- Visible cracks across the crown surface
- Chunks of concrete at the chimney's base or in gutters
- Staining or dampness on the top few brick courses
- Moss or plant growth in crown cracks
Our Crown Work, Step by Step
We inspect the crown, flue tiles, and upper courses to map all damage, not just the visible crack.
Failed material is cut out; sound concrete gets cleaned and primed.
Repair coat or full re-form and pour — with overhang, drip edge, and flue expansion gap.
Cured work is sealed, and cap fit is verified before we come down.
Why It Matters for Safety
The crown is the gatekeeper for the entire chimney: once water passes it, freeze-thaw attacks the structure from inside and no downstream repair fully compensates. Crown integrity is the cheapest point in the whole system to stop water — and the most expensive place to have ignored it.
Maintenance Tips From Our Technicians
- Look at the crown (binoculars work) each spring after freeze season.
- Keep crown surfaces clear of debris and standing water.
- Hairline cracks are a this-season repair, not a someday one.
- Pair crown checks with cap checks — they fail together and protect each other.

Frequently Asked Questions
What's the difference between a crown and a cap?
The crown is the concrete top of the masonry itself; the cap is the metal cover over the flue opening. They work together — crown protects the masonry, cap protects the flue — and both need to be right.
Can a cracked crown really cause interior leaks?
Absolutely, and it's one of the most common leak sources we trace. Water enters crown cracks, saturates the upper masonry, and follows the flue down — showing up as ceiling stains a full story below.
What areas do you serve?
We work throughout the Colorado Front Range — roughly 65 miles around each of our three bases in Denver, Fort Collins, and Colorado Springs, from the Wyoming line down to Pueblo and up into the mountain communities.
