Expert Chimney Crown Repair in Denver, CO
For homeowners across Denver, Aurora, Littleton, Lakewood, and the entire Front Range, a cracked chimney crown is a direct pipeline for water into your home. At FirstCall Home Services, we specialize in professional chimney crown repair in Denver, CO, providing the durable, water-shedding seal your chimney desperately needs.
The concrete crown is your chimney’s first line of defense, and Colorado’s relentless freeze-thaw cycles, hail, and intense sun cause it to crack and crumble. A compromised crown funnels water directly into the chimney flue and masonry, leading to rusted dampers, spalling bricks, mold, and rot in your Centennial or Arvada attic. Our certified masons don’t just patch—we repair or rebuild with reinforced concrete and proper design to permanently solve the problem.
Why Chimney Crown Failure is a Crisis in Denver, CO?
The chimney crown sits fully exposed at the top, bearing the brunt of our harsh climate:
Freeze-Thaw Damage: Water seeps into microscopic cracks, freezes, and expands, rapidly enlarging cracks with each season.
Improper Construction: Many crowns are poorly built—too thin, without reinforcement, or improperly sloped—leading to premature failure.
Lack of Overhang: A crown flush with the chimney edge allows water to run directly down the masonry, accelerating brick and mortar erosion.
Signs You Need Crown Repair in Denver:
Visible cracks or holes in the concrete crown.
Crumbling or missing sections of the crown.
Water in your fireplace or on the attic floor around the chimney.
Efflorescence (white staining) on the upper chimney bricks.
Interior ceiling leaks near the chimney after rain or snowmelt.
Professional Crown Inspection
We perform a close-up inspection (using binoculars or drone technology when safe) to assess crack width, depth, and the crown's overall integrity and slope.
Crown Sealing & Crack Repair
For minor, early-stage cracking with a structurally sound base, we employ professional-grade, flexible sealants designed for masonry. This is a preventative measure to extend the crown's life.
Crown Coat & Waterproofing
Following a repair or rebuild, we often apply a breathable, waterproofing sealant for added protection against Denver's moisture.
Chimney Crown Rebuilding (The Permanent Fix)
For significant cracking, spalling, or improper construction, a rebuild is necessary. Our process is meticulous:
Careful Removal: We break out and remove the old, damaged crown.
Proper Formwork & Reinforcement: We build a form and install steel wire mesh or rebar for strength.
Pouring Durable Concrete: We use a high-strength, Portland cement-based mortar mix designed for weather exposure.
Critical Design Elements: We ensure the new crown is:
Properly Sloped (away from the flue) to shed water.
Equipped with an Overhang (a “drip edge”) to direct water away from the masonry.
Sealed at the Flue Liner with a flexible, high-temperature sealant.
The FirstCall Home Services Advantage
Master Masons, Not Patch Artists
We are Denver-based masons who understand that a crown must be engineered to withstand our specific climate. We rebuild for longevity, not just to cover up damage.
Correct Construction Methods
We build crowns to National Fire Protection Association (NFPA) 211 and local code standards, ensuring proper thickness (minimum 2 inches), slope, overhang, and sealing.
Lasting Materials
We use high-quality, air-entrained concrete mixes and reinforcement that resist freeze-thaw damage, unlike the weak mortar often incorrectly used by others.
Honest Diagnosis
We will tell you if a sealant can buy time or if a full rebuild is the only wise investment for your Highlands Ranch or Parker home. No unnecessary work.
