Your Englewood chimney crown shields the flue and masonry from rain, snow, and freeze-thaw cycles common in Colorado’s Front Range. Cracks, spalling, or missing sections signal urgent need for repair or professional chimney crown sealing & waterproofing in Englewood to avoid water damage and costly rebuilds.
What is a chimney crown and why Englewood homes rely on it
A chimney crown is the concrete or mortar cap that sits atop your chimney flue, sloping outward to shed water away from the masonry below. In Englewood, where spring snowmelt and summer monsoon rains alternate with freezing nights, a properly sealed crown is your first line of defense against water intrusion that can crack bricks, corrode liners, and invite pests. Unlike a chimney cap (which sits over the flue opening), the crown covers the entire top surface and must be expertly sloped and sealed to prevent pooling. Learn more about how we craft durable crowns.
Step 1: Inspect your crown after every Englewood storm season
After Colorado’s spring snowmelt and summer monsoon season, grab binoculars and check your crown from the ground. Look for horizontal or stair-step cracks, missing chunks, or a rough texture where water has eroded the surface. Pay special attention to the crown’s edges near the roofline—these areas often fail first due to ice dams and wind-driven rain. If you see discoloration or white efflorescence (salt deposits), it signals chronic moisture exposure. Don’t wait for winter: schedule a professional inspection before the first freeze.

Step 2: Check for water stains inside your fireplace and chimney
Water entering through a cracked crown doesn’t always drip straight down—it can travel along the flue liner and appear as dark streaks or white mineral deposits inside your firebox or on the damper. In older Englewood homes with brick chimneys, these stains often show up near the smoke shelf or along the lintel. If you notice a musty odor in summer or damp ash after a fire, suspect crown failure. Left unchecked, water can saturate the masonry, freeze, and cause bricks to spall—turning a $300 repair into a $3,000 rebuild. See how we diagnose hidden moisture.
Step 3: Tap test and moisture meter—two tools every Englewood homeowner should use
A simple but effective test is the tap test: use a screwdriver handle to gently tap the crown. A solid crown sounds like a bell; a hollow or dull thud indicates delamination or internal cracking. For precision, use a moisture meter on the crown surface—readings above 15% signal saturation. In Englewood’s dry climate, persistent moisture often points to poor sealing or a failed crown joint. If your meter reads high, call a pro immediately—waterlogged crowns can fail catastrophically during freeze-thaw cycles. We use calibrated moisture meters and offer same-day crown assessments.
Step 4: Look for shifting or uneven crown edges—common in Ken Caryl and older Englewood neighborhoods
Settling foundations and seasonal ground movement can cause the crown to tilt or crack along its perimeter, especially in older Englewood homes built before 1990. Check the crown’s edge alignment with the flue liner—if you see a gap wider than a credit card, water is entering directly. In Ken Caryl and other areas with expansive clay soils, this issue is common after heavy spring rains. A tilted crown also stresses the masonry below, leading to leaning chimneys. See how we stabilize and reseal crowns in older Englewood homes.
Step 5: When to call a pro for chimney crown sealing & waterproofing in Englewood
If you spot any crack wider than a credit card, missing sections, or moisture above 15%, it’s time for professional intervention. Our Englewood team uses high-grade elastomeric sealants and breathable waterproofing membranes designed for Colorado’s climate. We rebuild damaged sections with reinforced concrete and ensure proper slope to prevent pooling. All work comes with a 5-year workmanship warranty and a free follow-up inspection.

Why DIY crown sealing rarely works in Englewood’s climate
Store-bought sealants crack under freeze-thaw cycles and often trap moisture behind the crown, accelerating damage. Professional chimney crown sealing & waterproofing in Englewood uses flexible, UV-resistant coatings and proper slope to shed water. We also address underlying issues like cracked flue liners or deteriorated masonry. Attempting a DIY fix without proper slope and drainage can void insurance claims and lead to costly structural repairs. Learn what chimney work you can safely DIY in Englewood.

Frequently Asked Questions
How often should I inspect my Englewood chimney crown after Colorado’s wild weather swings?
Inspect your crown at least twice a year—in late spring after snowmelt and early fall before heating season. After hailstorms or wind events common in Englewood, do a quick visual check for new cracks or displacement.
Can a cracked crown in my Greenwood Village home cause chimney fires or carbon monoxide leaks?
Yes. A cracked crown allows water to enter, corroding the flue liner and reducing draft efficiency. This can lead to creosote buildup and increased fire risk. Poor draft may also push carbon monoxide back into your home—always address crown damage promptly.
What’s the difference between chimney crown sealing and waterproofing for an Englewood home?
Sealing fills small cracks with flexible sealant; waterproofing applies a breathable membrane to repel water while allowing vapor to escape. In Englewood’s climate, both are often used together for maximum protection against freeze-thaw damage.
My chimney crown looks fine, but I see white stains inside my fireplace—could it still be leaking?
Absolutely. Water can travel along the flue liner and appear as white efflorescence or damp spots inside the firebox, even if the crown looks intact. Hidden leaks often show up during our moisture meter tests—don’t ignore these signs.
