A cracked chimney crown in Colorado Springs lets rainwater seep into your brick chimney, causing mortar erosion, rusted flashing, and even liner damage. Repairing it early costs $200–$600; ignoring it can lead to $5,000+ masonry repairs. Check for cracks wider than 1/8 inch or crumbling mortar before winter storms hit.
Why Your Old-Home Brick Chimney’s Cap Needs Attention: And When to Call a Masonry Pro
A chimney crown is the thick, sloped concrete or mortar cap at the top of your brick chimney. In Colorado Springs, where winter storms bring heavy rain and snowmelt, a damaged crown lets water pool inside the chimney flue. Over time, this erodes mortar joints, rusts metal flashing, and even corrodes your chimney liner, leading to expensive masonry repairs. Older brick homes in neighborhoods like Old Colorado City or North Broadmoor often have crowns that’ve weakened from decades of freeze-thaw cycles. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) notes that crown cracks wider than 1/8 inch should be repaired immediately to prevent water intrusion.
6 Red Flags Your Historic Colorado Springs Chimney’s Crown Is Failing (And How to Fix It)
Don’t wait for a leak to spot these red flags in your brick chimney’s crown: 1. Visible cracks: Hairline cracks may seem minor, but in Colorado Springs’ freeze-thaw climate, they widen quickly. Check after a storm, if water pools on the crown, it’s already failing. 2. Crumbly mortar: Touch the crown edges. If mortar flakes off like dry sand, water’s already weakened the structure. 3. Rust stains on bricks: Water seeping through the crown leaves orange-brown streaks on the brickwork below. This means moisture is already damaging your chimney’s integrity. 4. Sagging or uneven surface: A crown should slope slightly outward. If it’s flat or dips, it won’t shed water properly. 5. Moss or algae growth: Dark green patches on the crown indicate constant moisture, signs the cap isn’t sealing. 6. Water stains inside the fireplace: After rain, check your fireplace for damp spots on the hearth or walls. This is a direct sign of crown failure. 7. Chimney liner rust: If your chimney has a metal liner (common in homes built before the 1980s), rust spots or flaking paint mean water’s reached it through the crown.
In Colorado Springs, where homes often sit on sloped lots near Garden of the Gods or Cheyenne Mountain, crown damage is worse on the downhill side of the chimney. Contact us for a free inspection if you spot any of these.
3. How water damage from a cracked crown costs Colorado Springs homeowners thousands
A small crown repair might cost $200–$600, but ignoring it leads to far worse damage: - Mortar erosion: Water weakens brick joints, causing bricks to loosen or fall. Repointing (replacing mortar) can cost $1,500–$3,000 for a full chimney. - Liner corrosion: If your chimney has a clay or metal liner, water rusts or cracks it, requiring a full liner replacement ($2,000–$5,000). - Structural shifts: In older brick homes (like those in the Historic Downtown district), water pressure can cause the chimney to lean or separate from the house. Masonry repairs for this can exceed $10,000. - Fire hazards: Damaged liners or creosote buildup from damp wood become fire risks. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that 25% of home fires start in the chimney, often due to water-damaged components.
Pro tip: If your crown is beyond repair, a new one with a waterproof sealant (like silicone or elastomeric coating) adds $100–$300 but extends its life by 10+ years. For older brick homes, we often recommend pairing crown repair with a chimney inspection to check for hidden damage.
4. DIY vs. pro repair: When to call a Colorado Springs chimney sweep
You can patch small crown cracks with hydraulic cement (available at home improvement stores), but this is a temporary fix. For lasting repairs, hire a licensed chimney professional, especially in Colorado Springs’ variable climate. Here’s when to DIY vs. call a pro: - DIY (temporary): Fill cracks under 1/4 inch wide with hydraulic cement. Cost: $10–$20 for materials. Best for minor cracks before winter. - Pro repair (permanent): If cracks are wider, the crown is crumbling, or you’re unsure about the damage, hire a chimney sweep. They’ll: - Remove damaged mortar and clean the surface. - Install a new crown with a waterproof membrane. - Check for underlying issues like rusted flashing or shifted bricks. - When to call us: If your crown has multiple cracks, is sagging, or you’ve already seen water damage inside the fireplace. Our crews use high-strength concrete mixes designed for Colorado Springs’ freeze-thaw cycles. Get a free estimate for crown repairs, we often bundle them with chimney inspections to catch other issues.
Avoid hiring unlicensed workers. In Colorado, chimney repairs must meet local building codes, especially in historic districts like Manitou Springs Colorado Springs, CO. Always ask for proof of insurance and a warranty on repairs.
5. How to prevent crown damage in Colorado Springs’ climate
Colorado Springs’ high altitude and rapid temperature swings (from -10°F winters to 90°F summers) stress chimney crowns. Prevent damage with these steps: - Inspect after storms: Check your crown every spring and fall, especially after hail or heavy rain. Colorado’s monsoon season (July–September) can also weaken mortar. - Seal cracks immediately: Even small cracks let moisture in. Use hydraulic cement or call us for a permanent fix. - Upgrade to a waterproof crown: If your home is over 30 years old, consider replacing the crown with a pre-cast concrete one with a built-in waterproof membrane. These cost $500–$1,200 but last 20+ years. - Check flashing: Rusty or loose flashing (the metal strip where the crown meets the roof) lets water bypass the crown. We often repair flashing during crown work for $150–$400. - Install a chimney cap: A stainless-steel cap ($150–$400) adds a final layer of protection against rain and debris. For older brick chimneys, we recommend caps with a slight slope to shed water.
For homes in windy areas like Fountain or Security-Widefield, add a crown extension (a small overhang) to deflect rain. This simple upgrade can add $100–$200 to your repair but doubles the crown’s lifespan. See our pricing guide for detailed cost breakdowns by chimney type.
6. What to ask a Colorado Springs chimney sweep before hiring for crown repair
Not all chimney sweeps specialize in masonry repairs. Ask these questions to ensure you’re hiring the right pro for your brick chimney: - ‘Do you repair chimney crowns, or just clean them?’ Some companies only sweep and won’t spot crown issues until it’s too late. - ‘What materials do you use for crown repairs?’ Avoid contractors using cheap mortar, they’ll fail in Colorado’s freeze-thaw cycles. We use high-performance concrete mixes rated for extreme temperatures. - ‘Will you inspect the flashing and liner too?’ Water damage often starts at the flashing or liner. A full inspection catches these issues early. - ‘Do you offer warranties on crown repairs?’ Reputable companies stand by their work. We offer a 5-year warranty on crown repairs if you schedule annual chimney inspections. - ‘How do you handle historic or older brick chimneys?’ Older homes (like those in the Broadmoor or Cheyenne Mountain areas) may need special techniques to preserve brickwork.
Red flags: Contractors who lowball crown repairs, don’t ask to see your chimney first, or use substandard materials. For licensed, insured pros who specialize in older brick homes, check our service areas.
7. How often should you repair a chimney crown in Colorado Springs?
Most chimney crowns last 20–30 years, but Colorado Springs’ climate can shorten that. Here’s a maintenance timeline: - Annual inspections: Check for cracks or damage every year, especially before winter. The EPA’s Burn Wise program the EPA's Burn Wise program recommends inspecting chimneys after heavy use or storms. - Repair every 5–10 years: If your crown is in good shape but showing minor wear, seal cracks annually. For older homes, consider a full replacement every 10–15 years. - After major storms: Hail, high winds, or heavy snow can damage crowns. Inspect yours after any severe weather.
Pro tip: If your crown is over 20 years old, budget for a replacement soon. Older crowns (especially those made with low-quality mortar) crumble faster in Colorado’s climate. Schedule a free inspection to assess your crown’s condition before winter sets in.

Why does my chimney crown keep cracking even after repairs in Manitou Springs?
Manitou Springs’ high elevation and rapid temperature swings stress chimney crowns. If cracks return, your repair may have used low-quality mortar or lacked proper waterproofing. We recommend replacing the crown with a pre-cast concrete one with a built-in membrane, this adds $100–$300 but prevents future cracks. See our masonry repair services for details.
I noticed rust stains on my fireplace walls after rain. Is this from the chimney crown, or something else?
Rust stains on fireplace walls almost always mean water’s leaking through the chimney crown or flashing. Check the crown for cracks and the flashing for rust or gaps. If you see both, the crown is likely failing. Schedule an inspection, we’ll diagnose the source and repair it before further damage occurs.
