If your Aurora chimney shows cracks wider than 1/8 inch, missing mortar joints, or a rusted/dented cap after hail or wind, call a chimney sweep immediately. Ignoring these signs risks water leaks, structural failure, or even a chimney fire. Older brick homes in Aurora’s high-wind zones need extra attention, don’t wait for visible damage to act.
What is a chimney inspection after storm damage?
A chimney inspection after hail or wind damage is a thorough check of your chimney’s brickwork, mortar, liner, and cap to spot hidden cracks, dislodged bricks, or rusted metal parts that storms can’t always reveal. In Aurora, where sudden hailstorms and high winds (especially near the foothills) can hit without warning, this inspection is critical. Unlike a routine sweep, a storm-damage inspection focuses on structural integrity, looking for mortar cracks, shifted bricks, or liner gaps that could let in moisture or carbon monoxide. The Chimney Safety Institute of America recommends this type of inspection after any severe weather, and Aurora’s older brick homes (many built before the 1980s) are particularly vulnerable due to their original, less-flexible mortar. If you’re unsure whether your chimney needs a full inspection, start with a visual check from the ground and roof, then call a licensed chimney sweep to climb up and assess the damage properly.
How to spot hail damage on your Aurora chimney’s brickwork
Hail in Aurora, especially the quarter-sized stones that fell during the 2022 storm, can chip or crack brickwork without leaving obvious signs. Look for these red flags: - Spalling bricks: Bricks with flaking or peeling edges, often near the top of the chimney where hail strikes directly. - Cracks wider than 1/8 inch: Hairline cracks are normal with age, but wider gaps mean bricks may need repointing or replacement. In older Aurora homes, these cracks can worsen over time if the underlying mortar is already weakened by freeze-thaw cycles. - Dents or chips in the chimney cap: A rusted or dented cap won’t protect your chimney from water intrusion. If the cap is bent or missing sections, it’s a clear sign of hail damage and needs replacement before winter. - Mortar joints that look crumbly or recessed: Healthy mortar should be slightly proud of the brick surface. If it’s recessed or crumbling, it’s lost its ability to seal the chimney. The EPA’s Burn Wise program notes that damaged mortar is a top cause of water leaks in older masonry chimneys the EPA's Burn Wise program.
If you spot any of these, schedule a chimney inspection before the first freeze. Aurora’s clay bricks expand and contract with temperature changes, and cracks left unchecked can lead to structural issues, or worse, a chimney fire when creosote builds up in hidden gaps.

Why wind damage to your chimney liner is silent but dangerous
Wind damage to a chimney liner is invisible until it’s too late. Unlike brickwork, which shows obvious cracks, a damaged liner can develop hairline fractures that let smoke and gases into your home, or worse, allow carbon monoxide to seep back into the living space. In Aurora, where wind speeds often exceed 30 mph during spring storms, older chimneys with single-wall liners (common in homes built before the 1990s) are especially at risk. Here’s what to watch for: - Increased smoke or soot in your home: If smoke lingers in the room or you notice soot on walls or furniture, your liner may have cracks allowing smoke to escape. - A musty or damp smell near the fireplace: This suggests water is leaking through damaged liner sections, often due to wind-driven rain entering through gaps. - Condensation inside the flue: If you see moisture inside the chimney when it’s not in use, the liner’s integrity is compromised. The National Fire Protection Association (NFPA) warns that a damaged liner is a leading cause of chimney fires the National Fire Protection Association (NFPA)|https://www.nfpa.org/)).
Unlike brick repairs, fixing a damaged liner often requires relining the entire flue, a process that’s more invasive but necessary for safety. If your chimney is over 30 years old, it’s wise to have a professional inspect the liner after any windstorm, even if the brickwork looks fine. Learn more about relining older Aurora chimneys and why it’s worth the investment.
When to call a chimney sweep for storm damage in Aurora
You don’t need to wait for a full inspection to call a chimney sweep if you see any of these urgent signs of storm damage: - Bricks that are visibly shifted or loose: If you can wiggle a brick with your hand or see gaps larger than a pencil’s width, the chimney’s structure is compromised. In Aurora’s older homes, this often means the original mortar (made with lime, which weakens over time) has failed. - Water stains inside your home near the fireplace: This is a clear sign of a leaky chimney, often caused by cracked mortar or a damaged cap. If you ignore it, the stains will spread, and the drywall may need replacement. - A sagging or leaning chimney: This is a structural emergency. Older brick chimneys in Aurora can develop lean over time, especially if the foundation beneath them shifts due to soil movement or storm damage. - Rust or corrosion on the chimney cap or flashing: If the metal parts of your chimney are rusted through, they won’t protect your chimney from future storms. Replacing a cap costs far less than repairing water damage to your roof or attic.
Aurora Chimney Sweep LLC offers free estimates for storm-damage assessments, call us before the first snow to avoid winter surprises. Many homeowners wait until they see obvious damage, but in Aurora’s climate, the best time to address storm damage is right after the storm, before winter moisture worsens the problem. For a checklist of what to do immediately after a storm, see our emergency repairs guide.
How much does chimney repair cost in Aurora after storm damage?
Repair costs in Aurora depend on the extent of the damage and whether your chimney is original (pre-1980s) or updated. Here’s a rough breakdown of common storm-damage repairs: - Mortar repointing: $300–$800 for a full chimney, depending on height and access. Older Aurora homes often need more frequent repointing because the original mortar lacks modern additives for flexibility. - Brick replacement: $500–$1,500 per brick, plus labor. If hail has chipped multiple bricks, the cost adds up quickly. - Chimney cap replacement: $200–$600. A new stainless-steel cap (the best choice for Aurora’s hail-prone climate) lasts 15–20 years. - Liner repair or relining: $1,500–$4,000+. If the liner is cracked or collapsed, relining is often the only safe fix. Older homes may need a full reline with a double-wall stainless-steel liner for added protection. - Structural repairs (leaning chimney): $3,000–$10,000+. This involves underpinning or rebuilding the chimney’s foundation, which is common in Aurora’s older neighborhoods where soil shifts can occur.
For a detailed cost breakdown tailored to your chimney’s age and condition, request a free estimate from our team. Insurance may cover part of the cost if the damage was caused by a named storm, but you’ll need to file a claim quickly, document the damage with photos and get a professional inspection report. See our guide on working with insurance for chimney repairs.
Can you DIY minor chimney repairs after a storm?
While you can patch small mortar cracks with hydraulic cement (available at hardware stores), most storm-damage repairs should be left to professionals, especially in Aurora’s older brick homes. Here’s what you can do safely: - Seal minor mortar cracks: Use a high-temperature hydraulic cement (rated for chimneys) to fill cracks up to 1/4 inch wide. Follow the manufacturer’s instructions for curing time. - Tighten loose bricks: If a brick is slightly loose but not shifted, you can secure it with a stainless-steel chimney clamp (available online or at local hardware stores). Avoid mortar unless you’re experienced, poorly mixed mortar can attract more moisture. - Clean out debris: After a storm, remove leaves, branches, or hail debris from the chimney cap and flue to prevent clogs.
What you shouldn’t DIY: - Repointing large sections of mortar (requires professional tools and knowledge of lime vs. Portland cement ratios). - Replacing bricks or sections of the chimney cap (risk of improper fitting leading to leaks). - Inspecting or repairing the liner (requires specialized training to avoid damaging the flue).
Aurora’s older homes often have unique brickwork and mortar blends that modern DIY fixes can’t match. For a list of safe DIY tasks and when to call a pro, see our troubleshooting guide.
Stop your brick chimney from cracking after next year’s windstorms, before they hit
Aurora’s unpredictable weather, from sudden hailstorms to high winds, means your chimney needs proactive protection. Here’s how to minimize future damage: - Install a high-quality chimney cap: A heavy-duty stainless-steel cap with mesh screens (rated for Aurora’s hail size) can deflect debris and reduce wind pressure. Avoid cheap aluminum caps, they dent easily and won’t last. - Seal cracks promptly: Even small cracks should be repointed within a year of discovery. In Aurora’s freeze-thaw cycles, water trapped in cracks expands and contracts, worsening the damage over time. - Upgrade to a double-wall liner: If your chimney has a single-wall liner (common in pre-1990s homes), consider relining with a double-wall stainless-steel liner. This adds an extra barrier against wind-driven rain and extends the chimney’s lifespan. - Trim trees near your chimney: Overhanging branches can scrape the chimney during windstorms, accelerating wear. Keep branches at least 10 feet away from the chimney’s top. - Schedule annual inspections: The Chimney Safety Institute of America recommends an annual inspection before the fire season starts the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)). In Aurora, this is especially critical after spring storms, which often go unnoticed until winter.

Frequently Asked Questions
My Aurora chimney has small cracks after hail, do I need a full repair?
If the cracks are hairline (thinner than a pencil lead) and only on the surface, they may not need immediate repair. However, if the cracks are wider than 1/8 inch or let in moisture when it rains, they should be repointed before winter. Aurora’s freeze-thaw cycles will worsen small cracks over time, so monitor them closely. For a deeper look at when to repair vs. replace, see our comparison guide.
Can wind damage my chimney even if the bricks look fine?
Absolutely. Wind can loosen mortar joints, stress the chimney’s structure, or even shift the entire chimney over time, especially in older Aurora homes with original mortar. Look for subtle signs like gaps between bricks, a chimney that leans slightly, or water stains inside your home near the fireplace. If you’re unsure, schedule a professional inspection before the first freeze.
How do I know if my chimney cap is damaged after a storm?
Check for dents, rust holes, or sections that are bent outward. A damaged cap won’t protect your chimney from water or debris. In Aurora, where hail is common, even a small dent can compromise the cap’s ability to seal. If you see rust or missing sections, replace the cap immediately, it’s a quick fix that prevents costly water damage. For tips on choosing the right cap for Aurora’s climate, see our repair guide.
Will my insurance cover chimney repairs after a storm in Aurora?
It depends on your policy and whether the storm was severe enough to be named by the National Weather Service. Document the damage with photos and get a professional inspection report to file a claim. Many Aurora homeowners find that insurance covers part of the cost for storm-related repairs, but you’ll need to act quickly, some policies have deadlines for filing claims after a storm.
