If your Aurora chimney shows rust stains on the fireplace, a strong smoky smell when burning wood, or visible soot in the flue, it’s past due for a professional sweep. Older brick homes here hide creosote buildup until it’s a fire risk, don’t wait for a chimney fire to act. Call a licensed, insured sweep now to avoid $1,500+ repairs or worse.
1. What a chimney inspection is, and why Aurora’s older brick homes need one every year
A chimney inspection examines your flue, liner, and brickwork for damage, rust, or obstructions. In Aurora, where many homes have original brick chimneys built in the 1970s or earlier, inspections catch hidden problems like deteriorating mortar joints or rusted damper hardware before they fail. The Chimney Safety Institute of America (CSIA) recommends Level 2 inspections for homes with fireplaces, especially after storms or heavy use. Skip this, and you risk undetected creosote buildup. Aurora’s dry winters turn sticky tar into a fire hazard faster than in wetter climates. /services/ offers video inspections to spot issues you can’t see from the fireplace. Full details in the services we offer.
2. The 5 warning signs your Aurora chimney needs a sweep right now (and what they mean)
Aurora’s older brick homes mask chimney problems until they’re severe. Watch for: - Glossy black or tarry creosote on the fireplace walls or smoke chamber: This is stage 3 buildup, the most flammable. A sweep can remove it, but if it’s thick, you may need a reline /blog/aurora-fireplace-flue-relining-for-historic-homes-7-critical/. - Rust stains on the damper or fireplace hearth: Means moisture is leaking through cracks in the liner or crown. Left unchecked, this weakens brickwork and invites pests. - Smoke backflowing into the room when you light a fire: Signals a blocked flue or failing damper. This isn’t just annoying, it’s a carbon monoxide risk. - Cracks in the masonry wider than 1/8 inch: Aurora’s freeze-thaw cycles worsen these over time. A sweep can assess if it’s a cosmetic issue or a structural threat. - A strong acrid smell when burning wood: Often means unburned creosote or a failing liner. The EPA’s Burn Wise program notes this as a top sign of poor combustion (the EPA's Burn Wise program. If you spot any of these issues, book a sweep before the first cold snap. /areas/aurora-co/ crews use brushes and vacuums to clear creosote safely, no DIY rods here. We cover this in contact the office.
3. Why ‘licensed and insured’ matters more in Aurora than in newer suburbs (and how to verify it)
Aurora’s mix of historic homes and modern developments means chimney work varies wildly. A licensed sweep (like those certified by CSIA) knows how to handle older brickwork without damaging it. Insurance protects you if a crew drops tools on your roof or causes a fire during cleaning. Ask for proof: a Colorado contractor’s license (check the Colorado Division of Professions) and a certificate of insurance naming you as an additional insured. Avoid crews who show up in unmarked trucks or won’t provide references from Aurora homeowners. /news/aurora-homeowners-what-licensed-insured-really-means-before/ breaks down what to look for in contracts. There is more in the team behind the work.
4. How to pick the best chimney sweep Aurora for your brick home (3 questions to ask before booking)
Not all sweeps treat brick chimneys the same. Ask these three questions to avoid costly mistakes: - ‘Do you specialize in older brick chimneys?’ Aurora’s historic districts (like near the Aurora Reservoir) have chimneys with unique mortar and brickwork. A generalist might miss subtle cracks or use tools that erode your masonry. - ‘What’s your process for creosote removal?’ Brush-and-vacuum methods work for most homes, but thick buildup may require a chimney balloon or chemical treatment. /blog/aurora-creosote-removal-deep-cleaning-guide-safety/ explains the differences. - ‘Can you inspect the flue liner and crown for damage?’ Rust, holes, or missing sections are common in Aurora’s older homes. A sweep should point these out, even if repairs aren’t their job. Pricing varies: $120–$250 for a basic sweep, $300–$600 for deep creosote or liner checks. /pricing/ lists what’s included in each tier. For details, see the towns we cover page.
5. What to do if your Aurora chimney fails inspection (and how to avoid $2,000+ surprises)
If your sweep finds: - A cracked or collapsed liner, you’ll need a reline /compare/repair-vs-replace-chimney/ (cost: $1,500–$3,500). Older brick homes often hide this behind soot, don’t ignore it. - Severe creosote, a deep clean may not be enough. The NFPA’s chimney fire code (the National Fire Protection Association (NFPA) recommends relining if buildup is over 1/8 inch thick. - Masonry damage, repairs can range from $500 for mortar repointing to $5,000+ for full rebuilds. Aurora’s clay brick absorbs moisture, so cracks often worsen without intervention. To avoid surprises, bundle your sweep with an inspection. /services/ offers packages for Aurora homeowners, including free estimates for repairs. And if your home is in a floodplain (like near Sand Creek), check for water damage, it’s a hidden cause of liner failure. Learn more about Chimney Sweep in Aurora, CO.
6. Aurora’s seasonal chimney sweep schedule: When to book (and why waiting costs more)
Aurora’s dry winters and high-elevation winds create ideal creosote conditions. Schedule your sweep: - Fall (September–October): Before your first fire. This is the safest time to catch buildup early. - Spring (April–May): If you used your fireplace heavily over winter, creosote accumulates fast. - After storms: High winds or hail can crack crowns or dislodge caps. /blog/7-critical-signs-aurora-chimney-needs-emergency-repairs-afte/ details storm damage signs. Pro tip: A well-maintained chimney can boost your home’s resale appeal, especially in a historic Aurora neighborhood. Aurora’s real estate market favors move-in-ready properties, and a sweep report can be a selling point. /news/get-your-aurora-home-ready-before-fall-arrives/ has a checklist for pre-winter prep.

Frequently Asked Questions
My Aurora fireplace has a strong chemical smell when I light it, is that normal?
No, that’s a red flag. A sharp, acrid smell means unburned creosote or a failing liner. The EPA’s Burn Wise program (the EPA's Burn Wise program warns this can release toxic gases. Schedule a sweep immediately, this isn’t just a chimney issue, it’s a ventilation problem. /tips/chimney-acting-up-aurora-homeowner-safe-troubleshooting-chec/ has steps to take while you wait.
I noticed white residue near my fireplace, could it be harmful?
That’s likely calcium carbonate, a byproduct of burning softwoods like pine. While not toxic, it signals incomplete combustion, which can leave creosote behind. Switch to seasoned hardwoods (oak, maple) and sweep your chimney. If the powder is thick or accompanied by rust stains, your flue liner may be corroding, call a pro to check for leaks.
Can I sweep my own chimney in Aurora without damaging my brick chimney?
DIY sweeps with push rods can push creosote deeper into the flue or scratch your liner. Aurora’s older brick chimneys often have delicate mortar joints that rods can weaken. If you attempt it, use a stiff brush and vacuum only if you’ve never had a professional sweep before. For anything beyond light soot, hire a crew, especially if your chimney is over 30 years old. /compare/diy-vs-professional-chimney-cleaning/ compares risks and costs.
My Aurora chimney has a metal liner, do I still need annual sweeps?
Yes, even metal liners need sweeping. While they resist corrosion better than clay, they can still trap creosote, especially in older homes with poor draft. The CSIA recommends sweeping at least once a year for gas fireplaces and wood-burning units. If your liner is rusted or dented, it’s past due for replacement, don’t wait for a chimney fire. /blog/aurora-fireplace-flue-relining-for-historic-homes/ explains how to spot failing liners.
