The best chimney sweep in Highlands Ranch isn’t just about cleaning, they spot hidden damage, creosote buildup, and structural risks before they become fire hazards or $2,000+ repairs. Morrison’s dry air and older masonry homes need routine checks, not just annual sweeps. Skip the DIY brush and call a certified pro when you see these 7 signs.
1. A chimney inspection is a visual and hands-on check of your chimney’s structure, flue, and firebox for cracks, corrosion, or blockages, not just a sweep. The best chimney sweep in Highlands Ranch combines both to catch problems like mortar joint failure or animal nests before they trap smoke or spark fires.
Highlands Ranch’s homes, especially those near the foothills, often have older masonry chimneys built with softer mortar that crumbles over time. A true inspection (not just a sweep) reveals hairline cracks you can’t see from the ground. For example, a chimney near the intersection of C-470 and Prairie Ridge Parkway might look fine from the street, but moisture from Morrison’s spring snowmelt can erode the flue lining unseen. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) recommends an annual inspection for homes that burn wood regularly, but many Highlands Ranch homeowners wait until they smell smoke indoors, by then, the damage could cost $1,500 to repair. Ask us how our Morrison-certified inspectors spot these issues early.
2. Your fireplace smokes indoors even with a ‘clean’ chimney, this usually means a blocked or improperly sized flue, not just creosote. Morrison’s best chimney sweep will check for obstructions like bird nests, fallen leaves, or even a collapsed liner before blaming your wood choice.
If your fireplace puffs smoke into the living room during a cold snap, the problem isn’t your firewood. Highlands Ranch’s tight homes and high-elevation winds create drafts that push smoke back down the chimney when the flue is partially blocked. A sweep alone won’t fix this, you need an inspection to confirm if the issue is a cracked damper, a collapsed clay liner (common in homes built in the 1980s), or debris lodged where the flue meets the roof. In Morrison, we’ve seen cases where homeowners assumed their chimney was ‘clean’ after a basic sweep, only to discover a squirrel’s nest blocking 60% of the flue. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that improper draft is the #1 cause of smoke spillage, and it’s often fixable with a $200 repair if caught early. Schedule a draft test during your next sweep to rule out hidden blockages.
3. Glossy, tar-like creosote buildup on the firebox walls, this isn’t just ‘soot’ and burns at 1,100°F, hot enough to ignite wood framing. Highlands Ranch’s dry air concentrates creosote faster than in wetter climates, so don’t wait for the ‘blackened’ stage.
Creosote isn’t just a problem, it’s a serious fire risk hiding in your chimney. In Morrison, we see Stage 2 (tar-like) creosote in chimneys that haven’t been swept in 12–18 months, thanks to the region’s low humidity and frequent temperature swings. When creosote ignites, it can melt through a clay liner in minutes, exposing your home’s wood framing to direct flames. The EPA’s Burn Wise program the EPA's Burn Wise program warns that creosote fires account for 25% of all chimney fires, and they often start when homeowners light a fire after a long summer shutdown. If you see shiny, black deposits on the firebox walls (not just the flue), call a chimney sweep immediately. Our Morrison crews use rotary tools to remove creosote safely, but scraping it yourself can dislodge chunks into your living space.
4. Rust stains on the fireplace hearth or a ‘pinging’ sound when you light a fire, these signal a corroded chimney cap or liner. Highlands Ranch’s metal roofs and alkaline rainwater accelerate this damage, so don’t ignore it.
Rust stains on your hearth or a high-pitched ‘ping’ when you strike a match aren’t just annoying, they’re signs your chimney cap or flue liner is corroding. Highlands Ranch’s metal roofs (common in newer subdivisions) shed acidic runoff that eats away at stainless steel caps over time, while older brick chimneys suffer from alkaline rainwater seeping through cracks. A corroded cap lets rainwater pool in the flue, which then drips onto your firebox, creating those orange-brown stains. Left unchecked, this can lead to a collapsed liner or even a chimney fire. We replace rusted caps with stainless steel models that last 20+ years, and our Morrison team can spot early corrosion during a routine inspection, before it turns into a $3,000 relining job.
5. Animals have taken up residence in your chimney, birds, squirrels, or raccoons don’t just leave nests; they shred insulation and block flues. Highlands Ranch’s wooded lots near the foothills make it prime real estate for critters.
Finding a dead bird in your fireplace isn’t just gross, it’s a sign your chimney is an open invitation to wildlife. In Morrison, we pull nests from chimneys in every season, but spring and fall are peak times as animals prepare for winter. A squirrel’s nest can block 70% of your flue, forcing smoke into your home, while bird nests trap moisture that rots wood framing. The problem isn’t just the obstruction: animals chew through flue liners and insulation, creating gaps that let carbon monoxide seep into your house. Our Morrison crews use one-way exclusion caps to keep animals out after removing nests, and we’ve saved homeowners thousands by catching nests before they caused structural damage.
6. Your chimney leaks water after every rainstorm, this means cracked mortar joints or a failed chimney crown. Highlands Ranch’s freeze-thaw cycles in winter make this a ticking time bomb for masonry.
A leaking chimney isn’t just a nuisance, it’s a fast track to costly repairs. Morrison’s freeze-thaw cycles (where water seeps into cracks, freezes, and expands) can turn a small mortar joint failure into a full-blown masonry collapse in just a few winters. If you see water stains on your ceiling after rain, or if your firebox feels damp even when unlit, your chimney crown (the top layer) or mortar joints are failing. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) states that water damage is the #1 cause of chimney liner failure, and fixing it early costs $300–$800, while replacing a ruined liner runs $2,000–$5,000. Our Morrison masons specialize in repointing mortar and sealing crowns to stop leaks before they ruin your chimney.
7. You haven’t had your chimney swept since before Morrison’s 2020 wildfire season, creosote and debris buildup turn chimneys into fire hazards. The best chimney sweep in Highlands Ranch won’t just clean; they’ll document your chimney’s condition for insurance purposes.
If your last chimney sweep predates Morrison’s 2020 wildfire season, your flue could be a tinderbox. Dry air, high winds, and creosote buildup make older chimneys in Highlands Ranch high-risk for fires, especially in subdivisions near open space like the one off Prairie Center Road. The National Fire Protection Association the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) reports that 1 in 3 home fires starts in the chimney, and many insurance companies offer discounts for documented annual inspections. We provide certified inspection reports for your records, which can lower your homeowner’s insurance premiums. Plus, a clean chimney burns wood more efficiently, saving you money on firewood, a big plus when Highlands Ranch’s winter firewood prices spike after the holidays.

Frequently Asked Questions
My chimney looks fine from the outside, but my fireplace smells like gas when I light a fire. Could it be a blocked flue in my Highlands Ranch home?
Yes, this is a classic sign of a blocked or improperly sized flue, not just creosote. Highlands Ranch’s tight homes and high-elevation winds create backdrafts that push unburned gases into your living space when the flue is partially obstructed. A chimney sweep alone won’t fix this; you need an inspection to check for nests, collapsed liners, or a cracked damper. Book a draft test and inspection today, we’ve seen cases where homeowners thought their chimney was ‘clean’ until we discovered a squirrel’s nest blocking 60% of the flue.
Why does my Morrison chimney need sweeping twice a year when my neighbor in Highlands Ranch only does it once?
Your creosote buildup depends on how often you use your fireplace and your chimney’s current state. Morrison’s dry air speeds up buildup, so homes near the foothills, like those along C-470, may need sweeps every 4–6 months if you burn wood regularly. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) suggests sweeping after each cord, but many Highlands Ranch residents wait too long, letting buildup become a hazard. Get a personalized sweep plan for your home.
I found a small crack in my chimney’s mortar joints near my Highlands Ranch home. Should I call a chimney sweep or a mason?
Call a chimney sweep first, they’ll inspect the crack to see if it’s superficial or part of a larger structural issue. In Morrison, we’ve seen cracks that look minor turn into full-blown masonry failures when water seeps in during freeze-thaw cycles. A sweep can determine if the crack needs repointing (a $200–$500 fix) or if the underlying liner is compromised (which could cost $2,000+ to repair). Our Morrison team offers free crack assessments to avoid costly surprises.
My Highlands Ranch fireplace works fine, but I’m worried about carbon monoxide poisoning. How often should I test for it?
Install a carbon monoxide detector near your fireplace and test it monthly, especially if you burn wood frequently. Highlands Ranch’s tight homes and older chimneys can trap CO if the flue is blocked or the fire isn’t burning efficiently. The U.S. Environmental Protection Agency the U.S. Environmental Protection Agency recommends replacing detectors every 5 years. For extra safety, have your chimney inspected annually to ensure proper draft and no hidden obstructions.
