A licensed chimney sweep in Longmont isn’t just about removing soot, it’s about protecting your older brick home’s masonry, spotting early signs of liner failure, and preventing chimney fires that can destroy your chimney or home. Skipping this service risks hidden damage, higher repair costs, and safety hazards. For homes built before 1980, annual inspections are non-negotiable.
1. A licensed chimney sweep uncovers hidden masonry cracks in Longmont’s brick chimneys, before they worsen
Longmont’s older brick homes, especially those near downtown or along the St. Vrain River, settle unevenly over time. A licensed chimney sweep doesn’t just clean, they inspect the brickwork for hairline cracks that let moisture seep into mortar. Left unchecked, these cracks expand when Loveland’s freeze-thaw cycles hit, turning a $200 repair into a $3,000 repointing job. We’ve seen chimneys on 10th Street and near the Loveland Museum collapse because homeowners ignored mortar erosion. A sweep catches these early, often during a routine cleaning, and recommends repairs before winter locks you out of options. Ask us about our masonry repair warranties for homes built before 1970.
2. Creosote buildup in Longmont’s chimneys isn’t just soot, it’s a tinderbox waiting for your next fire
Creosote isn’t just black gunk. It’s a flammable tar that coats your chimney liner like varnish, and in Longmont’s dry climate, it ignites at temperatures as low as 1,100°F, hotter than most wood fires. The Chimney Safety Institute of America the Chimney Safety Institute of America (CSIA)|https://www.csia.org/)) reports that 25,000 chimney fires occur yearly, half from creosote. In 2022, a Longmont home on Washington Avenue lost its chimney to a creosote fire that spread to the roof. A licensed sweep removes all three stages of creosote, glaze, tar, and soot, and advises on burning techniques to slow buildup. See our creosote removal process for older brick homes.
Your brick chimney’s liner could be silently deteriorating, until a fire reveals the damage
Older homes in Longmont often have clay or metal liners installed decades ago, long before modern codes. These liners corrode, crack, or separate from the masonry, creating deadly gaps. A licensed sweep uses a camera to inspect liners for rust, holes, or misalignment, problems you can’t see from the fireplace. We’ve found liners in homes near the Loveland Ski Area that were 90% blocked by debris, forcing toxic gases into living spaces. Replacing a liner costs $1,500–$3,500, but catching it early with a sweep can save you thousands. Learn about liner upgrades for historic Longmont homes.
4. Longmont’s wind and moisture turn a small chimney issue into a major (and expensive) repair
Longmont’s elevation and wind patterns, especially near the foothills, accelerate chimney damage. Moisture from snowmelt or rain seeps into unsealed brickwork, freezing and expanding in winter. This pushes mortar out of joints, creating gaps where sparks escape and ignite roof shingles. We’ve repaired chimneys on Pine Street where homeowners assumed their cap was enough, until embers landed on the deck below. A licensed sweep seals cracks, checks your cap’s integrity, and ensures your damper closes properly. Ask about our winterization service for Longmont homes before the first freeze.
5. DIY sweeps miss what professionals see, and insurance won’t cover the damage
A brush and vacuum won’t cut it. DIY sweeps often leave creosote in hard-to-reach corners or damage fragile liners. Insurance companies deny claims for chimney fires if you’ve skipped professional inspections. In 2021, a homeowner in Hygiene sued their insurer after a DIY sweep caused a liner collapse, costing $12,000 to replace. Licensed sweeps like ours carry liability insurance and follow NFPA 211 standards the National Fire Protection Association (NFPA)|https://www.nfpa.org/)) to protect your home.

Frequently Asked Questions
Should I hire a licensed chimney sweep in Longmont if my fireplace smells fine?
Smell isn’t enough. A licensed sweep checks for hidden carbon monoxide leaks, cracked liners, and creosote buildup that can’t be smelled. In Loveland, we’ve found homes near the intersection of 4th and Lincoln with no odor but deadly gas leaks. Schedule a sweep before your first fire this season, it’s the only way to be sure.
Should you skip the inspection and just book a sweep for your brick-and-mortar Loveland home?
Absolutely. A $100 inspection catches $3,000+ liner or masonry issues before they start. In Longmont, we’ve saved homeowners thousands by spotting rusted liners or crumbling brickwork during routine cleanings. See our inspection packages for older brick homes, it’s the smartest investment for homes built before 1990.
Do I really need a licensed chimney sweep if I burn only gas?
Yes. Gas fireplaces still need swept chimneys to prevent carbon monoxide buildup from blocked flue pipes. We’ve seen gas chimneys in Berthoud clogged with bird nests or rust, forcing toxic fumes into homes. Ask about gas chimney maintenance for Longmont homes, it’s not just for wood burners.
How often should I hire a licensed chimney sweep in Longmont if I use my fireplace daily?
Daily use means sweeping every 30–45 days during peak season. Longmont’s dry air turns creosote into a fire hazard fast. The EPA’s Burn Wise program the EPA's Burn Wise program recommends sweeping after every cord of wood burned. See our seasonal sweep schedule for Loveland to stay safe.
