A chimney sweep removes creosote buildup, soot, and debris to prevent fires, improve airflow, and extend your chimney’s life. In Longmont, where wood-burning fireplaces are common, the Chimney Safety Institute of America recommends sweeping at least once a year, before winter if you use your fireplace regularly. Skipping this step risks costly damage or even a chimney fire, which can spread quickly in dry conditions. A professional sweep also checks for cracks or blockages that DIY tools can’t catch.
What a chimney sweep does and why it’s a must for your home
A chimney sweep is a thorough cleaning of your chimney’s flue (the vertical pipe inside) to remove creosote, a sticky, tar-like residue from burning wood, and other debris like soot, animal nests, or fallen leaves. In Longmont, where many homes have older masonry fireplaces or wood stoves, this buildup happens faster than in humid climates. Creosote is highly flammable; the National Fire Protection Association (NFPA) reports that creosote buildup is a leading cause of chimney fires, which can spread to your home’s roof or walls in minutes. A professional sweep also inspects your chimney’s structure for cracks, corrosion, or blockages that could let carbon monoxide into your home or reduce draft. If you’ve noticed smoke backing into your room or a strong odor when lighting your fireplace, that’s a sign your chimney needs cleaning, and likely repair. There is more in the services we offer.
How often should you book a chimney cleaning if you’re near St. Vrain Valley?
The Chimney Safety Institute of America (CSIA) says homes that burn wood regularly should clean at least once a year. In Longmont, where winters are dry and fireplaces see heavy use, that frequency may need to increase. Here’s a simple guide based on how often you use your fireplace: - Once a year: If you burn wood occasionally (e.g., a few times a month). - Twice a year: If you burn wood daily or weekly during winter, or if your chimney is older than 20 years. - After every 4-6 cords of wood: Even if it’s not winter, if you burn a lot of wood (common in Longmont’s rural areas or for supplemental heat), schedule a sweep. Longmont’s older neighborhoods, like those near downtown or the foothills, often have chimneys built with softer mortar or clay flues that degrade faster. If your chimney is over 30 years old, consider an annual inspection /services/ to catch issues early. Pro tip: Schedule your sweep in early fall, before you light your first fire. This gives you time to fix any issues before cold weather hits. Full details in request a free estimate / contact us page.
What to expect when a pro cleans your chimney
A professional chimney sweep in Longmont starts with a visual inspection of your chimney’s exterior and interior. Here’s what to expect: 1. Exterior check: The technician looks for cracks, loose bricks, or damage to the chimney cap (the metal cover on top). In Longmont’s windy areas near the foothills, chimney caps often get blown off or bent, which lets rain and debris inside. 2. Flue cleaning: Using brushes and rods, they scrub the flue walls to remove creosote and soot. For stubborn buildup, they may use a motorized rotary brush or even a vacuum to suck out debris. 3. Inspection report: After cleaning, they’ll note any issues like excessive creosote (Stage 2 or 3, which is highly flammable), cracks, or a weak draft. If they find problems, they’ll recommend repairs, like repointing mortar or installing a chimney liner /compare/repair-vs-replace-chimney/. 4. Cost: In Longmont, a basic sweep typically costs $120–$250, depending on chimney height and accessibility. If your chimney is tall (common in newer homes on larger lots) or has a complex design, expect to pay more. Always ask for a free estimate /contact/ before booking. Some companies, like ours, offer discounts for off-season sweeps (spring or summer). For the specifics, see about our team and credentials.
Why DIY chimney cleaning is risky in Longmont’s climate
You might see DIY chimney cleaning kits at hardware stores, but they’re not a safe substitute for a professional, especially in Longmont. Here’s why: - Creosote is dangerous: Stage 2 and 3 creosote (the kind that forms in Longmont’s dry winters) is hard as tar and can only be removed with specialized tools. Scraping it with a brush leaves chunks behind that can ignite. - Hidden damage: A DIY sweep won’t catch cracks in the flue liner or mortar joints. In older Longmont homes (like those in the historic downtown area), these issues are common and can lead to carbon monoxide leaks or water damage. - Void warranties: Many chimney manufacturers and insurance policies require professional cleaning to keep your warranty valid. If you skip it and a fire occurs, your claim could be denied. - Safety hazards: Climbing onto roofs in Longmont’s hilly areas (like near the Table Mountain neighborhood) is risky without proper training. A professional has the gear and experience to do it safely. If you’re tempted to DIY, at least do a visual inspection from the ground first /tips/longmont-chimney-self-inspection-guide/. Look for rust on the chimney cap, soot stains on the bricks, or birds nesting in the flue. Learn more about where we work.
How to pick a trustworthy chimney sweep near your neighborhood
Not all chimney sweeps are equal, especially in a town with as many older homes as Longmont.

Next steps after your chimney gets cleaned
Once your chimney is clean, follow these steps to keep it safe and efficient: - Test the draft: Light a small fire and watch the smoke. It should rise straight up the chimney without backing into the room. If you see smoke lingering, there may still be a blockage or poor draft, call your sweep back for a second look. - Check for debris: Remove any ash or creosote chunks from your fireplace and dispose of them outside (never in your trash, creosote is flammable). - Inspect your chimney cap: Make sure it’s secure and free of rust. If it’s damaged, replace it before your next fire. Longmont’s windy spring storms can loosen or bend caps, so check it after heavy winds. - Use only dry, cured wood: Wet or fresh-cut wood makes more creosote. Store your firewood in a dry place (like a covered shed) and burn only wood that’s been split and dried for at least six months. The EPA’s Burn Wise program the EPA's Burn Wise program recommends using wood with a moisture content below 20%. - Schedule your next sweep: Mark your calendar for next year’s cleaning. If you burn wood heavily, consider a second sweep in late winter or early spring.
Chimney trouble spots in Longmont homes
Longmont’s unique climate and housing stock create specific chimney risks: - Dry winters: Low humidity means creosote dries out faster, increasing fire risk. If you’ve had a smoky fire or strong odor, schedule a sweep immediately, don’t wait for your annual appointment. - Older masonry chimneys: Many homes in Longmont’s historic districts (like the downtown area) have chimneys built in the 1920s or earlier. These often have deteriorated mortar or clay flues that need re-lining or repair. If your chimney is over 50 years old, pair your sweep with a Level 2 inspection /compare/chimney-sweeping-vs-inspection/. - Wildfire season: Longmont’s proximity to the foothills means ember risks. Ensure your chimney cap is secure and your roof is clear of debris to reduce fire hazards. - Water damage: Longmont’s spring rains can seep into cracked chimneys, leading to rust or mold. If you notice water stains on your ceiling near the fireplace, your chimney may need waterproofing or repointing. For homes in windy areas (like near the foothills or Table Mountain), also check for loose bricks or mortar after storms. If you’re unsure, a professional inspection /services/ can catch issues before they worsen.
| Usage Level | Recommended Sweep Frequency | Notes for Longmont Homes |
|---|---|---|
| Occasional use (1–2 times/month) | Once per year (before winter) | Ideal for homes with gas fireplaces or rare wood use. Check for creosote stains annually. |
| Regular use (weekly in winter) | Twice per year (fall and spring) | Common for Longmont’s older homes with wood stoves. Dry winters speed up buildup. |
| Heavy use (daily in winter) | Every 4–6 cords of wood or twice yearly | Typical for rural or supplemental-heat homes. Monitor for Stage 2/3 creosote. |
| Older chimney (>30 years) | Annual inspection + sweep as needed | Longmont’s historic neighborhoods often need extra checks for mortar deterioration. |
| After a chimney fire or smoke issues | Immediate sweep + inspection | Critical to prevent recurrence. Dry conditions increase fire risk in Longmont. |
Frequently Asked Questions
My chimney smells like smoke even after lighting a small fire. Is this normal?
No, this isn’t normal. A strong smoke smell when lighting your fireplace usually means creosote buildup, a blockage in the flue, or poor draft. In Longmont’s dry climate, creosote dries out faster, so even a small amount can cause this odor. Schedule a chimney sweep /contact/, don’t wait until winter. If the smell persists after cleaning, your chimney may need a liner or cap repair to improve airflow.
Why does my chimney in Longmont need cleaning if I only use it a few times a year?
Even light use creates creosote, especially in Longmont’s dry winters. The Chimney Safety Institute of America recommends annual cleaning for any fireplace in use, regardless of frequency. Creosote is flammable and can build up slowly, even from occasional fires. Plus, a professional sweep checks for hidden issues like cracks or animal nests that could cause problems before your next fire. If your chimney is older (like many in Longmont’s historic neighborhoods), it’s even more critical to stay on top of maintenance.
Can you burn pine or other softwoods in your fireplace without extra cleanings?
Burning pine or softwoods increases creosote buildup significantly, more than hardwoods like oak or maple. In Longmont’s dry climate, this means faster accumulation of flammable Stage 2 or 3 creosote. If you burn softwoods, you’ll need to sweep your chimney more often (every 3–4 cords instead of 6). Stick to seasoned hardwoods to reduce cleaning frequency and fire risk. Store wood in a dry place and avoid burning treated or painted wood, which releases toxic chemicals.
My chimney is in a rural area near Longmont, does that change anything about cleaning?
Yes, rural chimneys near Longmont often face different challenges than urban ones. Wind and wildlife are bigger issues, birds, squirrels, or raccoons may nest in your flue, and high winds can dislodge chimney caps or loosen bricks. Rural chimneys also tend to be taller or more exposed, making cleaning harder and increasing the risk of creosote buildup. If your chimney is in a windy area (like near the foothills), have it inspected for structural damage after storms. A professional sweep can also check for signs of animal activity and recommend caps or screens to keep pests out.
