A chimney sweep in Frederick, CO removes creosote buildup, debris, and blockages to prevent fires and improve airflow. For first-time homeowners, prioritize a Level 1 inspection ($80–$120) before your first fire of the season, then schedule annual sweeps ($120–$180) to avoid costly repairs. Longmont’s dry winters mean creosote dries faster, sweep sooner if you burn frequently. Always hire a licensed, insured crew like Michael Johnson Chimney Inc to spot hidden issues like cracked flues or water damage we serve Frederick and nearby Longmont neighborhoods.
1. A chimney inspection is a quick, non-invasive check of your flue, liner, and connections to spot cracks, corrosion, or blockages before they cause fires or carbon monoxide leaks.
Frederick’s older homes, especially those near Hwy 7 or in the foothills, often have masonry chimneys built in the 1970s or earlier. These can develop hairline cracks over time, letting rainwater seep in and weaken the structure. A Level 1 inspection (the most basic) costs $80–$120 and takes 20–30 minutes. It’s the first step before your first fire of the season, and it’s cheaper than fixing a chimney fire later. The Chimney Safety Institute of America (CSIA) recommends this for homes with no visible damage. If your inspection finds moisture stains or rust, you’ll need a Level 2 ($150–$200) to check inside the flue. Learn the difference between inspections and sweeps here.
2. Frederick’s dry winters mean creosote builds up faster, schedule your sweep before your first fire, not after.
Longmont’s average winter humidity drops below 40%, and Frederick’s microclimate is even drier. When wood burns, it leaves behind creosote, a sticky, flammable tar that coats your chimney walls. The drier the air, the faster creosote hardens into a brittle, fire-risk layer. Most homeowners think they have time until spring, but the National Fire Protection Association (NFPA) reports that 25% of home chimney fires happen in December and January. If you burn wood regularly, sweep twice a year: once before your first fire (October–November) and again in March. For occasional users, once a year is fine, but if your chimney smells smoky or smoke backs into your room, book a sweep immediately. See our full sweeping process for Frederick homes.
3. DIY chimney tools won’t cut it, here’s why Frederick homeowners should hire a pro (and how to spot a scam).
You’ve seen those $50 chimney brushes at the hardware store, but they’re useless for Frederick’s older masonry chimneys. A proper sweep requires rotary brushes, flexible rods, and a camera inspection to reach every crevice, especially in chimneys with offset bends (common in homes near Table Mesa Drive). A pro will also check for soot buildup in the smoke chamber, a red flag for poor draft. Avoid crews who: - Won’t show you their CSIA certification or insurance. - Charge under $100 for a full sweep (they’re cutting corners). - Guarantee ‘no creosote’ without an inspection. Michael Johnson Chimney Inc offers free estimates and a 30-day warranty on our work. We’ve seen Frederick chimneys with bird nests, fallen leaves, and even dead squirrels, problems DIY tools miss.

4. Your chimney sweep cost in Frederick depends on 3 factors, here’s how to avoid surprises.
Prices vary based on: 1. Chimney height: A 20-foot chimney costs $120–$150; a 40-foot one (common in Frederick’s hillside homes) can run $180–$250. 2. Accessibility: If your chimney is behind a fence or requires a ladder setup (like many homes near Frederick High School), add $30–$50. 3. Extra services: Capping a chimney ($150–$300) or repairing a cracked crown ($200–$500) often saves money when caught early. Smart move: Get a written quote upfront before any work begins. Some crews in Frederick upsell unnecessary repairs, we don’t. See our transparent pricing for Frederick homes.
5. After your sweep, test your fireplace this way to ensure it’s safe (and what to do if it’s not).
Once your chimney is clean: 1. Test your chimney: Burn a small fire (1–2 logs) and check how the smoke behaves. If it backflows into your room, your damper may be stuck or the flue isn’t drawing properly. 2. Check for lingering odors. A faint smoke smell is normal for 10–15 minutes; a strong chemical smell means creosote residue or soot in the smoke chamber. 3. Listen for unusual noises. Crackling or popping sounds could mean hot spots from leftover creosote. If you notice any of these, don’t use the fireplace and call us for a Level 2 inspection.

Frequently Asked Questions
My chimney smells like smoke even after burning just a few logs, why does this happen in Frederick’s dry air?
Frederick’s low humidity causes wood to burn hotter, creating more unburned particles that coat your chimney walls faster. A smoky smell after burning means creosote or soot buildup, even if you haven’t used the fireplace much. Schedule a sweep now before the smell worsens. The EPA’s Burn Wise program recommends burning only seasoned hardwoods (like oak or maple) to reduce creosote. Learn which woods to avoid.
I just moved into a home in Frederick, when should I get my chimney inspected, and how much will it cost?
Inspect your chimney before your first fire of the season, even if it’s summer. Older Frederick homes (built before 1980) often have hidden damage from past neglect. A Level 1 inspection costs $80–$120 and takes 20 minutes. If the inspector finds moisture stains, rust, or cracks, you’ll need a Level 2 ($150–$200) to check the flue lining. We offer inspections for Frederick and nearby Longmont homes.
My chimney has a small crack near the top, will sealing it myself work, or should I call a pro?
Sealing a hairline crack with chimney sealant ($10–$20 at hardware stores) is a temporary fix, but Frederick’s freeze-thaw cycles will widen it over time. A pro can repoint the mortar ($200–$400) or install a chimney cap ($150–$300) to prevent water damage. Ignoring cracks leads to rusted flue liners and structural weakening, costly repairs down the road. See how to spot other DIY-red-flag issues.
I only use my fireplace a few times a year, do I still need an annual sweep in Frederick’s climate?
Yes, even with light use, creosote and soot still build up, especially in Longmont’s dry climate. The NFPA reports that 1 in 3 chimney fires happens in chimneys that aren’t used much. If you fire up your stove fewer than 10 times a year, schedule a sweep once a year. If you stick to seasoned hardwood and keep fires modest, you might go 18 months between sweeps, but always get an inspection before lighting your first fire of the season.
