Use a flashlight, mirror, and chimney brush to spot problems early, but leave heavy cleaning and repairs to licensed pros. Most chimney sweeps in Broomfield charge $120–$250 for a full inspection and cleaning, but catching issues yourself can save you hundreds in repairs. If you see soot stains on the ceiling or a strong smoke smell, call a pro immediately, those are red flags for a failing chimney.
What’s a chimney inspection, and why does Broomfield’s dry heat and high winds demand one every year?
A chimney inspection is a hands-on check of your flue, liner, damper, and roof penetration to spot structural damage, blockages, or safety hazards. In Broomfield, where winter temperatures drop below freezing and humidity swings are brutal, moisture and creosote buildup happen faster than in drier climates. If your chimney isn’t sealed properly, water can seep into masonry, freeze, and crack the flue, leading to costly repairs or even a chimney fire. The Chimney Safety Institute of America (CSIA) recommends inspecting your chimney annually before the heating season, but if you burn wood frequently, you should check it every 3–4 months. Start by turning off the fireplace, putting on gloves, and grabbing a flashlight, mirror, and chimney brush. Most homeowners in Broomfield skip the inspection until they smell smoke indoors or see soot stains on the ceiling, don’t wait that long. For a full checklist of what to inspect, see our no-nonsense guide.
How to check for creosote buildup (the #1 fire risk in Broomfield chimneys)
Creosote is the sticky black gunk left when wood doesn’t burn clean, and it’s the #1 cause of chimney fires in Colorado. In Broomfield, where many homes use fireplaces for supplemental heat, creosote builds up faster if you burn softwoods like pine or if your chimney isn’t hot enough to burn it off. To check for creosote, shine a flashlight up the flue and look for glossy black streaks (Stage 2) or hard, crusty deposits (Stage 3). Stage 3 creosote is highly flammable and requires professional removal, most chimney sweeps in Broomfield charge an extra $50–$100 for heavy buildup. If you see even a thin layer, schedule a sweep before winter. The EPA’s Burn Wise program the EPA's Burn Wise program recommends burning only seasoned hardwoods to reduce creosote, but even then, you’ll need a professional cleaning at least once a year.

What to do if you find cracks, rust, or animal nests in your Broomfield chimney
Cracks in the flue or masonry, rust on metal components, or animal nests (like those left by squirrels or birds) are all signs your chimney needs professional attention. In Broomfield, where older homes with brick chimneys are common, mortar joints often deteriorate due to freeze-thaw cycles. Use a mirror to inspect the flue from the bottom, if you see daylight through cracks or rust spots, that’s a fire hazard. Birds, squirrels, or raccoons clogging your flue stop airflow and let creosote build up, fire waiting to happen. If you see any of these red flags, don’t fix it yourself, call a pro. Chimney relining or repointing in Broomfield typically costs $1,200–$3,500, but catching cracks early can save you thousands. For a breakdown of repair costs, check our pricing guide, and if you’re unsure, call a licensed chimney sweep for a free estimate before the problem worsens. See our guide on spotting animal damage to avoid costly surprises.
How to test your chimney’s draft (and why a weak draft means danger in Broomfield)
A working draft pulls smoke straight up and out of your chimney, no backdrafts, no stalling. If your fireplace smokes indoors or the fire flickers weakly, your draft is failing, often due to a blocked flue, damaged liner, or poor chimney height. In Broomfield, where many homes have short chimneys or are surrounded by taller buildings, draft issues are common. Test your draft by holding a lit newspaper near the fireplace opening. If smoke shoots straight up and out, your draft is solid. If not, something’s blocking it. If it lingers or drifts sideways, you’ve got a problem. Weak drafts can push carbon monoxide into your home, so don’t ignore it. Most chimney sweeps in Broomfield can adjust dampers or recommend a chimney cap to improve airflow for $150–$300. Learn how to fix draft problems safely before your next fire.
When should you call a Broomfield chimney sweep, and how to spot a cut-rate ‘pro’ who’ll make things worse?

Avoid companies that pressure you into unnecessary repairs, stick with local crews who provide warranties and clear explanations. See our guide on choosing a chimney sweep to avoid scams.

What to avoid during a DIY chimney inspection (Broomfield-specific mistakes)

Never use a pressure washer on your chimney, as it can damage masonry and force water into cracks.

Frequently Asked Questions
Your Broomfield fireplace smells like smoke even when it’s cold, what’s really burning in there?
A smoky smell when the fireplace is off means creosote or soot has built up in the flue or is leaking into your home. In Broomfield, this often happens when chimneys aren’t cleaned often enough or when dampers don’t seal properly. Check the damper first, if it’s stuck open, cold air can pull soot into your living space. If the smell persists, schedule a chimney sweep immediately. Learn how to test your damper before calling a pro.
White powder around your fireplace isn’t just dust, could it be dangerous ash or something else?
That white powder is likely calcium carbonate, a byproduct of water seeping into your chimney and reacting with the masonry. In Broomfield’s humid summers and freezing winters, this happens often in older brick chimneys. While it’s not immediately dangerous, it’s a sign your chimney needs waterproofing or repointing. Ignoring it can lead to cracks and water damage. See our guide on chimney waterproofing to protect your investment.
My Broomfield chimney has a rusted metal liner, can I just replace the liner myself?
No, replacing a chimney liner is a job for a licensed professional. In Broomfield, many older homes have clay or metal liners that must be installed to exact specifications to prevent carbon monoxide leaks. A DIY liner job can collapse or fail, putting your home at risk. Most chimney sweeps charge $800–$2,000 for liner replacement, but it’s worth the cost to avoid a deadly gas leak. For a list of chimney repairs you should never DIY, some jobs are safer left to the pros.
How do I know if my Broomfield chimney has a leak, and what should I do about it?
Look for water stains on the ceiling near the fireplace, damp masonry, or efflorescence (white crust) on the chimney bricks. In Broomfield, leaks often start at the roof flashing or cracked mortar. If you see any of these signs, call a chimney sweep to inspect the flue and recommend repairs. Water damage can weaken your chimney’s structure, leading to costly repairs. Learn how to spot and fix leaks before they worsen, acting fast saves money.
