Chimney Cleaning in Colorado
Need chimney cleaning? Donovan Chimney & Fireplace serves Denver, Fort Collins & Colorado Springs with 25+ years of experience. Family-owned since 1998 · Licensed & insured · Open 24/7.
About This Service
A professional chimney cleaning removes the creosote, soot, and debris that every wood fire leaves behind in your flue. Creosote is highly flammable — it's the fuel in nearly every chimney fire — and in Colorado, where fireplaces run hard from October through April, it builds up faster than most homeowners realize.
Our sweeps use rotary rod systems and HEPA-filtered vacuums, so the work is thorough at the flue and spotless in your living room. We inspect as we clean, which means you also get an honest condition report, not just a clean flue.
Signs You Need Chimney Cleaning
- It's been more than a year (or a cord of wood) since your last sweep
- Smoke drifts into the room instead of drawing up
- A campfire smell lingers even when nothing is burning
- Black flakes or tar-like glaze visible inside the flue
How Our Cleaning Process Works
We protect your home first — drop cloths, HEPA vacuum staged, glass doors or opening sealed.
Rotary rods and brushes work the full flue length while the vacuum captures everything at the bottom.
Firebox, smoke shelf, and damper area are cleared and detailed by hand.
You get a verbal-plus-photo condition report before we leave — clean flue, honest findings.
Why It Matters for Safety
Creosote is the fuel in most chimney fires, and Stage 3 glazed creosote can ignite at flue temperatures a hot fire reaches routinely. The National Fire Protection Association's Standard 211 calls for annual inspection and cleaning as needed — along the Front Range, where fireplaces work half the year, that guidance is the floor, not the ceiling.
Maintenance Tips From Our Technicians
- Burn seasoned hardwood (under 20% moisture) — wet wood is the fastest creosote maker.
- Keep fires hot and active; smoldering overnight burns deposit the most glaze.
- Watch your cap screen through winter — creosote caking there chokes draft.
- Book annual service in spring or summer, before the October rush.

Frequently Asked Questions
How often should a chimney be cleaned in Colorado?
The NFPA recommends annual cleaning and inspection. If you burn regularly through a Front Range winter — or burn pine, which creosotes quickly — once a year is the safe baseline, and heavy burners often benefit from a mid-season check.
How long does a chimney cleaning take?
A standard sweep takes about 45 minutes to an hour. If we find heavy glazed creosote it can take longer, because glaze needs mechanical removal rather than simple brushing.
How soon can you come out?
Routine appointments are usually available within the week, and our 24/7 emergency line handles the situations that can't wait. October and November book fastest — spring and summer scheduling is easiest.
