The Short Answer: At Least Once a Year
If you use your fireplace regularly through Westminster's cold Colorado winters, the National Fire Protection Association (NFPA 211) recommends scheduling a professional chimney sweep and cleaning at least once per year. That guidance applies to wood-burning fireplaces, gas inserts, wood stoves, and any other solid-fuel appliance that vents through a chimney. Annual cleaning removes the creosote, soot, and debris that accumulate inside your flue before they reach dangerous levels.
Why Westminster's Climate Makes Annual Cleaning Even More Important
Westminster sits at over 5,000 feet elevation with genuine four-season weather. From October through March, homeowners lean heavily on their fireplaces and heating appliances, burning considerably more wood than households in milder climates. More burning means faster creosote accumulation. Creosote — the tar-like byproduct of incomplete wood combustion — coats your flue liner in layers. Stage 1 creosote is a light, flaky deposit that brushes off easily. Stage 2 becomes a harder, tar-like coating, and Stage 3 is a thick, glazed substance that is extremely difficult to remove and highly combustible. Westminster homeowners who burn frequently through a long heating season can move through Stage 1 into more dangerous territory faster than they may realize.
Colorado's freeze-thaw cycles also play a role. Moisture that enters a chimney — whether from rain, snow, or condensation — interacts with creosote deposits and accelerates liner deterioration. Keeping the flue clean and dry reduces this risk significantly.
Signs You May Need Cleaning Sooner Than Your Annual Appointment
- You notice a strong, unpleasant odor coming from your fireplace, especially in warm weather or humid conditions
- You see black soot or debris falling into the firebox
- Your fires are harder to start or don't burn as efficiently as they used to
- Smoke backs up into your living space instead of drawing properly up the flue
- You've been burning more than three cords of wood in a single season
If any of these apply, don't wait for your annual appointment. Reach out to Simmons Brothers Chimney Sweeps at (720) 881-0206 to schedule a mid-season cleaning before creosote buildup becomes a fire hazard.
What Happens During a Professional Chimney Cleaning?
Our technicians arrive equipped with professional-grade rotary brushes, fiberglass extension rods, and commercial HEPA-filtered vacuum systems. We lay protective drop cloths around your fireplace to contain all soot and debris, then systematically clean from the firebox up through the flue to the chimney cap. After cleaning, we inspect accessible portions of the chimney for visible damage and provide a written condition report. The entire process is designed to leave your home cleaner than we found it.
We service all chimney types found throughout Westminster and the surrounding area, including traditional masonry fireplaces, prefabricated factory-built units, and gas insert systems. Neighborhoods like Shaw Heights and Hyland Hills are home to a mix of older masonry chimneys and newer prefab systems — our team handles them all.
Pair Your Cleaning With an Inspection for Complete Peace of Mind
A cleaning removes what's there now. A chimney inspection tells you the condition of what's underneath. Pairing both services in a single visit is the most efficient way to ensure your chimney is safe, functional, and ready for the season ahead. Our Level 1 inspection covers all accessible areas of the chimney structure, while our Level 2 inspection adds a high-definition camera scan of the full flue interior — ideal if you haven't had the chimney inspected in several years or if you've recently purchased your Westminster home.
