Your Broomfield chimney works hard in our cold winters, but hidden damage can turn a cozy fire into a safety hazard. Learn the safe checks you can do yourself and the warning signs that mean it’s time to call in the pros at Mark Robinson Chimney LLC.
What Broomfield homeowners can safely check on their chimney
Start with a visual inspection from the ground using binoculars or a camera on a pole. Look for missing or damaged bricks, cracked mortar joints, or leaning sections—especially after heavy snow or wind common in Broomfield winters. Check the chimney cap for rust or gaps; it should be secure and free of debris. Inside, remove the fireplace screen and shine a flashlight up the flue to spot large obstructions like bird nests or fallen bricks. If you see significant damage or blockages, stop and call a pro. For a deeper look, consider booking a Level 1 inspection with us.
5 early warning signs your Broomfield chimney needs professional attention
Watch for smoke billowing back into the room instead of going up the flue—this often means a blockage or improper drafting. A strong, acrid odor from your fireplace in summer or winter signals creosote buildup or moisture trapped in the flue. Cracks in the chimney crown or flaking paint on the exterior wall near the chimney can indicate water damage. If you hear loud popping or rumbling sounds during a fire, it may mean a dangerous downdraft or flue obstruction. Finally, white residue or efflorescence on bricks points to water seepage—common in Broomfield’s humid springs. Any of these mean stop using the fireplace and call us at Mark Robinson Chimney LLC.
What NOT to DIY on your Broomfield chimney—and why
Never climb onto the roof to inspect or clean the chimney—Broomfield’s unpredictable weather and steep pitches make this a fall risk. Avoid using chemical chimney cleaners sold in stores; they can damage masonry and void warranties. Do not attempt to remove creosote yourself—it’s highly flammable and scraping it improperly can release toxic dust. Never seal cracks with regular caulk or mortar; only use high-temperature refractory cement after a professional assessment. Attempting repairs without proper training risks chimney collapse, carbon monoxide leaks, or fire. Leave these jobs to certified sweeps like our team at Mark Robinson Chimney LLC.
How to safely clean your Broomfield fireplace and hearth area
Begin by removing ashes with a metal shovel and bucket—wear gloves and a dust mask to avoid irritation. Use a shop vacuum with a HEPA filter to capture fine ash particles, especially important in Broomfield’s dry climate where dust spreads easily. Scrub the firebox with a stiff brush and mild detergent, then rinse and dry thoroughly to prevent rust. Inspect the damper for smooth operation and lubricate with graphite powder if needed. Never use a wire brush on ceramic glass doors—it can cause scratches that weaken the glass. After cleaning, check the chimney cap for blockages and ensure the flue is clear before your next fire. For a full sweep, schedule a professional cleaning every 1–2 years.

Frequently Asked Questions
Why is my Broomfield fireplace making a whistling noise when I burn wood?
A whistling sound usually means air is being forced through a narrow or partially blocked flue. In Broomfield’s older homes, creosote buildup or a damaged flue liner can create turbulence. It can also indicate a missing or improperly sized chimney cap. Stop using the fireplace and call us for a Level 1 inspection to check airflow and flue integrity.
What does white chalky residue on my Broomfield chimney bricks mean?
That white residue is efflorescence—mineral deposits left behind when water evaporates from bricks. It signals chronic moisture intrusion, often from a cracked crown or missing flashing. Left unchecked, it weakens mortar and can lead to structural failure. We recommend a full inspection and waterproofing treatment to protect your chimney in Broomfield’s variable climate.
Can I burn pine in my Broomfield fireplace without damaging the chimney?
Pine burns hot and fast, producing more creosote than hardwoods like oak or maple. In Broomfield’s high-altitude climate, creosote builds up faster and increases fire risk. Always season firewood for at least 6 months and avoid burning green or wet wood. For safer burning, use hardwoods and schedule regular cleanings every 1–2 years.
