When your Longmont chimney acts up, start with safe, ground-level checks like inspecting the damper, testing airflow with a piece of paper, and clearing hearth debris. Never climb on the roof or attempt internal repairs yourself. If smoke persists or odors linger, it is time to call a professional services.
Check the Flue Damper Mechanism From the Hearth
Before lighting a fire in your Longmont home, always verify that your flue damper is fully open. Look up into the firebox using a flashlight to ensure the metal plate moves freely and isn't blocked by soot, fallen mortar, or creosote buildup. A partially closed damper prevents smoke from escaping, pushing it right back into your living room. If the handle feels stuck, do not force it with tools. Forcing a rusted linkage can snap internal parts, requiring a professional fix. Review our compare/chimney-sweeping-vs-inspection/ guide to understand when a simple check isn't enough and professional maintenance is required. Learn more about our full list of services.
Test for Draft Flow With a Simple Paper Test
If your Longmont living room smells like a campfire on a warm day, or if smoke fills the room immediately upon lighting, you likely have a negative pressure issue or a cold flue plug. Twist a sheet of paper into a makeshift torch, light the tip, and hold it near the open damper for a few seconds. If the smoke drifts down into the room instead of rising up the flue, you have a cold-air block. Warming the flue by holding the burning paper near the opening for a moment often establishes a proper upward draft before you light your logs. See request a free estimate / contact us.
Clear Hearth Debris and Check the Firebox Interior
Excess ash and unburnt logs can restrict airflow and trap moisture against your firebox walls. Use a metal ash shovel to clear out heavy buildup, leaving a thin one-inch layer of ash if you burn wood, as it helps insulate the bed. Inspect the brick and mortar inside the firebox for deep cracks or missing mortar joints.

Identify Critical Warning Signs That Require Professional Help
While ground-level troubleshooting helps with minor draft issues, certain symptoms demand immediate professional attention. If you notice thick, tar-like creosote lining the flue walls, persistent smoke roll-back, masonry spalling on your exterior brickwork, or water staining on the drywall near your chimney chase, do not attempt a DIY fix. These issues indicate structural failure or severe fire hazards that require specialized tools and safety gear.

Frequently Asked Questions
Why does my Longmont fireplace smoke inside the room when I first light a fire?
A smoky start in Longmont homes usually happens because cold air is trapped in the flue, creating a downward draft. Open a nearby window slightly to equalize pressure, and hold a lit rolled-up newspaper near the open damper for thirty seconds to warm the flue before lighting your main logs.
Can I safely climb onto my Longmont roof to check my chimney cap?
No, climbing onto a roof for chimney checks is extremely dangerous due to steep pitches, slippery tiles, and unexpected Front Range wind gusts. Always keep your feet on the ground and let insured professionals from Michael Johnson Chimney Inc safely inspect your rooftop components.
How do I know if the strange smell coming from my Longmont fireplace is dangerous?
A strong asphalt or campfire odor during humid Longmont weather is typically caused by moisture mixing with creosote deposits inside the flue. While it is a common nuisance smell, it indicates heavy buildup that requires a professional chimney sweeping to eliminate safely and completely.
