A chimney isn’t just a vent, it’s a hazard waiting to happen. Creosote buildup, cracked liners, and blocked caps don’t give warnings. You might notice soot stains or a warped cap, but a collapsed chimney liner or damaged brickwork? That’s a job for a licensed sweep. DIY fixes can void warranties or turn your fireplace into a fire risk.
What’s Safe for You to Inspect in Your Chimney (And How to Do It Without Getting Burned)
Before calling a chimney sweep, grab a flashlight and inspect these three spots outside your home: 1) The chimney cap, look for rust, warping, or missing sections. A busted chimney cap lets water and leaves pour down your flue, rotting it from the inside out. 2) The masonry, cracked bricks or missing mortar mean water leaks inside, weakening the structure. 3) The damper, if it’s stuck open or rusted shut, it’s a fire hazard. Safe DIY: Use a garden hose to test for leaks, if water sprays out the damper, you’ve got a crack. For the cap, tighten loose screws if you’re comfortable on a ladder. Never climb on the roof yourself. Broomfield’s windy ridges make falls deadly. Read our no-nonsense checklist for Broomfield homeowners before you start.
3 Red Flags in Your Chimney That Mean ‘Drop Everything and Call a Pro’
These aren’t minor fixes, ignore them and you’re risking a chimney fire or carbon monoxide poisoning. 1) Strong, sweet-smelling smoke when burning wood means creosote is clogging the flue. 2) Rust stains on the fireplace hearth or walls signal a leaking flue or corroded liner. 3) Birds or critters nesting in your chimney block airflow and create fire hazards. Pro move: A licensed sweep in Broomfield can remove nests safely and check for hidden damage. See our guide on critter-proofing chimneys, it’s not a DIY job. If you see any of these, stop using the fireplace and call Mark Robinson Chimney LLC for an inspection. Our Broomfield team handles emergencies.
DIY ‘Fixes’ That Will Either Get You Hurt or Turn Your Chimney Into a Hazard
Some ‘quick fixes’ void warranties, start fires, or get you sued. Never: 1) Scrape creosote with a wire brush, it sends flammable dust into your home. 2) Patch cracks with mortar without removing damaged bricks first. 3) Ignore a sagging chimney, it’s a structural failure waiting to happen. 4) Install a new liner unless you’re CSIA-certified. Why? Improper lining can trap gases, causing CO poisoning. Broomfield’s older homes often have hidden issues like clay tile liners that crumble when disturbed. Compare DIY risks vs. pro work here. If your chimney’s over 20 years old, assume it’s got hidden problems, get a Level 2 inspection from a pro. See our pricing for Broomfield inspections.
Step-by-Step: How to Prepare Your Chimney for a Broomfield Sweep (Do This Before They Arrive)
A pro sweep goes faster and safer if you prep. 1) Clear the fireplace, remove glass screens, decor, and store firewood at least 10 feet away. 2) Move pets and kids, sweeping creates dust and noise. 3) Open windows in the room to ventilate. 4) Point out issues, show the sweep any cracks, rust, or odd smells. Pro tip: If your chimney’s taller than 30 feet (common in Broomfield’s hillside homes), mention it, they’ll bring the right tools. See how to ready your home for a sweep. Bonus: If your fireplace smells like gas after sweeping, it’s a flue blockage, don’t light it until a pro checks it. Learn more about gas vs. wood fireplaces.

Frequently Asked Questions
My fireplace stinks like gas after burning wood, should I panic?
No, you should panic. That smell means carbon monoxide is sneaking into your home from a blocked or cracked flue. Shut down the fireplace, crack windows, and don’t breathe it in. A Level 2 inspection will find hidden cracks or debris. Run our Broomfield chimney smell checklist first. If you wake up with a headache or feel sick, call 911 immediately, then call a chimney sweep.
Can I light a fire after a sweep if Broomfield’s winds are howling?
Yes, but only if the sweep gives you the green light, and you follow these rules: 1) Burn only dry, seasoned wood (Broomfield’s dry air helps, but wet wood creates more creosote). 2) Keep fires small to avoid overheating a newly cleaned flue. 3) Watch for smoke backing up, if it’s thick or smells acrid, the flue isn’t clear yet. Learn how often you should sweep in Broomfield to avoid this next time. If the sweep didn’t check for hidden blockages, ask why.
Crumbling bricks at your chimney’s base aren’t just ugly, they’re a sign your foundation’s in trouble. Is it an emergency? That depends on how fast they’re falling apart.
Not yet, but it’s a ticking time bomb. Crumbling masonry means water’s eroding the mortar, and once bricks start falling, the flue can collapse. DIY fix? No, patching with mortar alone won’t stop the leak. Pro fix: Repointing or tuckpointing seals the cracks and redirects water. In Broomfield’s freeze-thaw cycles, this job must be done before winter. See our guide on masonry repairs. If you see rust stains on the ceiling, the leak’s already inside, call us immediately for an emergency inspection. Our Broomfield team handles urgent repairs.
