Avoid ‘chimney rockets’ or chemical cleaners, they’re illegal in Colorado and can damage flue liners, voiding your warranty. Never ignore a cracked flue liner, even if it’s not leaking yet, high-altitude fires can push debris through micro-fractures, clogging your system.

Frequently Asked Questions
My Denver fireplace smells like gas when it’s not in use, what’s causing this and how do I fix it?
No, this is never normal in Denver’s high-altitude homes. It means your gas line or venting is leaking carbon monoxide or unburned gas. Shut off the fireplace immediately, open windows, and call Coral Chimney Co for an emergency inspection. anchor service areas include gas fireplace diagnostics. Never ignore this. CO poisoning is silent and deadly.
White powder near my chimney, is it normal soot or a sign of a bigger problem?
That’s likely efflorescence, a mineral buildup from moisture seeping through your chimney’s bricks. While not toxic, it’s a clear sign of water damage. Denver’s freeze-thaw cycles worsen cracks over time. Scrape a small test area: if the brick beneath is soft or crumbling, you need a chimney repointing before winter. anchor explains how to check for deeper issues.
Can I still use my fireplace after a sweep if the flue still has leftover soot?
Only if it’s light, dry soot (Stage 1 creosote) and your sweep confirmed the flue is clear. Heavy residue or glossy buildup means more cleaning is needed, burning with partial blockages creates toxic creosote gases and risks chimney fires. Denver’s dry air makes creosote harden faster, so wait for a professional go-ahead before relighting. anchor shows how to spot unsafe levels.
