Learn about Gas Fireplace RepairWhy it matters
Buildup on the flue walls narrows the passage, weakens draft, and is the fuel behind a chimney fire. Regular cleaning clears it.
A clear, sound flue drafts the way it was designed to, so a fireplace or appliance burns cleaner and vents properly.
Keeping water out and the flue intact prevents the masonry decay, leaks, and hazards that quietly develop over the years.
Since 1998
Mister Chimney has worked on chimneys and fireplaces across Missouri since 1998. We serve two metros — St. Louis and Kansas City — with the same approach in both: look at the actual system, explain what we find, and do the work that’s needed rather than a packaged upsell.
We handle wood and gas fireplaces, masonry and prefab chimneys, wood and pellet stoves, and the venting that ties them together, for homes and commercial properties alike.
How it goes
Reach the number for your area or send the form. We’re available 24/7 to take the details.
We look at the actual system — flue, firebox, masonry, cap, and venting — to find what’s really going on.
You get a straightforward explanation of what we found and the choices, before any work starts.

Good to know
The widely recommended practice is a yearly inspection of any chimney or venting system in use, with cleaning added whenever soot or creosote buildup, an animal, or a blockage calls for it. Households that burn often may need cleaning more frequently.

Chimney and fireplace work is scoped from what we find on site, because two systems that look similar can need very different work. We assess the system, explain the options, and are clear about scope before any work begins.
