Denver’s Most Meticulous Chimney Sweep for Safer, Cleaner Fireplaces

That persistent campfire odor is usually trapped creosote or soot reacting with humidity from Denver’s frequent evening dew—especially near Sloan’s Lake or along the Platte River. Our technicians don’t just sweep; we apply a proprietary deodorizing treatment and seal any gaps in your flue to stop the stench at its source.

A hairline crack in your flue liner lets toxic gases—including carbon monoxide—seep into your home’s walls, and Denver’s subzero nights turn that moisture into ice, widening the crack by spring. We pressure-test liners and rebuild them with heat-resistant mortar to eliminate the risk entirely.

Check for black, tarry buildup on your damper or a layer of soot thicker than a Denver Post—if you see either, your chimney is overdue. We also recommend a Level 2 inspection if you’ve recently renovated or added a new stove, as Denver’s building codes require it.

Many chalk up water stains to roof issues, but a leaking chimney—especially on older brick stacks in Montbello—often means failed flashing or a cracked crown. We use infrared moisture meters to pinpoint leaks and restore waterproof barriers before mold or structural rot sets in.

A Level 1 is a visual sweep of accessible areas, while a Level 2 includes a camera inspection of the entire flue—critical for Denver homes with complex layouts or recent fireplace upgrades. We perform both in-house to ensure no hidden damage goes unnoticed.

Yes, but it requires underpinning the foundation or installing helical ties—common fixes for older stacks in Baker or RiNo. We partner with structural engineers to stabilize leaning chimneys without tearing into your home’s interior.

Those white stains are efflorescence, caused by water dissolving salts in the mortar and depositing them on the surface—especially prevalent in Denver’s alkaline soil. We repoint affected joints with low-salt mortar and apply a breathable sealant to prevent recurrence.

You can safely use your fireplace 24 hours after a sweep, but we recommend waiting 48 hours to let any residual dust settle. For gas inserts, we perform a post-sweep pressure test to ensure no combustion byproducts are leaking into your living space.
