Six things homeowners notice, and the part behind each one
Most calls start with something you can see or smell. Here is where it usually comes from.
Smoke rolls back into the roomSmoke chamber and draft
At 5,280 feet there is less air pressure pushing exhaust up the flue. A corbeled smoke chamber with stepped ledges and carbon buildup slows the draft enough to spill smoke into the room.
The fix: smoke chamber parging, draft analysis and airflow correction.
See chimney draft analysis
Water stain on the ceiling beside the chimneyFlashing
Hail and high winds separate counterflashing from the masonry. The gap is invisible from the ground, and water tracks down the framing before it shows on the ceiling.
The fix: reset or replace the step and counter flashing at the confirmed entry point.
See chimney flashing repair
White crusty bloom on the brickEfflorescence and the moisture path
Water moving through masonry carries soluble salts to the outer face and leaves them behind as it evaporates. The stain is what the water left, not the problem itself.
The fix: moisture assessment first, then removal and sealing of the real entry path.
See efflorescence removal
Brick faces flaking offSpalling from freeze and thaw
Water trapped in brick expands about 9 percent every time it freezes. Front Range mornings below freezing and afternoons in the 60s repeat that until the brick face pops off.
The fix: confirm whether the spalling is active or stabilized, then replace brick and stop the moisture source.
See spalling brick repair
Soot smell on warm humid daysDeposits and negative pressure
Warm humid air meets creosote deposits in the flue, and a house under negative pressure pulls that air down into the room instead of up the chimney.
The fix: confirm the odor source, then clean, seal or correct the pressure path.
See fireplace odor removal
Shiny black tar on the flueStage 3 creosote glaze
Glazed creosote is hardened tar on the liner wall. A brush slides straight over it, which is why a chimney can be cleaned and still carry a heavy deposit.
The fix: a chemical modifier applied first, then mechanical removal and a flue check.

The parts of a chimney





Everything your chimney and fireplace could ever need
AR Chimney Pros handles the full range, from a routine sweep to full structural rebuild.
Every service below is handled by our in-house team out of our Lakewood location.
01Chimney cleaning and sweeping
Creosote, the tar like byproduct of wood combustion that coats flue walls in progressive stages, is the core target of every cleaning visit. We remove it at every stage, including hardened glaze deposits that require chemical treatment before brushing.
02Chimney inspection
We perform all three NFPA 211 inspection tiers. NFPA 211 is the National Fire Protection Association standard that defines minimum safety requirements and inspection levels for chimney systems. Tier 1 covers accessible areas, tier 2 includes camera scans of the flue interior, tier 3 involves targeted demolition to access hidden damage. Every tier is available here, no need to call a separate company for camera work.
03Chimney repair
Full repair services include crown repair and custom crown installation, mortar repair and repointing, spalling brick repair, flashing repair, smoke chamber repair, chimney relining, and liner installation. We also handle efflorescence, the white mineral deposits that signal active moisture movement through masonry, with both diagnostics and removal.
04Waterproofing and leaks
Leak diagnostics, flashing repair, waterproofing, surface sealing, and emergency leak repair are all available. We trace moisture to the source before applying any fix. Sealing without diagnosis is a short term patch. We don't work that way.
05Fireplace services
Fireplace cleaning, gas fireplace inspection and repair, gas log installation, fireplace odor removal, smart home fireplace integration, and custom mantel installation. The firebox, the enclosed combustion chamber where fuel burns, gets a thorough inspection on every fireplace service call.
06Emergency and specialty
Post fire chimney inspection, emergency storm damage repair, emergency spalling brick repair, carbon monoxide safety inspection, animal removal, and bird nest removal. We also cover chimney draft analysis and airflow correction for homes with persistent smoke or downdraft problems.
07Commercial chimney services
Commercial chimney cleaning, exhaust cleaning, flue cleaning, and commercial repair. We serve property managers, HOAs, and multi unit buildings across the Denver Metro.
The Front Range is hard on chimneys
Chimney service in Lakewood and the Denver Metro isn't the same as anywhere else in the country.
The Front Range, the populated corridor running along Colorado's eastern edge of the Rockies, sees dramatic temperature swings between seasons. Mornings can drop below freezing in April while afternoons hit the 60s. That expansion and contraction cracks mortar joints faster than in milder climates. It loosens chimney crowns. It pries apart flashing seals.
Add Denver Metro's altitude, around 5,280 feet and climbing into the foothills, and combustion dynamics shift. Draft behavior inside a chimney flue (the interior passage that channels exhaust gases out of the home) is affected by ambient air pressure. That's why some Lakewood homes burn cleanly one season and pull smoke back into the living room the next, even with nothing visibly wrong.
We've built our service approach around these local realities. What works in Houston or Atlanta doesn't always translate here.

- 5,280 ft
- Elevation at our Lakewood dispatch
- 6 months
- Length of a Colorado heating season
- 3 stages
- Of creosote we test for on every visit
A 20 person team. One Lakewood dispatch. No middlemen.
Every job is handled by our own crew, no subcontracting, no franchise handoffs.
Our dispatch is at 12640 W Cedar Dr, Unit 7 in Lakewood, inside the metro rather than on the edge of it.
AR Chimney Pros runs 20 crew members out of that single location, so training stays consistent and standards don't drift from job to job.
The systems in Denver Metro homes vary widely. Older Lakewood ranches have different firebox and flue configurations than new builds in Aurora or foothills homes in Evergreen. Relining, crown fabrication and gas fireplace diagnostics are all in-house.

What a visit looks like
- 1You describe what you are seeing and we book a window.
- 2We lay floor protection before anything comes out of the firebox.
- 3We photograph the crown, cap, flashing, liner and firebox, then walk you through what we found.
- 4You get the findings in writing, with repairs quoted separately from the visit.
