Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Call (336) 863-3889 for a free estimate and a written price before anything gets scheduled.
We work all over the Denver metro, from the Denver Square foursquares in Capitol Hill to the mid-century ranches east toward Aurora. Ruben Castellano and his crews know these chimneys. They know what a century of Colorado freeze-thaw cycles does to single-wythe brick masonry. They know what altitude does to a wood fire. And they’ll tell you plainly whether your flue is safe to use tonight or needs work before you light anything.
Why Alcott Chimney Sweep Is Denver’s Preferred Chimney Inspection Company
Denver homeowners call us because we tell them the truth and prove it with camera footage. Every inspection comes with a photo report you can see with your own eyes. Nothing gets recommended that you cannot verify on the screen. That matters in Denver, where old brick and altitude combine to create flue conditions that a quick visual once-over misses entirely.
Since 2002, Alcott has operated as part of the Threshold Group family of home-service companies. Every technician who arrives at your Denver door has passed a background check and identity verification before ever stepping on your property. You’ll know the technician’s name and see their photo before we arrive. They’ll show a photo ID badge at the door, every time, no exceptions. That’s the Threshold Standard, and it’s not optional.
We answer the phone with a live person around the clock. If you smell smoke at 11 p.m. on a cold Denver night and aren’t sure whether it’s a chimney fire or a bad draft, you’ll talk to a human being, not a voicemail. And every inspection comes with a written price before any work starts, plus a 365-Day Done Right Promise on any repair we recommend.
Fireplace Inspection in Denver
Fireplace Inspection in Denver means evaluating the firebox, damper, smoke chamber, and flue liner for damage, creosote buildup, and clearances to combustible framing. A Level 1 fireplace inspection in Denver runs $189 – $249 when the chimney is being used as-is with no changes. At 5,280 feet, Denver fireplaces burn oxygen-starved compared to sea level, so incomplete combustion produces more creosote per fire than the same wood would in lower-altitude cities like Pueblo or Grand Junction. That means a fireplace that looked clean in August can show concerning buildup by January.
What a Level 1 Inspection Covers
A Level 1 inspection checks the accessible portions of the fireplace and chimney: firebox condition, damper operation, visible flue interior from above and below, and the exterior masonry for obvious cracks, spalling, or missing mortar. We’re looking for the specific failure patterns Denver homes present: freeze-thaw crown cracking, deteriorated mortar joints, and creosote that has glazed over from low-oxygen burning.
When Denver Homeowners Need One
Book a Level 1 inspection before the first fire of the burning season, and again if you’ve burned more than a cord and a half of wood or noticed any smoke backing into the room. In Denver, the RAQC no-burn calendar concentrates fireplace use into short bursts after bans lift. A cold flue loaded with green or damp wood can flash-deposit glazed creosote in a single evening. Annual inspection is not a suggestion here; it’s the safe interval.
Chimney Inspection Services in Denver
Chimney Inspection Services in Denver range from a quick Level 1 check to a full Level 3 inspection when hidden damage is suspected. A Level 2 inspection in Denver runs $289 – $389 and adds interior camera scanning of the flue from top to bottom, which is what you need after any chimney fire, major weather event, or real estate transaction. The camera is the difference between guessing and knowing.
Camera Inspection and Flue Verification
Our camera inspection makes the flue interior visible in real time. We look for cracked flue tiles, missing mortar, gaps where a liner was never installed, and the glazed creosote that a standard brush cannot remove. In homes with no liner, like many of the Craftsman bungalows in Congress Park and Park Hill, the camera often reveals smoke-chamber damage hidden behind a century of soot. You’ll see the footage yourself. You’ll understand exactly what’s there.

Real Estate and Presale Inspections
Buying or selling a home in Denver usually triggers a Level 2 inspection. Mortgage lenders and insurance underwriters increasingly request camera documentation of the flue condition before they’ll sign off. We provide a written report with photos suitable for closing documents. If you’re buying a 1920s bungalow near Washington Park or a ranch in Wheat Ridge, call us before the inspection contingency expires. We’ll give you the facts and a written quote for anything that needs repair.

Trusted Brands We Service in Denver
Alcott Chimney Sweep carries and installs professional trade materials, not box-store substitutes. When a Denver inspection finds a liner that needs replacement, we specify DuraFlex systems. When a crown needs repair or a flue needs resurfacing, we work with HeatShield and Olympia Chimney components. We also service and replace Famco and Copperfield caps and dampers. Because we stock these parts locally at our Denver office, repairs usually don’t wait on a shipping delay from a distributor two states away.
Common Chimney Inspection Problems We See in Denver Homes
- No-burn-day creosote bursts: After a multi-day RAQC ban lifts, homeowners light a cold, uncoated flue with green or damp wood. The result in a Denver chimney is often hard, glazed creosote flash-deposited in a single evening, the hardest type to remove and the most likely to fuel a chimney fire.
- Altitude draft starvation: At 5,280 feet, fires burn with less oxygen than they would at lower elevations. Incomplete combustion pushes first-degree creosote into second- and third-degree glaze faster than in lower-altitude Colorado cities, even when the fireplace is only used a handful of nights each season.
- Century-old unlined stacks: The single-wythe brick chimneys common in Park Hill, Congress Park, and Capitol Hill rarely have a liner. A century of freeze-thaw cycling leaves spalled mortar joints and cracked crowns. Moisture reaches the smoke chamber, and the hidden flue damage only shows up on a Level 2 camera inspection.
- Cracked crowns and displaced tiles: Denver’s heavy, wet spring snows and winter freeze-thaw cycles collapse or shift uncapped flue tiles on older masonry chimneys. A cracked crown lets water into the chimney structure, which accelerates spalling and can lead to expensive rebuilds if ignored.

FAQs About Chimney Inspection in Denver
Denver’s altitude is the main reason. At 5,280 feet, the air is thinner, so wood fires burn with less oxygen and combustion is less complete. Incomplete combustion produces more creosote per fire than you’d get at lower elevations like Kansas City. Add in Denver’s RAQC burn bans, which concentrate fireplace use into short bursts after restrictions lift, and you get fast, hard creosote deposits. If you’re burning wood regularly, plan on a more frequent sweep interval than your brother needs, call (336) 863-3889 to set one up.
Once a year, even if you only burn during the legal windows after RAQC no-burn days lift. The burn-ban pattern means your flue cycles from cold to hot in short, infrequent bursts, which is exactly the condition that deposits the hardest glazed creosote fastest. A few nights of legal burning in November can leave a flue with third-degree glaze by December. Annual inspection is the safe minimum in Denver. Call (336) 863-3889 and we’ll get you on the schedule.
Third-degree creosote is the hardest form of creosote: a dense, glazed, tar-like coating that has hardened into a shiny black enamel on the flue walls. It shows up in Denver more often because altitude-thinned air causes incomplete combustion, and the burn-ban calendar produces cold flues lit in short bursts with less-than-ideal wood. Third-degree creosote generally cannot be removed with a standard brush and requires chemical treatment or mechanical removal. If an inspection finds it, we’ll show you the camera footage and give you a written recommendation before any work starts. Call (336) 863-3889.
On an unlined century-old chimney, a Level 2 inspection checks the interior brick surface for cracks, gaps, and spalled mortar; the condition of the crown and cap; whether the smoke chamber has any hidden damage where moisture has penetrated; and whether the flue can safely vent the appliance it currently serves. We’ll run the camera up the flue so you can see exactly what’s there. Most Park Hill and Congress Park chimneys of this age need some form of liner or resurfacing. We’ll quote you a written price and never push work you cannot verify on screen. Call (336) 863-3889 for a free estimate.
Yes. Rain is only part of the problem. Denver’s heavy, wet spring snows and freeze-thaw cycles are the bigger threat. An uncapped flue lets snow and moisture into the chimney, which freezes, expands, and spalls the brick and mortar from the inside out. Caps also keep out birds, squirrels, and debris that can block the flue and create a carbon monoxide risk. We install Famco and Olympia Chimney caps, and the cost is modest compared to the masonry repairs an uncapped chimney eventually needs. Call (336) 863-3889 for a quote.
