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.

AfterFireplace Services in Denver: Written Price Before Work Starts, Camera Evidence Included
Fireplace service in Denver means dealing with two forces most cities don’t have: a high-altitude burn that produces creosote faster, and a winter air-quality program that legally limits when you can light a fire. A typical fireplace cleaning in Denver runs $189-$289, a damper repair $240-$480, and a firebox rebuild $900-$2,400 depending on firebox size and mortar condition. Every job we do includes an NFPA 211 Level 2 camera scan, a written price before any work starts, and a photo record when we’re done. Call (980) 580-8641 to book.
Key Takeaways:
- Denver’s RAQC burn-day restrictions mean your fireplace has a limited legal burn window each winter. A clean, efficient flue protects that window.
- Pre-1950s Denver homes often have oversized coal-era flues that accelerate glazed creosote formation, even with annual sweeping.
- Freeze-thaw cycling across 60+ threshold crossings per year spalls brick and mortar faster here than almost anywhere in the country.
- We write the price down before work starts. No call for a quote, no post-inspection surprise.

Fast, Reliable Fireplace Services Across Denver
If you live in Denver, you already know the drill on winter evenings: check the RAQC burn status, then decide whether tonight is a fire night. What you may not know is how much a dirty or inefficient fireplace is quietly costing you on the days you can legally burn. At 5,280 feet, wood fires burn cooler and less completely than they do at sea level. That thinner air means more unburned particulate heading up your flue, condensing as creosote faster than the same fire would produce in, say, Chicago or St. Louis. Our techs work in Denver neighborhoods every week: Washington Park, City Park West, Montclair, Platt Park, LoDo. When you call, a real person answers, 24/7. When a crew is dispatched, you get a text with the tech’s name before they arrive. Call (980) 580-8641.
We don’t ask you to trust a flashlight peek and a verbal “looks fine.” We run a camera down the flue on every visit, and you get the photos. That’s been our standard since 2009, and it’s codified as Clause 4 of the Haven Standard. You see what we see. That changes how the conversation goes after the inspection.
Why Emberly Chimney Cleaners Is Denver’s Preferred Fireplace Services Company
Homeowners in Denver’s older neighborhoods have a specific problem: their houses were built for coal, not wood. The fireboxes are shallow, the flues are oversized, and the mortar has been through 70 to 100 years of Chinook-driven freeze-thaw cycles. We’ve worked on enough of these to know what we’re going to find before we even set up the ladder in a Capitol Hill brick bungalow or a Congress Park four-square. That local pattern recognition means less time diagnosing, more time fixing, and a lower bill for you.
Our Fireplace Services team has completed more than 38,000 inspections and cleanings since 2009. Every single one included a written price before work started and a documented photo record when it was done. We’re independently owned and operated under the Haven Standard, led by Corrine Halstead. Our techs are background-checked, uniformed, and carry their license information on every job. We don’t send a salesperson with a clipboard. We send a sweep with a camera, a brush, and the tools to fix what the camera finds.
Denver homeowners read reviews before they call. We get that. Read our three-star reviews as closely as our five-star ones. What you’ll see is a company that occasionally makes a scheduling mistake and then fixes it, not a company that hides behind a call center. That matters when you’re trusting someone to assess whether your chimney liner is safe or your damper is about to fail.

Gas Fireplace Service
A gas fireplace in Denver runs anywhere from a vented log set in a converted coal firebox to a direct-vent insert with a sealed glass front. Both need annual service. Thermocouples fail, burner ports clog with dust, and venting gets obstructed. Gas service in Denver typically runs $149-$289 and includes cleaning the burner assembly, checking gas connections, and verifying proper draft. If you have a gas insert in a pre-war home, we also inspect the original chimney chase around the vent for moisture intrusion. Denver’s freeze-thaw cycles are hard on any exterior masonry, whether there’s a fire in it or not.
Wood Burning Fireplace
Wood burning fireplaces in Denver are governed by the RAQC’s mandatory curtailment program. You can only burn on designated green days during the heating season. That’s not a suggestion: it’s a legal restriction with fines attached. What that means for you is that every green day matters. If your flue is half-choked with second-degree creosote, you’re getting less heat and producing more smoke on the days you’re allowed to burn. A professional sweep and inspection for a Denver wood-burning fireplace runs $189-$289. We document everything with camera footage, so you know exactly what kind of creosote you’re dealing with and whether it’s a brush job or a mechanical removal.
Fireplace Insert
Many Denver homeowners install EPA-certified fireplace inserts to get more heat out of their existing masonry fireplace. The problem we see repeatedly: people run the insert at low smolder to stretch wood on green days, which drops flue gas temperature and accelerates glazed creosote formation inside the liner. A properly sized and installed insert with an insulated liner solves this. We install inserts with liners sourced from DuraFlex, Gelco, and Olympia Chimney. Insert installation in Denver typically runs $3,800-$6,500 complete, depending on the unit, liner length, and whether we need to modify the existing firebox or damper. You get a written breakdown before we order anything.
Damper Repair
Denver’s freeze-thaw cycles are brutal on dampers. When a damper sticks open, cold air drops down the flue and freezes the firebox, which accelerates spalling and mortar blowout. When it sticks closed, you risk carbon monoxide buildup. Damper repair in Denver runs $240-$480 for a standard throat damper replacement or repair, and $600-$1,200 if you’re converting to a top-sealing damper. In older Denver homes, we often find the original cast-iron damper rusted through entirely. That’s not a repair; it’s a replacement. We’ll show you the rusted part on camera before we swap it.
Trusted Brands We Service in Denver
We stock parts for common Denver fireplace brands so most repairs happen in one visit. We service and install units from Copperfield, Famco, Gelco, and Olympia Chimney, among others. If your insert or gas log set is from a brand we don’t list here, call anyway, there’s a good chance we service it. Stocking parts locally means we’re not waiting on a distributor in another state while your fireplace sits dead through a Chinook snap. That matters when the next cold front is 48 hours out.
Common Fireplace Problems We See in Denver Homes
- Oversized coal-era flues in pre-1950s homes. Houses in Congress Park, Whittier, and Baker were built with fireboxes sized for coal, not wood. The flues are larger than current best practice calls for, which slows the smoke column, cools the flue gases, and deposits creosote fast. Owners who converted to wood often assume annual cleaning is enough. It sometimes isn’t.
- Glazed third-degree creosote in low-smolder inserts. We see this constantly in Denver: an EPA insert run at low smolder on green days to stretch wood. The flue gas temperature drops, first-degree creosote glazes into second and then third degree. Mechanical removal is required. That runs roughly triple the cost of a standard sweep.
- Deferred damper repair freezing the firebox. A stuck-open damper lets cold Denver air pour down the flue all winter. The firebox freezes and thaws repeatedly, worsening spalling and mortar blowout. By the time we’re called, a $300 damper repair has become a $1,200 firebox rebuild.
- Freeze-thaw crown damage pulling in moisture. Denver crosses the freezing threshold 60 or more times per year. Every crossing is another cycle of water in the chimney crown expanding and contracting. Crown cracks open, water gets behind the brick, and the next Chinook finishes the job. We assess crown condition on every visit because in Denver it’s never a question of if, only when.

FAQs - Fireplace Services in Denver
No. The RAQC burn restrictions are not a full-season ban. Denver’s winter air-quality curtailment program restricts wood burning on designated days when temperature inversions trap particulates in the basin. On other days, designated as green days, you can burn legally. The catch: if your fireplace is inefficient and your flue is dirty, you’re getting less heat and producing more smoke on the days you can burn. A clean, well-maintained fireplace maximizes the legal burn days you do have. Call (980) 580-8641 to schedule a sweep and camera inspection before the next inversion.
Because your flue is almost certainly oversized for a wood fire. Pre-WWII Denver homes in neighborhoods like Congress Park, Baker, and Whittier were built with coal-burning fireboxes and clay tile liners sized for coal exhaust volume. When converted to wood, the fire is smaller than the flue was designed to handle. Smoke moves slowly up the liner, cools, and deposits creosote at an accelerated rate. At 5,280 feet, the effect is worse: thinner air means cooler, less complete combustion. If we find an oversized flue, the fix is usually a properly sized insulated liner. We’ll show you the camera footage before we recommend anything.
Yes, and not just for the obvious reasons. The conversion work in Denver almost always involves an existing masonry chimney that’s been through decades of freeze-thaw cycling. You need to know the condition of the flue liner, the firebox, the damper, and the crown before a gas line goes in and a sealed insert covers everything. If the liner is cracked or the mortar is failing, you’ll want that addressed during the conversion, not discovered later as a carbon monoxide or moisture issue. Inspections run as part of the install quote. Call (980) 580-8641 to schedule.
Yes. A cracked crown lets water into the chimney structure. In Denver, that water freezes and thaws 60+ times per year, expanding cracks and pushing mortar joints apart. Eventually the flue tile itself shifts or cracks, which changes the draft path and can cause smoke rollback into the room. The crown is not cosmetic. It’s the roof of the chimney. We inspect it on every visit, and we photograph any cracks so you can see the damage yourself. Crown repair or replacement in Denver typically runs $400-$1,200 depending on the crown size and whether we need to pour a new concrete crown or seal the existing one.
Annually, at minimum. If you’re burning on every green day in a pre-1950s home with an unlined or oversized flue, we recommend checking mid-season, especially if you notice sluggish draft or smoke rollback on cold mornings. Many Denver households that burn through the full green-day season accumulate second-degree creosote within a single winter, even with a fall sweep. The camera inspection we do on every visit tells you exactly where you stand. If you’re in a newer home with a properly sized insulated liner, annual service is usually sufficient. Call (980) 580-8641 to schedule, and we’ll tell you what your specific home actually needs.
