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.

AfterFast, Reliable Chimney Sweep Across Chicago
A chimney sweep in Chicago typically costs between $189 and $329 for a standard single-flue cleaning with a Level 1 inspection, and most jobs are completed in under two hours. We serve every neighborhood in the city, from Rogers Park down to Hegewisch, with technicians who know the difference between a Wicker Park greystone and a Mount Greenwood brick ranch before they even ring the bell. Chicago’s housing stock is its own animal, and a chimney that survived 100 winters here deserves a sweep who understands what those winters do to masonry. Call (336) 863-3889 to book, and you’ll know exactly who’s coming to your door before the truck leaves our Chicago office.
Why Alcott Chimney Sweep Is Chicago’s Preferred Chimney Sweep Company
We’ve been sweeping Chicago chimneys long enough to know that no two are alike, even on the same block. A two-flat in Avondale built in 1912 and a bungalow in Beverly built in 1928 both might have clay-tile flues, but they’ve aged differently depending on how the wind hits them, what the furnace conversion looked like, and whether anyone ever re-crowned the masonry after the liner was swapped. Our Chimney Sweep team works on all of them daily.
Chicago homeowners tell us the same two things after every job. First, they appreciate that the written price they approved is the exact price they paid. Second, they remember the technician’s name and face because we sent both before the visit, and the tech showed a photo ID badge at the door, no exceptions. That’s the Threshold Standard, and it’s not an add-on you have to request.
Ruben Castellano built Alcott Chimney Sweep on a simple idea: a homeowner should never have to gamble on whether the person at the door is the person they were told to expect. Every technician is background-checked, identity-verified, uniformed, and announced by name and photo ahead of time. You’ll see a face before you hear a knock.
Gas Fireplace Cleaning in Chicago
Gas Fireplace Cleaning in Chicago is about more than shaking dust off ceramic logs; it’s about verifying that the unit vents correctly into a flue that may have been serving this city’s homes since before anyone alive today was born. If your unit needs more than a cleaning, our Gas Fireplace Repair - Chicago team handles venting issues, damper problems, and component replacements. A gas fireplace produces less creosote than wood, but it can still push carbon monoxide into a living room if the flue is partially blocked, the damper is malfunctioning, or the chimney chase has a hidden crack. In Chicago, where so many gas inserts were retrofitted into masonry fireplaces originally built for coal or cordwood, that venting path deserves a close look every single year.
The venting check nobody taught you
We trace the full exhaust path from the unit itself, through the connector pipe, and up the flue. On gas inserts in Chicago’s older buildings, we regularly find the original clay-tile flue was never sized down when the gas insert went in. That oversized flue cools the exhaust too quickly, condensing acidic moisture onto the tile. You won’t see it from the hearth, but our camera will.
What it costs
A gas fireplace cleaning and vent check in Chicago runs $149 to $229. If the flue hasn’t been swept in years and creosote from prior wood burning is still glazing the tile, we’ll quote the added sweep before we start. You approve the written price first, always.
Chimney Maintenance in Chicago
Chimney Maintenance in Chicago is less about “once a year, whatever happens” and more about catching what Lake Michigan’s weather does to masonry between visits. The freeze-thaw cycle here is relentless: Chicago regularly swings 30 to 40 degrees in a single late-winter day, and every swing forces water deeper into hairline crown cracks, then freezes it, expanding those cracks a little further. A crown that looked fine in October can be spalling by March. Annual maintenance keeps small problems small.
What a maintenance visit covers
We inspect the crown, the flashing where the chimney meets the roof, the mortar joints on the visible exterior, and the flue interior below. We sweep as needed, note any shifting or staining, and document everything with photos. You get a written summary of what we saw, what it means, and what can wait versus what can’t.
The camera is standard
Every maintenance visit in Chicago includes a camera inspection of the flue interior. That’s not an upgrade. It’s how we catch what a brush alone can’t: a cracked tile, a failed mortar joint mid-chase, or a void behind an insert liner that a visual-only sweep would miss entirely. If it’s on the camera, we show it to you on screen, not just describe it in a report.
Trusted Brands We Service in Chicago
We install and service the same materials Chicago’s commercial chimney contractors specify, and we keep them stocked for the city’s specific building types. That means DuraFlex liner systems sized for the oversized coal-era flues still standing in tens of thousands of Chicago bungalows, HeatShield resurfacing for clay-tile liners with surface degradation but sound structure, and components from Olympia Chimney and Famco for gas fireplace venting and caps. When a two-flat in Lincoln Square needs a repair, we’re not waiting a week for parts from a warehouse in another state. We carry what Chicago’s chimneys actually need.
Common Chimney Sweep Problems We See in Chicago Homes
- Hollowed-out brick chases behind insert liners. When a bungalow’s furnace was converted to gas decades ago, a smaller metal liner was often dropped into the original chimney, but the surrounding brick chase was left untouched. Freeze-thaw has been quietly hollowing out that outer structure ever since, and the only way to see it is a camera pointed behind the liner.
- Shared flue issues in two-flats and three-flats. Chicago’s multi-unit buildings frequently run multiple flues through a single masonry chase. One cracked crown or a failed liner on one flue can push exhaust back into every unit that shares the same structure, and a sweep who only runs a brush up one flue will miss it.
- Third-degree creosote glazed onto clay tile. The tar-like, glassy creosote that forms when a chimney runs cool is stubborn, and a wire brush barely touches it. In Chicago, where oversized flues promote condensation, we see third-degree glaze more often than in surrounding suburbs. Chemical treatment or removal may be required before a standard sweep is effective.
- Spalling mortar joints along the upper courses. The persistent northwest wind off Lake Michigan, the one old-timers call the Hawk, drives rain into hairline cracks and accelerates mortar failure. On exposed chimneys in neighborhoods like Portage Park or Jefferson Park, we routinely find joint deterioration that would have been minor if caught the year before.
Pricing for Chimney Sweep in Chicago, IL
Here’s the honest range, because you should know before you call. A standard chimney sweep in Chicago runs $189 to $329, depending on flue height, the degree of creosote buildup, and whether an insert liner complicates access. A Level 1 inspection is included with every sweep at no added cost. A standalone Level 2 inspection, which uses the full camera setup and is required for real estate transactions or after a chimney fire, runs $349 to $599 in Chicago. Creosote removal for heavy third-degree glaze adds $75 to $185 if chemical treatment is necessary. You’ll get a written price before any work starts, and the price we quote is the price you pay. Call (336) 863-3889 for a free estimate, and we’ll give you real numbers, not a sales pitch.

FAQs About Chimney Sweep in Chicago
Nearly always, yes. Chicago’s roughly 80,000 bungalows were built between 1910 and 1940 with chimneys sized for coal-burning furnaces, and when those furnaces were converted to natural gas, the oversized clay-tile flues were left in place. Gas exhaust runs much cooler than coal exhaust, so it condenses inside the flue, creating acidic moisture that eats the clay tile from the inside. A properly sized stainless liner from a brand like DuraFlex corrects the problem, but the only way to know for sure is a camera inspection. Call (336) 863-3889 and we’ll show you exactly what your flue looks like, not just tell you it needs work.
Every year, and ideally before October. The freeze-thaw cycles driven by Lake Michigan are more aggressive in Chicago than in most inland Midwest cities at the same latitude, because the temperature swings are both rapid and severe. A chimney that went through last winter without an inspection may have developed crown cracks or spalling that hadn’t started yet in the fall. We recommend a sweep and Level 1 inspection every fall for chimneys in regular use, and a camera inspection every two to three years to catch what the brush can’t. The cost of a sweep is a fraction of what a failed liner or a collapsed crown costs to fix.
Yes, and this is one of the most common safety problems we find in Chicago’s two-flat and three-flat buildings. Multiple flues running through a single masonry chase means that a cracked crown on top, or a deteriorated liner in one flue, can create backdraft conditions that push exhaust into every unit connected to that chase. We’ve inspected buildings where the owner lived in one unit and a tenant in the other, and neither knew that the shared chase was the source of a heating-season headache. A full-chase camera inspection is the only way to see the condition of both flues, not just the one attached to the unit that called us.
Third-degree creosote is the glassy, tar-like glaze that forms when a chimney runs consistently cool, which Chicago’s oversized flues and damp lake air both encourage. It’s hardened and fused to the flue surface, so a standard wire brush skates right over it. Leaving it in place is a genuine fire hazard, because that glaze ignites more readily than powdery first-degree creosote. Removing it requires chemical treatment, a rotary cleaning head, or both, and it should be done by a trained chimney professional, not as a weekend DIY project. We’ll show you the glaze on camera before we treat it, so you’re never paying for a removal you have to take on faith.
We won’t recommend any work we can’t show you on camera, and we’ll tell you plainly when a rebuild is necessary and when a less invasive repair will do the job. In a Portage Park bungalow on North Lockwood, a homeowner called us after a gas furnace kept tripping the draft hood. Our tech put a camera up the flue and found the insert liner was intact, but the surrounding original brick chase had been hollowed out by decades of freeze-thaw. One company had quoted a full teardown and rebuild. We documented the void on camera, showed the homeowner what we saw, and recommended a HeatShield liner repair instead. That’s the standard we hold ourselves to on every Chicago job.
