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.
Fast, Reliable Chimney Inspection Across Chicago
A chimney inspection in Chicago typically runs $189 – $349 for a Level 1 or Level 2, and most inspections are scheduled within a few days rather than a few weeks. That’s the direct answer. But the real reason to care about which company you call has everything to do with what Chicago chimneys actually are: roughly 80,000 brick bungalows from the coal-burning era, most with clay-tile flues that were never designed for the gas appliances now venting into them. We inspect those conditions every week, from Portage Park to Bridgeport. Call (336) 863-3889 and we’ll give you a straight answer about your chimney before we ever set foot inside.
Why Alcott Chimney Sweep Is Chicago’s Preferred Chimney Inspection Company
Our Chimney Inspection team works with one rule that matters more than any sales pitch: we don’t recommend a repair unless we can show you the problem on camera. In a city where two-flats and three-flats share single masonry chases, and where under-fired gas flues quietly crack clay-tile liners, that’s not a slogan. It’s the only way a homeowner can know the difference between a real failure and a scare-sell.
Ruben Castellano set that standard in 2002 when he founded Alcott Chicago Chimney Sweep as part of the Threshold Group family of home-service companies. Every technician who comes to your door in Chicago passes a background check and identity verification before they ever get your address. 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 single time.
Chicago homeowners don’t have to take our word for any of this, because we put a written price in your hand before any work begins, and every repair comes with a written guarantee. If the repair fails during the coverage period, the second visit is free. That’s the 365-Day Done Right Promise, and it applies to inspection findings, liner resurfacing, crown repairs, and anything else we touch.
Chimney Inspection Services in Chicago
Chimney Inspection Services in Chicago are built around the reality of our housing stock: original clay-tile flues, shared chases in two-flats and three-flats, and decades of lake-driven freeze-thaw working on the mortar. A standard Level 1 inspection runs $189 – $229 and covers what you can see and what our tech can reach without tools. A Level 2 inspection with a camera runs $299 – $349 and is what we recommend whenever a Chicago home is changing ownership, changing fuel type, or showing draft symptoms.
Level 1, Level 2, and Level 3 inspections, explained
A Level 1 is the right call when nothing has changed: same appliances, same fuel, same usage, and no known problems. A Level 2 adds the camera and is what really matters in Chicago, because the damage we typically find is invisible from the roof. A Level 3 inspection involves opening a section of the chimney structure and is only recommended when a Level 2 has already documented a failure that needs direct access to confirm. We won’t push a Level 3 unless the camera evidence justifies it.

Real estate inspections for Chicago sales
Buying or selling a bungalow in Avondale or a two-flat in Bridgeport? You need a Level 2 camera inspection before closing. Conventional home inspectors look at a chimney from outside and won’t catch the interior liner damage that shows up on video. We document everything and give you and the seller a written report you can actually act on.

Chimney Flue Inspection in Chicago
Chimney Flue Inspection in Chicago is where our camera work separates real problems from overpriced guesswork. The flue is the interior passage that carries combustion gas up and out, and in Chicago’s older homes it’s usually clay tile that was sized for coal, not natural gas. Those oversized flues run too cool on gas appliances, which means acidic condensate sits against the tile and eats it from the inside. Camera inspection shows this clearly.
What the camera sees that the rooftop check misses
From the roof, a bungalow chimney in Portage Park might look fine. Inside, cracked tile joints, spalled mortar, or a hollow outer brick wall behind an old insert liner can be hiding. We ran a camera down a two-flat on the 3300 block of North Keating where the downstairs tenant reported a sulfur smell. The original clay-tile flue was cracked along two tile courses above the smoke chamber, and the outer brick around the 1950s insert liner had gone hollow from decades of freeze-thaw. We documented it on video, explained it in plain English, and rebuilt the flue with a HeatShield-resurfaced liner before heating season.
Condensate damage and backdraft in gas-era chimneys
When gas appliances vent into an oversized coal-era flue, the exhaust doesn’t stay hot enough to rise efficiently. That means backdraft, which pushes combustion gases back into the home instead of up the chimney. In a shared two-flat or three-flat chase, one compromised flue can backdraft into every unit at once. This isn’t a rare problem in Chicago. It’s the condition we expect to find on a meaningful share of pre-1940 housing stock.
Trusted Brands We Service in Chicago
When repairs are needed, we carry and install the same professional trade materials chimney professionals specify, not the box-store substitutes that weather a single Chicago winter before failing again. That means HeatShield resurfacing for liners damaged by acidic condensate, Gelco and Olympia Chimney caps and chase covers built for lake-driven wind and moisture, and Famco components for proper draft and termination. We keep common Chicago bungalow and two-flat parts stocked for fast turnaround, and every material install carries our written repair guarantee.
Common Chimney Inspection Problems We See in Chicago Homes
- Cracked clay-tile flue liners from under-fired gas conversions. Chicago bungalows built 1910 – 1940 for coal heat have flues massively oversized for today’s gas appliances. The exhaust runs too cool, acidic condensate forms, and the tile cracks from the inside, a failure you can’t see from the roof.
- Hollowed-out outer brick behind old insert liners. When furnaces switched from coal to gas, many bungalow-belt homes got a smaller insert liner while the original brick chase stayed in place. Decades of Lake Michigan freeze-thaw have spalled the brick behind that liner, and only camera inspection finds it.
- Shared masonry chases in two-flats and three-flats. One chimney stack, multiple flues, multiple units. A failed crown or spalled mortar lets moisture in and puts every unit’s heating at risk simultaneously. This is a Chicago multi-family fact of life that standalone suburban homes don’t face.
- Backdraft and first-degree creosote buildup between annual inspections. Under-fired oversized flues don’t establish proper draft, which pushes combustion gas back into living spaces. It happens quietly, often between routine sweeps, and carbon monoxide risk goes up accordingly. This is why we push annual camera-grade checks on older Chicago homes, not as a sales tactic but as a safety baseline.

FAQs About Chimney Inspection in Chicago
Yes. A Level 2 camera inspection sees the full length of the flue without opening the chimney structure at all. The camera goes up or down the flue and shows us on video whether the tile is intact, whether mortar joints are cracked, and whether the outer brick chase is still solid behind it. Call (336) 863-3889 for a Level 2 price and a straight answer about what your flue actually looks like from the inside.
That smell is often sulfur from combustion gases being pulled back into the basement instead of rising through the flue, and in Chicago’s shared two-flat chases it’s a known failure pattern after freeze-thaw cycles open hairline cracks in the crown and upper flue. The NW wind off Lake Michigan pushes moisture into those cracks and the cold snap stresses the chase further. A camera inspection will show whether backdraft is coming from your flue or from a neighboring unit’s flue inside the same masonry chase. Book an inspection at (336) 863-3889 and we’ll document it for you.
For most Chicago homes, yes, annual inspection matters even on gas-only appliances. The under-fired oversized flues in our older housing stock create backdraft and condensate problems that have nothing to do with wood burning, and they develop on their own schedule. One year without a camera look can be enough for a hairline crack to turn into a carbon monoxide pathway. An annual Level 2 in Chicago is cheap insurance against a failure mode specific to this city’s housing stock. Call (336) 863-3889 to schedule.
A Level 1 is a visual check of accessible areas and runs $189 – $229. A Level 2 adds a camera and is what we recommend for real estate transactions, fuel-type changes, or any Chicago home showing draft symptoms, and runs $299 – $349. A Level 3 opens part of the chimney structure and is only done when a camera has already documented damage that needs direct access to confirm. We won’t upsell you to a Level 3 on a guess. Call (336) 863-3889 if you’re unsure which one applies to your situation.
A standard sweep is a cleaning, not an inspection. The sweep removes creosote and soot but doesn’t put a camera down the flue, and the cracked clay tile and hollowed brick we find in Chicago’s bungalow-belt chimneys is invisible from the top of the flue and from the firebox. A camera documents what a brush cannot see. That’s the difference between a sweep and a Level 2 inspection, and it’s exactly why we recommend the camera on older Chicago chimneys even after a recent cleaning. For a second opinion with video evidence, call (336) 863-3889.
