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.

AfterChimney Company in Chicago, IL
Alcott Chimney Sweep handles the chimney problems that Chicago’s housing stock is uniquely prone to: coal-era clay tile liners failing from acidic condensate, freeze-thaw spalling on crowns and mortar joints, and multi-unit flues sharing a single masonry chase. If you own a brick bungalow, two-flat, or three-flat built before 1940, your chimney was designed for solid fuel it no longer burns, and that mismatch creates problems no suburb sees at this scale. Call (336) 863-3889 and you’ll speak with a live person who can schedule the exact service you need.
Why Chicago Homes Are Different
Roughly 80,000 Chicago bungalows built between 1910 and 1940 ring the city in a distinct bungalow belt through the north, west, and south sides. Those chimneys were sized for coal-burning furnaces, then converted to natural gas by mid-century. The oversized clay-tile flues now run chronically under-fired, which lets acidic condensate sit against the liner and eat it from the inside out. That same under-firing creates backdraft conditions that push carbon monoxide into living spaces. No neighboring suburb has this density and uniformity of coal-era chimney stock paired with gas appliances.
Lake Michigan makes it worse. Chicago regularly swings 30 to 40 degrees within a single late-winter day, and those rapid freeze-thaw cycles spall mortar joints and chimney crowns faster than inland Midwest cities at comparable latitudes. The persistent northwest wind off the lake, the one locals call the Hawk, drives moisture into hairline crown cracks and forces it deeper with every cycle. By October, when heating season starts, a crown that looked fine in June can be shedding brick fragments into the flue.
Two-flats and three-flats add another layer. They frequently share a single masonry chase with multiple flues, so one deteriorating crown or failed liner can compromise heating for every unit at once. That’s a building-wide problem, not a single-unit one, and it usually surfaces as a smell complaint in the top-floor unit before anyone sees the cause.
Our Main Chicago Services
Chicago homeowners call us most often for two jobs: a thorough sweep before burning season and a camera inspection when something doesn’t smell right. Here’s what each involves in this city.
Chimney Sweep in Chicago
A Chicago sweep starts with understanding what’s actually in the flue. In bungalow-belt homes converted from coal, that’s often a combination of creosote from occasional wood fires and acidic residue from the gas furnace venting through an oversized clay liner. We remove the buildup, check the crown and cap from the roof, and tell you plainly whether the liner needs attention or can safely wait. In neighborhoods like Portage Park and Avondale, we frequently find the original brick chase hollowed out behind a smaller insert liner, a condition only visible with camera work. Full details are on the Chimney Sweep in Chicago page.
Chimney Inspection in Chicago
Given the freeze-thaw stress Chicago chimneys absorb, our inspections include a camera run every time. That’s the only way to see what’s happening behind the liner or inside a shared multi-flue chase. We look for spalled mortar, hidden crown cracks, and the specific failure mode this city is known for: an intact inner liner with an outer brick structure crumbling behind it. What we find gets documented with photos you can see and keep. You’ll know exactly what needs work now, what can wait, and why. See the Chimney Inspection in Chicago page for what a Level 1 and Level 2 inspection each cover.
Gas Fireplace Repair in Chicago
Gas fireplaces vent through the same freeze-thaw-exposed chases as wood-burning fireplaces, and Chicago’s temperature swings take a toll on venting components. When a pilot won’t stay lit, a burner runs unevenly, or the unit shuts down mid-cycle, the cause is often a blocked or deteriorated vent rather than a bad valve. We diagnose the full vent path, not just the firebox, and we repair with professional-grade parts including DuraFlex, Olympia Chimney, and Famco components. The Gas Fireplace Repair in Chicago page explains what we service and what we stock.

Brands We Service in Chicago
We install and service HeatShield resurfacing systems, Gelco caps and chase covers, Olympia Chimney venting, and Famco components. When a repair calls for a specific part, we’re not substituting whatever the big-box store had on the shelf. You can see the full range on our brands page, but the short version is this: we specify the same materials a chimney professional would, and we explain what each one does before it goes into your chimney.
Pricing for Chimney Company in Chicago, IL
Every job starts with a written price before any work begins, so the numbers below are what you can expect in this market, not a teaser rate.
| Service | Typical range in Chicago |
|---|---|
| Standard chimney sweep | $180 – $340 |
| Chimney inspection (Level 1) | $150 – $275 |
| Chimney inspection (Level 2, camera) | $300 – $550 |
| Gas fireplace repair (diagnostic + minor parts) | $200 – $475 |
| Gas fireplace repair (major component replacement) | $400 – $1,200 |

| Flue relining (stainless or HeatShield) | $3,200 – $7,500 |
| Chimney cap supply and install | $225 – $650 |
What pushes a Chicago job past the baseline is predictable: a three-story two-flat takes longer to set up on than a single-story bungalow, and a flue that’s been absorbing freeze-thaw damage for decades often reveals more than one issue once the camera goes in. Whatever we find, you get a written price before work starts, and a written guarantee on every repair. If the repair fails within the coverage period, the second visit is free.

FAQs About Chimney Company in Chicago
Most sweeps and inspections in Chicago are scheduled within a few days. When you call, a live person answers, confirms what you need, and gives you a booking window that accounts for your neighborhood and the current schedule. We’ll send the technician’s name and photo before we arrive, and that technician will show a photo ID badge at your door.
Routine sweeping and Level 1 or Level 2 inspections don’t require a permit. Structural repairs like rebuilding a crown or relining a flue may, depending on scope and whether the building is a single-family home or a multi-unit. We’ll tell you plainly whether your job falls into the permit category before any work is booked, so there are no surprises.
You’ll already know the technician’s name and what they look like, because we send both before the truck leaves. The technician arrives in uniform, shows a photo ID badge, and covers the work area before starting. You’ll get a written price before any work begins, and a full explanation of what was found and what it means after the job is done.
