Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.
Chimney Company in Avondale, IL
Chimney repair in Avondale usually starts with a masonry or liner problem, not a dirty flue. The neighborhood’s dense rows of brick two- and three-flats built between the 1890s and 1920s share chimney stacks between units, which means a crack in one flue can affect every apartment in the building. Sandstone Chimney Sweep has served Avondale since 2017, and on most jobs we’re looking at freeze-thaw damage to crowns and mortar joints, rusted dampers from humid summers, and original clay tile liners that have outlived their useful life. Call (833) 589-7835 when you need a straight answer about what your chimney actually needs.
Why Avondale Homes Are Different
Avondale’s housing stock was built for coal heat and gas conversion, not for modern furnace exhaust. The typical Chicago-style brick two- or three-flat has a chimney stack running up through the center of the building, serving furnaces and water heaters for multiple units. Those flues were often built with clay tile liners, or in some cases no liner at all, and they’ve been doing the same job for over a century. When we sweep or inspect a chimney in Avondale, we’re rarely just brushing out creosote. We’re checking whether each unit’s flue is properly separated from its neighbors, whether the clay tiles are still intact after decades of thermal cycling, and whether the mortar joints between tiles have started to fail.
The climate does steady damage here. Avondale’s cold, windy winters push freeze-thaw cycles into every crown and mortar joint on exposed brick. Water gets in, freezes, expands, and spalls the face off brick and mortar alike. Then the humid summers come and work on the metal components, rusting dampers and encouraging efflorescence on interior masonry. A chimney that looked serviceable in May can have open joints by February. That’s why we pair cleaning with crown and flashing repair so often in this part of the city.
Landlord compliance is a real factor too, because so many Avondale buildings are rental properties. Owners need documentation that each unit’s flue is separated, lined, and safe before heating season. We provide that paperwork as part of the inspection, and we can walk you through what city inspectors typically look for in a multi-unit chimney system.
Styles & brands we work with
Our Main Avondale Services
Most Avondale homeowners call us for one of two reasons: they need their fireplace or furnace flue swept before burning season, or they need their dryer vent cleared because the airflow has dropped and the dryer is running hot. Both are fire hazards, and both can be handled in a single visit.
Chimney Sweep in Avondale
A chimney sweep in Avondale isn’t the quick brush job it might be in a newer suburb. With original clay tile flues shared between units, sweeping here frequently involves running a camera first to confirm the liner is actually intact before we put any mechanical brushes to work. Soot and creosote hide what’s behind them, and on these old party-wall stacks, what’s behind them is often cracked tile or missing mortar. We also check the chimney cap, crown, and flashing while we’re on the roof, because Avondale’s weather works on those from the outside. For the full details on sweeping, see our Chimney Sweep in Avondale page.
Dryer Vent Cleaning in Avondale
Dryer vents in Avondale’s older buildings often run long horizontal distances through walls and ceilings before they reach the exterior, and every foot of that run collects lint. Worse, many of these buildings have vents that exit through the roof, which homeowners don’t see and often don’t think about until the dryer starts taking two cycles to finish a load. A clogged dryer vent is one of the most common residential fire risks, and it’s one we can address the same day we’re already at the house for chimney work. See Dryer Vent Cleaning in Avondale for specifics.

Chimney Repair in Avondale
Chimney repair in Avondale is usually about the liner and the crown. Houses here date from the 1890s through the 1920s, and most still have their original clay tile liners running through shared party-wall stacks. Decades of Chicago freeze-thaw cycles have cracked tiles and opened mortar joints, and when a liner fails in a multi-unit building, the fix has to be documented and done right, not patched. Sandstone Chimney Sweep handles the full scope, from cap and flashing replacement to full liner installation, with the same team that found the problem doing the repair. That’s the difference between a sweep who hands you a report and a company that actually fixes what’s wrong. Read more about our approach on the Chimney Repair page.
Chimney Liner Installation
Signs you need it
If your sweep finds cracked clay tiles, missing mortar between tile sections, or soot leaking into the wall cavity between units, the liner has failed and needs replacement.
What it costs in Avondale
Count on $2,300 – $4,800 depending on the liner material, the height of the stack, and whether the old clay tile has to be removed first.
How we do it
We measure the flue, select a correctly sized DuraFlex liner system, run it down the existing chase, insulate as needed, and reconnect the furnace or water heater venting with a proper top plate and rain cap.
Chimney Crown Repair
Signs you need it
Hairline or open cracks in the concrete crown, spalled brick at the top of the stack, or water staining on the ceiling near the chimney all point to crown failure.
What it costs in Avondale
Expect $550 – $1,250 depending on whether we’re sealing surface cracks or rebuilding the crown entirely with a proper overhang and drip edge.
How we do it
We remove the deteriorated concrete, build forms that allow a 2-inch overhang so water sheds away from the brick, and pour a new crown with a flexible bond-break membrane underneath so it won’t crack with the next freeze-thaw cycle.
Chimney Flashing Repair
Signs you need it
Water stains on ceilings or walls near the chimney, damp attic insulation, or visible gaps where the flashing meets the brick are all signs the flashing has pulled away.
What it costs in Avondale
Plan on $450 – $950 to replace standard step flashing around a single-flue residential chimney, more if the roofline is steep or the old flashing is embedded in failed mortar.
How we do it
We cut a reglet into the brick, install new step and counter flashing with proper overlap, and seal every transition so water runs off the roof instead of into the chase.
Chimney Cap Installation
Signs you need it
If you hear birds or animals in the flue, find debris falling into the firebox, or see rain water pooled at the base of the chimney, a missing or damaged cap is likely the cause.
What it costs in Avondale
Budget $275 – $550 for a standard stainless or copper cap sized to your flue and installed with proper mechanical fasteners.
How we do it
We measure the flue opening, select a cap with mesh sized to keep animals out while letting exhaust flow, and anchor it to the crown so it stays put through Chicago wind.
What Chimney Repair Costs in Avondale
| Item | Typical range in Avondale |
|---|---|
| Chimney cap installation or replacement | $275 – $550 |

| Chimney flashing repair | $450 – $950 |

Can you repair a shared chimney flue without shutting down the whole building?
Usually, yes. We repair one flue at a time while the other units’ flues keep venting. The furnace or water heater on the flue we’re working on gets shut off for the day, and we coordinate timing with tenants so nobody is without heat or hot water longer than a few hours.
How long does a liner installation take in an Avondale two-flat?
Most liner installations in two- and three-flats take one full day, occasionally two if the old tile liner has to be broken out and removed first. We’ll confirm the timeline after the camera inspection, before any work is scheduled.
Brands We Service in Avondale
We stock and install specification-grade components from DuraFlex, HeatShield, and Famco. No big-box substitutes. That means liner systems sized to your actual flue, not a universal kit, and repair materials formulated for chimney conditions, not general masonry work. See our brands for the full line we carry, with most common parts available same week for Avondale jobs.

FAQs About Chimney Company in Avondale
For most chimney sweeps, cap replacements, and liner installations, no city permit is required because the work happens inside the existing flue or on top of the existing chimney. Major structural rebuilds above the roofline can trigger a permit, and we’ll tell you if your job falls into that category before anything starts.
Book two to three weeks ahead of when you want to start burning, which for most Avondale homes is early October. Fall fills up fast, and scheduling in September means you’re not waiting for an open slot during the first cold snap. We do keep some weekday availability for urgent jobs like water intrusion.
Yes. We inspect each flue separately, camera every liner, and note the condition of the crown, cap, and flashing. You’ll get a written report for each unit’s flue with photos and a clear recommendation, which most Avondale landlords use as their winter-readiness documentation.
