We’ve been working on Avondale chimneys since 2014. We know the 60618 ZIP code’s housing stock: the 1910s-1930s bungalows along Belmont and Diversey, the brick courtyard buildings near Kedzie, the two-flats on Pulaski and Cicero Avenue. These chimneys were built for coal, converted to gas, and now they’re showing their age. Our Chimney Liner & Rebuild team has replaced cracked terra cotta liners in hundreds of Avondale homes. We document every inspection with photos you’ll see, and we explain what’s wrong in plain English before we start any work.

If it’s sound, we’ll tell you that too. Our 90-Day Done Right Promise covers every job in writing - if it’s not right, we come back, no arguing, no paperwork games.

Our Chimney Liner & Rebuild Services in Avondale
Stainless Steel Liner Installation
Avondale’s original coal flues are oversized for modern gas appliances. That mismatch creates condensation, poor draft, and carbon monoxide risk. We install insulated stainless steel liners from DuraFlex that resize the flue to match your appliance’s output. In Avondale’s climate, with heating season running October through April, proper insulation matters. Cold exterior chimneys on these tall, narrow bungalows produce more condensation than shorter suburban stacks. Our insulated liners keep flue gases warm enough to rise, preventing the acidic condensation that destroys mortar from inside.
Flexible Liner Solutions
Some Avondale chimneys have offsets or bends that rigid pipe can’t navigate. We’ve fitted flexible liners into century-old flues that snake around structural members added during past renovations. Flexible liners also work well in two-flats where each unit needs a separate liner dropped through the same chimney stack. We size each liner to its specific appliance - furnace, water heater, or fireplace - and we document the before-and-after with our camera system.
Liner Replacement
Replacement is what we do most often in Avondale. The terra cotta liners installed during 1950s-1970s gas conversions have reached end of life. Chicago’s freeze-thaw cycles crack them. Once cracked, they channel exhaust gases into mortar joints, and from there into adjacent flues or living spaces. We remove the failed terra cotta and install a new stainless steel system, properly sized, properly insulated, with a lifetime warranty on the liner itself.
Partial Chimney Rebuild
When spalling brick and failed mortar extend beyond what repointing can fix, we rebuild. In Avondale, we see this most often on the top four to six feet of chimney - the section exposed to worst weather. Our partial rebuilds use matching brick and proper lime-based mortar compatible with your original construction. We worked on a 1920s courtyard building on Cicero Avenue where a shared chimney stack served two units. The first-floor flue had been abandoned during a gas conversion, but never capped, so rainwater and squirrel nests were rotting the adjacent flue’s mortar from inside. We cleaned both active flues, replaced the cracked terra cotta liner with insulated DuraFlex stainless steel, and installed a weather-tight cap to seal the abandoned flue permanently.

Common Chimney Liner & Rebuild Problems We See in Avondale Homes
- Cracked terra cotta from freeze-thaw damage. The undersized inserts installed during mid-century gas conversions weren’t built for Chicago’s temperature swings. Water seeps into hairline cracks, freezes, and widens them. By the time you notice draft problems, the liner is often failing in multiple locations.
- Abandoned flues left open in shared stacks. In Avondale two-flats it’s routine to find that one flue in a shared stack was quietly abandoned at the coal-to-gas conversion and never capped - leaving an open channel that funnels rainwater and nesting debris directly against the still-active adjacent flue liner, rotting the mortar from the inside out across both units.
- Downdraft from oversized coal-era flues. Original chimney heights and flue diameters were calculated for high-BTU coal combustion. Modern gas inserts produce lower draft. The result: combustion gases spill back into living spaces, especially on windy days or when appliances first cycle on.
- Spalling brick at the roofline. Avondale’s pre-WWII lime mortar is softer than modern Portland cement, which was the right choice for the era but degrades faster under decades of freeze-thaw. The top of your chimney takes the worst weather, and that’s where we most often find mortar turned to sand and brick faces popped off.
Pricing for Chimney Liner & Rebuild in Avondale, IL
Here’s what Avondale homeowners typically invest:
| Service | Typical Range in Avondale |
|---|---|
| Single-flue stainless steel liner replacement | $2,800 - $4,200 |

What moves the number: accessibility of the chimney (steep roof, narrow alley), whether we need to remove old terra cotta in pieces, and if the flue has offsets requiring flexible liner. Multi-unit buildings cost more because we’re lining multiple flues, but the per-unit price often drops compared to separate single-family jobs.

FAQs - Chimney Liner & Rebuild in Avondale
Yes, we inspect every flue in a shared stack, and in Avondale’s two-flats this often reveals problems that would otherwise go undetected. Abandoned flues funnel moisture and debris onto active liners, and cracked liners in one flue can vent exhaust into adjacent flues. Our Level-2 camera inspection documents the condition of each flue with photos you can see. Call (888) 289-6055 to schedule - estimates are free.
If the terra cotta is cracked or was undersized for your current appliance, stainless steel is the right replacement. Avondale’s freeze-thaw cycles destroy terra cotta; stainless steel expands and contracts without cracking and carries a lifetime warranty. We’ll camera-inspect your existing liner and show you exactly what we find. Call (888) 289-6055 for a free assessment.
An open, abandoned flue is a direct path for carbon monoxide, smoke, or fire to travel between units or floors, and in Avondale’s shared-stack buildings this is a documented hazard. It also channels moisture that destroys mortar in active flues. We seal abandoned flues properly with a permanent cap and verify the seal with our camera. Call (888) 289-6055 - we’ll inspect it at no charge with any service call.
Spalling brick means the masonry shell is failing, and a new liner inside a crumbling chimney won’t solve the problem. We evaluate the extent of damage: if it’s localized to the top few feet, a partial rebuild plus liner replacement is usually the right fix. If the damage extends below the roofline, full rebuild may be necessary. We’ll show you photos and explain exactly what we found. Call (888) 289-6055 for an honest assessment.
A properly installed, insulated stainless steel liner should last the lifetime of the home. In Avondale, the critical factor is proper insulation - our long heating season and cold exterior chimneys create condensation that attacks uninsulated liners from inside. We specify insulated DuraFlex systems and verify proper installation with post-install camera inspection. Done right, you should never need to replace it. Call (888) 289-6055 to discuss your specific chimney.
