Fast, Reliable Chimney Liner & Rebuild Across Northlake
Chimney liner repair and rebuild in Northlake typically runs $1,800-$6,500 depending on whether you need a stainless steel reline or partial masonry reconstruction, and most jobs are completed in a single visit. If your Northlake home still has its original clay flue from the 1950s or 1960s oil-burning days, you’re likely venting a modern gas furnace through an oversized chimney that collects acidic condensation and destroys mortar from the inside out. We’ve been driving to Northlake since 2014, and our crew knows the postwar brick bungalows along Grand Avenue, the ranches near Roy Park, and the shared flue configurations that show up on almost every block.

Our Chimney Liner & Rebuild Services in Northlake
Stainless Steel Liner Installation
A stainless steel liner is the permanent fix for most Northlake chimneys. We install 316Ti alloy DuraFlex liners sized precisely to your gas furnace or boiler output, not the original 8×13-inch clay flue designed for coal or oil. On a 1958 brick bungalow on Hillside Avenue, we found a shared flue for a gas furnace and water heater, both undersized for the 8×13-inch clay liner. Acidic condensation had eaten the mortar jointing below the roofline. We installed a 6-inch DuraFlex stainless steel liner with a top plate and sealed the excess flue area, restoring draft and eliminating the carbon monoxide risk. The job took six hours. Most Northlake stainless steel relines run $2,200-$3,800.
Flexible Liner Solutions
Not every Northlake chimney is straight. The offset flues in some 1960s ranches near Wolf Road need a liner that bends without cracking. Flexible DuraFlex liners handle offsets up to 45 degrees while maintaining the smooth interior that resists creosote buildup. We pull these through from the top, seal the connection at the appliance, and pressure-test before we leave. Flexible liner installation in Northlake typically costs $2,400-$4,200 depending on length and offset complexity.
Liner Replacement
When a clay liner has separated, shifted, or collapsed, spot repair won’t hold. We extract the damaged sections and install a new stainless steel liner that carries the full appliance load. In Northlake’s freeze-thaw zone, we see liner replacement as preventive medicine. A cracked liner left through winter lets water penetrate the surrounding brick, and by spring you’re looking at spalled courses and a partial rebuild. Liner replacement in Northlake runs $1,800-$3,500 for standard furnace flues.
Partial Chimney Rebuild
Sometimes the liner is sound but the masonry around it is not. Northlake’s 70-year-old lime mortar crumbles under repeated freeze-thaw cycling, especially on south-facing chimneys that warm in sun then refreeze overnight. We rebuild from the roofline up, replacing spalled brick, repointing joints with matching mortar, and installing a proper concrete crown with drip edge. Partial rebuilds in Northlake typically range $3,500-$6,500. We complete most in one day, weather permitting.

Common Chimney Liner & Rebuild Problems We See in Northlake Homes
- Oversized flues from oil-to-gas conversions cause slow, incomplete venting that accelerates acidic condensation and mortar deterioration. Nearly every Northlake home built in the 1950s-1960s converted from oil or coal to natural gas, leaving chimneys oversized and unlined. A fuel-switch legacy that causes acidic condensation and liner failure far faster than in newer suburbs.
- 70-year-old lime mortar joints crumble under freeze-thaw cycles, leading to cracked liners and spalled bricks before a full rebuild is needed. Northlake sits in the Chicago metro’s full continental freeze-thaw zone, with repeated cycles of subfreezing temps and thaws each winter that drive water into cracked mortar and spall brick crowns and corbels.
- Shared furnace/water-heater flues create venting conflicts and backdrafting that carbon monoxide detectors may not catch early. Technicians working Northlake regularly find chimneys shared between a gas furnace flue and a gas water heater flue, a common 1960s installation practice, where neither appliance vents efficiently due to flue-size mismatch.
- Heavy seasonal use from October through March loads chimneys with creosote and soot that mask underlying liner damage. By late winter, the combination of combustion byproducts and acidic condensation has often done more harm than a standard sweep can address without a liner assessment.

What moves the number? Height, accessibility, whether we need scaffolding on a two-story Northlake bungalow, and the condition of the existing clay. A chimney with a collapsed liner and saturated surrounding brick costs more than one with intact mortar and a simple size mismatch.

FAQs - Chimney Liner & Rebuild in Northlake
Yes. The original clay flue in your Northlake home was sized for oil or coal combustion at much higher temperatures and larger flue-gas volumes. Your modern gas furnace runs cooler and produces less draft, so the oversized flue allows exhaust to cool too quickly. That cooling creates acidic condensation that eats mortar and cracks clay from the inside. We’ve replaced liners in Northlake homes where the clay looked fine from the fireplace but was shattered above the roofline. Call (888) 289-6055 for a free camera inspection and exact quote.
That’s acidic condensate, and it means your flue is too large for your gas appliance. In Northlake, we see this almost weekly on 1950s and 1960s chimneys that were never properly resized after fuel conversion. The black liquid is corrosive enough to stain siding and deteriorate brick. A properly sized stainless steel liner eliminates the condensation by maintaining exhaust temperature all the way to the termination. Call us to measure your flue and appliance output.
Yes, and in Northlake this is one of our most common jobs. The 1960s practice of venting both appliances into one oversized clay flue creates draft conflicts and backdrafting risk. We typically install separate flexible liners or a properly sized single liner with a wye connection, depending on appliance BTU output and clearances. Both appliances then vent efficiently without competing for draft. Most shared-flue relines in Northlake run $2,800-$4,500.
Not necessarily. Cracked clay liner is a liner problem, not automatically a masonry problem. If the surrounding brick and mortar are sound, we extract the damaged clay and install a stainless steel liner that carries the load. We assess this with our camera during the Level-2 inspection. If the brick is spalled or the mortar is powdering, we’ll tell you and price both options. Most 1962 Northlake ranches we see need relining, not rebuilding. Call for a free inspection.
The musty smell usually means water is getting into the chimney system through a cracked crown, failed flashing, or deteriorated mortar, and the liner may be contributing. An oversized or cracked liner allows cool, moist exhaust to condense on the chimney walls, adding moisture to whatever rain is already entering. In Northlake’s flat terrain west of Chicago, high winds drive rain into poorly capped flues. We fix the water entry with crown repair or rebuilding, then eliminate the condensation source with proper liner sizing. The combination stops the smell and protects the masonry.
