Fast, Reliable Chimney Liner & Rebuild Across Logan Square
We got a call last Tuesday from a landlord near Logan Boulevard. Tenant on the second floor smelled soot every time the first-floor unit ran heat. That’s the Logan Square pattern we see weekly: one flue fails, but the problem shows up two floors away. Our Chimney Liner & Rebuild team was there in under an hour, camera-inspected all three flues in the shared stack, and found the collapsed clay liner that was pressurizing the whole system. Done by Thursday. Call (888) 289-6055 and a live person answers, any hour.
We’ve worked on chimneys along Kedzie, Milwaukee, and Diversey for over 42 years. Logan Square’s greystones and brick two-flats aren’t mysteries to us. They’re the buildings we grew up around. We know the original coal flues, the lime mortar that crumbles after a hard winter, and the way a 1910 chimney stack behaves when you bolt a 96% efficient furnace onto it. That knowledge saves you money and keeps your tenants safe.

Our Chimney Liner & Rebuild Services in Logan Square
Stainless Steel Liner Installation
Logan Square’s oversized coal flues were never meant for modern gas appliances. A 6-inch stainless steel liner from DuraFlex drops your flue to the correct diameter, establishes proper draft, and stops the glazed creosote buildup we see constantly in pre-1925 greystones. We size, we fit, we seal. Done right, and we stand behind it.

Flexible Liner Solutions
Some Logan Square chimney stacks have offsets or bends that rigid pipe can’t navigate. Our flexible liners from Olympia Chimney thread through century-old masonry without damaging surrounding flues in a shared stack. Critical in multi-unit buildings where you can’t afford to disturb the neighbor’s venting.

Liner Replacement & Repair
Clay tile liners crack. They collapse. In Logan Square’s two-flats and three-flats, we’ve found original liners so deteriorated that combustion gases were migrating between units. We camera-inspect every flue in the stack, not just the one you called about. Then we replace or repair with HeatShield cerfractory sealant where appropriate, or full stainless replacement where the damage is too extensive. You’ll know exactly what we found and exactly what we recommend.

Partial & Full Chimney Rebuild
When 25-35 annual freeze-thaw cycles have spalled the bricks and opened the mortar joints past saving, we rebuild. Partial rebuilds address the crown and upper courses. Full rebuilds tackle stacks where the structural integrity is compromised. We match existing brick and use proper lime-based mortar on pre-1925 masonry, so the repair moves with the original construction instead of fighting it. In Logan Square, that’s not a detail. It’s the difference between a repair that lasts five years and one that lasts thirty.

Common Chimney Liner & Rebuild Problems We See in Logan Square Homes
- Oversized flues causing draft failure and creosote glazing. Logan Square chimneys built for coal furnaces often measure 8×12 inches or larger. Modern gas appliances need a 5- or 6-inch round flue. Without proper liner sizing, exhaust cools too fast, condenses, and glazes the flue with corrosive creosote. We measure combustion appliances and flue dimensions before recommending any liner.
- Collapsed liners cross-venting between units in shared stacks. Because so many Logan Square two-flats and three-flats still share a single exterior chimney stack with separate flues per unit, a collapsed liner in one flue can vent combustion gases into an adjacent tenant’s flue. Our camera inspection protocol examines every flue in the stack, every time.
- Freeze-thaw damage to crowns and mortar joints. Chicago’s northwest-side neighborhoods like Logan Square experience 25-35 freeze-thaw cycles per year. Water infiltrates cracked crowns, expands when it freezes, and pops brick faces off the stack. Annual inspections catch this before rebuilds become necessary.
- Improper gas appliance venting into unlined brick flues. We still find high-efficiency furnaces venting directly into century-old brick. The acidic condensate eats the mortar from the inside out. A proper stainless liner protects the masonry and meets code.

FAQs - Chimney Liner & Rebuild in Logan Square
Because a collapsed liner in one flue can vent combustion gases into an adjacent tenant’s flue, creating a dangerous cross-venting hazard that the affected tenant may not detect until symptoms appear. We responded to a Logan Square three-flat on Kedzie Avenue where the second-floor tenant reported a sooty smell. Our camera inspection revealed that the original clay-tile liner in the first-floor flue had completely collapsed, dumping debris into the shared cleanout and pressurizing the third-floor flue. We installed a 6-inch DuraFlex stainless steel liner in all three flues and rebuilt the common crown with a copper chase cover to stop freeze-thaw damage. Every multi-unit stack in Logan Square gets this full inspection. Call (888) 289-6055 to schedule - estimates are free.
Yes, and it’s essential. A 1910 coal flue is typically 8×12 inches or larger; your new 96% efficient furnace needs a properly sized round liner, usually 5 or 6 inches. Without it, the exhaust cools too quickly in the oversized chamber, condenses, and creates glazed creosote while failing to establish adequate draft. We measure the appliance output and the flue dimensions, then install a DuraFlex stainless steel liner sized exactly to the manufacturer’s specification. Done right, and we stand behind it. Call (888) 289-6055 for an exact quote.
Freeze-thaw cycles are the primary cause in Logan Square, where 25-35 annual cycles force water to expand inside cracked mortar and porous brick. Lime mortar used before 1925 is particularly vulnerable; it was designed to breathe and flex, but decades of water infiltration without maintenance eventually spalls the brick faces and opens the joints. A proper rebuild uses compatible lime-based mortar and a sloped, overhanging crown with drip edges to shed water. We also recommend a chase cover on multi-flue stacks. Call (888) 289-6055 for a free inspection.
In most cases, yes. We drop the new stainless steel liner down the existing flue, either removing the damaged clay tile first or breaking it and removing the pieces through the cleanout. The exterior masonry stays intact. Only when the stack itself is structurally compromised, with widespread spalling and open mortar joints throughout, do we recommend partial or full rebuild. We’ll show you the camera footage and explain which category you’re in. No pressure. Call (888) 289-6055 for an honest assessment.
Annually, without exception. The combination of century-old clay tile, shared flue stacks, and modern high-efficiency appliances creates failure modes that develop faster than in single-family construction. Logan Square’s freeze-thaw exposure accelerates crown and mortar damage, which then admits water that deteriorates liners from the outside in. We document every inspection with photos and a plain-English verdict. The 90-Day Done Right Promise covers any work we perform. Schedule your annual inspection at (888) 289-6055.
