Fast, Reliable Chimney Liner & Rebuild Across Flossmoor
Chimney liner replacement and chimney rebuild in Flossmoor typically costs between $2,800 and $8,500 depending on whether you’re relining a single flue or rebuilding a combination chimney serving both fireplace and furnace. Most Flossmoor homeowners with mid-century homes near the Country Club corridor need liner work, not full rebuilds, though freeze-thaw damage to crowns and brickwork is common after 50-70 years of service. We answer calls live at (888) 289-6055, and our technicians are usually on Flossmoor streets like Braemar Road, Flossmoor Road, or Western Avenue within 45 minutes of dispatch.
We’ve worked on chimneys in Flossmoor for decades. We know the village’s housing stock - substantial brick colonials and ranches built from the 1950s through the 1970s, many with combination flues that served original oil burners and still serve modern gas equipment. That specific combination creates problems generic chimney companies miss. Our Chimney Liner & Rebuild team documents every inspection with photos you’ll see and a plain-English verdict you can understand. No jargon, no upsell.
Why Hearthstone Chimney Co. of Chicago Is Flossmoor’s Preferred Chimney Liner & Rebuild Company
Flossmoor homeowners call us back because we show up when we say, explain what we found in plain language, and put our guarantee in writing. We’ve served the south suburbs for over 42 years, and our technicians know the difference between a Braemar Road colonial with a shared flue and a newer home on the east side with separate stacks.
Our reviews from Flossmoor customers consistently mention the same things: the technician arrived in a marked truck and uniform, took photos of the flue interior with a Level-2 camera, and explained why the liner was failing without pushing unnecessary work. We don’t quote full rebuilds when a stainless steel liner will solve the problem. That’s the 90-Day Done Right Promise - in writing, no arguing.
We don’t subcontract to random crews. Our background-checked technicians carry DuraFlex and Olympia Chimney materials on their trucks, so most liner jobs in Flossmoor finish in a single visit.
We also understand Flossmoor’s specific conditions: the mature tree canopy that shades chimney tops until mid-morning, the 30-plus freeze-thaw cycles every winter that punish crowns and mortar, and the oversized original flues that cause condensation problems in homes that converted from oil to gas. Local knowledge matters when you’re diagnosing draft failure versus liner failure.
Our Chimney Liner & Rebuild Services in Flossmoor
Stainless Steel Liner Installation
Flossmoor’s combination flues - originally sized for oil burners and wood fireplaces - are almost always too large for modern high-efficiency gas appliances. An 8×8 clay tile flue connected to a 80,000 BTU gas furnace creates a lazy draft that condenses moisture inside the liner all winter. That moisture freezes in the tile joints during Flossmoor’s repeated freeze-thaw cycles, spalling the clay and opening gaps.
We install 316Ti stainless steel liners from DuraFlex and Olympia Chimney, properly sized to each appliance. For Flossmoor’s shaded flues, we specify insulated wraps that maintain flue temperature on cold mornings when the tree canopy delays warming. On a colonial home on Braemar Road, we relined a combination flue that was 8×8 tile (oversized for the gas furnace), causing condensation and spalling. We installed a 6-inch DuraFlex stainless steel liner with an insulated wrap, restoring draft and eliminating moisture issues.

Flexible Liner Installation
Not every Flossmoor chimney is straight. Mid-century builders sometimes offset flues around staircases or structural beams, especially in the ranch homes south of Flossmoor Road. Rigid liners won’t navigate these offsets without breaking tile or leaving dangerous gaps.
Our flexible liners from DuraFlex conform to gradual offsets while maintaining the smooth interior surface that resists creosote buildup. For Flossmoor homes with pre-WWII construction near the original village core, where flues may have settled or shifted over 80-plus years, flexible installation is often the only viable relining method without major masonry demolition. We camera-inspect first to map the flue path, then size the flexible liner precisely.

Liner Replacement
When clay tile liners in Flossmoor homes reach end of life - cracked, spalled, or missing sections - replacement is non-negotiable for safety. The National Fire Protection Association requires intact, properly sized flue liners for all solid fuel and gas appliances. We don’t patch partial failures.
Our liner replacement process in Flossmoor starts with a Level-2 camera inspection that you watch with us. We document cracked crowns, deteriorated mortar joints, and tile displacement caused by decades of freeze-thaw stress. Then we remove failed sections and install new stainless steel liners sized to your actual appliances, not the original 1950s specifications. The new liner drops into place through the existing flue, minimizing disruption to your brickwork and living space.

Partial Chimney Rebuild
Some Flossmoor chimneys need more than a liner. When the crown has cracked completely through, when brick faces spall off in sheets after winter, or when the top courses lean from failed mortar, we rebuild from the roofline up. This is common on homes that haven’t had crown maintenance in 20-plus years.
Our partial rebuilds in Flossmoor use matching brick where possible and always include a poured concrete crown with proper drip edge and expansion relief. We integrate the new crown with your stainless steel liner termination, creating a system that sheds water instead of trapping it. The 90-Day Done Right Promise covers both liner and rebuild work - one call, one accountability.

Trusted Brands We Service in Flossmoor
We stock professional-grade materials from DuraFlex, HeatShield, and Olympia Chimney on our south suburban trucks, which means Flossmoor homeowners aren’t waiting two weeks for parts to ship. DuraFlex stainless steel liners carry a lifetime warranty when properly installed. HeatShield’s cerfractory resurfacing system lets us restore sound but pitted clay flues in certain Flossmoor homes where full replacement isn’t necessary. Olympia Chimney’s insulated liner systems solve the draft problems we see repeatedly in Flossmoor’s tree-shaded chimneys. We don’t use builder-grade substitutes or generic brands that won’t stand up to Chicago’s freeze-thaw cycling. The materials matter as much as the installation.
Common Chimney Liner & Rebuild Problems We See in Flossmoor Homes
- Oversized combination flues causing chronic condensation. Your 1960s Flossmoor home likely has an 8×8 or 8×12 clay flue originally sized for an oil burner and open fireplace. Modern gas appliances need 5-inch or 6-inch diameter. The mismatch creates a cold, slow draft that condenses acidic moisture inside the liner year-round.
- Glazed creosote from shaded, slow-warming flues. Flossmoor’s mature oak and maple canopy keeps many chimney tops in shadow until 10 a.m. or later. Cold flue walls don’t establish draft quickly, so smoke lingers and creosote bakes onto the upper tile sections in a hard, glazed layer that’s difficult to remove and highly combustible.
- Freeze-thaw destruction of crowns and brick faces. Thirty or more freeze-thaw cycles each winter saturate porous brick and mortar, then expand the water as it freezes. We see spalled brick faces and cracked crowns on virtually every uninspected Flossmoor chimney over 40 years old.
- Draft failure mistaken for “just a windy day.” Flossmoor homeowners often tell us their fireplace “never draws right in the morning.” It’s not wind. It’s an uninsulated, oversized flue that can’t establish temperature differential against cold air being pulled down from the shaded chimney top. The right liner with proper insulation fixes this permanently.

FAQs - Chimney Liner & Rebuild in Flossmoor
Yes, we regularly install combination liners in Flossmoor’s mid-century homes, sizing each branch correctly for the appliance it serves. We typically drop a stainless steel liner with a wye connector that maintains proper draft for both your gas furnace and fireplace, eliminating the condensation problems caused by the original oversized clay flue. Call (888) 289-6055 to schedule a camera inspection - estimates are free.
Most Flossmoor homeowners need a liner, not a rebuild, if the brickwork and crown are structurally sound. Spalling clay tile is expected after 50-70 years and is exactly what stainless steel liners are designed to solve. We camera-inspect to confirm the masonry condition before recommending any rebuild work. Call (888) 289-6055 and we’ll show you the photos so you can decide with full information.
Your flue is cold from overnight temperature drop and shaded by Flossmoor’s tree canopy, so it can’t establish upward draft before you light the fire. Smoke and cold air reverse direction until the flue warms, which takes longer in shaded chimneys. An insulated stainless steel liner maintains temperature and establishes draft immediately, eliminating morning smoke rollout and the glazed creosote that forms during those weak-draft burns. Call (888) 289-6055 for a liner evaluation.
Yes, and in Flossmoor it’s often urgent. Your original clay flue was sized for an oil burner that ran at higher temperature and larger volume. The new gas appliance runs cooler with less flow, so the oversized flue stays cold, condenses acidic moisture, and destroys the remaining clay tile from the inside out. We’ve replaced liners in Flossmoor homes where the combination flue was intact above the roofline but completely deteriorated below - invisible without a camera inspection. Call (888) 289-6055 for a free evaluation.
We replace with stainless steel rather than patching clay tile. Individual clay tile repair in Flossmoor’s combination flues is temporary at best - the underlying problem is incorrect flue size for modern appliances, and new tile in an oversized flue will fail the same way. Our stainless steel liners from DuraFlex and Olympia Chimney carry lifetime warranties and solve the root cause. Call (888) 289-6055 for pricing on your specific flue configuration.
