Our Chimney Repair Services in Forest Park
Chimney Rebuilding
Sometimes a century-old chimney in Forest Park has deteriorated past the point where spot repairs will hold. When the structure is compromised from the roofline up, we rebuild using matching brick and professional-grade materials from Olympia Chimney and Copperfield. We recently completed a full rebuild on a bungalow near Harlem Avenue where the original chimney had settled and cracked through multiple freeze-thaw cycles. The homeowner wanted it done right so she’d never think about it again. That’s the job we aim for every time.
Spalling Brick Repair
Spalling, the flaking and crumbling of brick faces, is epidemic on Forest Park’s pre-war chimneys. The combination of coal soot residue, moisture intrusion, and Chicago’s harsh freeze-thaw cycles destroys the outer layer of brick. Last fall we repaired a two-flat on Marengo Avenue where the original 1920s furnace flue liner had cracked from decades of coal soot residue and freeze-thaw. We relined the shared chimney chase with a DuraFlex 316L stainless steel liner, capping the abandoned furnace flue to prevent moisture intrusion into the fireplace flue. The spalling stopped because we addressed the source, not just the symptom.
Tuckpointing
Mortar joints on century-old brick chimneys in Forest Park deteriorate from thermal stress during long heating seasons running October through April. Tuckpointing, the careful removal and replacement of failed mortar, is often a prerequisite before other repairs can hold. On the bungalow blocks near Roosevelt Road, we regularly find joints eroded to powder that must be rebuilt before we can address liner or cap issues. We color-match the new mortar to the original so the repair disappears into the facade.
Chimney Waterproofing
Forest Park’s Lake Michigan-influenced weather patterns mean chimneys absorb more moisture than those in drier climates farther west. We apply breathable, professional-grade waterproofing agents that allow trapped vapor to escape while blocking liquid water. This is especially critical on bungalows where the chimney sits exposed above a low-pitched roof and takes the full force of every storm.
Flashing Repair
The junction where chimney meets roof is a common leak point on Forest Park’s older homes. Original flashing, often lead or galvanized steel from the 1920s-1940s, fatigues and separates. We install new flashing integrated with your roofing system, sealed with materials rated for the temperature swings these chimneys endure.

Trusted Brands We Service in Forest Park
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Forest Park customers, this means we stock liners, caps, and repair compounds sized for the oversized coal-era flues common in the village, not just standard modern dimensions. When we arrive for your job, we have what we need. Most repairs finish in one visit.
Common Chimney Repair Problems We See in Forest Park Homes
- Oversized coal-era flue liners left uncapped after gas conversion. When Forest Park homeowners upgrade to high-efficiency furnaces, they routinely abandon the old furnace clay-tile flue without properly capping or relining it. This leaves an open, uncapped passage inside the shared chimney chase that accelerates moisture damage and spalling in the adjacent fireplace flue. We encounter this failure mode repeatedly on the village’s bungalow blocks.
- Original 4-inch clay tile liners cracked and spalled from coal soot and freeze-thaw. The 1910s-1940s bungalows and two-flats throughout ZIP code 60130 contain clay tile liners that have endured a century of thermal cycling. The coal soot residue left behind accelerates deterioration, and Chicago’s freeze-thaw cycles finish the job.
- Mortar joints deteriorated from thermal stress during long heating seasons. Forest Park’s heating season runs hard seven months a year. The repeated expansion and contraction of century-old brick and original mortar eventually grinds the joints to powder, requiring tuckpointing before any lasting repair can be made.
- Moisture intrusion from failed crowns and inadequate caps. The concrete crowns topping many Forest Park chimneys have cracked from decades of exposure. Without a sound crown and proper cap, water enters the chase, accelerates spalling, and damages interior flue liners.

FAQs - Chimney Repair in Forest Park
Because Forest Park’s dense concentration of 1910s-1940s brick bungalows means nearly every chimney repair job involves legacy coal-era flues that are oversized for modern gas furnaces, often with unlined or spalled clay tiles that require liner evaluation before any repair. The original 4-inch clay tile liners in these structures are frequently cracked after a century of coal soot residue and freeze-thaw cycling. We inspect the liner as a standard step, not an upsell, because repairing mortar or brick over a failed liner wastes your money. Call (888) 289-6055 to schedule - estimates are free.
Yes, and this is one of the most common failure patterns we see in Forest Park. When homeowners upgrade to high-efficiency furnaces and abandon the old furnace clay-tile flue without capping or relining it, they leave an open passage inside the shared chimney chase. Moisture enters freely, accelerates spalling in the adjacent fireplace flue, and can damage the chimney structure from within. We cap abandoned flues with proper termination fittings and can install a DuraFlex liner if the fireplace flue still serves a wood-burning or gas insert. Call (888) 289-6055 for an inspection.
Most Forest Park chimneys need tuckpointing every 15-25 years, though we’ve seen century-old mortar fail faster after severe winters or previous substandard repairs. The long heating seasons and brutal freeze-thaw cycles in this Lake Michigan-influenced climate grind mortar joints to powder. We inspect mortar condition during every service and will tell you plainly whether repointing can wait or needs to happen before winter. Call (888) 289-6055 for a free evaluation.
Often yes, if the structural integrity of the chimney is sound and the spalling is limited to the outer brick faces. We remove damaged brick, address the moisture source (usually failed flashing, crown, or an uncapped abandoned flue), and replace with matching brick. If the spalling has compromised the structural wythes or the chimney leans, partial or full rebuilding becomes necessary. We’ve completed both spot repairs and full rebuilds on Circle Avenue and surrounding blocks. Call (888) 289-6055 and we’ll photograph and explain exactly what your chimney needs.
We primarily install DuraFlex 316L stainless steel liners for the oversized, coal-era flues common in Forest Park bungalows and two-flats, with HeatShield cerfractory resurfacing for liners with minor cracking that don’t require full replacement. Both are professional-grade products we stock in dimensions suited to these older structures, not just standard modern sizes. The right liner, properly sized and installed, prevents the moisture and draft problems that destroy chimneys from within. Call (888) 289-6055 to discuss which option fits your flue condition.
