Why Hearthstone Chimney Co. of Chicago Is Flossmoor’s Preferred Chimney Repair Company
We’ve been answering calls from Flossmoor homeowners since 2014, back when many of these chimneys were still young. That longevity means something in a village where people stay put for decades. We’ve rebuilt crowns on homes near Heather Hill and repointed stacks along Sterling Avenue enough times that we recognize the brick patterns before we unload the ladder.
Our reputation here is built on documentation, not promises. Every Level-2 inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics. The estimate you sign is the number on the invoice. Period.
Response time to Flossmoor is typically same-day or next-morning, depending on call volume and weather. We’re not fighting traffic from the far north side; our dispatch routes south suburban calls with intent.
And we know what we’re looking at. Flossmoor’s housing stock - substantial brick colonials and ranches built in the 1950s through 1970s for the country-club community - means a large share of chimneys were originally constructed as combination flues serving both a wood-burning fireplace and an oil or gas furnace in a single masonry chase. Now 50-70 years old, those original clay tile liners are at or past their design life, and the flues are almost always oversized for the modern gas appliances that replaced the old oil burners, creating chronic condensation, liner spalling, and draft failure that owners mistake for a “drafty fireplace.” Generic inspectors miss this pattern. We don’t.
Our Chimney Repair Services in Flossmoor
Mortar Repointing
The 30-plus freeze-thaw cycles that hit Flossmoor each winter grind away at mortar joints above the roofline faster than homeowners expect. We grind out failed joints to proper depth and repoint with color-matched, professional-grade mortar formulated for Chicago’s climate swings. Done right - and we stand behind it.

Spalling Brick Repair
Spalled brick faces are the norm on uninspected Flossmoor chimneys in the 50-70 year range. Water enters through failed crowns or open joints, freezes, and pops the face right off the brick. We remove damaged units and install matching replacements, then seal the crown to stop the cycle. Most spalling repairs on Flossmoor’s mid-century stock run $650-$1,400.

Chimney Waterproofing
Flossmoor’s mature tree canopy is beautiful. It also keeps masonry damp longer after rain, accelerating deterioration. We apply vapor-permeable waterproofing agents that let the chimney breathe while shedding water - critical on shaded stacks throughout the village’s heavily wooded residential streets.

Flashing Repair
Step flashing and counterflashing on Flossmoor’s older homes often predates modern ice-and-water shield standards. We fabricate and install custom flashing that integrates with existing roofing, sealed with professional-grade compounds. No leaks, no callbacks.

Chimney Rebuilding
When freeze-thaw damage, liner failure, or long-deferred maintenance compromise structural integrity, partial or full rebuild becomes the square deal. We rebuild to current code using matching brick and proper crown construction, documented with photos at every stage. A full rebuild on a typical Flossmoor combination-flue chimney runs $3,500-$7,500.

Tuckpointing
Tuckpointing is our most called-for service in Flossmoor, and for good reason. The village’s brick chimneys were built with mortar that has simply aged out. We tuckpoint with precision - removing to 3/4-inch depth, cleaning, and repointing with mortar matched for strength and color. It’s painstaking work. Anything less is a temporary patch.

Common Chimney Repair Problems We See in Flossmoor Homes
- Combination flues with oil-to-gas conversion cause chronic condensation and liner spalling when oversized for modern appliances. The original flue was sized for an oil furnace’s hotter exhaust. The replacement gas appliance runs cooler, exhaust moves slower, and moisture condenses on the oversized clay tiles. Year after year, this spalls the liner surface and degrades draft. We see this pattern constantly in Flossmoor’s 1960s-era colonials.
- Shaded chimneys from heavy tree canopy produce glazed creosote deposits on upper tiles, often overlooked by generic inspections. In Flossmoor, the mature tree canopy keeps many chimney tops shaded into late morning, slowing flue warm-up and causing heavy glazed creosote buildup on the upper tile sections - especially during early-season fires in October and March. This glazed creosote is a fire hazard and a draft killer. Our camera inspections catch it.
- Failed crown mortar and spalling brick from 30-plus annual freeze-thaw cycles degrade above-roofline masonry rapidly if not tuckpointed promptly. The crown is the chimney’s umbrella. Once it cracks, water enters every freeze-thaw cycle. We repaired a combination flue on a 1960s brick colonial near Flossmoor Country Club. The original clay tile liner was spalling from decades of freeze-thaw and oversized for the modern gas furnace; we installed a HeatShield liner system to restore draft and seal the chase.
- Late-season fires in cold flues deposit heavy creosote loads on already-compromised liners. Flossmoor homeowners lighting their first October fire or a March weekend burn face cold, sluggish flues that don’t draft properly until well into the burn. The result is incomplete combustion and accelerated creosote accumulation in the upper flue, right where the tree shade already suppresses temperatures.

FAQs - Chimney Repair in Flossmoor
Yes, both flues in a combination chimney should be inspected and repaired as needed, because they share the same masonry structure and liner failure in one flue compromises the entire chase. In Flossmoor’s 1950s-1970s housing stock, the furnace flue is often the more deteriorated of the two - oversized for modern gas appliances and suffering from condensation damage hidden from casual view. Our Level-2 camera inspection examines both passages and documents findings with photos you can see. Call (888) 289-6055 for a free inspection.
Spalling brick is extremely common on Flossmoor chimneys that haven’t been tuckpointed in the last 15-20 years, given the 30-plus annual freeze-thaw cycles in the Chicago south suburbs. Water enters through cracked crowns or open mortar joints, freezes overnight, and fractures the brick face. It’s not cosmetic - it accelerates rapidly once started. We address the source (usually crown or mortar failure) before repairing brick, or you’ll be doing it again. Call (888) 289-6055 - estimates are free.
Yes, Flossmoor’s dense tree canopy is a documented cause of weak morning draft and glazed creosote buildup on upper flue tiles. Shaded chimneys warm more slowly on cold days, suppressing the temperature differential that drives draft. Early-season fires in October or March are especially affected, when ambient temperatures are marginal and the flue needs every degree of warmth to establish proper draw. We verify draft performance during inspection and can recommend solutions from flue insulation to liner sizing corrections. Call (888) 289-6055 to schedule.
Yes, tuckpointing is one of our most performed services in Flossmoor and is included in our standard repair capabilities. We grind out failed mortar to proper depth, clean joints thoroughly, and repoint with color-matched, climate-appropriate mortar. Most Flossmoor tuckpointing jobs are completed in a single visit. The 90-Day Done Right Promise covers all our tuckpointing work in writing, with no arguing. Call (888) 289-6055 for an exact quote - estimates are free.
Yes, we regularly reline combination flues in Flossmoor homes that have converted from oil to gas, using HeatShield cerfractory systems or DuraFlex stainless liners sized correctly for modern appliances. The original clay tile is almost always oversized for today’s gas equipment, causing the condensation and draft problems we see throughout the village. We size the new liner to the appliance, not the chimney, which restores proper draft and stops further liner deterioration. Call (888) 289-6055 - we’ll inspect both flues and give you a plain-English verdict with photos.
