We’ve been driving down Pulaski Road and Cicero Avenue to reach Ashburn homes for over 42 years. The brick bungalows that define this neighborhood - the ones between 79th Street and 87th, from Kedzie west toward Central Park - carry chimneys that are now 70 to 100 years old. We know the freeze-thaw damage these chimneys take every winter, the coal-era flues that no longer meet code, and the way a cracked crown can let water run straight down into your living room. When you call Hearthstone, you get a live person on the phone, 24 hours a day. We’ll be there when we say.

Our Chimney Repair Services in Ashburn
Mortar Repointing
The mortar joints in an Ashburn bungalow chimney have endured 80 to 100 Chicago winters. Each freeze-thaw cycle - and we get dozens every year - drives water deeper into porous mortar. When it expands, the joint crumbles. Left alone, loose bricks follow, then leaning walls, then a rebuild you didn’t budget for.
We grind out deteriorated mortar to proper depth and repoint with color-matched, professional-grade mortar formulated for Chicago’s climate. Done right, repointing adds decades of life. A typical mortar repointing job on an Ashburn bungalow chimney runs $850-$1,800.
Spalling Brick Repair
Spalling - when brick faces flake and pop off - is everywhere we look in Ashburn’s older chimneys. The combination of aged, porous brick and aggressive freeze-thaw at the crown and upper courses destroys the protective brick skin. We see this especially on bungalows near 83rd and Pulaski, where chimneys catch full west wind.
We replace spalled bricks with matching reclaimed or new brick where possible, then address the water source. Without stopping the water, new brick spalls too. Spalling brick repair on an Ashburn chimney typically costs $650-$1,400.
Chimney Waterproofing
Ashburn’s brick is thirsty. Decades of exposure have opened pores that suck in rainwater and melting snow. We apply vapor-permeable waterproofing sealants that let the chimney breathe while blocking liquid water. This isn’t a DIY spray job. We use professional-grade formulations, applied after any needed mortar or brick repair, with full attention to the crown, cap, and flashing details. Waterproofing a typical Ashburn bungalow chimney runs $400-$900.
Flashing Repair
The intersection where your chimney punches through the roof is the most leak-prone spot on most Ashburn homes. Original flashing on these bungalows was often galvanized steel, now rusted through, or was poorly sealed during a roof replacement years ago. We fabricate and install custom step flashing and counterflashing, sealed with professional-grade compounds. Flashing repair in Ashburn typically runs $350-$750.
Chimney Rebuilding
Sometimes the damage has gone too far. When an Ashburn chimney leans, has extensive spalling through multiple courses, or has a failed structural base, partial or full rebuilding is the only safe path. We dismantle carefully, salvage what brick we can, and rebuild to current code with proper crowns, caps, and liners. A partial rebuild runs $2,200-$4,500; full rebuilds on Ashburn bungalows range $4,500-$8,500.
Tuckpointing
For chimneys where mortar damage is early and localized, tuckpointing targets specific joints before the problem spreads. It’s preventive maintenance that saves Ashburn homeowners from costlier repairs down the road. Tuckpointing jobs start around $450-$950.

Trusted Brands We Service in Ashburn
We don’t use builder-grade substitutes. Our Ashburn repairs rely on professional-grade materials from DuraFlex, HeatShield, Gelco, and Olympia Chimney - brands that hold up in Chicago’s punishing climate. We stock liners, caps, and repair compounds locally, so most Ashburn jobs don’t wait on parts. When we installed that DuraFlex liner on Kedvale Avenue, the stainless steel coil was on our truck already. That’s how most jobs get done in a single visit.
Common Chimney Repair Problems We See in Ashburn Homes
- Mortar joints spalled by freeze-thaw cycles. Chicago’s winter temperature swings - above freezing by afternoon, below by evening - push water through Ashburn’s aged mortar joints repeatedly. The mortar turns to sand. Bricks loosen. Water finds its way to your ceiling.
- Oversized coal-era flues left unlined after gas conversion. Your bungalow’s chimney was built for a coal furnace that needed an 8×13 or larger flue. Your gas furnace needs a fraction of that volume. An unlined, oversized flue drafts poorly, condenses acidic moisture, and can allow carbon monoxide to spill into your home.
- Cracked clay tile liners hidden from view. The original clay tiles in Ashburn chimneys have survived decades of thermal stress. Many are cracked, shifted, or missing entirely. You won’t see this from the ground. A Level-2 camera inspection reveals what the eye cannot.
- Crown failure from age and poor original construction. Many Ashburn bungalow crowns were poured thin, without proper reinforcement or overhang. They crack, they slope toward the flue instead of away, and they funnel water straight into the chimney structure every rain.

We recently repointed the crown and installed a DuraFlex liner for a 1940s bungalow on Kedvale Avenue. The original clay tiles were cracked from decades of heat cycling, and the flue was 8×13 - way too big for the new gas furnace. Ashburn’s freeze-thaw had spalled the top three courses of brick. The homeowner had no idea until the HVAC contractor flagged the code issue mid-project. We completed the liner and masonry repair in two days. Done right, and we stand behind it.

FAQs - Chimney Repair in Ashburn
Yes. Chicago building code requires your chimney flue to be properly sized and lined for any new furnace or boiler installation. Most Ashburn bungalows have oversized coal-era flues that are far too large for modern high-efficiency gas equipment. An unlined, oversized flue drafts poorly and can allow carbon monoxide to enter your home. We install stainless steel liners from DuraFlex that match your new appliance exactly. Call (888) 289-6055 before your HVAC project starts - we’ll inspect and quote so you’re not caught off guard mid-job.
Chicago’s freeze-thaw cycle is the culprit. Water seeps into micro-cracks in the crown, freezes overnight, and expands with enough force to split concrete. Ashburn’s older bungalow crowns were often poured too thin and without proper reinforcement, so they fail faster than newer construction. We rebuild crowns with proper slope, overhang, and professional-grade compounds that shed water instead of absorbing it. A rebuilt crown with correct detailing typically lasts 20+ years.
Yes. We replace spalled bricks with matching units and repoint surrounding mortar to restore structural integrity and appearance. Spalling in Ashburn is almost always caused by water infiltration through failed mortar joints or a cracked crown, so we also fix the source. Otherwise new brick spalls too. Most spalling brick repairs on Ashburn chimneys run $650-$1,400 and are completed in one visit.
Measure the flue opening and compare it to your appliance’s requirements - or better, have us inspect it with our Level-2 camera. Most Ashburn coal-era flues are 8×12 inches or larger. A modern 80,000 BTU furnace needs roughly a 5-inch round liner. If your flue is more than double the required area, it’s oversized. Poor draft, condensation stains on the chimney exterior, or a furnace that won’t stay lit are warning signs. We document what we find with photos you can see and give you a plain-English verdict.
Mortar repointing and crown repair. The combination of 80- to 100-year-old mortar and Chicago’s aggressive freeze-thaw destroys joints and crowns faster than in newer suburbs. We repoint more chimneys in Ashburn’s bungalow belt than anywhere else we serve. Annual inspection catches this early, before loose bricks and water damage escalate to a full rebuild.
