We’ve been serving North Center for decades. The housing stock here is distinctive: dense blocks of Chicago bungalows and vintage multi-flats, most with original masonry chimneys built for coal heat and never properly adapted for natural gas. That history creates repair problems you won’t find in newer construction. Our Chimney Repair team knows what to look for, and we document every inspection with photos you’ll see and a plain-English verdict you’ll understand.
Why Hearthstone Chimney Co. of Chicago Is North Center’s Preferred Chimney Repair Company
We’ve served Chicago-area homeowners for over 42 years, and North Center has been central to our work since the beginning. The neighborhood’s concentration of century-old brick chimneys means we’ve repaired, rebuilt, or relined hundreds of them - on Byron Street, on Bell Avenue, on the blocks between Lincoln and the river. When you call us, you’re getting technicians who’ve seen your exact chimney configuration before.
Our customers in North Center mention the same things in their feedback: we show up when we say, we explain what we found without talking down, and we leave the work site clean. The 90-Day Done Right Promise is in writing, with no arguing - if something isn’t right, we come back and make it right. That’s been our standard since 2014.
Response time matters when you’re dealing with a leaking chimney or a suspected carbon monoxide issue. From our Chicago location, we can typically reach any North Center address within 30-50 minutes. We don’t use appointment windows that waste your afternoon. We give you a specific time, and we honor it.
Our Level-2 camera inspections are particularly valuable here. North Center’s chimneys often contain multiple clay tile flues in a single stack, and the damage is frequently hidden inside the wall where you can’t see it. We run a camera through every flue, show you the footage, and tell you exactly what it means for your safety and your repair options. No guesswork. No scare tactics.
Our Chimney Repair Services in North Center
Chimney Rebuilding
Some North Center chimneys have simply reached the end of their service life. The combination of 110-year-old lime mortar, decades of freeze-thaw damage, and undersized coal-era flues venting modern gas appliances can leave a chimney structurally unsound. When we rebuild, we use new brick matched to the original profile and professional-grade materials from Olympia Chimney and Copperfield. We rebuild the stack from the roofline up, or from the foundation if necessary, and we always install a proper crown with positive drainage to protect the new work. A full rebuild in North Center typically runs $2,800-$3,800.
Mortar Repointing & Tuckpointing
Repointing is our most common repair in North Center, and for good reason. The neighborhood’s original lime-mortar joints deteriorate faster than Portland cement in Chicago’s climate, and once water gets behind the face bricks, freeze-thaw cycling pops them off in sheets. We grind out the failed mortar to proper depth, match the original composition and color, and repoint with materials appropriate for vintage masonry. Done correctly, repointing preserves the chimney’s structural integrity and prevents the costlier rebuild that comes from waiting too long. Expect $850-$1,800 for most North Center repointing jobs.
Flashing Repair
Flashing is the metal seal where your chimney passes through the roof, and it’s a chronic leak point on North Center’s older homes. Original flashing was often lead or galvanized steel that has corroded, pulled away, or been damaged by repeated thermal expansion. We fabricate custom flashing from long-lasting materials and seal it with professional-grade compounds. Because many North Center homes have had multiple roof layers added over the decades, we often find the flashing buried under shingles or improperly integrated with the roofing system. We fix it correctly, with photos to show you before and after. Flashing repair in North Center generally costs $450-$950.
Spalling Brick Repair & Chimney Waterproofing
Spalling - the flaking and crumbling of brick faces - is everywhere you look in North Center after a hard winter. It’s caused by water freezing inside the brick’s pores, expanding, and breaking the surface. Once spalling starts, it accelerates. We remove and replace spalled bricks with matching units, then apply a breathable silane/siloxane waterproofing treatment that lets moisture escape while blocking new water entry. We use HeatShield and Gelco products formulated specifically for historic masonry. This combined repair and protection typically runs $1,200-$2,400 for a standard North Center chimney.

Trusted Brands We Service in North Center
We don’t use builder-grade substitutes. For North Center’s demanding conditions - freeze-thaw cycling, high humidity from the nearby North Branch, and the acidic condensate produced in oversized unlined flues - we specify professional-grade materials from brands that have proven themselves in this climate. We stock DuraFlex stainless steel relining systems for the coal-era flues common in North Center bungalows, HeatShield cerfractory resurfacing for deteriorated clay liners, and Gelco waterproofing compounds formulated for breathable historic masonry. Because we keep these materials on hand, most North Center repairs don’t wait for parts. We diagnose, we show you the photos, and we fix it.
Common Chimney Repair Problems We See in North Center Homes
- Acidic condensate destroying unlined coal-era flues. When North Center homes converted from coal to natural gas in the 1940s-1960s, the oversized flues were rarely relined. Lower-temperature gas exhaust condenses on the clay tile, producing sulfuric acid that eats mortar joints and cracks tiles. We find this on virtually every block.
- Freeze-thaw destruction of exposed brick and crowns. Chicago’s winter temperatures cross 32°F dozens of times, and each cycle pumps water deeper into the masonry. North Center’s chimneys, exposed above the roofline without the protection of suburban setbacks, take the full force. Spalled bricks and crumbled crowns are the result.
- Multi-unit cross-contamination in shared chimney stacks. In North Center’s two-flats and three-flats, a single chimney often contains multiple clay tile flues serving different units. A crack in one flue can leak carbon monoxide into an adjacent flue or living space. This is a recurring code issue that generalist inspectors frequently miss.
- Water infiltration from failed flashing and deteriorated crowns. The combination of aged roofing, multiple roof layers, and original lime-mortar crowns that have eroded to powder creates multiple entry points for water. We trace the source, show you the path, and seal it permanently.

FAQs - Chimney Repair in North Center
Most original coal chimneys in North Center can be saved with relining rather than full rebuild, provided the exterior masonry is still structurally sound. We install a DuraFlex stainless steel liner sized for your current gas appliances, which seals the flue, improves draft, and meets modern safety codes. A full rebuild is only necessary when the exterior stack has extensive spalling, leaning, or mortar loss that compromises structural integrity. Call (888) 289-6055 and we’ll inspect it - estimates are free.
Yes, and this is a known hazard in North Center’s two-flats. A single chimney stack often contains separate clay tile flues for each unit, but the partition between them can deteriorate and allow flue gases to cross from one unit to another. We worked on a 1920s greystone two-flat on Montrose Avenue where the lower unit’s gas furnace was backdrafting into the upper unit’s living room. The shared chimney had two clay tile flues - one for each unit - and the partition between them had deteriorated. We relined both flues with DuraFlex stainless steel liners, resolving the cross-contamination and bringing the system up to modern safety codes. If you’re experiencing smoke or odors from another unit, call us immediately - this is not a wait-and-see situation.
We recommend annual Level-2 camera inspections for North Center homes, and every six months if your chimney is unlined or over 80 years old. Chicago’s aggressive freeze-thaw cycling, with temperatures crossing 32°F dozens of times each winter, accelerates mortar deterioration and crown failure. The neighborhood’s proximity to the North Branch of the Chicago River also introduces above-average ambient moisture that compounds condensation inside under-insulated flues. An annual inspection catches spalling, liner cracks, and flashing failures before they become expensive rebuilds. Call (888) 289-6055 to schedule - our $89 seasonal tune-up includes a basic inspection.
Breathable silane/siloxane penetrating sealers are the correct choice for North Center’s century-old brick. These compounds fill the pores to block liquid water while allowing water vapor to escape - critical because trapping moisture inside vintage masonry accelerates freeze-thaw damage. We use Gelco professional-grade waterproofing, applied after any spalled bricks are replaced and mortar joints are repointed. Never use film-forming sealers on historic chimneys; they create a barrier that holds water in and causes more damage than no treatment at all. Most North Center waterproofing jobs run $800-$1,400 depending on chimney size and accessibility.
Almost certainly yes. Your original coal-era flue is oversized for a gas insert, which means exhaust cools too quickly, condenses, and produces corrosive acidic moisture that destroys the clay tile. The insert manufacturer will specify a minimum flue size, and we typically need to install a stainless steel liner from the insert to the top of the chimney. We also inspect the existing structure for cracks, missing mortar, and proper clearance to combustibles - common issues in North Center’s 100-year-old chimneys. The modification typically costs $1,800-$2,800 and is required for warranty coverage on most inserts. Call (888) 289-6055 before you buy the insert, and we’ll tell you exactly what your chimney needs.
