Call (844) 803-1545

We’ve been answering calls from Chicago homeowners since 1984. Russell Haines built Hearthstone Chimney Co. on the idea that a chimney craft is worth doing right - and that a live person should pick up the phone when you call (844) 803-1545, day or night. Our technicians carry HeatShield and Olympia Chimney materials on every truck, and most repairs finish in a single visit. Whether you’re in a 1920s bungalow near Belmont Cragin or a courtyard building off Milwaukee Avenue, we’ll give you photos you can see, a plain-English verdict, and a written estimate with no surprises on the bill.

Why Hearthstone Chimney Co. Is Chicago’s Preferred Chimney Repair Company

Chicago’s chimney problems are not generic. A company that learned its trade in a milder climate will miss what Lake Michigan’s east wind does to a south-facing crown, or why a Pilsen three-flat needs every flue in the stack scoped before anyone touches a brush. We’ve worked these neighborhoods for over 42 years, and our Chimney Cleaning & Sweep in Chicago crews bring that same hands-on expertise to every job. Russell Haines has personally trained our technicians on the coal-to-gas conversion failures that plague Chicago’s early 20th-century housing stock - the kind of institutional knowledge you can’t pick up from a manual.

Our customers in Chicago call us back because we document everything. The Level-2 camera inspection ends with photos on a tablet and a verdict you can understand without a engineering degree. The 90-Day Done Right Promise is backed in writing, no arguing - if it’s not right, we come back. That’s the Keystone Standard, and it’s governed by our K.E.Y.S. code: Krafted right, Every time, Your home first, Standing behind it.

A live person answers every call, 24 hours a day, 7 days a week. Not a callback queue. Not an app. When a chimney backs up smoke on a January night in West Town, you reach us, not a recording.

Our Chimney Repair Services in Chicago

Mortar Repointing & Tuckpointing

Chicago’s brutal freeze-thaw cycle - temperatures swinging from -15°F to 95°F in a single year - destroys mortar joints faster than in almost any other major Midwestern city. Moisture seeps into hairline cracks, freezes, and physically fractures the joint from within. In neighborhoods like Back of the Yards, where pre-1930 common brick dominates, we see mortar deterioration that would be unusual in Indianapolis or Milwaukee. Our Chimney Repair team grinds out failed joints to proper depth and repacks with color-matched, high-bond mortar rated for Chicago’s thermal stress. A typical mortar repointing job on a standard Chicago two-flat chimney runs $1,200-$2,800, depending on accessibility and how many courses need attention.

Spalling Brick Repair

Spalling - the flaking and crumbling of brick faces - is epidemic in Chicago because of that same freeze-thaw violence combined with decades of deferred maintenance on rental properties. We don’t slap sealant over active spalling and call it fixed. We cut out compromised brick, source matching replacement common brick when possible, and rebuild the affected courses with proper bond pattern and weep details. In Bridgeport and Pilsen, where many chimneys serve multiple converted flues, spalling often signals deeper liner failure underneath. We scope before we quote, so you know whether you’re looking at surface repair or a Chimney Liner & Rebuild - Chicago situation.

Chimney Waterproofing

Lake Michigan’s prevailing east winds drive rain and ice directly into south- and east-facing chimney openings across the Near North Side and lakefront wards. Standard waterproofing products fail here because they don’t account for wind-driven saturation. We apply professional-grade breathable sealants from Famco and Gelco that allow vapor to escape while blocking liquid water - critical in Chicago, where a January thaw can dump gallons of meltwater into a frozen stack. Waterproofing a typical Chicago chimney runs $800-$1,500 and carries our 90-Day Done Right Promise in writing.

Flashing Repair

Chicago’s flat-roof and low-slope additions, common on bungalow renovations and two-flat rear porches, create flashing geometries that confuse roofers who don’t specialize in chimneys. We fabricate custom step flashing and counterflashing from copper and coated steel, sealed with high-temp compounds that flex through thermal cycling without cracking. A straightforward flashing repair on a Chicago single-family home typically costs $180-$450; more complex jobs on multi-unit buildings with multiple roof planes run $600-$1,200. We also handle Chimney Cap & Crown in Chicago when the damage extends above the roofline.

Trusted Brands We Service in Chicago

We stock professional-grade materials from HeatShield, Gelco, Olympia Chimney, and Famco on every Chicago-area truck - no running to a supplier while your job sits half-finished. HeatShield’s cerfractory flue resurfacing system handles the acidic condensate damage we see in coal-converted gas flues across Pilsen and Bridgeport. Olympia Chimney’s stainless liners come in diameters that match Chicago’s undersized terra cotta without destructive masonry removal. Because we carry inventory locally, most Chicago repairs finish in one visit with the 90-Day Done Right Promise already in writing.

Common Chimney Repair Problems We See in Chicago Homes

• Coal-to-gas liner collapse in two-flats and three-flats. Chicago’s dense stock of early 20th-century brick multi-units - heavily concentrated in 60608 and 60609 across Pilsen, Bridgeport, and Back of the Yards - commonly left original terra cotta liners sized for coal combustion. Converted to gas, these undersized flues trap acidic condensate that crumbles the clay from the inside out. A sweeper in suburban Naperville rarely sees this failure mode at Chicago scale.
• Shared flue cross-contamination in bundled stacks. In Pilsen and Bridgeport, a single exterior chimney stack often carries three or four separate clay-tile flues - one per unit plus a boiler. Local techs know that cleaning one flue without checking its neighbors risks knocking debris across cracked partition walls into an adjacent active flue. We scope every flue in the stack on the same visit; it’s a liability issue we don’t gamble with.
• Crown failure from thermal shock. Chicago’s annual temperature swing of over 100 degrees fractures concrete crowns that were poured without proper expansion joints or reinforcing. We rebuild with poured crowns that include drip edges and proper slope, or we install Gelco pre-formed crowns where the masonry substrate allows.
• Wind-driven water intrusion on east and south faces. Lake Michigan’s unbroken fetch sends rain and ice directly into chimney openings on the lakeward side of buildings. Standard chimney caps with standard overhangs fail; we specify extended-depth caps and, where needed, custom shrouds that deflect wind-driven precipitation.
