Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

AfterFast, Reliable Chimney Repair Across Chicago
Chimney repair in Chicago typically costs $800-$4,500 depending on scope, with mortar repointing starting around $1,200 and full chimney rebuilding ranging $3,500-$8,000 for a standard bungalow stack. Most inspections are scheduled within 48 hours, and our Chimney Repair in Chicago crews dispatch from our local metro office. Call (708) 234-1174 for a written estimate before any work begins.
We’ve provided Chimney Cleaning & Sweep - Chicago services since 2009 - more than 38,000 inspections and cleanings, every one with a camera down the flue and a written price before the first brick gets touched. Chicago’s housing stock is unlike anywhere else in the Midwest: roughly 80,000 brick bungalows built between 1910 and 1940, most with original coal-era chimneys that were later converted to gas without proper relining. That specific problem - oversized, unlined or improperly transitioned flues - is what we find most often, and it’s where homeowners get upsold work they don’t need. We don’t quote repairs until we’ve shown you the camera footage. That’s Clause 4 of the Haven Standard, and we’ve operated that way since day one.
Why Level Two Chimney Evanston Is Chicago’s Preferred Chimney Repair Company
Our reputation in Chicago is built on documentation, not promises. Every job starts with an NFPA 211 Level 2 inspection: camera-scan, photo record, written scope, written price, written warranty. The 365-Day Done Right Promise backs it all - if it’s not right, we make it right. Homeowners in neighborhoods from Rogers Park to Beverly know our technicians by the uniform, the license number on the page, and the text that hits their phone when we’re en route.
Response time to Chicago addresses averages 24-48 hours for standard repairs. Emergency calls - active leaks, structural instability, or blocked flues venting carbon monoxide - get prioritized same-day when safety is at stake. Our crews know the local conditions: lake-saturated brick, freeze-thaw cycles that hit harder than in Joliet or Naperville, and the downdraft patterns that plague windward exposures on taller two- and three-flats.
We’re not a franchise. Level Two Chimney Co. is independently owned and operated under the Haven Standard, with background-checked technicians and materials sourced through our buying network from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. That keeps our prices honest and our parts in stock.
Our Chimney Repair Services in Chicago
Mortar Repointing
Chicago’s roughly 100 sub-freezing days per year destroy mortar joints faster than in drier inland markets. Lake Michigan moisture saturates the brick, freezes, expands, and blows out the pointing - especially on south and west exposures that get the worst of the westerlies. Repointing a typical Chicago bungalow chimney runs $1,200-$2,800. We grind out failed joints to proper depth, match the original mortar composition for thermal compatibility, and seal the crown and cap to protect the new work. Repointing without waterproofing fails in two or three winters here. We show you why on camera before we quote.
Spalling Brick Repair
Spalling - the flaking and crumbling of brick faces - is freeze-thaw damage accelerated by Chicago’s lake-moisture environment. In Bridgeport, Clearing, and Archer Heights, we regularly find spalling caused by a hidden culprit: original coal flues converted to gas without proper liners, letting acidic condensate attack the interior brick while lake moisture hits from outside. Surface patching hides the problem. We run the camera first, identify the moisture source, then rebuild with matching brick or install a proper insulated liner to stop the cycle. Spalling repair ranges $800-$2,500; if the structural course is compromised, partial rebuild may be necessary.
Chimney Waterproofing
Waterproofing is not optional in Chicago. The lake effect keeps masonry at elevated moisture content for months, and without a breathable silane/siloxane treatment, repointed chimneys absorb water and fail prematurely. We apply treatments from reputable manufacturers, never hardware-store sealers that trap moisture inside. Waterproofing a standard bungalow chimney runs $400-$900 and extends mortar life by years. We document before-and-after absorption readings with every application.
Flashing Repair
Chicago’s wind-driven rain and ice damming at roof penetrations chew through flashing faster than in sheltered suburban locations. Step flashing, counter-flashing, and cricket installations on bungalows and two-flats require precise integration with existing roofing. We use copper or galvanized steel matched to the application, never caulk-over jobs that last one season. Flashing repair typically runs $350-$1,200 depending on roof pitch, access, and whether the cricket needs rebuilding.
Chimney Rebuilding
When spalling, settling, or structural compromise exceeds repair scope, we rebuild. Chicago’s bungalow belt chimneys often need partial rebuild from the roofline up, or full rebuild when the foundation course has shifted. A full rebuild on a standard Chicago bungalow stack ranges $3,500-$8,000, including demolition, matching brick procurement, proper liner sizing to the appliance, and full documentation. We never recommend rebuild without camera evidence you can see - Clause 4 requires it, and our 38,000-job record proves we’ve stuck to that.
Tuckpointing
Tuckpointing in Chicago addresses the aesthetic and structural integrity of historic masonry. On greystones and vintage two-flats in neighborhoods like Hyde Park and Oak Park, we match original mortar color and profile to maintain architectural character while restoring weather resistance. Tuckpointing runs $1,500-$3,500 for a typical Chicago stack, with heritage-color matching included.

AfterTrusted Brands We Service in Chicago
We stock liners, caps, dampers, and repair materials from DuraFlex, HeatShield, and Olympia Chimney through our Haven buying network, with Gelco components available for specialized applications. That means Chicago customers don’t wait weeks for parts - most repairs proceed on schedule without special-order delays. HeatShield’s cerfractory foam resurfacing system, for instance, lets us restore deteriorated clay liners in Chicago’s coal-era chimneys without full replacement when the camera shows suitable substrate. We specify the right material for the condition we documented, not the most expensive option.
Common Chimney Repair Problems We See in Chicago Homes
- Unlined coal-era flues with improper gas conversion. In Bridgeport, Clearing, and Archer Heights, we routinely find a 9×13-inch rectangular coal flue with no clay liner and only a loose B-vent or flex pipe dropped down the center. Cold outside air hits the flue walls, condensate forms, and the mortar and brick spall from freeze-thaw within a few seasons. The damage is hidden until the camera goes down.
- Two- and three-flat shared stacks with untraced flues. Multiple appliances vent into one chimney chase across separate units. Without camera tracing of each flue, cross-contamination or missed blockages stay hidden behind a basic visual check. We’ve found dead birds blocking one flue while the adjacent flue appeared clear from the top.
- Lake moisture plus freeze-thaw destroying crowns and mortar. Chicago’s ~100 sub-freezing days crack clay liner sections and blow out joints faster than in drier markets. Crown cracks let water straight to the flue; without waterproofing and cap repair, repointing alone fails quickly.
- Negative-pressure downdraft on windward exposures. Lake Michigan’s prevailing westerly and northerly winds create downdraft complaints on taller two- and three-flat buildings that technicians in Naperville or Joliet rarely see. The fix isn’t always a taller cap - sometimes it’s proper liner sizing and combustion air correction.

FAQs - Chimney Repair in Chicago
Because most Chicago bungalows have original coal-era flues that were later converted to gas without proper relining, and the damage is inside the wall where a flashlight can’t reach. Our Chimney Repair team runs an NFPA 211 Level 2 camera inspection on every Chicago job to document liner condition, mortar integrity, and creosote class before quoting. In Bridgeport, we once found a 9×13-inch unlined coal flue with a loose B-vent and a 3-inch open gap - invisible from the roof or fireplace. Clause 4 of the Haven Standard requires this photo record; we’ve done it on all 38,000 jobs since 2009. Call (708) 234-1174 to schedule - estimates are free.
Lake Michigan moisture saturates the brick, then Chicago’s roughly 100 annual sub-freezing days drive repeated freeze-thaw expansion that spalls faces and blows out joints. The damage accelerates when an unlined or improperly converted flue lets acidic condensate attack interior surfaces simultaneously. Waterproofing, proper liner installation, and timely repointing stop the cycle. We show you the moisture source on camera before recommending any repair. Call (708) 234-1174 for a free estimate.
Shared stacks require precise flue tracing to identify which appliance vents where. Without a camera, a technician can clean or repair the wrong flue, miss a blockage in another, or allow cross-contamination between units. Chicago’s two-flats and three-flats frequently have this configuration, and we’ve found dead obstructions in one flue while the adjacent appeared clear from a basic visual check. We trace every flue independently and document each with photos. Call (708) 234-1174 to book a Level 2 inspection.
Signs include persistent condensation stains on interior chimney walls, poor draft, sulfur or rotten-egg odors, and visible corrosion of the metal vent connector. But the only certain method is a camera inspection. In Chicago’s bungalow belt, we regularly find flex pipes or B-vents running through oversized, unlined masonry chases - a configuration that destroys chimneys from both directions. We document what we find, explain it in plain terms, and quote only what’s necessary. Call (708) 234-1174 for a camera inspection.
Yes. Lake Michigan’s prevailing westerly and northerly winds create negative-pressure downdraft conditions on windward exposures of taller buildings, particularly two- and three-flats. This shows up as smoke rollout, pilot light failure, or cold air dumping down the flue. Technicians in Naperville or Joliet encounter it far less often. The solution may involve proper liner sizing, combustion air correction, or cap design - but only after camera diagnosis confirms the flue is clear and properly configured. Call (708) 234-1174 to schedule.
