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 runs $325 to $1,900 for most crown, flashing, and mortar jobs, and the majority of them are caused by water, not fire. Freeze-thaw cycles chew through mortar and crack chimney crowns on this city’s older brick buildings, which is why we see so many leak-driven calls from Lake View to Beverly. You won’t get a foggy estimate from us. You’ll get a written price before any tool comes off the truck, plus a full-year written guarantee on every repair. If you’re seeing water stains, crumbling brick, or a loose chimney cap, call (830) 251-4560 and we’ll send a background-checked technician to take a look.

Why Flint Chimney Sweep Is Chicago’s Preferred Chimney Repair Company
We’ve been in business since 2002 as part of the Garrison Partners family, and the reason Chicago homeowners keep calling us back is simple: we put everything in writing. The price, the scope, the guarantee. Our Chimney Repair crews work under the Garrison Standard, which means a written price before work starts, a background-checked technician on every call, and a one-year written guarantee on every repair we make. If a covered repair fails within that year, we return at no charge. That’s not a marketing line. It’s the document you receive before you approve anything.
Chicago’s housing stock runs old. We work on greystones in Lake View, bungalows in Portage Park, two-flats in Humboldt Park, and full brick houses down near Beverly and Bridgeport. Each of those buildings has its own chimney construction quirks, and our techs know them because they work them every week. When a Chicago homeowner calls us about a leak or a crack, we don’t guess. We run a camera inspection, take photos, and walk you through what we found before we ever ask for a decision.
Chimney Flashing Repair in Chicago
Chimney flashing repair in Chicago is the most common repair we perform, and it’s almost always triggered by the city’s weather. Flashing is the metal barrier where the roof meets the chimney stack. Chicago’s freeze-thaw cycles expand and contract that metal and the surrounding mortar, and over three or four winters the seams open up. Water gets in. You see a brown stain on the ceiling near the chimney and assume the worst. In most cases, the fix is replacing the flashing and resealing the joint, which runs $450 to $1,100 on a typical Chicago roof pitch.
When Flashing Fails
The tell is usually a ceiling stain or damp drywall beside the chimney, not directly under it. Water travels. A flashing leak near the roofline can show up ten feet away. If you call us for any leak, we inspect the flashing first because in Chicago it’s the most likely culprit. No charge for the inspection.
Materials That Last
We use Olympia Chimney flashing materials on most Chicago jobs because they hold up against the lakefront weather. For older homes with non-standard roof pitches, we’ll fabricate the flashing on-site rather than forcing a prefab piece that won’t seat correctly. A tight flashing seam matters more than the material brand behind it.
Chimney Crown Repair in Chicago
Chimney crown repair in Chicago typically runs $600 to $1,400 for a full rebuild. The crown is the concrete or mortar cap that sits on top of the masonry stack, and it’s the chimney’s first line of defense against rain and snow. Chicago’s freeze-thaw cycles crack crowns faster than almost any city we work in. Water pools in those cracks, freezes, expands, and the crack deepens. Eventually the crown spalls, which means the surface starts flaking and breaking apart in chunks. Left alone, that water eats into the brick face below and you’re looking at a much bigger job.
Signs Your Crown Is Compromised
If you see pieces of crown material on your roof or at the base of the chimney, that’s spalling. If you notice water stains inside the firebox or a musty smell after rain, that’s often crown failure. A visual inspection from the roof tells us quickly whether a minor seal or a full rebuild is needed. Photos come with it either way.
Rebuild Versus Patching
Small hairline cracks can sometimes be sealed with a Gelco crown coat, which runs at the lower end of that $600 to $1,400 range. A crown that’s already spalled and losing material usually needs full demolition and a Gelco crown mix rebuild. We make that call with you based on the camera photos, and you approve the written price before we touch anything.
Trusted Brands We Service in Chicago
We specify materials by what the job needs, not by what earns us the biggest margin. That’s why our Chicago repair trucks carry Gelco crown mixes, HeatShield for smoke chamber and flue liner restoration, and Olympia Chimney flashing products. We also work with Famco caps and dampers when a repair calls for component replacement. When you get your written estimate, it names the exact product going onto your chimney. If you want to look it up before you approve, good. That’s the point.
Common Chimney Repair Problems We See in Chicago Homes
- Spalling crowns and open flashing seams. Older Chicago brick chimneys take a beating from snow, ice, and lake-effect moisture. The crown cracks, the flashing loosens, and water becomes the repair trigger on the vast majority of our calls.
- Compromised flue liners in furnace-vented chimneys. A lot of Chicago homes don’t have working fireplaces. Their chimney vents the furnace or water heater instead. A cracked flue liner there isn’t a fireplace problem, it’s a carbon monoxide problem, and a camera inspection is the only way to see it clearly.
- Third-degree creosote glaze in the smoke chamber. Sweeps who skip camera work miss this. A brush can’t remove glazed creosote. It typically requires a HeatShield treatment or chemical application before any liner or masonry repair can be completed properly.
- Delayed repairs on two- and three-flats. When the chimney serves a furnace flue in a building with multiple units, no one person feels the urgency. Water keeps working, the flue liner keeps degrading, and by the time anyone looks, the repair is bigger than it had to be.

FAQs About Chimney Repair in Chicago
Most Chicago chimneys need some repair work every 5 to 8 years, and the schedule is driven by water exposure more than fireplace use. Flashing seams and crowns fail first because they’re the most exposed to freeze-thaw cycling. An annual Chimney Inspection - Chicago catches small problems before they become liners and masonry rebuilds. Call (830) 251-4560 to book an inspection and we’ll tell you honestly what needs work now and what can wait.
We inspect first, with a camera and photos. You see everything we see. Then you get a written price with the exact scope and materials named. You approve it, we do the work, and the repair comes with a 365-day written guarantee. If a covered repair fails within that year, we come back and fix it at no charge. No arguing, no revisiting the price.
Yes, and in Chicago that’s exactly what we do most of the time. A cracked or spalled crown rarely means the whole chimney needs rebuilding. We’ll either seal it with a Gelco crown coat or rebuild the crown itself with a fresh Gelco mix, which runs $600 to $1,400. The masonry below often just needs repointing, not demolition.
You don’t know until someone actually looks at the roof transition and the chimney top. But the pattern is telling. Ceiling stains beside the chimney usually mean flashing. Water inside the firebox or smoke chamber usually means crown. We confirm either one with a camera and photos, then give you a written price on the exact fix.
No, and we won’t sell you on it either. Chimney repair in a freeze-thaw city like Chicago needs to be scheduled with the right materials and the right weather window. Rushing a crown rebuild in the wrong conditions is how you get a leak next spring. We schedule for the soonest date that lets us do the job right, and you still get the same written guarantee.
