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.

Why Emberly Chimney Cleaners Is Chicago’s Preferred Chimney Cap & Crown Company
We inspect chimneys the way a good home inspector checks a foundation: with a camera, not a flashlight. Since 2009, every Chimney Cap & Crown job we’ve done in Chicago has started with an NFPA 211 Level 2 camera scan, and the footage stays with you. That’s Clause 4 of the Haven Standard, and it’s been our default since before regulators or insurers thought to ask for it. A cap replacement on a two-flat in Logan Square or a crown repair on a bungalow in Bridgeport isn’t guesswork here. You see what we see.

That’s stamped on the job paperwork under the Haven Standard, not hidden in fine print.
Our Chimney Cap & Crown Services in Chicago
Cap Installation
A new cap on a Chicago chimney has to do two jobs: keep rain and snow out of the flue, and stay put through a winter that can throw a dozen freeze-thaw cycles at it in a single month. We install galvanized, stainless, and copper caps sized to your exact flue dimensions, not whatever’s on the truck. For bungalows in neighborhoods like Portage Park or Jefferson Park where the flue was built for coal and never relined, we’ll often recommend a cap with a larger mesh opening and tighter screen to handle condensation without trapping it.
Cap Replacement
We replace rusted, dented, or missing caps throughout Chicago. A cap that’s corroded through at the seams isn’t protecting anything, and on the Northwest Side especially, we see Famco caps that have been eaten from the inside by acidic condensate pooling in oversized tile flues. We pull the old cap, camera the flue below it, and show you footage of what the cap was actually protecting, or failing to protect. Then we install the replacement and document it with photos.
Crown Repair
Chimney crowns on Chicago’s 1910s and 1920s brick chimneys spall badly. Lake Michigan keeps winter temperatures hovering near freezing, so water freezes, thaws, and re-freezes inside the crown’s mortar joints dozens of times per season. That’s why we see more spalled crowns here than in almost any other market we serve. We repair crowns with a proper Portland-based crown mix, not the same mortar used on the brick face, and we pour it with a slight slope so water sheds away from the flue instead of pooling against it.
Crown Coating
When a crown is structurally intact but starting to crack, a flexible crown coating can buy years of service for around half the cost of a rebuild. We use CrownCoat and similar brush-on sealants that flex with Chicago’s thermal swings without separating. A crown coating in Chicago works best on crowns that aren’t already spalling, which is why we camera the crown surface and tap for voids before we recommend it. If the crown is too far gone, we’ll tell you that plainly and show you why.
Multi-Flue Cap
Two-flats and three-flats in neighborhoods like Avondale, Pilsen, and Bridgeport share a single exterior chimney, but each unit vents through its own flue. A multi-flue cap covers all of them under one frame while keeping each flue independently vented. We custom-fabricate multi-flue caps when stock sizes don’t fit, and we always camera each flue separately before measuring. One flue may vent an active furnace while the one next to it was abandoned decades ago. The abandoned flue is the one that’s been letting water in and cracking mortar across the whole chase wall.
Custom Cap
Old Chicago chimneys weren’t built to modern flue dimensions. A custom cap is often the only option for a 1920s bungalow with a 9×13 clay tile flue or a three-flat with an irregular chase. We measure, fabricate, and install custom caps in copper, stainless, or galvanized steel, and we match the cap to the flue size exactly. In Portage Park, we pulled a rusted Famco cap from a bungalow’s abandoned furnace flue and found the chimney crown spalling across a shared chase wall that also vented the living-room fireplace. Camera footage showed the adjacent tile flue had cracked from fifty years of acidic condensate pooling against it, so we sealed the crown, installed a Copperfield multi-flue cap, and the homeowner could finally see why the brick face had been flaking.

BeforeAfterTrusted Brands We Service in Chicago
We install and service caps and crown materials from Famco and Copperfield, and we stock the common sizes Chicago homes actually need, so there’s no two-week wait for a part shipped from a warehouse. When a flue has already started deteriorating from condensate, we sometimes pair a cap replacement with a DuraFlex liner or a HeatShield resurfacing treatment. We don’t push either one unless the camera footage supports it. Materials come through Haven’s buying network specifically to keep Chicago prices honest, and you’ll see brand names and part numbers on the written estimate before anything gets ordered.
Common Chimney Cap & Crown Problems We See in Chicago Homes
- Spalled crowns from freeze-thaw cycling. Chicago’s near-freezing winter temperatures, moderated by Lake Michigan, force water into crown mortar joints repeatedly all season. The crown face flakes off in chunks, leaving the flue opening exposed.
- Corroded caps on gas-converted chimneys. Bungalows built between 1910 and 1950 were designed for coal. When converted to gas without relining, the oversized tile flue pools acidic condensate that eats through the cap from below, especially on the Northwest and Southwest sides.
- Shared chase walls with one abandoned flue. Two-flats and three-flats often have a single chimney cap covering four flues, and one of those flues was abandoned decades ago. Water enters through the abandoned flue, soaks the shared chase wall, and cracks mortar joints across all the active flues.
- Improperly sized replacement caps. A cap that doesn’t match the flue dimensions traps moisture instead of shedding it. We see this constantly on 1920s chimneys where a previous contractor installed whatever cap was on the shelf, not one sized to the flue.
Pricing for Chimney Cap & Crown in Chicago, IL
A chimney cap replacement in Chicago runs $425-$650 for a standard single-flue galvanized or stainless cap, installed. A multi-flue cap on a two-flat or three-flat runs $750-$1,150 depending on chase width and flue count. Crown repair with grinding and repointing runs $425-$750; a full crown rebuild, which means removing the old crown and pouring new concrete with proper slope, runs $750-$1,150. Custom copper caps for older bungalows start around $650 and go up from there. The factors that move the price in Chicago are flue size, access (some Near North Side rooflines are steep and require additional fall protection), and whether the crown needs a coating or a full rebuild. Every estimate is written, scoped, and priced before anyone starts. Call (980) 580-8641 for an exact quote.

FAQs - Chimney Cap & Crown in Chicago
Lake Michigan keeps Chicago temperatures hovering near freezing for weeks at a time, so water trapped in crown mortar freezes and thaws dozens of times each winter instead of staying frozen. Each cycle forces the joints apart a little more, and after 80 or 100 years, the crown face starts flaking off in chunks. Suburbs further inland stay colder and freeze more deeply, so they see fewer of these partial-thaw cycles per season. Call (980) 580-8641 for a camera look at your crown before the next freeze arrives.
Yes, but you likely need a cap sized and vented for a gas appliance, not a generic cap that traps condensation. Gas exhaust is cooler than coal exhaust, so it condenses inside an oversized tile flue, and that acidic condensate corrodes whatever cap is sitting on top. On Chicago’s bungalow belt, this is one of the most common reasons a cap rusts out in five years instead of twenty. We camera the flue first, measure it, and spec a cap that handles the appliance you actually have. Call (980) 580-8641 for a written estimate.
We install a multi-flue cap with a separate screened opening for each flue, custom-fabricated when stock sizes don’t match the chase width. Each flue is camera-scanned independently before we measure, because one flue may be active while an adjacent one is abandoned. The abandoned flue is often the source of the water problem, and covering all of them under one properly sized cap stops that. Call (980) 580-8641 and we’ll schedule a Level 2 camera scan of every flue on the stack.
Sometimes, but only if the water entering the chimney is the cause of the brick flaking. A missing cap or a cracked crown lets water into the flue, and that water works outward through the brick face over time. If the flaking is from spalling on the crown itself or from a failed wash, a cap alone won’t fix it. We camera the crown, the flue interior, and the brick face, then show you exactly where the water is getting in. Call (980) 580-8641 for a free estimate with a documented photo report.
Because the cap is rarely the whole problem. A 1920s bungalow chimney in Chicago was built for coal, converted to gas, and has been through roughly a hundred freeze-thaw winters. The flue liner may be cracked, the crown may be spalled, or the mortar joints may be shedding water into the chase wall. Replacing the cap without looking underneath is like putting a new roof on a house with a failing foundation. Our NFPA 211 Level 2 camera scan documents everything before you spend a dollar. Call (980) 580-8641.
