Fast, Reliable Chimney Cap & Crown Across Evanston
Chimney cap and crown repair in Evanston typically runs $280-$650 for most residential jobs, with same-day service available throughout the city when you call (888) 289-6055. We’ve been driving to Evanston since 2014, and we know the difference between a quick cap swap on a 1990s Colonial in the west-end 60203 zip and a full crown rebuild on a pre-war masonry stack in the lakefront 60201 neighborhoods.
Our Chimney Cap & Crown team carries Gelco and Olympia Chimney caps in common sizes on every truck, plus the tools to fabricate custom copper caps for the decorative Edwardian chimneys you’ll find along Sheridan Road and in the northeast Evanston historic districts. Most calls from Evanston reach us within 20 minutes, and we schedule appointments with a two-hour arrival window, not an all-day wait.
The lake-effect moisture here is real, and it is destructive. Sitting directly on Lake Michigan, Evanston’s northeast winds saturate masonry crowns and caps far more aggressively than inland suburbs like Skokie or Des Plaines. We’ve replaced caps in Wilmette that looked ten years older than identical caps installed the same year in West Ridge, solely because of that sustained lake exposure. If your chimney faces east or northeast, you’re living with conditions that inland sweeps rarely see.
Why Hearthstone Chimney Co. of Chicago Is Evanston’s Preferred Chimney Cap & Crown Company
We’ve worked on chimneys in every Evanston neighborhood, from the Victorian-era homes near the university in 60201 to the brick two-flats along Dempster Street in 60202 and the mid-century builds in the southwest 60203 pocket. That familiarity matters when you’re diagnosing draft problems in a shared chimney or sourcing a cap that fits a non-standard flue opening from 1923.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If the crown has minor spalling, we’ll tell you. If the flue is unlined and converting that gas insert created a carbon monoxide pathway, we’ll show you the image and explain exactly what it means for your house.
Calls are answered by a live person, 24 hours a day, 7 days a week. Not a callback queue, not an app. When an Evanston homeowner calls at 7 a.m. because last night’s storm tore the cap off and water is now hitting the firebox, someone picks up and schedules the repair.
Our 90-Day Done Right Promise applies to every job in Evanston, in writing, with no arguing. If the cap leaks or the crown coating fails, we come back. We’ve been in business since 2014, and we plan to be answering this phone in 2054. That changes how you treat every customer.
Our Chimney Cap & Crown Services in Evanston
Cap Installation
New cap installation in Evanston runs $180-$340 for standard single-flue galvanized or stainless steel units, and $420-$780 for custom-fabricated copper caps on decorative chimneys. We size every cap to the flue opening, not the chimney top, because an oversized cap on a converted coal-era flue traps moisture and creates the exact downdraft problems we see in east-facing Evanston homes. Our trucks stock Gelco and Olympia Chimney caps in the four most common flue dimensions used in pre-1940 Evanston construction.
Cap Replacement
Most cap replacements in Evanston are not wear-and-tear. They’re corrosion failures from lake-effect moisture and salt spray, or detachment after the original installer used the wrong fasteners for masonry that experiences repeated freeze-thaw cycling. We remove the failed cap, inspect the flue tile and crown beneath it, and install the replacement with stainless steel fasteners and a proper storm collar. A cap replacement without inspecting what’s underneath is half a job. We don’t do half jobs.
Crown Repair
Crown repair is our most common Evanston service, and for specific reasons. The persistent northeast winds and high moisture off Lake Michigan drive accelerated freeze-thaw mortar spalling on already-aged chimney crowns. In the east-side lakefront neighborhoods along and near Sheridan Road, original mortar joints on the lake-facing exposure have eroded two to three times faster than the sheltered sides of the same chimney. This pattern is almost invisible from street level but obvious once our camera is in the flue. Crown repair typically runs $340-$580 for partial rebuilds with professional-grade crown coating, and $680-$1,200 for full crown demolition and pour.
Crown Coating
For crowns with minor cracking and surface spalling but sound structural integrity, we apply HeatShield crown coating, a flexible, waterproof membrane designed for masonry that breathes. In Evanston’s climate, this is often the right middle path between ignoring the problem and a full rebuild. The coating fills cracks up to 1/8 inch, sheds water, and flexes with thermal expansion. We warranty crown coating work for five years, and we document the before-and-after with photos you can see.
Multi-Flue Cap
Evanston’s density of two-flats and three-flats means shared chimneys serving multiple units are common. A multi-flue cap covers all flue openings with a single hooded structure, eliminating the gaps between individual caps where water and debris enter. We measure the full chimney top, fabricate or order the cap to fit, and install it with proper clearances for each flue. Multi-flue caps in Evanston typically run $520-$890 installed, depending on size and material. This is not a stock-item job for most chimney companies. We carry the measuring tools and fabrication contacts to do it right.
Custom Cap
The decorative Edwardian and Victorian chimneys in Evanston’s historic districts were not built to accept stock caps. A custom copper cap, fabricated to match the chimney’s profile and patina, protects the flue without destroying the architectural character. Custom caps start at $680 and range to $1,400 or more for complex multi-flue covers with decorative bands or finials. We template the chimney on-site, send the specs to our fabricator, and install within two weeks. The result is protection that looks like it belongs there, because it was made for there.

Trusted Brands We Service in Evanston

For Evanston customers, this means we stock common cap sizes and crown coating materials on every truck, so most jobs are completed in a single visit.

Common Chimney Cap & Crown Problems We See in Evanston Homes
- Corroded metal caps from prolonged lake-effect moisture and salt spray. Evanston’s position on Lake Michigan exposes east-facing chimneys to conditions that inland suburbs simply don’t experience. We’ve removed caps that rusted through in five years, not fifteen, because the original installer specified standard galvanized steel instead of marine-grade stainless or copper.
- Spalled crowns from freeze-thaw cycles on east-facing chimneys. The repeated wet-freeze-thaw cycles deteriorate mortar joints, chimney caps, and crowns at an accelerated rate. Once the crown surface cracks, water penetrates the interior brick, and the structural decay accelerates through every winter. We catch this early with camera inspection, before the repair becomes a rebuild.
- Improper cap sizing on shared multi-flue chimneys in two-flats and three-flats. A cap that is too small for the flue opening, or too large for the chimney top, creates downdraft issues and traps moisture between the cap and the flue. In Evanston’s older housing stock, original flue dimensions often don’t match modern stock sizes, and lazy installers make do. We measure and fit.
- Negative-pressure and downdraft conditions on east-facing chimneys. The lake exposure creates draft problems technicians on the inland side of the region rarely encounter. A properly sized and installed cap, with the right screening and hood geometry, corrects most of these issues without the cost of a full chimney rebuild.

FAQs - Chimney Cap & Crown in Evanston
The sustained northeast winds and high moisture off Lake Michigan saturate and corrode metal caps at roughly twice the rate seen in inland suburbs like Skokie or Des Plaines. Salt spray from winter road treatment and lake aerosol accelerates galvanic corrosion, while freeze-thaw cycling stresses fasteners and seams. If your chimney faces east or northeast, inspect the cap annually, not every five years. Call (888) 289-6055 to schedule a free inspection.
If your chimney serves more than one flue, a multi-flue cap is the correct solution. Individual caps leave gaps between flues where water, debris, and animals enter, and they often create downdraft conflicts in shared chimneys. We replaced a failing crown and installed a custom multi-flue cap on a shared chimney serving two units in a 1920s three-flat on Sherman Avenue near the lakefront. The original crown was spalled from freeze-thaw cycles, and both flues were unlined, requiring HeatShield relining to meet safety code. Multi-flue caps typically run $520-$890 installed. Call for an exact measurement at your property.
Look for visible cracks on the crown surface, pieces of mortar or concrete missing from the top edges, or water staining on the interior firebox or adjacent ceiling. The definitive check is a Level-2 camera inspection, which reveals hidden crown deterioration and flue damage not visible from the roof. In Evanston, we regularly see crown damage that appears minor from outside but has already allowed water to compromise the interior wythe. We document every inspection with photos and a plain-English verdict. Call (888) 289-6055 to book.
Yes. We template on-site and fabricate custom copper caps for the decorative Edwardian and Victorian chimneys common in Evanston’s historic districts, particularly in the 60201 neighborhoods near the university and along Sheridan Road. Custom caps start at $680 and protect the flue without compromising architectural character. The copper develops a natural patina that blends with aged masonry. Call for a template appointment and exact quote.
No. Evanston’s pre-1940 masonry chimneys, originally built for coal, often have unlined or cracked clay tile flues that create a carbon monoxide risk when converted to gas appliances without proper relining. The smaller flue gases from modern gas units cool too quickly in oversized coal-era chimneys, causing condensation that deteriorates mortar and allows CO to leak through gaps into living spaces. We inspect with camera and provide plain-English guidance on relining options, including HeatShield systems designed for this exact conversion scenario. This is not a DIY evaluation. Call (888) 289-6055 for a safety inspection.
