We’ve been working on Berwyn chimneys since 2014. The brick bungalows along Lombard Avenue, the two-flats near Cermak Road, the solid masonry homes south of Roosevelt Road - we’ve capped and crowned them all. These houses were built with coal-fired furnaces in mind, and their chimneys tell that story in every course of brick. Our Chimney Cap & Crown team knows how to protect that legacy without pretending it’s a new construction job.

Our Chimney Cap & Crown Services in Berwyn
Crown Repair
Crown repair is the most common chimney cap and crown service we perform in Berwyn. The original lime mortar crowns on 1920s bungalows simply weren’t formulated to survive decades of Chicago freeze-thaw cycling. We remove the deteriorated material, pour a new reinforced crown with proper slope and overhang, and seal it to shed water away from the flue. On a 1920s brick bungalow on Lombard Avenue, we found the original terra cotta crown crumbling after a harsh winter. We replaced it with a DuraFlex crown and installed a multi-flue copper cap from Copperfield to prevent rain from entering the oversized flue serving only a water heater. Most Berwyn crown repairs run $680-$1,250.
Crown Coating
When the crown is cracked but structurally sound, crown coating buys years of protection without the cost of full replacement. We use HeatShield crown coating products, applied after proper surface prep - wire brushing, crack chasing, and moisture testing. In Berwyn’s dense bungalow neighborhoods, century-old terra cotta flue liners are often cracked or offset from freeze-thaw cycles, making crowns and caps critical to prevent water entry that accelerates liner failure. Crown coating typically costs $280-$520 in Berwyn.
Cap Installation & Replacement
Missing or undersized caps are a plague on Berwyn’s orphaned chimneys. A proper cap keeps rain, squirrels, and nesting material out of a flue that may already have compromised terra cotta. We size caps to the actual flue opening, not the chimney top, and we use Gelco and Olympia Chimney caps with stainless steel mesh that won’t rust shut. Standard single-flue cap installation in Berwyn runs $180-$340. Multi-flue caps for larger chimneys range $340-$620.
Multi-Flue Cap
Many Berwyn two-flats and larger bungalows have multiple flues sharing one chimney top. A multi-flue cap covers the entire chimney crown, protecting all flues and the crown itself. This is especially important on orphaned chimneys where one flue is abandoned and the other serves only a water heater - the abandoned flue becomes a water funnel without proper coverage. Multi-flue cap installation in Berwyn typically costs $480-$850 depending on chimney dimensions and access.
Custom Cap
Some Berwyn chimneys - particularly on modified bungalows with added flues or unusual crown profiles - need custom fabrication. We measure, specify, and install custom caps from Copperfield when stock sizes won’t seal properly. Custom cap work in Berwyn starts around $620 and is completed with the same single-visit efficiency as our standard installations.

Trusted Brands We Service in Berwyn
We don’t use builder-grade substitutes on Berwyn chimneys. Our trucks carry DuraFlex crown materials, HeatShield coating systems, and Gelco and Olympia Chimney caps - professional-grade products sized for the repair, not the budget. Because we stock these brands locally, most Berwyn homeowners don’t wait for parts. The cap or crown goes on the same day we diagnose it. That’s how most jobs get done in a single visit, and that’s how we keep our schedule honest.
Common Chimney Cap & Crown Problems We See in Berwyn Homes
- Lime mortar crown joints spall after repeated freeze-thaw. Berwyn routinely crosses the 32°F threshold dozens of times each winter. That cycling opens hairline cracks in original crowns, lets water penetrate, and by spring the surface is crumbling. We inspect for this damage every April and May.
- Multi-flue caps are undersized or missing on orphaned chimneys. With so many Berwyn bungalows now running high-efficiency furnaces that exit through PVC sidewall vents, the old masonry chimney is left serving only a standard-efficiency water heater in a flue two or three times larger than needed. Rain enters the oversized flue, saturates cracked terra cotta, and accelerates liner failure.
- Caps installed without proper sealant around terra cotta liners create paths for water. We’ve removed plenty of “handyman specials” in Berwyn where a cap was screwed to brick without sealing the liner interface. Water follows the path of least resistance - straight down into the flue.
- Original crowns never had expansion joints. The solid-pour concrete crowns on post-war Berwyn two-flats crack predictably as the chimney settles and thermal cycles. We cut control joints in new crowns to prevent the random cracking that doomed the originals.

FAQs - Chimney Cap & Crown in Berwyn
Yes - and you likely need a properly sized cap for an orphaned flue, not just any cap off the shelf. The old flue now serves only your water heater (if anything), and its oversized diameter creates cold stack temperatures that prevent proper draft. Rain entering an unlined or cracked flue accelerates deterioration and can force carbon monoxide into your utility room during backdraft conditions. We assess orphaned flues with our Level-2 camera inspection, document the liner condition with photos, and specify a cap that seals properly to the terra cotta. Call (888) 289-6055 for a free estimate - we’ll show you exactly what your flue looks like inside.
Berwyn’s aggressive freeze-thaw cycle attacks the aged lime mortar and porous concrete in original crowns. Your chimney likely crosses the freezing threshold dozens of times each winter, and water trapped in micro-cracks expands with each cycle. By spring, the surface is spalling. Original crowns on 1910-1945 construction also lacked modern air-entrainment in their concrete mix, making them especially vulnerable. We address this with proper crown slope, overhang, and expansion joints in new construction - or with flexible crown coating when the structure is sound. Call (888) 289-6055 to schedule a post-winter inspection.
We don’t recommend it. Berwyn’s original chimneys have terra cotta flue liners that are often cracked, offset, or deteriorated at the top - conditions you can’t assess safely from a ladder. A cap installed over damaged liner without proper sealant traps moisture or creates new water paths. Worse, many Berwyn chimneys have unstable brick at the top course from years of water infiltration. Our technicians carry the proper ladder equipment for bungalow rooflines and know how to assess structural integrity before capping. The cost of professional installation includes that assessment, and it’s backed by our 90-Day Done Right Promise. Call (888) 289-6055 - estimates are free.
An orphaned flue is a chimney flue left serving only a small appliance - typically a water heater - after its original furnace was removed or converted to direct-vent. In Berwyn, this is the defining chimney condition: thousands of bungalows have high-efficiency furnaces venting through PVC sidewalls, leaving the old masonry chimney with just a water heater in a flue designed for a coal boiler. The flue is too large, stays too cold, and drafts poorly. Carbon monoxide spillage is a documented hazard. Your cap must be sized and sealed to this reduced duty, and the flue may need downsizing or relining. We evaluate orphaned flues with camera inspection and specify caps that don’t mask underlying hazards. Call (888) 289-6055 - we’ll explain what your chimney actually needs.
Possibly. Many Berwyn two-flats have multiple flues of different diameters, offset from each other, or irregular crown profiles that won’t accept stock multi-flue caps. We measure on site and fabricate custom caps from Copperfield when needed. The alternative - forcing a stock cap to fit - leaves gaps that let water and animals in. Custom caps in Berwyn start around $620 and are typically installed same-day once fabricated. Call (888) 289-6055 and we’ll tell you whether your chimney needs custom work after a quick inspection.
