We’ve been working in Corona’s 11368 ZIP code and the surrounding blocks for over four decades. We know the 1920s-1940s attached brick rowhouses along Roosevelt Avenue, the semi-detached two-families near Flushing Meadows-Corona Park, and the converted multi-unit buildings that line streets like 108th and 111th. These chimneys weren’t built for modern heating equipment, and they weren’t built to be shared by three apartments with three separate landlords. That mismatch is where most of the trouble starts.

Our Chimney Cap & Crown Services in Corona
Multi-Flue Cap Installation
Corona’s rowhouses demand multi-flue caps. A single chimney stack between attached units often serves two, three, or four separate flues, each venting a different appliance for a different apartment. A standard single-flue cap won’t seal that chase top. It leaves gaps where water pours in, where squirrels nest, where embers escape. We measure the full chase top and fabricate a custom multi-flue cap, usually from Olympia Chimney stainless steel or a Copperfield galvanized model when budget is tight. The cap covers every flue individually with its own screened hood, while the single skirt seals the entire crown surface. On a 1936 attached brick row house on 108th Street, we found a crumbling crown that had let water seep into three flues serving separate apartments. We installed a custom multi-flue stainless steel cap from Olympia Chimney and applied a HeatShield crown coating to seal the old masonry, stopping the leaks and bringing the shared stack into DOB compliance.
Crown Repair
The original concrete crowns on Corona’s 1920s-1940s chimneys were poured without reinforcement, without overhang, and often without proper slope to shed water. After a century of Queens freeze-thaw cycling, they’re cracked, spalled, or separated from the flue tiles entirely. We cut out the damaged concrete, form a new crown with proper drip edge and slope, and pour a reinforced mix that sheds water instead of trapping it. For rowhouse chimneys, this is critical. A cracked crown on one unit directs water into shared flues, and that water finds its way into adjacent apartments. We’ve seen it trigger violations across an entire row.
Crown Coating
When the crown’s damage is surface-level, crown coating is a practical alternative to full replacement. We use HeatShield CrownCoat, a flexible refractory compound that bridges hairline cracks and seals porous concrete against further water intrusion. It won’t save a crown that’s structurally failed, but for a crown that’s simply weathered and beginning to map with fine cracks, it’s a sound repair that extends service life by years. In Corona, where many landlords have deferred maintenance across decades of informal unit conversions, we often find crowns that are candidates for coating if we catch them before the next hard freeze.
Cap Replacement
Corona chimneys wear mismatched caps. Successive landlords, each facing a leak in their unit, have slapped on whatever cap was cheapest at the time. The result is a chase top crowded with ill-fitting hardware, gaps between caps, and straps that don’t anchor to anything solid. We remove the whole assembly, assess the crown beneath, and install a proper cap or multi-flue system sized for the actual flue count and output. We carry standard sizes for common flue diameters, so most replacements are done in one visit.

Trusted Brands We Service in Corona
We don’t use builder-grade substitutes. Our trucks stock caps, crowns, and coating materials from Famco, Copperfield, and Olympia Chimney, with DuraFlex liner components when relining is part of the job. For Corona customers, this means no waiting for parts to ship. We measure, we cut or select from stock, and we install. The brands we use are the same ones specified by NYC DOB inspectors and major property management companies. That’s not an accident. A cap that fails in two years because the mesh was too light or the skirt was too short is a cap we have to warranty. We prefer to do it once.
Common Chimney Cap & Crown Problems We See in Corona Homes
- Freeze-thaw destruction of original crowns. Queens winters fluctuate around freezing for weeks, and water trapped in Corona’s century-old concrete crowns expands and contracts until the surface spalls and cracks. Annual inspection catches this before the crown fails completely.
- Mismatched caps from piecemeal landlord repairs. Successive owners of Corona’s subdivided rowhouses have installed caps without sealing the chase top, creating gaps that admit birds, squirrels, and rainwater into multi-flue systems. We remove the clutter and install a single proper assembly.
- Carbon monoxide risk from cracked crowns in shared stacks. Because Corona’s attached rowhouses share masonry chimney walls, a cracked crown or failed flue liner in one unit can vent exhaust into a neighboring apartment. This is not theoretical. We find it on inspection calls several times a year in 11368.
- DOB violations from abandoned or offset flue sections. Informal renovations over generations have left Corona chimney interiors with mixed-condition flues, open thimbles, and missing liner sections. These surface as open violations on NYC Department of Buildings reports, and the cap or crown repair is often the first step toward full compliance.

What moves the number? Height and access are the main variables. A three-story rowhouse with a steep roof pitch takes longer and requires more setup than a two-story semi-detached. The condition of the existing crown matters too. If we’re installing a cap on sound masonry, it’s straightforward. If we have to rebuild the crown first, that adds labor and material. We give you the full price before we start. The number on the estimate is the number on the invoice. Call (855) 950-3861 for an exact quote. Estimates are free.

FAQs - Chimney Cap & Crown in Corona
Yes. If your chimney has two or more flues opening into the same chase top, a single-flue cap will leave the other flue exposed and create gaps where water and debris enter. We measure the full chase top and install a custom multi-flue cap that covers each flue individually while sealing the entire crown surface. Call (855) 950-3861 and we’ll check your flue count on inspection.
Every year, before winter. Queens freeze-thaw cycling degrades unreinforced concrete crowns aggressively, and Corona’s century-old chimneys are particularly vulnerable. An annual Level-2 camera inspection with photos lets you catch crown damage before it fails and starts leaking into shared flues. Call (855) 950-3861 to schedule.
No. Crown coating bridges hairline cracks and seals porous surfaces, but it cannot restore structural integrity to a crown that is spalled, separated from flue tiles, or crumbling. For that, we remove and repour. We assess the crown during inspection and tell you straight whether coating or replacement is the right call. Call (855) 950-3861 for a free evaluation.
Successive landlords in subdivided rowhouses have made piecemeal repairs, adding mismatched caps, offset tiles, or abandoned flue sections without proper documentation or sealing. These informal renovations produce mixed-condition chimney interiors that routinely fail NYC Department of Buildings inspection. The violation is usually the symptom; the underlying problem is an unsealed chase top and compromised flue system. We repair the chimney to code and provide documentation for DOB compliance. Call (855) 950-3861 to discuss your violation notice.
A properly fitted multi-flue cap helps, but it is only one part of the system. The cap prevents water and debris intrusion and contains sparks, but preventing carbon monoxide migration between units requires intact flue liners, properly sealed joints, and correct sizing for each appliance. In Corona’s shared masonry stacks, we often find that cap repair must be paired with relining to fully address the risk. Our inspection determines the complete picture. Call (855) 950-3861 for an assessment.
