Robert Garcia, our owner and lead technician, has spent 17 years working on chimneys exactly like yours — the shared party-wall masonry flues running through Borough Park’s dense rows of two- and three-story brick homes. We’ve rebuilt crowns on 14th Avenue, installed multi-flue caps near 50th Street, and sealed deteriorated concrete on New Utrecht Avenue. That repetition matters. When you’ve seen the same failure patterns on the same building types dozens of times, you diagnose faster and fix it right the first time.
Why Apex Chimney Cleaning Greater New York Is Borough Park’s Preferred Chimney Cap & Crown Company
Our Chimney Cap & Crown team has built a reputation in Borough Park by showing up personally — Robert Garcia handles the work himself, not a rotating subcontractor crew. Homeowners here value accountability, especially when the repair involves a shared party-wall chimney that affects a neighbor’s property. With 1,096 verified reviews averaging 4.7 stars, we’ve earned the trust of New York City homeowners who research before they hire.
Response time to Borough Park is typically same-day or next-day for urgent calls — water actively entering through a cracked crown or a cap that’s blown off in high winds. We’re already working in Brooklyn regularly, so dispatching to 11219 doesn’t involve the scheduling delays you’d face with a company based in Nassau County or New Jersey.
Our local knowledge runs deeper than geography. We understand how Borough Park’s housing stock fails: the original cast-concrete crowns on these 80-year-old chimneys, the oil-to-gas conversions that changed flue dynamics, the basement apartment water heaters that add a third vent to a cap designed for two. That specificity saves time and prevents callbacks.
Our Chimney Cap & Crown Services in Borough Park
Crown Repair
Crown repair is our most frequent call in Borough Park, and for good reason. The original concrete crowns on 1920s–1940s row homes shear at the party-wall seam from decades of differential settling between attached structures, splitting the cap across two or three addresses simultaneously. This isn’t a simple patch job. We grind back the deteriorated concrete, rebuild the slope with proper drainage geometry, and seal the repair so the next January freeze-thaw cycle doesn’t reopen the crack. On a typical three-story brick row house near 48th Street or New Utrecht Avenue, crown repair runs $275–$550.
Crown Coating
Crown coating buys time for crowns that aren’t structurally failed yet but are porous and cracking. In Borough Park’s climate — fall rains followed by hard freezes that repeat weekly through January and February — an unsealed crown absorbs moisture that expands and spalls the concrete from within. We apply HeatShield CrownCoat, a flexible refractory sealant that bridges hairline cracks and sheds water without trapping vapor. A coating application on a standard row-home crown typically costs $180–$325 and should be refreshed every 5–7 years in this freeze-thaw environment. It’s preventive maintenance that avoids the $800–$1,500 cost of full crown reconstruction.
Multi-Flue Cap Installation
Multi-flue caps are essential on Borough Park’s chimneys, which often vent two or three appliances — a furnace, a water heater, and sometimes a second water heater for a basement apartment. The original caps from the oil-burning era rarely accommodate these additional flues. We install DuraFlex stainless multi-flue caps sized to cover all active vents with proper clearance, attached with masonry screws and counter-flashing that won’t lift in Brooklyn’s wind patterns. A properly fitted multi-flue cap on a Borough Park row home runs $450–$850 installed, depending on flue count and access complexity.
Cap Replacement
Single-flue cap replacement is straightforward when the crown beneath it is sound. But in Borough Park, we often find that a “simple” cap replacement reveals crown damage hidden underneath the old unit. We carry Gelco and Olympia Chimney caps in common sizes on our truck, so most replacements don’t require a second visit. Standard cap replacement with inspection of the underlying crown: $150–$300. If the crown needs repair before the new cap can be secured, we’ll show you the damage and quote the additional work before proceeding.

Trusted Brands We Service in Borough Park
We install professional-grade materials from brands that commercial chimney contractors trust: Gelco and Olympia Chimney for standard and custom caps, HeatShield for crown coating and refractory repair, and DuraFlex for stainless multi-flue caps and liner systems. We stock common cap sizes and crown-coating supplies locally, so Borough Park customers aren’t waiting two weeks for a special-order part while water continues entering their chimney. When a custom fabrication is needed — say, a copper cap for a landmarked property or an unusual flue spacing — we work with Copperfield and Famco for made-to-order solutions with reasonable turnaround.
Common Chimney Cap & Crown Problems We See in Borough Park Homes
- Party-wall crown shearing. The single cast-concrete slab spanning multiple flues in attached row homes cracks at the seam between properties, pulling away from two or three adjoining households’ flues at once. This creates a compound leak that requires coordinated multi-address crown repair — a scenario virtually unknown in detached housing elsewhere.
- Condensation damage behind converted gas flues. Undersized clay liners sized for oil produce chronic condensation; moisture trapped between the liner and cap freezes and spalls brick, opening gaps that admit raccoons, squirrels, and debris into the flue.
- Improperly seated multi-flue caps after gas conversions. Caps installed before modern gas conversions often don’t accommodate the extra vent from a basement apartment’s water heater, so the cap sits crooked, leaving a gap that admits rain directly onto the crown.
- Freeze-thaw spalling on century-old mortar. Brooklyn winters bring repeated freeze-thaw cycles that are especially damaging to already mortar-compromised crowns; moisture that infiltrates during fall rains expands in January cold snaps, accelerating joint failure that we frequently discover during annual cleanings.

What drives cost up? Multiple flues needing coverage, extensive concrete demolition and formwork, or the need to install a new liner before capping. What keeps it down? Catching crown damage early with coating rather than waiting for full reconstruction. Every estimate we provide is free, itemized, and delivered after Robert inspects your chimney in person — not a phone guess.

FAQs — Chimney Cap & Crown in Borough Park
We can repair the portion of the crown over your flues, but if the crack runs through the party-wall seam, the structural integrity of the entire slab is compromised and the repair will fail. We always inspect the full crown and recommend coordinating with your neighbor when the damage spans both properties — it’s more cost-effective to fix it once than to return twice. Call (866) 884-9512 and we’ll assess the seam condition during your free estimate.
Gas combustion produces more water vapor than oil, so your old cap and liner are now handling a different moisture load than they were designed for. We frequently find that pre-conversion caps are undersized or improperly vented for gas appliances, trapping condensation that accelerates crown deterioration. An inspection will tell us whether your current cap can be adapted or if a new multi-flue cap with proper clearances is the safer choice. Estimates are free — call (866) 884-9512.
Yes — a cracked or poorly sealed crown can allow exhaust gases to leak into the space between the flue liner and the chimney masonry, then seep through shared party-wall joints into your home or your neighbor’s. This is especially dangerous in Borough Park’s attached row homes where flue gases can migrate horizontally. If you smell gas, treat it as an emergency: ventilate the space, leave if concentrations are high, and call us immediately at (866) 884-9512 for same-day inspection.
Every 5–7 years is the practical interval for crown coating in Brooklyn’s climate, though we recommend annual inspection to catch early failure. The repeated freeze-thaw cycles here — moisture saturating the crown in November, freezing hard in January, thawing and refreezing weekly — degrade sealants faster than in milder climates. A $200 coating every six years prevents a $1,200 reconstruction. Call (866) 884-9512 to schedule an inspection and we’ll check your current coating’s condition.
We can install an individual cap on the inactive flue while maintaining proper venting for the active ones, but we need to verify that the unused flue isn’t contributing to draft dynamics for the remaining appliances. In some Borough Park configurations, capping one flue alters the pressure balance and causes back-drafting. Robert will test the system before and after to ensure safe operation. For a proper assessment, call (866) 884-9512 for a free estimate.
