Why Hearthstone Chimney Co. of New York City Is Mount Vernon’s Preferred Chimney Cap & Crown Company
Mount Vernon homeowners don’t call us for flash.

We document every inspection with photos you can see and a plain-English verdict. No jargon, no upsell.
Our reputation here is built on row-house specifics. We understand party-wall chimneys, gas-conversion flues, and the accelerated mortar deterioration that comes with both. Technicians are background-checked and uniformed; they arrive when we say they will. The 90-Day Done Right Promise covers every crown repair and cap installation in writing - if it’s not right, we come back, no paperwork, no arguing.
Most Mount Vernon calls reach us within minutes, not hours. We dispatch from our New York City base and know the Cross County Parkway corridor well enough to estimate arrival without map-checking. For emergency water intrusion, we prioritize 10552, 10553, 10557, and 10550 ZIP codes same day.
Our Chimney Cap & Crown Services in Mount Vernon
Crown Repair
Crown deterioration is nearly universal on Mount Vernon’s pre-WWII chimneys. The original concrete or mortar wash was never meant to survive forty years of freeze-thaw, let alone ninety. In south Mount Vernon, especially the 10550 and 10553 blocks where chimneys face north or west and stay wet for days, we regularly see crowns cracked clean through, funneling water directly into the flue and the party wall beyond.
Our crown repair process starts with removal of loose material down to sound substrate. We form a proper concrete crown with adequate overhang and drip edge, sloped to shed water away from the brick. For chimneys with active gas conversions producing acidic condensate, we specify a CrownCoat or HeatShield sealant compatible with your appliance type. Done right, and we stand behind it.
Cap Installation & Replacement
A missing or rusted-through cap is an open invitation. Squirrels nest in flues here every spring. Rain washes mortar joints bare. We install stainless steel and copper caps from Famco and Copperfield, sized to your flue count and configuration. Single-flue caps suit many Mount Vernon two-family conversions; multi-flue caps cover the broader chimney tops common on Hartley Street and Morton Street row houses.
Every cap we install includes proper screening, correct clearance above the flue tile, and secure mounting that won’t lift in a nor’easter. We measure on-site. We don’t guess.
Multi-Flue Cap
Mount Vernon’s attached row homes frequently share a single chimney breast with multiple flues serving separate units. A multi-flue cap protects the entire assembly with one properly sloped cover, eliminating the gaps between individual caps where water pools and freezes.
We recently worked a Hartley Street row home where a missing crown and unlined flue allowed freeze-thaw damage to crumble the top three feet of brick; our crew installed a multi-flue stainless cap with a HeatShield liner to remedy gas appliance drafts and protect the adjoining units. That old coal-era chimney hadn’t been inspected since the 1970s. Multi-flue caps are our standard recommendation for any shared chimney in 10550 or 10553.
Custom Cap
Some Mount Vernon chimneys defy standard sizing. Oversized legacy flues, irregular brick courses, or ornamental corbelling from the 1920s require fabricated solutions. We measure, sketch, and order custom stainless or copper caps through Copperfield and Famco with typical turnaround of five to seven business days. Installation follows, with the same no-surprise upfront pricing we apply to every job.
Crown Coating
For crowns with minor cracking and adequate structural thickness, a professional-grade coating extends service life five to ten years. We use HeatShield and CrownCoat products, never hardware-store brush-on sealers that trap moisture and accelerate spalling. Coating is not a substitute for rebuild on a crown that’s lost its structural integrity, and we’ll tell you plainly which applies to your chimney.

Common Chimney Cap & Crown Problems We See in Mount Vernon Homes
- Crown deterioration from freeze-thaw and acidic condensate. Mount Vernon’s gas conversions produce moisture that original coal-era crowns were never designed to handle. The combination eats through mortar wash and concrete alike, leaving the flue top exposed to every rainfall.
- Oversized legacy flues lacking modern liners. Built for coal, now serving gas, these flues draft poorly and run cool. Crowns crack under the thermal stress, and carbon monoxide can back-draft into adjoining units through shared party walls.
- Original mortar and brick spalling on north-facing exposures. Dense urban blocks in 10550 and 10553 limit sun exposure. Chimneys stay wet longer, freeze harder, and shed surface brick in sheets. The crown can’t protect masonry that’s already compromised.
- Missing or improperly installed caps from prior repairs. We find upside-down pots, hardware-store galvanized caps rusted through, and caps mounted too low to allow proper draft. Each is a leak waiting to happen, or already happening.

FAQs - Chimney Cap & Crown in Mount Vernon
A new crown alone will not fix back-drafting; the root cause is usually an unlined or improperly sized flue combined with negative pressure in the building envelope. In Mount Vernon’s attached row homes, we inspect both flues in a shared chimney, test draft performance under actual operating conditions, and typically recommend a stainless liner paired with a properly sealed crown and multi-flue cap. The crown stops water intrusion; the liner fixes draft. Call (855) 950-3861 for a Level-2 camera inspection - estimates are free.
Every twelve months, without exception, given the freeze-thaw severity and gas-conversion condensate typical in 10550 and 10553. We find that chimneys in these blocks deteriorate two to three times faster than standalone suburban equivalents. An annual inspection catches crown cracking before water reaches the flue liner and party wall. Call (855) 950-3861 to schedule; we document every visit with photos you can see.
Yes, provided the flue tile is structurally sound and the chimney is properly lined for its current fuel type. We frequently repair crowns on Mount Vernon’s 1900-1940 chimneys after verifying liner compatibility with the gas appliance below. If the flue tile is fractured or the chimney is unlined, we recommend simultaneous liner installation with HeatShield or DuraFlex materials. Call (855) 950-3861 for an inspection and plain-English verdict.
We install multi-flue caps from Famco and Copperfield, fabricated in stainless steel or copper with proper mesh screening and slope. Both brands offer the span and height clearances required for Mount Vernon’s wider, multi-flue chimney tops. We measure on-site and order to fit, with typical installation completed in one visit once materials arrive. Call (855) 950-3861 for sizing and pricing.
If the crown retains at least three-quarters of its original thickness and the reinforcement is intact, a professional coating or partial rebuild is viable. If the crown has eroded to exposed mesh, crumbled to loose aggregate, or separated from the brick shelf, full replacement is the only lasting solution. We assess this on every Morton Street call; the north-facing exposure there typically accelerates deterioration. Call (855) 950-3861 for a free inspection and honest recommendation.
