We’ve worked on chimney stacks from Lawrence Park to Midland Gardens and along Palmer Road for over 42 years. Bronxville’s homes are different from what you’ll find in newer Westchester developments. The village’s pre-1930 Tudor Revival and Colonial Revival manor homes were built with multiple fireplaces sharing tall masonry chimneys, original lime mortar, and clay tile liners that are now 80-120 years old. That age isn’t abstract - it shows up as spalled crowns, cracked flue tiles, and cross-drafting between flues that homeowners only notice when smoke starts backing up into the living room. Our Chimney Cap & Crown team knows these chimneys because we’ve inspected and repaired hundreds of them.

Our Chimney Cap & Crown Services in Bronxville
Multi-Flue Cap Installation
Many of Bronxville’s 1910s-1920s manor homes have two or three separate flues sharing one large chimney stack. A single cap per flue leaves gaps where rain and debris enter. We install custom multi-flue caps - often in copper or stainless steel - that shelter all flues from a single top-mounted frame. This is the correct solution for the village’s signature multi-fireplace homes. We measure on site, fabricate to fit, and install with proper clearance and anchoring.
Crown Replacement
Original lime-mortar crowns on 100-year-old Bronxville chimneys spall from Westchester’s repeated freeze-thaw cycles. Once water penetrates the crown, it saturates the masonry below and degrades clay tile liners. Crown replacement involves removing the failed crown, pouring a new cast-in-place concrete crown with proper slope and overhang, and sealing with a rubberized elastomeric coating. For a typical two-flue stack in Bronxville, replacement runs $680-$890. We serviced a 1928 Georgian Colonial on Paxton Avenue where the crown had hairline cracks, allowing water to spall the lime mortar and saturate three shared flues. We replaced the crown with a cast-in-place concrete crown coated with a rubberized elastomeric sealant, installed a multi-flue copper cap over all three flues, and lined two active flues with DuraFlex. The homeowner now avoids cross-drafting and water damage every freeze-thaw cycle.
Crown Coating
When a crown has minor cracking but sound structural integrity, crown coating is the economical alternative to full replacement. We use HeatShield or similar professional-grade elastomeric sealants formulated for chimney crowns - not hardware-store caulk. The coating fills hairline cracks, creates a waterproof membrane, and extends crown life 5-10 years if the underlying concrete is solid. In Bronxville, where many crowns are original soft lime mortar rather than modern concrete, we assess carefully. Coating a deteriorating lime crown is throwing good money after bad. We’ll tell you straight. Crown coating typically runs $340-$520 in Bronxville.
Cap Replacement
Missing, rusted, or improperly sized caps are common on Bronxville chimneys where original caps were lost to wind, tree impact, or simple age. A cap that is too small channels water into the flue. No cap at all invites birds, squirrels, and leaf debris that block flues and accelerate liner damage. We replace with correctly sized Gelco or Copperfield caps, secured with proper mounting hardware. Single-flue cap replacement in Bronxville runs $280-$450; multi-flue custom caps run higher depending on stack dimensions.

Trusted Brands We Service in Bronxville
We stock DuraFlex stainless steel liners, HeatShield crown coatings, and Copperfield caps at our New York City facility, which means most Bronxville customers don’t wait for parts. For custom multi-flue caps on the village’s larger chimney stacks, we work with Gelco and Olympia Chimney for fabricated solutions that fit the irregular dimensions of pre-war masonry. No builder-grade substitutes. The materials we use are the same ones specified by chimney professionals nationwide, and we install them with the same care we’d expect on our own homes.
Common Chimney Cap & Crown Problems We See in Bronxville Homes
- Spalled lime-mortar crowns from freeze-thaw damage. Westchester’s hard winters hit Bronxville’s century-old chimneys hardest. Water enters micro-cracks in the crown, freezes overnight, and expands the crack wider. By spring, the crown surface is flaking and the mortar joints below are soft. We see this on nearly every pre-1930 chimney we inspect in the 10708 ZIP code.
- Cross-drafting between shared flues. Many Bronxville homes have two or three fireplaces sharing one chimney stack. When one flue is unused and uncapped, or when the crown has gaps, fireplace smoke can backdraft into the adjacent flue and emerge in an upstairs bedroom. This is dangerous and often hidden until a Level-2 camera inspection checks each flue independently.
- Cracked decorative chimney pots and clay crowns. The village’s older homes often feature ornamental chimney pots that have endured a century of thermal stress. The clay cracks, the crown beneath it cracks, and flue gases escape into the attic space. We replace with functional, properly vented caps that preserve the home’s appearance while meeting modern safety standards.
- Improperly sized or missing caps on multi-flue stacks. A single small cap on a three-flue stack leaves two flues exposed. Rain runs straight down the tile liners, accelerating clay deterioration and creosote buildup. We measure the full stack and install a multi-flue cap with proper mesh screening and minimum 5-inch clearance.

Bronxville’s housing stock costs more to maintain than a 1990s colonial in a newer suburb. That’s not a sales pitch. It’s a fact of century-old masonry, original materials, and the skilled labor required to work on it correctly. We don’t cut corners on chimneys that have stood for 100 years and need to stand for 100 more.

FAQs - Chimney Cap & Crown in Bronxville
No - a single multi-flue cap properly sized for your chimney stack is the better solution. Two separate caps leave a gap between them where rain and debris enter, and they don’t address the cross-drafting risk common in Bronxville’s shared-flue chimneys. We measure your stack on site and fabricate a multi-flue cap with proper mesh, clearance, and slope. Call (855) 950-3861 for an exact quote - estimates are free.
Every year, without exception. Lime mortar is softer and more porous than modern Portland cement crowns, and Westchester’s freeze-thaw cycles accelerate deterioration. Annual inspection catches hairline cracks before they become spalled, saturated masonry and interior water damage. We include crown condition in every Level-2 inspection, with photos you can see. Call (855) 950-3861 to schedule - estimates are free.
Yes - a cracked or spalled crown is the most common source of chimney-related interior water damage in Bronxville’s pre-1930 homes. Water enters through the crown, runs down the flue tiles, and exits at the chimney breast where it meets your ceiling. The stain location (directly adjacent to the chimney stack) is the tell. We inspect the crown with a camera and moisture meter to confirm before recommending repair or replacement. Call (855) 950-3861 - we’ll find the source.
A crown coat is a surface sealant applied to sound concrete - it fills cracks and waterproofs but adds no structural strength. A full crown replacement removes the failed crown and pours new cast-in-place concrete with proper slope, overhang, and elastomeric sealing. For your 1918 home, the critical question is whether the existing crown is original lime mortar or a later concrete replacement. Lime mortar cannot be successfully coated; it will continue spalling beneath the sealant. We determine this during inspection and recommend honestly. Crown coating runs $340-$520; full replacement runs $680-$890. Call (855) 950-3861 for an assessment.
It’s common but incorrect. Many of the village’s multi-flue stacks were originally built with decorative chimney pots or small single caps that have been lost to age. One cap on three flues leaves two flues exposed to rain, debris, and animal entry. We regularly find this configuration on Lawrence Park and Midland Gardens homes. The proper repair is a custom multi-flue cap sheltering all three flues with adequate clearance and mesh screening. Call (855) 950-3861 for a measurement and quote - estimates are free.
