Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Hearthstone Chimney Co. Is Forest Hills’s Preferred Chimney Cap & Crown Company
We’ve been answering the phone with a live person for over 42 years, and that hasn’t changed. Forest Hills homeowners call us because we’ve documented the condition of their chimney with photos and a plain-English verdict before we quote a dollar - no surprises on the bill, no pressure to commit on the spot.
Our technicians are background-checked and uniformed, and most cap and crown jobs in Forest Hills are completed in a single visit. We carry the 90-Day Done Right Promise in writing: if it’s not right, we come back, no arguing, no paperwork to dig up. That matters in a neighborhood where many homeowners have lived in the same house for thirty years and remember every contractor who didn’t return their call.
We understand the local architecture. The 1910s-1940s Tudor Revival and English Arts and Crafts homes that define Forest Hills, especially in the Gardens, were built with multi-flue chimney stacks designed for coal. Those original clay-tile liners and lime mortar joints need a different approach than a 1990s suburban build. We don’t guess. We inspect, photograph, and explain what we’re seeing before we recommend anything.
Our Chimney Cap & Crown Services in Forest Hills
Multi-Flue Cap Installation
Multi-flue caps are what most Forest Hills homes actually need, though many homeowners don’t realize it. Those tall, decorative chimney stacks on Tudor Revival homes along Greenway South and Ingram Street often contain two, three, or four flues - some active, some abandoned coal-era openings left uncapped for decades. Our crew was called to a 1920s Tudor on Greenway South where the multi-flue stack had three abandoned coal-era flues pulling cold air down into the working fireplace, killing draft and feeding third-degree creosote buildup in the smoke chamber. We installed a custom multi-flue copper cap from Copperfield sized to the original stack footprint so it read as original to the roofline, then repaired the spalling crown and coated it to shed water away from the lime mortar joints. The dead-flue downdraft stopped, the fireplace drafted clean, and the Gardens Corporation approved the cap profile without a revision. Multi-flue caps in Forest Hills typically run $450-$890 depending on stack dimensions and material.
Crown Repair
The chimney crown is the concrete or mortar slab that seals the top of your chimney stack, and it’s where water does its worst damage. In Forest Hills, Queens’ freeze-thaw cycle - temperatures crossing the freezing threshold 40-60 times per winter - is particularly hard on the century-old lime mortar joints in Forest Hills Gardens’ original masonry chimney stacks, accelerating spalling and joint erosion that requires repointing before water infiltration damages interior flue tiles. Crown repair in Forest Hills runs $280-$550 for partial resurfacing and joint repointing, or $650-$890 if the crown has cracked through and needs rebuilding. We use professional-grade crown coating compounds formulated for the thermal expansion these old stacks experience.
Crown Coating
Crown coating is a preventive treatment we recommend for Forest Hills chimneys where the crown is intact but the surface is porous or hairline-cracked. The coating forms a flexible, waterproof membrane that bridges small cracks and sheds water away from the masonry below. For homeowners in the Gardens and along Ascan Avenue with original 1920s stacks, this can add years of life before a full rebuild is necessary. Crown coating in Forest Hills typically costs $280-$420, including surface prep and application. We don’t coat over active leaks or structural damage - we photograph what we find and show you why.
Cap Replacement
Cap replacement sounds simple until you’re trying to match a profile that the Forest Hills Gardens Corporation will approve. In Forest Hills Gardens, exterior chimney caps and crowns are visible from the street and fall under the Forest Hills Gardens Corporation’s architectural review authority, so installation specs and cap materials are constrained in ways they are not anywhere else in Queens. We’ve replaced caps on homes near Station Square where the original galvanized cap had rusted through, and on Burns Street where a big-box store cap looked wrong against the slate roof from fifty feet away. We stock caps from Famco and Olympia Chimney in profiles that pass review, and we measure on-site to get the fit right. Cap replacement in Forest Hills runs $320-$650 for standard sizes, or $550-$890 for custom multi-flue fabrication.

Trusted Brands We Service in Forest Hills
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes. For Forest Hills homeowners, that means we can often source the right cap profile or crown coating compound without a multi-week special order. We keep common multi-flue cap sizes and crown repair materials in stock because we’ve learned what these 1910s-1940s stacks need. The brands we use are the same ones specified by chimney professionals nationwide, and we choose the right product for your specific flue configuration, not whatever’s cheapest this week.
Common Chimney Cap & Crown Problems We See in Forest Hills Homes
- HOA rejection because the cap profile clashes with the Tudor roofline. In Forest Hills Gardens, the architectural review authority rejects cap installations that are visible from the street and don’t match the historic character. We measure the original stack, source caps in appropriate materials and finishes, and document the installation to satisfy review requirements.
- Single-flue caps leaving abandoned coal-era flues open to the sky. Many Forest Hills Gardens Tudor homes still carry abandoned coal-flue openings within a multi-flue chimney stack alongside an active fireplace flue. Technicians frequently find these dead flues uncapped, acting as cold-air inlets that cause downdraft problems in the working fireplace - a failure mode almost unique to this pocket of early-20th-century planned housing in the borough.
- Freeze-thaw damage spalling century-old lime mortar. Queens’ freeze-thaw cycle attacks the original mortar joints on pre-war stacks, especially those with existing crown cracks that let water saturate the masonry. We repoint with compatible lime-based mortars where appropriate, not modern Portland cement that traps moisture and accelerates deterioration.
- Shared chimney chases in pre-war apartment buildings with no individual flue access. The six- and seven-story brick apartment buildings along Queens Boulevard feature shared masonry chimney chases serving boiler flues and individual apartment fireplaces, complicating liner inspections and cap installation. We coordinate with building management to access common areas and document which flues serve which units.

FAQs - Chimney Cap & Crown in Forest Hills
Yes, if your home is within Forest Hills Gardens, exterior chimney modifications visible from the street require architectural review and approval before work begins. The Forest Hills Gardens Corporation reviews cap profiles, materials, and finishes to ensure compatibility with the historic Tudor Revival streetscape. We submit documentation with our installation specs and have never had a cap rejected when we’ve measured and specified correctly. Call (516) 206-6672 and we’ll walk you through the approval timeline.
The most common cause in Forest Hills is uncapped abandoned coal-era flues in a multi-flue stack pulling cold air downward and disrupting draft in the working fireplace. This happens almost exclusively in the early-20th-century planned housing of Forest Hills Gardens, where original multi-flue stacks were built for coal and later partially converted. A single-flue cap on the active flue doesn’t solve it - you need a multi-flue cap that seals all openings. We diagnose this with a camera inspection and smoke test, then fabricate a cap sized to your stack. Call (516) 206-6672 for an exact quote - estimates are free.
We can inspect and service your individual flue, but we need building management to grant access to the common chimney chase and roof area. The pre-war six- and seven-story brick apartment buildings along Queens Boulevard feature shared masonry chases serving multiple units plus boiler flues, so we coordinate with your super or management company to schedule access and document which flue serves which unit. We provide photos and a plain-English verdict for your records and theirs. Call (516) 206-6672 to discuss scheduling with your building.
Most original lime mortar crowns in Forest Hills Gardens need inspection every 3-5 years, with repointing or coating typically required every 7-12 years depending on exposure and prior maintenance. The freeze-thaw cycle here is harder on century-old lime mortar than on modern Portland cement, but that’s actually an advantage - lime mortar is more repairable and breathable, so timely maintenance prevents the major rebuild that a sealed, cracked crown would require. We document crown condition with photos during every inspection and tell you plainly when work can wait. Call (516) 206-6672 for a free inspection.
We strongly recommend capping all flues, including abandoned ones, because uncapped dead flues become cold-air inlets that cause downdraft, creosote buildup, and moisture damage inside the stack. In Forest Hills Gardens, this is particularly important - those abandoned coal-era flues are a defining feature of the local housing stock and a defining failure mode when left open. A multi-flue cap sized to your stack’s footprint solves the problem while maintaining the visual continuity the Gardens Corporation requires. Single-flue caps on multi-flue stacks are almost always a mistake here. Call (516) 206-6672 for an exact quote - estimates are free.
