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.

AfterFast, Reliable Chimney Cap & Crown Across Sheepshead Bay
Chimney cap and crown repair in Sheepshead Bay typically runs $180-$850 depending on whether you need a simple coating, a cap replacement, or full crown rebuild, and most jobs are completed in a single visit with our crew already working the neighborhood. For the two-family brick homes that define this area - many with multiple flues and original masonry from the 1920s to 1950s - the salt-laden air off the bay destroys galvanized caps and soft-mortar crowns far faster than inland Brooklyn ever sees. We’re Hearthstone Chimney Co., and our technicians are in Sheepshead Bay every week addressing exactly this problem. Call (516) 613-3035 and a live person will pick up, 24 hours a day.
Why Hearthstone Chimney Co. Is Sheepshead Bay’s Preferred Chimney Cap & Crown Company
We’ve been answering the phone with a live person for over 42 years, and that matters in Sheepshead Bay where homeowners remember which contractors showed up and which ones didn’t. Our dispatch and scheduling are coordinated from our New York City office, but our crews serve Sheepshead Bay locally - we know the difference between a house on Emmons Avenue catching full salt spray off the bay and one a few blocks inland on Avenue Z.
Our Level-2 camera inspections end with photos you can see and a plain-English verdict. No jargon, no scare tactics. If your crown can be coated instead of rebuilt, we’ll tell you.

Background-checked, uniformed technicians complete most jobs in a single visit. No-hassle upfront pricing means the number on the estimate is the number on the invoice. And our permanent 5% Senior and Veteran discount applies to every cap and crown job in Sheepshead Bay.
Our Chimney Cap & Crown Services in Sheepshead Bay
Cap Installation
New cap installation on a Sheepshead Bay chimney starts with understanding what the bay air will do to it. For a single-flue cap on a typical two-family home near Ocean Avenue, we measure on-site and fabricate from stainless steel or copper - materials that laugh at salt spray instead of surrendering to it in five years. Our Chimney Cap & Crown team installs DuraFlex and Copperfield caps with proper clearance and secure mounting, so wind off the water doesn’t lift them. Most installations run $280-$450 and are done in under two hours.
Cap Replacement
This is where we spend most of our time in Sheepshead Bay. Galvanized caps rust through in 5-7 years here - roughly half the lifespan they see in inland Brooklyn neighborhoods like Flatbush or Midwood. Homeowners on Emmons Avenue and the streets running down to the bay know this already; they’ve watched it happen. We remove the corroded cap, inspect the flue mouth for water damage, and install a replacement that fits correctly. A standard stainless replacement runs $320-$480. Multi-flue setups cost more but eliminate the gaps between individual caps where water and salt air penetrate.
Crown Repair
The crown is the concrete or mortar slab that seals the top of your chimney, and on Sheepshead Bay’s 1920s-1950s two-family homes, it’s often original soft mortar that has never been addressed. Freeze-thaw cycling cracks it. Salt-moisture intrusion erodes it. Once water gets through, the brick below spalls and the flue liner deteriorates. Crown repair means removing loose material, rebuilding with proper slope and overhang, and sealing the edge where crown meets brick. A full rebuild on a multi-flue chimney runs $650-$850. We photograph before, during, and after - you’ll see exactly what was wrong and how we fixed it.
Crown Coating
Not every cracked crown needs rebuilding. If the structural integrity is sound and the damage is surface-level, we apply HeatShield crown coating - a professional-grade elastomeric sealant that flexes with temperature changes and blocks salt-moisture penetration. At $180-$320, coating is often the right choice for Sheepshead Bay homeowners who caught the problem early. We don’t recommend coating over crowns that are too far gone; our camera inspection and photo report give you the honest verdict. Done right, a coated crown adds 10-15 years of protection against the bay’s relentless air.
Multi-Flue Cap
Most two-family homes in Sheepshead Bay have multi-flue chimneys serving separate heating systems or a boiler and fireplace combination. Individual caps leave gaps. A custom multi-flue cap from Copperfield or Famco covers the entire chimney top with a single slope, single screen, and no seams for water to find. We measure on-site, fabricate to fit your specific flue spacing, and install with proper clearances for each appliance. Multi-flue caps run $480-$720 installed. For large properties with multiple fireplaces and flues - the homes we see regularly off Ocean Avenue and Avenue Z - this is usually the smarter long-term investment.
Custom Cap
Some Sheepshead Bay chimneys need what no catalog carries. Oversized flues, unusual projections, or architectural requirements on older homes near the bay. We fabricate custom stainless and copper caps to exact specifications, with welded seams and proper screening. Custom work starts around $620 and scales with complexity. Every custom cap carries the same 90-Day Done Right Promise as our standard installations.

Trusted Brands We Service in Sheepshead Bay
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield - no builder-grade substitutes that fail early in salt air. For Sheepshead Bay’s marine environment, we stock stainless steel and copper caps locally, not aluminum or galvanized that corrode. HeatShield crown coating is our go-to for surface-level crown protection. Famco and Copperfield multi-flue caps are fabricated with heavier-gauge metal and better welding than what you’ll find at supply houses serving general contractors. Fast turnaround matters here: when a cap fails in November, you don’t want to wait three weeks for parts. We keep common sizes in stock and custom-fabricate within days, not weeks.
Common Chimney Cap & Crown Problems We See in Sheepshead Bay Homes
- Galvanized caps rusted through in 5-7 years. The salt spray off Sheepshead Bay is relentless. Homeowners on streets like Emmons Avenue and the blocks closest to the water regularly find their “new” galvanized cap has holes, the screen has detached, and water is running straight into the flue. Stainless steel or copper is the only sensible choice here.
- Soft-mortar crowns cracked and spalling. Original crowns on 1920s-1950s two-family homes were never built to modern standards. Freeze-thaw cycling opens cracks. Salt-moisture intrusion follows. The brick beneath the crown begins to spall, and soon you’re looking at crown rebuild plus brick repair instead of a simple coating.
- Hidden moisture damage from Hurricane Sandy’s 2012 surge. Many chimneys in this flood-zone neighborhood took water during Sandy that compromised flue integrity in ways that only become apparent during a Level-2 inspection. We’ve found clay tile liners with cracked sections, deteriorated mortar joints, and rusted dampers that traced back to surge moisture trapped in the chimney mass. The cap and crown may look intact while the flue below is failing.
- Improperly fitted caps leaving gaps for water and wildlife. Caps installed without proper measurement - or bought off-the-shelf at a hardware store - don’t seal correctly. Gaps between cap and flue, or between multiple individual caps on a multi-flue chimney, let in rain, salt air, and squirrels. On a two-family home with multiple heating appliances, that’s a risk you don’t take.

FAQs - Chimney Cap & Crown in Sheepshead Bay
Every 12 months, without exception, because the salt-air exposure here accelerates deterioration dramatically. Inland Brooklyn homeowners might stretch to two years; on Emmons Avenue or any block catching bay spray, annual inspection catches crown cracks and cap corrosion before water reaches the flue. Our $89 seasonal tune-up includes cap, crown, and basic flue inspection. Call (516) 613-3035 to schedule - estimates are free.
You almost certainly do, because individual caps leave gaps between flues where water, salt air, and animals enter - and on a two-family home with multiple heating appliances, that’s multiplied risk. A custom multi-flue cap covers the entire chimney top with a single slope and integrated screen, eliminating those failure points. We measure your specific flue spacing on-site and fabricate from Copperfield or Famco in stainless or copper. Most Sheepshead Bay multi-flue installations run $480-$720. Call (516) 613-3035 and we’ll show you exactly what your current setup is missing.
Crown coating applies a flexible sealant over a structurally sound crown to prevent moisture intrusion - it’s prevention, not reconstruction, and costs $180-$320. Crown repair removes deteriorated material and rebuilds the crown with proper slope, thickness, and drip edge - it’s necessary when the crown is cracked through, spalling, or no longer shedding water correctly, and runs $650-$850. In Sheepshead Bay’s salt-air environment, we see more crowns that need full repair than coating can save, especially on original 1920s-1950s construction. Our camera inspection and photo report give you the honest distinction - we don’t coat a crown that needs rebuilding. Call (516) 613-3035 for a free evaluation.
Yes, absolutely. The 2012 storm surge left moisture trapped in chimney masonry across this flood-zone neighborhood, and that moisture continues to degrade clay tile liners, corrode metal components, and weaken mortar joints years later. Damage often hides until a Level-2 camera inspection reveals cracked tiles or deteriorated joints that trace back to surge saturation. We’ve found Sandy-related compromise in chimneys that looked fine from the outside - cap intact, crown apparently sound - but the flue below was failing. If your home flooded in 2012 and the chimney hasn’t had a camera inspection since, that’s the next step. Call (516) 613-3035.
Yes. Galvanized caps rust through in 5-7 years here due to relentless salt-air exposure - roughly half their inland lifespan. Stainless steel or copper caps cost more upfront but outlast galvanized by a decade or more in this marine environment. On a two-family home with multiple flues, replacing three individual galvanized caps every five years costs more than one stainless multi-flue cap that lasts fifteen. It’s not upselling. It’s arithmetic that every Sheepshead Bay homeowner near the water learns eventually. Call (516) 613-3035 and we’ll show you what the salt has done to your current cap.
Ready to Protect Your Sheepshead Bay Chimney?
On a two-family brick house off Ocean Avenue near the bay, our tech found a galvanized cap rusted through and a soft-mortar crown with spalling brick around multiple flues. We replaced the cap with a custom stainless multi-flue model from Copperfield, coated the crown with HeatShield, and confirmed the original clay tile flue liner was still sound enough to avoid relining. The homeowner now has a cap that should outlast the next decade of salt air. That’s how we work - photos you can see, a plain-English verdict, and a job done right that we stand behind.
Your chimney cap and crown are the only barriers between your flue and everything the bay throws at it. Annual inspection, honest assessment, and the right materials for this specific environment - that’s what keeps a Sheepshead Bay chimney safe and dry. Call (516) 613-3035 now.
