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 Amityville’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. Homeowners in Amityville call us because we document every inspection with photos and a plain-English verdict, back every job with the 90-Day Done Right Promise in writing, and never recommend work you can’t see for yourself.
Our technicians know the difference between a chimney on Albany Avenue and one on a canal street off Bayview. The salt-laden marine air that blows off the Great South Bay destroys crowns and mortar joints at a rate inland Nassau County sweeps rarely encounter. We’ve rebuilt crowns on Cape Cods near the water that looked forty years older than identical chimneys just east of Route 110. That local knowledge matters when we’re deciding whether a crown can be coated or needs full reconstruction.
Dispatch and scheduling are coordinated from our New York City office, but our crews live and work on Long Island. They arrive in marked vehicles, in uniform, background-checked, with no-hassle upfront pricing. The number on the estimate is the number on the invoice.
Our Chimney Cap & Crown Services in Amityville
Cap Installation
New cap installation in Amityville runs $280-$520 for standard stainless steel models, with custom copper or multi-flue caps ranging higher. Most Amityville homes we see need more than just a cap dropped on top. The post-WWII Cape Cods and split-levels that dominate the village often have flue liners cracked from decades of oil-heat cycling, and a cap alone won’t stop water from entering through a fractured crown beneath it. We install caps from Olympia Chimney and Famco with proper overhang and screen clearance, sized to your flue count and appliance type.
Cap Replacement
Cap replacement in Amityville costs $240-$480 for like-for-like stainless steel swaps, though we often find the underlying crown has deteriorated past the point where a new cap alone helps. On canal-side homes near the bay, the original cap frequently rusted through because salt spray accelerated corrosion at the mounting points. We replace with marine-grade materials and inspect the crown substrate before we quote. If the crown is sound, you get a new cap and a ten-year outlook. If it’s not, we show you the camera footage and explain why.
Crown Repair
Crown repair in Amityville spans $450-$920 for coating and minor crack sealing, but full crown rebuilding on salt-damaged canal-side chimneys runs $1,200-$1,850. Here’s where our local experience counts. The “South Bay crown decay” we see on waterfront-adjacent homes - fractured concrete, spalled top brick courses, exposed liner - almost always requires rebuilding, not coating. A sealant layer over crumbling substrate buys you two seasons before the water gets back in. We use professional-grade crown mix with proper overhang and expansion joints, poured to shed water away from the brick face.
Crown Coating
Crown coating in Amityville costs $380-$650 and makes sense only when the crown structure is fundamentally sound. We apply this on inland Amityville properties where freeze-thaw cracking is minor and the crown still has adequate slope and thickness. On canal streets, we rarely recommend coating as a standalone fix. The salt-driven spalling and mortar loss we document with our Level-2 camera inspection usually reveals damage that coating would conceal, not solve. When coating is appropriate, we use HeatShield-compatible formulations with proper surface prep.
Multi-Flue Cap
Multi-flue cap installation in Amityville runs $680-$1,200 depending on span and material. Many of the village’s 1950s and 1960s split-levels have multiple flues clustered on a single chimney - one for the original fireplace, another for the boiler, sometimes a third for a water heater. A multi-flue cap from Gelco or Copperfield covers the entire chimney top with a single sloped lid that sheds water and salt spray more effectively than individual caps with gaps between them. We measure on site and fabricate to fit.
Custom Cap
Custom cap fabrication in Amityville starts around $890 for copper and runs to $1,600+ for complex multi-flue spans with decorative elements. On a canal-front Cape Cod off Bayview Avenue, our tech found “South Bay crown decay” - the chimney crown fractured and the top two courses of brick spalling from salt exposure, with the clay-tile flue liner cracked and offset where a modern gas boiler had been tied in. We rebuilt the crown, reset the spalled brick, and installed a custom multi-flue cap in copper to shed salt spray. The homeowner watched the whole scope on camera before we quoted a dollar. Custom copper weathers to a patina that matches Amityville’s coastal architecture and outlasts any off-the-shelf option.

Trusted Brands We Service in Amityville
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Amityville homeowners, this means we stock the common cap sizes and crown repair materials for post-WWII chimney dimensions right on our trucks. Most jobs finish in one visit. If you need a custom copper cap for a South Bay canal-front home, we fabricate locally and install within the week. The brands matter because a cap that rusts through in three seasons costs more than one that lasts twenty.
Common Chimney Cap & Crown Problems We See in Amityville Homes
- Salt-laden marine air off the Great South Bay spalls the top two brick courses and fractures the crown on canal-side homes far faster than on inland Amityville properties. Technicians working the canal streets near the bay quickly learn to spot this pattern. The crown concrete crumbles, the brick face flakes away, and water enters the flue system. Most of these crowns need full rebuilding, not a sealant coat.
- Post-WWII clay-tile flues undersized for modern gas appliances crack and offset, letting moisture wick into the crown and accelerate freeze-thaw damage that a simple coating won’t stop. Amityville’s housing stock is dominated by Cape Cods, ranches, and split-levels built between 1945 and 1970 with clay-tile liners sized for oil-fired boilers. When homeowners convert to gas, the cooler flue gases condense, the tiles crack, and the crown above absorbs the moisture.
- Original crowns poured with inadequate overhang and no expansion joint crack at the flue, letting water run behind the crown and down into the smoke chamber and firebox. This is nearly universal on Amityville’s older stock. The concrete was sloped toward the flue instead of away from it, or poured flush with the brick face. Water follows gravity straight into the masonry.
- Hurricane Sandy’s 2012 storm surge left lingering moisture damage in chimney bases that continues to drive spalling and efflorescence in older masonry that wasn’t fully remediated. We still find Amityville homes where the crown looked fine from the ground but the Level-2 camera revealed saturated brick courses and liner displacement tracing back to flood wicking.

FAQs - Chimney Cap & Crown in Amityville
Salt-laden marine air off the Great South Bay accelerates mortar erosion and concrete spalling by a factor of years compared to inland Amityville properties. On canal-side homes, we routinely see crown fractures and brick spalling that look decades older than identical chimneys east of Route 110. The salt crystals draw moisture into the masonry, freeze-thaw cycles expand the cracks, and the crown fails. Most canal-side crowns need full rebuilding, not coating. Call (516) 614-4632 for a free camera inspection.
No. Our Level-2 camera inspection produces photos you can see and a plain-English verdict before any work is quoted. Nothing is recommended without evidence you can verify yourself. The 90-Day Done Right Promise applies only to work we’ve documented and you’ve approved. If a technician can’t show you the crack, the spall, or the liner offset on camera, we don’t quote the repair.
You need a Level-2 inspection first. The clay-tile liners in Amityville’s post-WWII Cape Cods were sized for oil-fired boilers running at higher flue temperatures. Modern gas appliances produce cooler, wetter exhaust that condenses inside those tiles, causing cracks and offsets. A new cap won’t fix a cracked liner, and a crown rebuild over a failing liner wastes money. We inspect the full system with camera documentation, then quote only what is actually needed. Call (516) 614-4632 to schedule.
Custom copper caps shed salt spray more effectively, last decades longer than galvanized or thin stainless alternatives, and can be fabricated with proper slope and overhang for your exact flue configuration. On Amityville canal-front homes, standard big-box caps often corrode at the mounting points within five to seven years. Copper weathers to a protective patina and typically outlasts the second roof. The upfront cost is higher. The replacement cost over twenty years is lower.
Every twelve months, per NFPA 211, regardless of use frequency. In Amityville specifically, the salt-air exposure and freeze-thaw cycling damage crowns and caps whether you light fires or not. A chimney that vents your gas boiler or water heater still needs a sound crown to keep water out of the flue and the liner. Annual camera inspection catches crown cracks and cap corrosion before water reaches the smoke chamber. Call (516) 614-4632 to book - estimates are free.
