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.

We’ve been providing our Chimney Cleaning & Sweep in Huntington and surrounding areas for over 42 years. Our dispatch is coordinated from our New York City office, but our crews live and work in Suffolk County. We know the difference between a 1920s Colonial on Huntington Village’s narrow streets and a waterfront stack in Lloyd Harbor facing the full force of a January nor’easter. That local knowledge changes what materials we specify and how we build.
Why Hearthstone Chimney Co. Is Huntington’s Preferred Chimney Cap & Crown Company
Huntington homeowners call us back because we document what we find. Every Chimney Cap & Crown inspection ends with photos you can see and a plain-English verdict - no jargon, no scare tactics, just what is wrong, what it costs, and what happens if you wait.
Our reputation here is built on specific jobs: the salt-eaten mortar joints we found in Centerport, the coal-era multi-flue chimneys in Huntington Village that failed Suffolk County inspection because they were never properly lined for gas, the cracked crowns in Cold Spring Harbor that let nor’easter rain straight into fireboxes. We don’t forget a house, and neither do our customers.
Calls are answered by a live person, every hour of every day. Our technicians are background-checked and uniformed. Most jobs finish in one visit. And everything we do is backed by our 90-Day Done Right Promise - in writing, no arguing. If it’s not right, we come back.
Our Chimney Cap & Crown Services in Huntington
Crown Repair
Chimney Repair in Huntington often starts with cracked crowns, and for good reason. The freeze-thaw cycle here is brutal - high humidity off Huntington Bay and Long Island Sound drives water into hairline cracks, then winter cold expands that water and fractures the masonry. South Shore chimneys don’t see this kind of accelerated damage. We repair with professional-grade crown coat from Gelco or full pour-and-form reconstruction when the crown is too far gone. For waterfront properties in Lloyd Harbor and Centerport, we specify salt-resistant mortar mixes that hold up against marine air - standard inland mixes simply don’t last here.
Crown Coating
Crown coating is our most cost-effective option for Huntington homeowners whose crowns are cracked but structurally sound. A typical crown coating in Huntington runs $280-$450. We clean the crown surface, fill active cracks, and apply a flexible, waterproof membrane that bridges hairlines and stops water infiltration before the next freeze cycle. For homes near the Sound, we often recommend re-coating on a shorter interval than the manufacturer suggests for inland use - the salt air and wind-driven rain here are simply harder on everything.
Cap Installation & Cap Replacement
A proper chimney cap is non-negotiable in Huntington. Without one, rain enters the flue directly, spalling flue liners and rusting dampers. We install caps from Olympia Chimney and Famco in stainless steel, galvanized, or copper, with mesh screening that keeps out squirrels, raccoons, and the starlings that nest in Huntington’s mature tree canopy. Single-flue caps start around $180 installed; multi-flue caps for larger chimneys run $340-$620. Every cap we install is sized to the flue and secured with proper mounting - no slip-on jobs that blow off in the first nor’easter.
Custom Cap & Multi-Flue Cap
Huntington’s older housing stock - especially the pre-1960 Colonials and Cape Cods in Huntington Village, Cold Spring Harbor, and Centerport - often has multi-flue chimneys built for coal or fuel-oil systems. These chimneys need custom caps that cover multiple flues with proper clearance and ventilation. We measure on-site and order custom caps from Copperfield that fit exactly, not approximately. A custom multi-flue cap in Huntington typically runs $480-$890 depending on size, material, and whether we need to address deteriorated crown conditions underneath. This is specialized work. We do it regularly.

Trusted Brands We Service in Huntington
We don’t use builder-grade substitutes. Our Huntington trucks stock professional-grade materials from Gelco, Olympia Chimney, and Famco - the brands that other sweeps order special and make you wait two weeks for. When we find a cracked crown or failed cap on your inspection, we can often repair it that same visit because the right materials are already on the truck. For custom work, we spec Copperfield multi-flue caps with turnaround times that keep your project moving. No surprises on the bill. The number on the estimate is the number on the invoice.
Common Chimney Cap & Crown Problems We See in Huntington Homes
- Salt-laden marine air destroys mortar joints. Technicians working the Lloyd Harbor and Centerport waterfront regularly find repointing mortar eaten down to near-void joints within 8-10 years of repair. Inland Suffolk homeowners never see this timeline. We specify salt-resistant mixes and tighter inspection intervals for waterfront properties.
- Coal-era multi-flue chimneys fail modern inspection. Huntington Village and Centerport homes with pre-1960 chimneys originally built for coal or fuel-oil are now running gas appliances through oversized, unlined flues. This combination creates draft problems, CO risk, and first-degree creosote buildup that routinely fails Suffolk County inspection.
- Nor’easter rain drives directly into crowns and flashing. Wind patterns off Long Island Sound hit Huntington’s North Shore chimneys at angles that South Shore and inland homes simply don’t face. One or two seasons of this exposure can crack crowns, spall flue liners, and rot adjacent framing if the cap and crown aren’t properly maintained.
- Freeze-thaw cycles accelerate crown cracking. The high ambient humidity from Huntington Bay intensifies water infiltration into hairline cracks. When temperatures drop, that water expands and fractures the crown concrete far faster than drier inland climates would cause.

FAQs - Chimney Cap & Crown in Huntington
Salt-laden marine air off Huntington Bay accelerates mortar erosion and concrete spalling by a factor that surprises most transplants from inland Suffolk. The chloride ions in that air penetrate micro-cracks and accelerate freeze-thaw damage, while wind-driven rain hits at angles that inland chimneys rarely face. We specify salt-resistant crown mixes and recommend inspection intervals roughly 30% shorter than mainland standards for waterfront properties. Call (631) 776-4075 to schedule - estimates are free.
Your chimney was engineered for a coal-fired boiler and fireplace, not a modern gas furnace. The flue is almost certainly oversized for gas appliances, which creates sluggish draft, condensation, and first-degree creosote buildup - all of which violate current Suffolk County code. We regularly find this exact scenario in Huntington Village, Cold Spring Harbor, and Centerport. A proper liner installation combined with Heatshield in Huntington for relining and a correctly sized custom multi-flue cap typically resolves it. Call (631) 776-4075 for a camera inspection and exact quote.
Yes. The crown sheds water from the chimney top, but the flue opening remains exposed. Rain enters the flue directly, spalling tiles, rusting dampers, and saturating the smoke chamber. A cap covers the flue while letting exhaust escape. In Huntington’s climate - with nor’easter rain and wind patterns that drive water horizontally - a crown without a cap is only half protected. We install both as a system. Call (631) 776-4075 for sizing and pricing.
For Huntington homeowners burning wood as primary heat, we recommend inspection and sweeping every cord of wood burned, or annually at minimum - whichever comes first. Heavy creosote loading is common in our rural and semi-rural properties, and the North Shore’s cooler, damper shoulder seasons create ideal conditions for third-degree creosote formation. The chimney cap and crown condition directly affects this: a cracked crown or missing cap lets water into the flue, which combines with creosote to form corrosive acids that deteriorate liners faster. We bundle cap, crown, and liner inspection with every sweep. Call (631) 776-4075 to book before burning season.
Salt air. Standard Type N mortar that holds up for 20+ years in central Suffolk can be eaten to near-void joints within 8-10 years on Centerport and Lloyd Harbor waterfront stacks. We’ve seen it repeatedly. The previous contractor likely used an inland-spec mortar without accounting for marine exposure. We repoint with a salt-resistant mix formulated for coastal conditions, and we always inspect the cap and crown as part of that repair - because failed crown drainage is what keeps those joints wet and accelerates the salt attack. Call (631) 776-4075 - we’ll show you photos of what we find.
