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 working Massapequa’s postwar neighborhoods for decades. Our crews know the tight lot lines off Sunrise Highway, the split-levels along Merrick Road, and the Cape Cods tucked between them. Dispatch is coordinated from our New York City office, but the trucks that roll up your driveway are stocked for Massapequa’s specific problems: salt-corroded caps from Great South Bay exposure, Sandy-era emergency repairs now failing, and shared flues in attached homes that need careful isolation. We don’t guess at what your chimney needs. We scope it, photograph it, and show you.
Why Hearthstone Chimney Co. Is Massapequa’s Preferred Chimney Cap & Crown Company
Massapequa homeowners call us because we’ve earned a reputation for plain talk and work that lasts. Our 90-Day Done Right Promise is backed in writing with no arguing - if it’s not right, we come back. No paperwork shuffle. No voicemail maze.
A live person answers every call, 24 hours a day, 7 days a week. Not a callback queue. Not an app. When you’re staring at a crumbling crown after a nor’easter, that matters.
Our technicians are background-checked and uniformed, and most cap and crown jobs in Massapequa finish in one visit. We carry professional-grade materials from Olympia Chimney, Famco, and Copperfield on the truck, so we’re not ordering parts while water keeps getting in.
We know the local housing stock: 60- to 80-year-old full-height brick masonry chimneys, original clay flue tiles, and the shared stacks that run through attached Capes and split-levels. That knowledge saves time and prevents the kind of half-fix that fails the next season.
Our Chimney Cap & Crown Services in Massapequa
Cap Installation
New cap installation in Massapequa runs $280-$520 for a standard single-flue stainless steel unit, with multi-flue caps for shared stacks ranging $420-$780. We size for your flue count, draft requirements, and the wind exposure your roof gets off the bay. Every installation includes a Level-2 camera inspection so we confirm the flue is sound before we seal it. Photos you can see, a plain-English verdict.
Cap Replacement
On the near-bay blocks south of Merrick Road, Sandy’s storm surge and wind stripped or corroded original masonry chimney caps outright, so a large share of Massapequa homes still vent an open, uncapped flue - a condition inland Long Island neighborhoods hit by wind alone rarely show. Cap replacement is our most common call here. We remove what’s left of the corroded unit, inspect the flue for debris or nesting material, and set a proper replacement with correct overhang and mesh screening. Most replacements finish in two to three hours. A square deal: no surprises on the bill.
Crown Repair
Massapequa’s original 1950s-60s brick crowns crack and spall under salt-laden onshore air, letting water into the flue and smoke chamber. Crown repair starts with grinding out damaged material, then rebuilding with proper slope and overhang to shed water away from the masonry. For crowns with moderate deterioration, we’ll apply a professional-grade coating as part of the repair. For crowns too far gone, we rebuild. Either way, you get photos before and after, and a written scope.
Crown Coating
Crown coating with Gelco or HeatShield products runs $340-$580 in Massapequa and adds 10-15 years of protection to a structurally sound crown. We don’t coat over active cracks or spalling - that just traps moisture. We prep the surface, address minor defects, then apply a flexible, waterproof membrane that breathes with freeze-thaw cycles. This is the right fix for crowns showing early wear but still structurally intact. Done right - and we stand behind it.
Multi-Flue Cap
Shared stacks in Massapequa’s tightly packed Capes and split-levels draw cross-contamination when one appliance vents into a flue the neighbor’s exhaust shares. A multi-flue cap isolates each flue outlet while protecting the entire crown footprint from water intrusion. We measure on-site, fabricate to fit, and verify each flue drafts independently before we leave. This is not a one-size-fits-all product. It is engineered for your specific stack configuration.
Custom Cap
Non-standard flue sizes, decorative requirements, or historic preservation needs get a custom cap measured and fabricated to specification. We work with Copperfield and Famco for specialty orders, with typical lead times of 5-7 business days. Custom caps in Massapequa generally start at $620.

Common Chimney Cap & Crown Problems We See in Massapequa Homes
- Missing caps from Sandy-era damage. Technicians working the streets south of Merrick Road routinely find chimney caps corroded through or missing entirely, a direct legacy of Sandy storm surge and wind damage. Homeowners often don’t realize the cap was lost until a sweep scopes the flue and finds nesting debris or visible sky where the cap once sat.
- Salt-driven crown erosion. The Great South Bay and Atlantic exposure deliver consistent onshore winds carrying salt particulates that chemically attack mortar joints and accelerate rust on dampers, caps, and liner brackets. Crowns that might last 25 years inland show failure in 12-15 here.
- Shared-stack cross-contamination. In Massapequa’s dense postwar housing, adjacent properties often vent through a common masonry stack. When one flue lacks a cap or has a failed crown, exhaust can migrate between units. We isolate these with multi-flue caps and verify draft separation with camera inspection.
- Sandy emergency repairs now failing. The emergency caps and flashings installed in October 2012 and the years immediately after were often temporary-grade materials. Now 10-plus years old, they’re corroded through or missing entirely, letting rain, animals, and nesting debris straight into an open flue.

FAQs - Chimney Cap & Crown in Massapequa
Salt-laden onshore air from the Great South Bay accelerates mortar joint erosion and concrete spalling far faster than inland conditions. The salt crystals draw moisture into the crown material, then expand with freeze-thaw cycles through winter. A proper crown coating or rebuild with professional-grade materials, plus correct slope and overhang, is the fix that lasts. Call (516) 614-4632 for an exact quote - estimates are free.
Yes. Shared stacks without isolated flue outlets risk cross-contamination between units, especially when one cap is missing or damaged. A multi-flue cap maintains separation while protecting the entire crown. We verify each flue drafts independently with camera inspection before we leave. Call (516) 614-4632 for an exact quote - estimates are free.
You might not, until water stains appear on the ceiling near the fireplace or you hear animals in the flue. The sure check is a camera inspection: we scope the flue and look for visible sky, nesting debris, or rust streaks on the flue tiles. On a split-level off Merrick Road just a few streets up from the bay, our Chimney Cap & Crown tech scoped the flue and found no cap at all - the storm had taken it and sky was visible past a crumbling crown. We set a new multi-flue cap over the shared stack, ground out the spalled crown, and finished it with a Gelco crown coating, then re-sealed the flashing while in the flue we pulled a raccoon nest the open stack had allowed. On the adjoining flue we confirmed the neighbor’s appliance was drafting cleanly so the two vents stayed isolated the way they should. Call (516) 614-4632 for an exact quote - estimates are free.
Yes. Sporadic use actually increases risk because damp coastal air combines with residual soot to form acidic compounds that deteriorate flue tiles and metal components. The same coastal exposure means nor’easters deposit heavy wet creosote loads in fireplaces that see sporadic use, making annual cleaning critical before each heating season. And an open or damaged cap lets rain and animals in year-round, whether you burn or not. Call (516) 614-4632 for an exact quote - estimates are free.
No. Paint traps moisture underneath and accelerates the freeze-thaw damage that’s already spalling the surface. Crown coating is not paint - it’s a flexible, breathable membrane applied to properly prepared concrete. We grind out loose material, address the underlying cracks, then apply Gelco or HeatShield products designed for this specific application. Anything less is a temporary cover-up that fails within a season or two. Call (516) 614-4632 for an exact quote - estimates are free.
