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 Greenburgh
A chimney cap replacement in Greenburgh typically costs $380-$690 for a standard single-flue galvanized cap, while a full custom multi-flue cap with installation runs $1,200-$2,300 depending on crown dimensions and material. Crown repair work, including crack sealing and resurfacing with a polymer coating, lands between $450 and $1,100. The older the chimney, the more likely the crown has already begun to fail, and in Greenburgh’s split housing stock, age hits different neighborhoods differently. Our crews work across every part of town, from the river villages to the Hartsdale side streets, and we bring a camera down every flue before we quote a dollar of cap or crown work. Call (980) 580-8641 and you’ll get a written price before any work starts, not after.
Why Emberly Chimney Cleaners Is Greenburgh’s Preferred Chimney Cap & Crown Company
We’ve cleaned and inspected more than 38,000 chimneys since 2009, and Greenburgh keeps our techs busier than most towns because the housing stock demands it. Every job carries the Haven Standard: written price, written scope, written warranty, all delivered before a single tool comes off the truck. Clause 4 of that standard requires a camera-scan inspection and full photo record on every visit, a practice we made standard in 2009, years before inspectors or insurers asked for it. What that means in Greenburgh is simple: if a cap looks rusted but the liner is fine, we’ll show you the footage. If a crown looks cracked but the flue is still solid, we’ll show you that too. Then we quote the work, in writing, and you decide.
Corrine Halstead, who leads our Chimney Cap & Crown team, insists on one thing: no homeowner in Greenburgh gets a recommendation they can’t verify. Not by taking our word for it, but by watching the camera scan themselves. That’s the whole point of the inspection. Dispatch and scheduling run through our New York City office, but the crews working your street know the difference between an Edgemont colonial and an Irvington Victorian without asking for directions.
Our Chimney Cap & Crown Services in Greenburgh
Cap Installation
A missing cap on a Greenburgh chimney lets rain, snow, and the occasional squirrel straight into the flue. In the postwar capes and colonials around Hartsdale, we regularly install Famco single-flue caps sized correctly to the existing clay tile, not the old oil flue opening. A standard galvanized cap install runs $380-$560; stainless runs $510-$780. Each one gets sealed at the mounting band and photographed before we leave.
Cap Replacement
Rust never sleeps in Greenburgh’s damp river air. Caps on homes in Hastings-on-Hudson and Tarrytown corrode faster than inland homes because airborne moisture settles into every seam. When a cap has rusted through at the band, we replace it and check whether the flue opening was oversized for the current appliance. If it was, the new cap gets sized to the actual venting, not the original clay tile. Replacement runs $420-$690 for standard caps, more for custom work.
Crown Repair
A crown is the concrete slab at the top of the chimney, and in Greenburgh it’s the single most common failure point we see. Freeze-thaw cycles force hairline cracks open year after year, especially on west-facing elevations where river wind drives moisture into the mortar. Left alone, water enters the smoke chamber and firebox. Crown repair usually runs $450-$950, and we’ll know the extent only after the camera scan shows what’s happening below the roofline.
Crown Coating
For crowns that haven’t structurally failed but show hairline cracking, we apply a HeatShield crown coating that seals the surface and flexes with temperature swings. In Greenburgh’s river villages, where damp air and hard freezes repeat every winter, this coating typically extends crown life by a decade or more. Coating alone runs $550-$1,100 depending on crown size and prep work. We can’t know if a coating will do the job until we’ve seen the crown up close and the flue on camera.

We stock parts from Famco, Copperfield, and HeatShield specifically because they hold up to Greenburgh’s conditions. Famco caps carry thick galvanized coating that resists river-air corrosion better than thin-box replacements. Copperfield multi-flue caps are our go-to for older masonry chimneys with irregular crown shapes, common in the bigger Victorians along the river. HeatShield’s crown coating system handles the freeze-thaw stress that wrecks ordinary mortar patches. When we install any of these, you get the manufacturer’s warranty plus our 365-Day Done Right Promise stamped on the job.
Common Chimney Cap & Crown Problems We See in Greenburgh Homes
- West-facing river-village crowns with hairline cracks. Homes in Irvington, Hastings-on-Hudson, and Tarrytown with west-facing chimneys take the brunt of Hudson River wind and moisture. Cracks open in November, freeze in January, and widen with every cycle. Water reaches the smoke chamber, and the homeowner sees staining on the ceiling below.
- Rusted mounting bands on Hartsdale and Edgemont caps. Postwar caps were sized for oil heating flues. When the home converted to gas in the 1990s or 2000s, nobody resized the cap. The band rusts, rain slips through the oversized opening, and the clay liner begins saturating with acidic condensate.
- Missing or undersized caps on converted gas flues. Gas appliances need precise venting. A cap that’s too loose or too tight changes draft, and a missing cap invites downdrafts that push acidic moisture back down into the clay tile. Inside a chimney that looks fine from the street, the liner may already be flaking apart.
- Spalling brick below failed crowns. Once a crown stops shedding water, the top two or three courses of brick start absorbing it. In Greenburgh’s freeze-thaw cycle, that means brick faces pop off by spring. We document this with photos and show you exactly where the failure began.

FAQs - Chimney Cap & Crown in Greenburgh
River-village chimneys in Greenburgh need crown coating more often because they sit in damp Hudson River air that wicks into hairline cracks, then hard freeze-thaw cycles every winter force those cracks wider. Homes in Irvington, Hastings-on-Hudson, and Tarrytown face more moisture than inland Hartsdale houses, so crowns on west-facing elevations degrade faster. Coating fills and seals those micro-cracks before they reach the point of structural repair. If you’re seeing white mineral streaks staining the brick below the crown, that’s water already working through. Call (980) 580-8641 and we’ll camera-scan the flue to see how far it’s traveled.
You need a camera inspection before anyone can answer that honestly. When a Hartsdale or Edgemont home converted from oil to gas, the existing clay flue was often left oversize for the smaller gas boiler. The gas exhaust condenses on the cold clay walls as acidic moisture, which eats the liner from the inside. A rusted cap is a symptom, but the liner condition beneath it determines whether you need only a new cap or a cap plus a stainless relining. We’ll show you the footage inside the flue first, then give you a written price for exactly what’s needed, nothing more.
NFPA 211, the national standard for chimneys, says every flue needs a properly sized cap with spark arrestor mesh, and the crown must shed water away from the flue walls. Greenburgh’s freeze-thaw climate makes crown integrity more critical here than in dryer regions, because cracked crowns start brick failure within a couple seasons. Our Level 2 inspection defaults to NFPA 211 standards, camera down the flue, and we document everything for your records, per Clause 4 of the Haven Standard.
You know because we show you. Before we quote any crown work, we document it: photos of the crown surface, camera footage inside the flue showing whether water has reached the smoke chamber, and a written description of exactly which cracks are structural and which are cosmetic. If a crack is hairline and hasn’t penetrated, we’ll say so and recommend coating. If water is actively entering, you’ll see the staining on camera. Homeowners in Greenburgh who’ve been told by other companies that they need thousands in crown work regularly bring us those estimates, and our Free Second Opinion tells them what the camera shows instead.
Yes, a custom multi-flue cap can fix the downdraft problem on a Greenburgh chimney serving both a fireplace and a boiler, provided the downdraft is caused by cap configuration rather than liner or crown failure. On older Greenburgh homes with masonry fireplaces and gas boilers sharing one stack, the two flues need separate, correctly sized terminations. A Copperfield custom multi-flue cap fabricated to the crown’s actual dimensions gives each flue its own opening and mesh. The camera scan tells us whether that’s the whole fix or whether the liner also needs attention. Call (980) 580-8641 for a written quote, camera footage included.
Our inspection covers the cap, crown, flue liner, smoke chamber, and firebox, all documented with camera footage and still photos. In Greenburgh, where two different chimney eras sit ten minutes apart, we check for failure modes specific to each: spalling and crown cracks in the river villages, rusted caps and acidic condensate damage in postwar Hartsdale and Edgemont homes. You get the footage and the written report before any quote, so the recommendation is based on evidence on screen, not a technician’s opinion from the driveway.
