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 Greenpoint
Chimney cap and crown work in Greenpoint runs $340-$1,100 for most row house and tenement chimneys, with multi-flue custom caps on the upper end. The real question isn’t the price, it’s whether the crown and cap are handling the moisture and gas-appliance exhaust this neighborhood throws at them. Wendell and his crew know Greenpoint’s attached brick stacks better than any franchise that rotates through with a pressure washer and a pamphlet. Call (929) 822-6306 and you’ll talk to someone who can look at a Manhattan Avenue roofline from the sidewalk and already know what’s going on up there.
Why Top Hat Chimney Is Greenpoint’s Preferred Chimney Cap & Crown Company
Wendell Pike founded Top Hat Chimney in 1999 and has never stopped being the guy who shows up at the door. That matters in Greenpoint because this neighborhood’s chimneys are unlike anywhere else in Brooklyn. The attached brick row houses and tenements on streets like Greenpoint Avenue, Franklin Street, and Norman Avenue were built between the 1880s and 1920s. Their chimney stacks were designed for coal furnaces and open fireplaces, then converted to gas decades ago. The flues are now oversized, damp, and often partially sealed off. A sweep who only knows suburban single-flue chimneys will miss half of what’s happening up there. Wendell has been in more of these stacks than he can count, and the camera footage comes down with a plain-English verdict every time, no exceptions.
We answer the phone with a live person around the clock. That may well be Wendell picking up at 7 a.m. when you call from Greenpoint before work. No call center, no voicemail box, no “press 2 for scheduling.” And every job is backed by the 90-Day Done Right Promise in writing. If something isn’t right, one call brings the crew back at no additional cost. Greenpoint homeowners don’t need to take our word for it either. Ask anyone on your street.
Our Chimney Cap & Crown Services in Greenpoint
Cap Installation
A new cap on a Greenpoint chimney does two jobs. It keeps rain, pigeons, and leaves out of the flue, and it manages the draft from gas boilers and water heaters that were never meant to run through a Victorian-era 9×13 clay tile. We stock standard sizes and we fit stainless steel caps with proper screening so the local pigeon population stops treating your flue like rent-controlled housing.
Cap Replacement
The old cap on most Greenpoint row houses was put on when the gas conversion happened, which is often 20-30 years ago now. Moisture-heavy appliance exhaust and East River air corrode those caps from underneath while the Newtown Creek humidity eats the fasteners from above. We replace them with stainless or copper, sized to the actual flue dimensions, not the “close enough” we find up there all the time.
Crown Repair
The crown is the concrete cap that seals the top of the chimney structure itself. In Greenpoint, crown mortar joints spall faster than interior Brooklyn because the peninsula sits between the East River to the west and Newtown Creek to the south. Moisture gets into the crown, freezes in winter, and pops the joints apart. We rebuild crowns with the right slope and overhang so water sheds instead of pooling against the flue tiles.
Crown Coating
A Gelco crown coat can buy ten to fifteen years on a crown that’s weathered but still structurally sound. We tuck-point loose joints first, then brush and seal the whole crown surface. For Greenpoint’s pre-war stacks, this is often the difference between a $600 coating and a $2,800 rebuild. The camera tells us which one you actually need.

Trusted Brands We Service in Greenpoint
We install and service caps, crowns, and liners from Copperfield, HeatShield, and Gelco. These aren’t big-box shelf brands. They’re what we’ve used for years because they hold up on coastal-exposed brick the way cheaper hardware-store caps do not. For Greenpoint’s multi-flue tenement stacks, we keep common Copperfield and Gelco components ready so a cap replacement doesn’t mean two weeks of waiting on a distributor. When a row house needs a new crown and cap before the rain pulls through, waiting isn’t the answer.
Common Chimney Cap & Crown Problems We See in Greenpoint Homes
- Sealed-off flues packed with pigeon nests. Original Greenpoint row house chimneys were built with three or four flues serving a furnace, parlor fireplace, upper fireplaces, and a kitchen range. Gut renovations sealed most of them, but the flues were never capped. Pigeons move in, nests build up, and the trapped moisture migrates into the shared party wall between you and your neighbor.
- Crown mortar joints spalling from coastal humidity. The East River and Newtown Creek keep ambient moisture high year-round. Mortar absorbs it, freezes in winter, and the crown erodes a quarter inch at a time. We see crowns on 1905-era Franklin Street townhouses that have lost an inch of mortar in a decade.
- Metal caps corroding prematurely from gas-appliance exhaust. Gas boilers put out cooler, wetter exhaust than coal or wood. That moisture condenses on the underside of a metal cap and corrodes it from the inside out, even when the exterior still looks fine from the street below.
- Backdrafting in multi-family stacks. A single Greenpoint tenement chimney often serves gas appliances across several units. When flues aren’t properly capped and separated, exhaust from one apartment can push into another. It’s a layered draft problem a standard single-family sweep never sees, and it’s one of the reasons we always check the whole stack, not just one flue.

FAQs - Chimney Cap & Crown in Greenpoint
Greenpoint is a peninsula between the East River and Newtown Creek, which means stronger winds and higher ambient moisture than interior or upland Brooklyn neighborhoods. That moisture soaks into crown mortar, freezes through the winter, and pops the joints apart faster. The old industrial air quality from the creek corridor doesn’t help either. We see shortened repointing cycles all over 11222 and 11211, and it’s why an annual inspection matters more here than in a drier inland zip code. Call (929) 822-6306 for a crown check when you notice crumbling mortar on the sidewalk after a storm.
If they were sealed without being capped and screened, they become bird boxes and moisture traps. Pigeons nest in them, leaves and rain blow in, and the moisture wicks through the shared party wall into the masonry next door. We have opened sealed flues on Greenpoint Avenue row houses that were half full of old nest material and spalled clay tile. The fix is simple: cap the live flues and screen the abandoned ones so the stack can breathe without becoming a habitat. The camera footage shows you everything before we touch anything.
A multi-flue cap covers the entire top of the chimney stack with proper screening and separation between each flue. That keeps rain and pigeons out while preserving the individual draft paths for each apartment’s boiler or water heater. Without it, one unit’s exhaust can backdraft into another, and moisture from an uncapped flue can travel through the whole stack. In a three- or four-unit building, the cap is doing structural work. It’s not cosmetic. Call us for an estimate and we’ll walk you through exactly what your stack needs.
It depends on how much of the crown has already failed. If the surface is weathered but the crown is still intact with only surface checking, a Gelco coating after tuck-pointing will usually buy you 10-15 years and cost far less than a rebuild. If the crown has deep cracks, missing sections, or the flue tiles are loose, no coating will hold. We’ll tell you which one it is, with the camera footage on the screen in front of you. A full rebuild starts around $1,500 on a typical Greenpoint row house stack. Call (929) 822-6306 and we’ll give you an honest answer before any work is booked.
Your gas boiler and water heater are exactly why you need a cap. Gas exhaust is cooler and wetter than wood or coal smoke, and it condenses readily inside an uncapped oversized flue. That condensation is acidic and eats the clay tile liner from the inside out. The cap keeps rain and pigeons out, and a properly sized cap helps that cool exhaust leave the stack instead of condensing halfway up. Greenpoint’s converted Victorian flues are oversized for gas already, so a cap with the right mesh and design is doing real work, even with no fire in the fireplace. If you haven’t had the boiler flue checked in a few years, call us and we’ll take a look.
