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.

AfterGelco Chimney Cleaning in New York City, NY | Emberly Chimney Cleaners
We provide independent Gelco fireplace services in New York City, including chimney cleaning, inspection, and repair across all five boroughs. Gelco liners and caps are common in pre-war brownstones and tenements here, and they fail in ways you won’t see in the suburbs. The difference with our work is that we coordinate the multi-flue reality of New York City buildings and document everything on camera before you pay a dollar. Call (980) 580-8641 for a written estimate.
We’re not authorized by Gelco and we don’t claim to be. What we are is a team of chimney techs who’ve pulled enough failed Gelco liners out of Brooklyn flues to know exactly what goes wrong and how to fix it without wasting your money. Corrine Halstead, our owner, grew up in Inwood and has worked chimneys in every borough, from Bed-Stuy brownstones to South Bronx tenements.
Why New York City Residents Choose Us for Gelco Service
Most Gelco chimney work in New York City happens in buildings that are older than the company that made the liner. That’s not a joke. A brownstone built in 1905 was designed for coal, converted to oil, then converted again to gas. The flue that now holds a Gelco 6″ flexible stainless liner has seen three different fuels and a century of weather. We understand both halves of that equation, the Gelco hardware and the New York City stack it lives in.
Our techs are background-checked and uniformed, and every job starts with a written price and a written scope of work. Clause 1 of the Haven Standard requires that, and we’ve worked that way since 2009. If we recommend a repair, you’ll see the camera footage that supports it. Corrine herself has been known to walk a building owner through the video frame by frame, pointing out exactly what the flue walls look like before any conversation about money begins. The camera doesn’t soften what it finds. Neither do we.
You’ll also deal with a live person when you call, 24 hours a day, seven days a week. Not a voicemail, not a form. If a Gelco cap is lifting off a crown in January, we answer the phone in January.
Common Gelco Chimney Cleaning Problems We Solve in New York City
- Flexible liner kinks at 45° offsets. New York City brownstones often have multiple offset flues where the original mason angled the chimney to hit a particular roofline or avoid a structural beam. Gelco flexible liners are designed to bend, but a 45° offset combined with decades of acid condensate from gas appliances can kink the stainless wall. That kink causes smoke spillage into upper-floor units. We see it regularly in Bed-Stuy and Crown Heights.
- Multi-flue caps pulling loose from corroded crowns. Gelco’s 8″ multi-flue cap assemblies are bolted to the chimney crown. In New York City, where we get 70-80 freeze-thaw cycles per winter, the mortar under those bolts spalls and crumbles. The cap lifts, water gets in, and the whole stack deteriorates faster. Harlem and South Bronx flat-roof stacks are particularly exposed.
- Chase covers rusting at spot-welded seams. Gelco heavy-duty chase covers have welded corners, but salt air changes the math. In Bay Ridge, Red Hook, and the Rockaways, we’ve pulled chase covers that looked fine from the roof but had rust-through at the seams underneath. Water pours down into the liner and firebox every time it rains.
- Gas vent liners dislodging from appliance collars. Gelco 4″ gas vent liners can pull loose when large steam boilers cycle on, especially in older tenement systems with oversized burners. When that happens, carbon monoxide backdrafts into basement kitchens. We’ve fixed this exact problem in Bed-Stuy tenements where the original coal-to-gas conversion left a loose connection no one had touched in fifty years.
- Original unlined brick flues that were never properly fitted. A surprising number of Gelco liners in New York City were installed into brick flues that were never meant to hold a liner. Without proper insulation, the gap between the liner and the brick collects condensation, which eats the stainless from the outside in. By the time we’re called, the liner looks like lace.
BeforeAfterGelco Service in New York City: What Local Conditions Mean for Your Equipment
Here’s something specific to New York City that changes how Gelco work gets done: co-op proprietary leases almost always assign chimney maintenance to the building corporation, not the individual shareholder. That means when a Park Slope brownstone co-op calls about one fireplace smoking, the job typically becomes a six-flue inspection covering every unit’s fireplace and boiler vent. One service call, one bill to the management company, six flues documented. That workflow doesn’t exist in the suburbs, and it’s why we’ve built our entire documentation around it. Clause 4 of the Haven Standard requires a photo record on every job, and for co-op work that record goes to the board, the management company, and the shareholder. Everyone sees the same camera footage. No one argues with it.
Add the climate to that. New York City stacks rise 20 to 40 feet above flat tar roofs with zero shelter. Freeze-thaw cycles spall the brick and erode mortar joints every winter. Coastal salt air accelerates corrosion in Brooklyn and Staten Island. A Gelco liner that would last twenty years in New Jersey might fail in fifteen in Red Hook. That’s not a knock on Gelco. It’s just what the environment does.
Gelco Models & Products We Service in New York City
We work on the Gelco product lines most common in New York City buildings: the 6″ flexible stainless liner, the 8″ multi-flue cap assembly, the heavy-duty chase cover, and the 4″ gas vent liner. For liner and cap replacements, we use OEM Gelco parts because the fit inside legacy brick stacks is too precise for guesswork. For sealing and crown work, we often recommend a quality aftermarket stainless or silicone product that handles New York City’s acid-condensate environment better than the original Gelco material. We’ll tell you plainly which approach we’d take and why. If a flue serving multiple gas boilers needs a full liner replacement rather than another patch, we say so.
Gelco Service Pricing in New York City
A Gelco chimney cleaning in New York City typically runs between $200 and $400 per flue for a standard sweep and camera inspection. Multi-flue brownstone jobs that require coordination with a management company and documentation for a co-op board start around $600 and go up depending on how many flues are involved. Liner repairs with OEM Gelco parts generally run $800 to $2,500 depending on access and the extent of the damage, and full liner replacement in a six-flue brownstone can run $3,000 to $6,000. Every quote is written before work starts. You’ll see the scope, the price, and the warranty in print before our tech lifts a brush. Call (980) 580-8641 for a free estimate.

FAQs - Gelco Chimney Cleaning in New York City
Yes. We can run a camera down the flue from the roof side of a Gelco liner and get a full view of its condition without entering multiple apartments. That said, for co-op buildings where multiple units share a single masonry chimney stack, we recommend a full multi-flue inspection at some point. It’s the only way to confirm each flue is venting correctly, and it satisfies the documentation most boards want. Call (980) 580-8641 and we’ll walk you through what a single-flue inspection covers.
Freeze-thaw cycles are the culprit. New York City gets 70-80 of them per winter, and each one expands and contracts the mortar holding the cap’s bolts in place. Over a few years, the mortar fails and the cap lifts. The fix is to rebuild the crown with a proper slope and re-anchor the Gelco cap with new hardware - our Chimney Cap & Crown - New York City service handles exactly this. A cap that lifts every spring is a sign the crown underneath needs work, not just the cap itself.
Yes, it can be. A rattling Gelco gas vent liner often means it has dislodged from the appliance collar, especially in older tenement boilers that cycle hard. When the liner pulls loose, carbon monoxide can backdraft into the living space instead of venting up the flue. Treat it seriously. Call (980) 580-8641 and we’ll inspect the connection, re-secure the liner, and document it with camera footage.
In most Manhattan co-ops, yes. The proprietary lease usually assigns chimney maintenance to the building corporation, which means the board or its managing agent has to sign off before any liner work proceeds. We provide the written scope, pricing, and camera documentation they’ll want to see. Many boards approve the work faster when they can review the flue footage themselves. Call (980) 580-8641 and we’ll help you prepare the package.
Maybe. Some 1800s flues are too narrow or too offset to accept a modern Gelco liner without major reconstruction. We’ll run a camera down first and tell you what’s possible. If a Gelco liner can’t physically fit, we’ll tell you that plainly and discuss alternatives. There’s no point forcing a liner into a flue that will kink it.
