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.
Gelco Chimney Cleaning in New York, NY | Level Two Chimney New York
We provide independent Gelco chimney cleaning and repair across New York, from Bedford-Stuyvesant brownstones to Park Slope co-ops. What makes our Gelco work different here: decades of oil-heat soot, coastal freeze-thaw cycling, and city-mandated Clean Heat fuel conversions all hit Gelco terra-cotta liners and cast-iron dampers harder than anywhere else in the region. Call (551) 213-5548 for a written price before any work starts.

We’re not manufacturer-affiliated or authorized. We’re independent, which means we replace only what actually fails, and every job includes a documented photo record under Clause 4 of the Haven Standard.
Why New York Residents Choose Us for Gelco Service
Corrine Halstead, our owner, grew up in the Bronx and has spent nearly two decades cleaning and inspecting chimneys across New York City. She learned the technical side of the trade through the building trades and construction technology program at Bronx Community College, and she still reads every flue liner the same way: name the condition, state the number, write the price.
Our technicians are factory-familiar with Gelco’s terra-cotta flue liners and cast-iron damper housings through thousands of New York service calls. That matters when a Gelco 8×13 liner tile has spalled inside a flue that hasn’t been opened since the Reagan administration. We know what these parts look like when they fail, and we know what it costs to fix them properly. For broader Gelco sales & service work, we keep Gelco-compatible stainless steel caps, cast-in-place liner alternatives, and heavy-duty damper hardware matched to original dimensions in local stock.
We show you the camera footage before we quote anything. Clause 4 of the Haven Standard requires a photo record on every job, and we’ve done that continuously since 2009.
Common Gelco Chimney Cleaning Problems We Solve in New York

- Frost-spalled Gelco terra-cotta liner tiles. Repeated freeze-thaw cycles from New York’s November-to-March cold snaps crack Gelco clay tiles at the mortar joints. Clay shards drop into the flue, block the draft, and smoke backs up into the parlor. We remove the broken tile, vacuum the debris, and reline with stainless steel when the damage is structural.
- Seized Gelco cast-iron dampers. Decades of oil-heat sulfur deposits plus coastal humidity leave Gelco damper housings frozen open or closed. An open damper is a permanent draft path that costs you heat. A closed one is a board-flagged safety hazard. We free or replace the damper hardware, depending on what the camera shows.
- Acidic condensate damage from gas conversions. High-efficiency gas boilers produce acidic condensate that eats Gelco clay liners in pre-1940 tenements installed with minimal clearance. Where NYC’s Clean Heat program has forced fuel conversion, we routinely find liners that need resurfacing or full replacement before the gas appliance can operate safely.
- Corroded Gelco multi-flue cap bases. Salt-laden nor’easter rain corrodes galvanized cap bases at the mounting flange. The cap loosens, water gets in, and animals follow. We replace with Gelco-compatible stainless steel caps that hold up to coastal exposure.
- Creosote and petroleum soot buildup in multi-flue buildings. A single Gelco chimney serving four to six apartment flues accumulates dense petroleum soot from oil heat plus creosote from fireplaces. We clean all flues in the stack, not just the one that smokes.

AfterGelco Service in New York: What Local Conditions Mean for Your Equipment
Here’s what’s genuinely different about New York: in co-op and condo buildings, a single Gelco chimney serving multiple apartments is a shared building system controlled by a board or management company. A Local Law 11 facade inspection that flags a deteriorated Gelco multi-flue cap or spalling liner triggers a building-wide chimney remediation contract, not an individual homeowner repair. One inspection note becomes a fifty-unit project. Property managers and co-op boards are the ones who make that call, and they need a written scope, a written price, and a documented photo record before they’ll bring it to a board meeting. That’s exactly what we deliver. For building managers reviewing New York service area coverage, we provide one point of contact for multi-flue stacks across a portfolio.
Last month our crew was called to a Park Slope brownstone on Eighth Avenue after a tenant reported smoke backing into a parlor-level fireplace. We pulled a cracked Gelco 8×13 terra-cotta liner tile that had spalled during the January nor’easter, leaving a flue obstruction. We removed the broken tile, vacuumed a half-bushel of creosote and clay fragments, and installed a custom stainless steel relining system with a new Gelco-compatible top-mount damper. The system now drafts clean on all four flues, and the co-op board has scheduled pre-season sweeps for the whole block.
Gelco Models & Products We Service in New York

We service the full range of Gelco products common in New York’s pre-war housing stock: the Gelco 8×13 Rectangular Terra-Cotta Flue Liner, the Gelco 10×10 Square Terra-Cotta Flue Liner, Gelco Cast-Iron Top-Mount Dampers, and Gelco Stainless Steel Multi-Flue Caps. True OEM clay liners from decades-old Gelco stocks are often not economical to source, so we stock Gelco-compatible stainless steel caps and heavy-duty damper hardware matched to original dimensions. We resurface or reline rather than replace structurally sound chimneys, but we recommend full replacement of shattered clay liners or seized dampers when repair would not last another New York winter.

FAQs - Gelco Chimney Cleaning in New York
Yes, in most cases. NYC’s Clean Heat program forced thousands of pre-war buildings off #4 and #6 heating oil, and those century-old masonry flues are caked with petroleum soot that must be removed before a gas appliance can safely vent. More importantly, high-efficiency gas boilers produce acidic condensate that deteriorates Gelco clay liners that were never designed for it. We camera-scan the flue, document the liner condition, and give you a written recommendation. If relining is needed, you’ll see the photos that prove it. Call (551) 213-5548 for a written quote.
Gelco clay liners from decades-old stocks are often not economical to source, and in many cases the manufacturer’s original production has been discontinued or scaled back. We stock Gelco-compatible stainless steel caps, cast-in-place liner alternatives, and heavy-duty damper hardware matched to original dimensions. If your existing Gelco clay liner is structurally sound, we resurface rather than replace. If it’s shattered, stainless steel is the long-term fix. The camera footage tells you which one you need.
The galvanized base on Gelco multi-flue caps corrodes at the mounting flange under constant salt-laden rain, loosening the cap and letting water in around the base. We replace with Gelco-compatible stainless steel caps that hold up to coastal exposure. A leaking cap base is a $650 to $1,400 fix; a water-damaged flue liner left unchecked is a much bigger number.
All of them. A Brooklyn brownstone chimney stack typically contains four to six individual flues serving separate apartments, and decades of oil-heat soot plus fireplace creosote accumulate across the whole stack. Cleaning only the smoking flue leaves the others as fire hazards. We clean and camera-scan the entire stack in one visit, and the board gets a photo record for every flue. Call (551) 213-5548 for a flat-price sweep across the whole chimney.
It means the board has a compliance deadline and a board meeting coming up. An FDNY deficiency notice or a Local Law 11 facade report flagging a deteriorated Gelco cap or spalling liner triggers a building-wide remediation contract. We provide the written scope, written price, and documented photo record boards need to approve work. The camera doesn’t argue with you, and neither does the price sheet.
