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 City Island, NY | Hadley Chimney Yonkers
We provide independent Gelco chimney cleaning and repair across City Island, NY, from Belden Point to the City Island Bridge. We’re not a Gelco factory service center and we don’t claim to be, but our techs have serviced enough Gelco dampers, caps, and chase covers on this island to know exactly how salt air and osprey nesting pressure stress these components. Call (914) 233-3156 for a written quote before any work begins, and you’ll get a live person on the phone, not a callback queue.
Why City Island Residents Choose Us for Gelco Service
Cory Mitchell, our owner, learned the trade at Los Angeles Trade-Technical College before bringing that training east, and he’s been up on enough City Island roofs doing Chimney Sweep in City Island work to recognize the specific ways Gelco hardware fails here. A Gelco damper that works fine in Riverdale can seize within two seasons on City Island because the salt spray off Long Island Sound gets into everything. We use aftermarket parts that match or exceed Gelco’s original specs, because OEM components for older models are often backordered for weeks. When we quote a damper repair or cap replacement on City Island, we hand you a written price before anything gets touched, and our techs text you photos from inside the firebox so you see what we see. No guesswork, no verbal estimates that shift once the ladder goes up.
We also carry Gelco sales & service expertise across Westchester and the Bronx, so the same crew that handles a Lock-Top damper in Yonkers knows what to expect when they cross the bridge to City Island.

Common Gelco Chimney Cleaning Problems We Solve in City Island
- Seized damper pivot pins from salt-laden air. City Island’s constant exposure to Long Island Sound means airborne salt works its way into Gelco damper pivots within a season or two. The pin corrodes, the cable snaps or the handle jams when you try to open it before lighting a fire. We replace the pin with a stainless aftermarket version and lube the assembly so it moves freely.
- Rusting mounting brackets on Gelco multi-flue caps. Wind-driven salt spray and soot collect where the cap meets the crown, and the brackets are usually the first thing to go. On City Island, we see this happen faster than anywhere else in our service area because the island gets spray from every direction depending on the wind.
- Pinhole rust through Gelco chase covers on factory-built chimneys. After a few nor’easter seasons, galvanized chase covers develop pinholes that let water drip onto the firebox below. By the time a homeowner notices the stain on the ceiling or the rust on the damper, the cover has been compromised for months. We can patch, coat, or replace depending on what the metal still has left.
- Hardened and cracked Gelco top damper gaskets. The salt/humidity cycling on City Island repeated day after day breaks down the gasket material on Gelco top dampers. Once the seal fails, cold backdrafts push smoke into the room even when the damper is closed. We replace the gasket and test the seal before we leave.
- Osprey nests on multi-flue caps. This is the one that surprises people. Ospreys return to City Island every spring and they’ve been known to build on top of multi-flue caps, especially along the waterfront streets. The weight of a nest can bend the cap’s mesh and block airflow. We remove the nest carefully during a cleaning, check the cap for damage, and recommend a deterrent if the birds keep coming back to the same chimney.
Gelco Service in City Island: What Local Conditions Mean for Your Equipment
City Island is the only neighborhood in the Bronx where a Gelco chimney service call routinely includes checking for osprey nests built on top of multi-flue caps. The raptors return to the same chimney each spring, and their nests are heavy enough to bend the cap’s mesh and restrict the draft. Combine that with the island’s unusual concentration of 19th-century Victorian homes with narrow flues and original lime mortar, and you have a recipe for smoke backing up into living rooms even when the chimney was swept six months ago. Our techs know to check the cap before assuming the flue itself is clogged, because on City Island, the cap is frequently the problem. The freeze-thaw cycles also crack old clay tile liners, and when a nor’easter drives rain horizontally into a partially lined flue, the water mixes with creosote and creates a corrosive slurry that accelerates liner deterioration. For Gelco damper owners, that means checking the pivot assembly every cleaning, not just when the cable breaks.
Gelco Models & Products We Service in City Island
We service the Gelco Standard Top Damper, the Lock-Top Damper, Gelco Multi-Flue Caps, and Gelco Chase Covers. Most of what we stock for these models is high-quality aftermarket: stainless pivot pins, replacement gaskets, coated chase covers, and multi-flue cap mesh that matches the original dimensions. Gelco OEM parts for older models are tough to source quickly, and our stance is simple: repair rather than replace whenever the metal and mounting hardware are still structurally sound. If the chase cover has pinholes but the structural frame is fine, we coat it. If the damper cable snapped at the pivot but the damper plate itself is solid, we replace the pin and cable, not the whole assembly. That approach saves City Island homeowners real money without cutting corners.

FAQs – Gelco Chimney Cleaning in City Island
Because salt-laden air is seizing the pivot pin whether or not you use the damper. The corrosion happens continuously, and one day the cable simply can’t take the tension anymore. We replace the pin with stainless and reset the cable tension. Call us at (914) 233-3156 if you hear grinding or feel resistance at the lever. Don’t force it.
Yes. We remove the cap carefully, clean the flues, and then deal with the cap itself. If the mounting brackets are rusted through, we replace the brackets or the whole cap through our Chimney Repair in City Island. If the mesh is bent from an osprey nest, we straighten or replace it. The cleaning never waits on the cap decision; we do both in the same visit.
We do, and on City Island we see this all the time. Many Victorian-era chimneys here still have original clay tile liners with cracked sections. We inspect the tiles during the cleaning, note any damage, and tell you plainly whether the liner is safe to use or needs repair. The Gelco damper work proceeds as normal unless the flue itself is unsafe.
Salt air accelerates galvanic corrosion on galvanized steel, which is why Gelco chase covers on City Island develop pinholes faster than inland. Once pinholes form, water drips onto the firebox and rusts the damper. We can coat the cover if the metal still has structural integrity, or replace it with a stainless or coated version if it’s too far gone. Call (914) 233-3156 and we’ll assess it with photos.
No. A nest blocks airflow, which pushes carbon monoxide back into the house and creates a fire hazard from hot embers reaching the nest material. We remove the nest, check the cap for damage, and recommend a deterrent before you fire up again. If you suspect a nest, don’t light anything until we’ve looked at it. Call (914) 233-3156.
