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 Hewlett, NY | Top Hat Chimney
We’re Top Hat Chimney, and we provide independent Gelco chimney cleaning and repair across Hewlett, NY. The quick version: we’re not a Gelco dealer and we don’t work for them, which means the only thing we’re obligated to is what we see inside your flue. In Hewlett, that usually means Gelco terra-cotta liners and stainless caps that have been fighting Jamaica Bay salt air for 60-plus years. If it’s clean, we’ll tell you it’s clean. If it’s not, we’ll show you the camera footage and explain exactly what needs doing and what can wait. Call (516) 604-2573 for a free estimate.

Why Hewlett Residents Choose Us for Gelco Service
Wendell Pike started Top Hat Chimney in 1999, and he’s spent the better part of his career working the South Shore from the Five Towns outward. He knows which Hewlett homes still have original clay tile liners from the Eisenhower era and which ones were patched one too many times after Hurricane Sandy. When we work on a Gelco system, we’ve worked on hundreds like it before. And because we’re independent, there’s no factory push to sell you a part you don’t need. We carry original Gelco replacement components when they’re available, and when a part’s discontinued, we source aftermarket equivalents cut to Gelco specs. We also quote before the first tool comes off the truck. The number you hear on the phone is the number on the invoice. You can reach a live person at (516) 604-2573 any hour, and there’s a good chance it’s Wendell himself picking up.
Common Gelco Chimney Cleaning Problems We Solve in Hewlett
- Cracked Gelco terra-cotta flue liners from freeze-thaw and salt. Hewlett sits within a half-mile of Jamaica Bay, and the southeasterly winds carry salt spray into every exposed chimney stack. Hairline cracks in clay liners widen season after season until they’re venting into the walls instead of up the flue.
- Warped or corroded Gelco stainless steel caps. Nor’easters drive salt-laden rain straight at cap assemblies. The stainless holds up better than plain steel, but after ten or fifteen years, we regularly pull caps in Hewlett that are pitted, warped, or hanging half off the flue, letting in rain, debris, and birds.
- Deteriorated mortar joints around Gelco liner sections. The same coastal humidity that spalls brick also eats the mortar between terra-cotta liner pieces. We see joints in Hewlett where you can slide a quarter through the gap. That’s a venting path, not a seam.
- Failed Gelco damper assemblies after oil-to-gas conversions. A lot of Hewlett’s post-war Capes and split-levels converted from oil to gas fifteen or twenty years ago. The original cast-iron dampers were never sized for that change, and we routinely find them rusted open or broken off entirely. That’s a cold draft all winter and a CO risk if the flue isn’t relined for the gas appliance.
- Spalling clay liner surface in older Hewlett homes. On a split-level off Piermont Avenue, our crew pulled a cracked Gelco terra-cotta flue liner from a 1963 home where the clay had spalled in sheets from decades of salt fog. A gel-coat patch would have failed within two seasons, so we relined the entire flue with a code-compliant stainless steel insert and rebuilt the crown, and the homeowner had never realized the original liner was already failing at the first tile joint.
Gelco Service in Hewlett: What Local Conditions Mean for Your Equipment
Here’s the thing that makes Hewlett different from the towns a few miles inland: the salt. Woodmere sits barely two miles north, but its chimneys don’t take the same beating because the prevailing winds off Jamaica Bay lose their punch by the time they reach that far inland. In Hewlett, southeasterly winds carry salt spray into every masonry chimney, and over decades, Gelco terra-cotta liners develop surface spalls and micro-cracks at roughly twice the rate we see in Woodmere. That’s why our Level 2 camera inspections in Hewlett look specifically for salt-induced liner erosion before a cleaning ever begins. We’re not just sweeping soot. We’re checking whether the flue is still sound enough to sweep safely. A cleaning in Hewlett should never be just a cleaning, because the environment here is doing real structural work on your liner every season, whether you burn or not.
Gelco Models & Products We Service in Hewlett
We work on the full Gelco lineup you’re likely to find in a Hewlett chimney: Gelco terra-cotta flue liners, Gelco stainless steel chimney caps, and Gelco multi-flue cap systems, the kind you see on the wider center-hall Colonials that span two flues. For repairs, we only install original Gelco replacement components when they’re available, particularly terra-cotta liner sections and caps, because the dimensions and materials have to match exactly for safe venting. When a specific Gelco part has been discontinued, we use proven aftermarket equivalents sized to Gelco specs, and we’ll tell you plainly if a reline or rebuild makes more sense than a patch. We keep common Gelco-size liner sections and cap hardware stocked locally, which means faster turnaround for Hewlett jobs, and you can learn more about our wider work with the brand on our Gelco sales & service page.

FAQs - Gelco Chimney Cleaning in Hewlett
Because salt air here has likely done more than you can see from the rooftop. A Level 2 inspection uses a camera to check the full interior of the flue for cracked terra-cotta sections, deteriorated mortar joints, and hidden voids that a basic sweep would miss. In Hewlett, we run this before every first-time Gelco cleaning, and the footage is yours to keep. Call (516) 604-2573 to schedule yours.
Sometimes, yes, if it’s an upper course and the rest of the liner is sound. But with Hewlett’s salt exposure, a single visible crack often means more sections are spalling inside that we can’t see until the camera goes down. We’ll show you the footage and give you an honest options list: section repair, full reline, or letting it ride for another season if it’s safe. Call (516) 604-2573 for a free inspection.
Usually, yes. An oil-to-gas conversion in Hewlett leaves an oversized masonry flue that’s both a New York State code issue and a carbon monoxide risk, because gas exhaust cools too fast in the bigger space and stalls inside the chimney. The fix is properly sized stainless steel insert liner, not just a damper swap. Call (516) 604-2573 and we’ll inspect what you’ve got.
Once a year, burn or no burn. Salt-driven spalling and mortar erosion continue even when the fireplace is idle, and an annual sweep with a camera inspection catches liner damage before it becomes a venting hazard or a chimney fire. For a house near the water, this is the minimum. Call (516) 604-2573 to get on the schedule.
Yes. The combination of salt spray and nor’easter-driven rain corrodes cap assemblies measurably faster in Hewlett than in inland towns. We replace more Gelco stainless caps here per chimney than anywhere else we work on the South Shore. Call (516) 604-2573 and we’ll check yours during the annual sweep.
