We’re not affiliated with Gelco and we don’t pretend to be. We’re the crew that’s been servicing their liners, caps, and multi-flue systems in Brooklyn Heights long enough to know where they hold up and where they don’t. If you live in the historic district, that experience matters more than most people realize.

Why Brooklyn Heights Residents Choose Us for Gelco Service

Wendell Pike started Top Hat Chimney in 1999, and he’s spent the better part of two decades on Brooklyn rooftops, from the old brownstones off Flatbush Avenue to the row houses on the quieter blocks. He learned the mechanical side at Palomar College and figured out the rest on the job. The part that stuck: tell people the truth, even when it means less work for us. If a Gelco liner just needs a seam patched, he’ll say so. If it’s shot, he’ll show you the camera footage and let you decide.

Our Brooklyn Heights calls get answered by a live person, around the clock. Often it’s Wendell himself. The price you hear on the phone is the price on the invoice, and every job carries our 90-Day Done Right Promise in writing. One call brings us back if something isn’t right. That’s the deal, no fine print.

We also stock the common Gelco sales & service parts locally, so we’re not waiting on a distributor when your cap needs a new mesh guard or your liner needs a top-plate repair. For Brooklyn Heights, that turnaround speed matters, because LPC approvals already add time to any visible exterior work.

Common Gelco Chimney Cleaning Problems We Solve in Brooklyn Heights

Here’s what we actually run into on Gelco systems in this neighborhood:

• Pitted and perforated Gelco 304 stainless liners. Brooklyn Heights sits on a bluff directly above the East River, and the salt-laden harbor wind eats 304 alloy faster than you’d believe. We regularly find pinhole perforations within ten to fifteen years of installation, leaking flue gas into adjacent flues or wall cavities.
• Gap formation at the top connection on older flues. In pre-1890 rowhouses with unlined or deteriorating clay-tile flues, the masonry settles over decades. Gelco liners anchored at the top pull away, leaving a gap where creosote vapor and carbon monoxide bypass the liner entirely. Camera inspection catches this. A visual check from the roof does not.
• Wind-driven rain intrusion at Gelco multi-flue cap seams. Converted brownstones with four-flue stacks are the norm here, and multi-flue caps take a beating from harbor gusts. Seam leaks let water run down between flues, causing rust staining on brick and mortar erosion below the cap.
• Draft reversal in flues originally built for coal. Many Brooklyn Heights fireplaces were designed for coal, not wood. When a Gelco liner gets sized without accounting for the original shallow firebox or the shared stack configuration, you get smoke pushing back into the room instead of up the flue.
• Cross-contamination between tenant flues in converted buildings. One stack serving three or four apartments means one open abandoned flue can pull exhaust from an active flue below it into an upstairs unit. We’ve seen this exact scenario on Pierrepont Street, and it’s a carbon monoxide risk, not just a nuisance.

Gelco Service in Brooklyn Heights: What Local Conditions Mean for Your Equipment

Here’s the piece nobody tells you until you live it: Brooklyn Heights was designated New York City’s first historic district in 1965, and that single fact changes every exterior chimney job. If your Gelco cap, crown, or any visible chimney work faces the street, the Landmarks Preservation Commission has to sign off before the first tool comes off the truck. That’s not true in downtown Brooklyn. It’s not true in Cobble Hill. It’s true here, and it’s been true for sixty years.

What that means for Gelco owners is practical. If your multi-flue cap is rusted through and leaking, we can’t just swap it same-day. We document the condition, prepare the LPC-compliant replacement spec, and coordinate the approval before installation. Our familiarity with that process, and with what LPC will and won’t accept on historic rowhouses, is part of why people in Brooklyn Heights call us instead of a shop that’s never filed a landmark application. We’ve also learned which aftermarket 316Ti replacements hold up better than the original 304 in harbor-exposed locations, and we’ll recommend them when they’re the honest upgrade - part of our Brooklyn Heights Chimney Repair expertise.

Gelco Models & Products We Service in Brooklyn Heights

We work on the Gelco products most common in this neighborhood: 6-inch round stainless steel liners, 316Ti alloy flexible liners, 304 stainless rigid liners, and multi-flue chimney caps. That’s the full range we see in Brooklyn Heights rowhouses and converted brownstones.

On parts, we take the shop approach, not the salesman approach. When a Gelco liner or cap needs full replacement, we use genuine OEM Gelco parts. When the issue is isolated corrosion or a seam leak, we’ll often recommend a quality aftermarket stainless component, especially 316Ti for harbor-facing exposures, because it matches or exceeds the original alloy spec and lasts longer in this salt air. We’ll measure wall thickness, show you the remaining service life, and let you make the call with real numbers in front of you. Free second opinions on any written estimate, too. Always.

FAQs - Gelco Chimney Cleaning in Brooklyn Heights

Do I need Landmarks Preservation Commission approval to replace a Gelco chimney cap on my Brooklyn Heights brownstone?
Yes, if the cap or any part of the chimney is visible from the street. Brooklyn Heights is New York City’s first historic district, and exterior chimney work requires LPC review and approval before installation. We handle the documentation and coordination as part of the job.

How does the harbor wind affect Gelco stainless steel liners in Brooklyn Heights specifically?
The salt-laden wind off the East River and Upper New York Harbor accelerates pitting and corrosion on 304 stainless, causing pinhole perforations that let flue gas escape into adjacent flues. We see this pattern regularly in Brooklyn Heights and far less in inland Brooklyn neighborhoods a mile away.

Can you clean only one flue in a shared four-flue stack without disturbing the other tenants’ units?
Yes. Each flue gets swept and camera-inspected independently, and we seal off the others during the job. In fact, identifying and documenting each flue’s status before cleaning is standard practice for us on every Brooklyn Heights converted brownstone, because open abandoned flues are common and dangerous.

Why does my Gelco liner show rust streaks at the top near the cap?
Rust streaking at the top connection usually means water is getting in at the cap seam or the top plate, then running down between the liner and the old masonry. On harbor-facing Brooklyn Heights rooflines, it’s often salt-accelerated, and it’s worth a camera inspection before the corrosion spreads.

What should I do if I smell smoke in my upstairs apartment when the downstairs fireplace is in use?
Call us. That’s likely cross-contamination between flues in a shared stack, possibly from an open abandoned flue or a perforated liner. It’s a carbon monoxide concern, and you shouldn’t wait. Call (516) 289-9316 and we’ll schedule an inspection, and we’ll tell you straight what needs doing and what doesn’t. If it doesn’t need doing, Wendell will tell you that too.
