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.
Fast, Reliable Chimney Liner & Rebuild Across Bay Ridge
Chimney liner replacement in Bay Ridge typically runs $3,200-$6,800, and a full chimney rebuild costs between $9,500 and $18,000 depending on roof access and how much masonry the salt air off the Narrows has eaten away. We’re Top Hat Chimney. Wendell Pike founded this company in 1999, and he still works the rooftops himself. If you own one of Bay Ridge’s 1920s brick row houses with the original terra cotta liner still in place, that liner is now 80 to 100 years old. Call (516) 289-9316 and Wendell or his crew will come look at it, camera in hand, before anyone quotes you a dime.
Bay Ridge is different from the rest of Brooklyn. Your chimney sits in salt wind off Upper New York Bay, on a street where your flue may share a party wall with your neighbor’s. That changes how we diagnose, how we price, and what we recommend. We know the blocks around Ridge Boulevard, Shore Road, and the 11209 zip code. And we’ll tell you straight if the work can wait.
Key Takeaways for Bay Ridge Homeowners
- An original clay liner in a 1920s Bay Ridge row house is nearly always oversized for today’s gas appliances, which causes condensation, poor draft, and acidic damage.
- Salt-laden wind off the Narrows degrades mortar crowns and flashing measurably faster than inland Brooklyn.
- Shared flues in attached row houses mean a neighbor’s gas exhaust can push into your home through a cracked or absent liner.
- We never recommend a rebuild without camera footage you can watch yourself, on-site.
- Wendell Pike puts his name on every job, backed in writing by the 90-Day Done Right Promise.
Why Top Hat Chimney Is Bay Ridge’s Preferred Chimney Liner & Rebuild Company
We’ve spent over 29 years working chimneys in Brooklyn neighborhoods like this one, and we know what the salt wind does to a brick chimney. When we climb onto a roof off Ridge Boulevard, we don’t just look at the flue. We look at the crown, the flashing, and the mortar joints between the bricks. In Bay Ridge, those three things are often the reason the liner failed in the first place. A liner installed into a crumbled crown leaks within a season. We fix the whole stack, not just the pipe inside it.
Our Bay Ridge customers call us back because the number on the invoice matches the number on the phone quote. That’s not a policy. That’s how Wendell runs the company. A live person answers the phone 24/7, and it may well be Wendell himself. We arrive in uniform, background-checked, with a real arrival window, and we call if the window slips. Our reviews from Bay Ridge homeowners are strong, and you can ask anyone on your street.
We bring the camera every time. You’ll see the footage of what’s inside your flue before we recommend anything. If you don’t need a liner, we’ll tell you. If you do, you’ll see exactly why. No exceptions.
Our Chimney Liner & Repairs Team Serves Bay Ridge
We cover all of Bay Ridge, from the avenues off Shore Road up toward the Gowanus-side boundary, including 11209 and the northern edge into 11220. Our Bay Ridge scheduling runs through our New York City office, and our crews serve the neighborhood locally. Here’s what we do most often.
Liner Replacement
Most Bay Ridge row houses still have their original terra cotta flue liners from the 1920s or 1930s. Those liners were sized for oil burners. After gas conversion, the flue is chronically oversized. That causes poor draft, condensation inside the chimney, and acidic byproduct that eats mortar joints from the inside. A liner replacement, typically a stainless steel system sized correctly for your gas appliance, fixes the draft problem and stops the acid. In Bay Ridge, a typical liner replacement runs $3,200-$4,900 for a single flue stack.
Flexible Liner
On attached row houses where the flue has off-sets or a shared stack makes rigid sections awkward, a flexible stainless liner is often the simplest fix. We install DuraFlex flexible liners because they hold up in Bay Ridge’s particular conditions: salt air, frequent nor’easters, and damp brick. A flexible liner is pulled through the existing flue, so roof access stays quick on tight streets where a full scaffold would block a neighbor’s stoop. A typical flexible liner install in Bay Ridge runs $2,800-$4,400.
Stainless Steel Liner
When the original clay liner is cracked or missing and the appliance is gas, a stainless steel liner is the right call. Not galvanized steel. Not a repair patch. A correctly sized stainless liner rated for your specific appliance, installed with proper insulation where code requires. On Bay Ridge blocks where shared flues create back-draft problems, the insulation matters. An insulated stainless liner keeps flue gas hot enough to draft properly and resists the acidic condensate that eats cheaper liners. Expect $3,400-$5,600 in Bay Ridge for a standard stainless install.
Partial Rebuild
Sometimes the liner is fine but the top two or three courses of brick are spalled from salt and freezing cycles. A partial rebuild means tearing down to stable brick, setting new brick to match, pouring a proper concrete crown with overhang, and setting a cap. In Bay Ridge, partial rebuilds run $2,500-$5,800 depending on how far down the damage goes. We will not wrap a chimney in chicken wire and coating. We rebuild it with brick, the way it was built in the 1930s.
Trusted Brands We Service in Bay Ridge
We install and service liners, caps, and crowns from Gelco, Olympia Chimney, and Famco. These are the brands we trust on Bay Ridge rooftops, because they make products that hold up in salt air and stand behind their warranty. We keep common parts stocked for these systems in our crib, so a Bay Ridge chimney liner job doesn’t stall waiting on a backorder. If a Famco cap gets ripped off in a nor’easter, we can usually get you a replacement the same week.
Common Chimney Liner & Rebuild Problems We See in Bay Ridge Homes
- Shared flue cross-contamination. On attached row house blocks, flues sometimes share a party wall or even a common stack. When a neighbor’s gas boiler vents into that stack and your liner is cracked or absent, exhaust can push into your home. This is a Bay Ridge specific problem, not a generic chimney problem, and it’s one of the first things we check on any terraced block.
- Oversized oil-era liners on gas appliances. The 1920s and 1930s clay tile liners were built for oil burners that ran hot. Modern gas boilers run cooler and produce water vapor. In an oversized flue, that vapor condenses, drips back onto the tile, and breaks it down from the inside out. You don’t see it until white staining shows up on the brick face.
- Salt-driven spalling at the crown. The Narrows channels wind across Bay Ridge rooftops all year. Salt spray settles on chimney crowns, freezes, and pops the mortar. A spalled crown lets water into the flue, which deteriorates any liner repair quickly. We usually rebuild the crown as part of any liner or partial rebuild job in Bay Ridge.
- Nor’easter flashing failures. Winter storms funneling through the Narrows put acute stress on chimney flashing. When flashing tears, water runs straight down the outside of the liner and into the attic. We see this most on homes along Shore Road and the blocks running down toward the belt.

FAQs - Chimney Liner & Rebuild in Bay Ridge
You’ll notice a gas smell inside your home, not from your own burner, that gets worse when your neighbor’s boiler kicks on. Or you’ll see moisture and staining on an interior wall adjacent to a party wall. In attached Bay Ridge row houses, shared or adjacent flues are common. We run a camera to map the flue and use a draft test to find where exhaust is entering. If fumes are coming from a shared stack, this is not a DIY situation. Call (516) 289-9316 and we’ll inspect it.
Almost never, and here’s why: the flue was sized for an oil burner that produced hot, dry exhaust. A gas boiler produces cooler, wetter exhaust. In an oversized flue, that moisture condenses, and the acidic condensate dissolves the mortar between the clay tiles and eventually the brick itself. If you’ve converted to gas and still have the original terra cotta liner, call us for a camera inspection. If the liner is intact, you may be fine. If it’s cracked or glazed with third-degree creosote, it needs to be replaced. Call (516) 289-9316 for a free evaluation.
That’s efflorescence, and in Bay Ridge it usually means one of two things: either salt spray off the Narrows is soaking into the brick and wicking through, or moisture from a converted gas appliance is condensing inside an oil-era flue and pushing out through the masonry. On blocks along Ridge Boulevard, we spot this staining from the street regularly. It’s a visible sign the liner and possibly the interior chimney wall need attention. The fix starts with a camera inspection to identify the moisture source. Call (516) 289-9316.
In Bay Ridge, the deciding factor is the masonry. If the brick is sound, the crown is intact, and the flashing is good, a liner replacement is enough. If the salt wind has spalled the top courses, the crown is cracked, and water has gotten behind the brick, a liner alone will fail fast. We’ll show you the camera footage of the flue and photos of the exterior to make the call together. Nothing is recommended without evidence you can see for yourself. Call (516) 289-9316 and we’ll walk it with you.
Sometimes, if the water is coming straight down the flue opening and the crown is still solid. But on Bay Ridge rooftops, a cap alone rarely fixes the problem. The usual culprit is a spalled crown, failed flashing, or both. A cap keeps rain out of the flue. It doesn’t stop salt-driven moisture from soaking into brick and destroying the mortar joints. We’ll tell you straight if a cap is enough, or if the crown needs a rebuild. A Famco or Gelco cap is usually part of a larger crown repair in this neighborhood. Call (516) 289-9316 for a free assessment.
One Bay Ridge Problem a Generic Chimney Page Never Tells You
Attached brick row houses built between the 1920s and 1940s in Bay Ridge often have flues that run close to or share a stack with the house next door. When a neighbor’s gas appliance vents through that shared stack and your flue has a cracked liner or drifted out of alignment, the exhaust follows the path of least resistance. That path can be your upstairs hallway. We ran into this on a block near Ridge Boulevard not long ago. On a row house block near Ridge Boulevard, we pulled a cracked original terra cotta liner from a 1920s semi-detached home, less than a month after a gas conversion. Our techs spotted white efflorescence bleeding down the brick face from the street, a signature of moisture condensing inside an oil-era flue now oversized for a gas boiler. We installed a DuraFlex stainless steel liner, rebuilt the chimney crown with proper overhang, and added a Famco cap to close off the flue from the salt-driven moisture that had been eating the mortar joints since the last noreaster.
That job was not an upsell. It was a liner that had failed, a crown that was letting salt water in, and a shared-stack draft problem that had to be corrected. This is what we mean when we say Bay Ridge demands a local eye. A chimney sweep from an inland Brooklyn neighborhood might never check the neighbor’s venting. We do, every time.
Call (516) 289-9316. We’ll schedule a time that works, show up on time, put a camera down your flue, and tell you the truth about what we find. If the work can hold off, we’ll say so. If it can’t, you’ll see the footage and know exactly why. Estimates are free. Second opinions are free, too. Bring us a written estimate from any other company and we’ll give you our read on it, no charge.
