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.

AfterFast, Reliable Chimney Cap & Crown Across Clifton
Chimney cap and crown work in Clifton usually runs between $300 and $1,600 depending on whether we’re repairing a crown, recoating it, or fabricating a custom multi-flue cap for a two-family stack. Most jobs are done in a single visit. If you’re in Allwood, Athenia, Richfield, or anywhere else in Clifton and you’ve got water staining near the chimney or a draft smell you can’t place, call (551) 368-8859 and we’ll come take a look, camera in hand.
We know Clifton’s chimneys. They’re old, they’re mostly shared, and they were built for coal and oil before half of them got converted to gas. That changes what a cap or crown has to do. We don’t treat a 1958 two-family flue stack the same way we’d treat a 2005 single-family chase. The chimney tells us what it needs, and we’ll show you the footage so you can see it too.
Why Top Hat Chimney Is Clifton’s Preferred Chimney Cap & Crown Company
Wendell Pike started Top Hat Chimney in 1999, and he still puts his name on every job. That matters in Clifton, where a lot of houses share walls and a bad repair on one side can become the neighbor’s problem. We work the same streets year after year, and people see us around. Ask anyone on your street if they’ve had chimney work done in the last twenty years. There’s a good chance Wendell or one of his crew has been up on that roof.
Clifton homeowners call us because we answer the phone. A live person picks up, any hour, and it may well be Wendell himself. You get a straight price before a single tool comes off the truck, and that price is the one on the invoice. No bait-and-switch. No call center. Every job comes with our 90-Day Done Right Promise in writing, so if something isn’t right, one call brings us back.
We’re also familiar with how tight Clifton streets and driveways can get. Our trucks carry what we need, and our techs plan roof access before they arrive. That means fewer surprises for you and less time blocking the driveway while the job gets done.
Our Chimney Cap & Crown Services in Clifton
Our Chimney Cap & Crown team handles everything from a single missing cap on a Richfield Cape Cod to a full custom multi-flue cap for a two-family in Athenia. Here’s what we do most often in Clifton:
Cap Installation
A properly sized cap keeps rain, birds, and leaves out of a flue that’s already bigger than it should be. In Clifton, where the majority of homes were built between 1940 and 1965, the flues were sized for oil or coal. When the boiler got swapped for gas, the flue stayed. A correctly installed cap with the right mesh and top plate reduces downdraft and keeps nesting debris from making an oversized flue even worse.
Cap Replacement
Rusted, blown-off, or undersized caps are common on Clifton’s older roofs. We see caps that have been up there since the Nixon administration. Replacement is usually straightforward: we measure, match the flue dimensions, and install something built for the actual appliance now venting through it, not the oil burner that used to be in the basement.
Crown Repair
Clifton’s freeze-thaw cycles are hard on concrete crowns. When a 1950s clay tile crown cracks, water gets into the flue, the smoke chamber, and eventually the firebox. We repair crowns with proper sloping and drip edges so water sheds away from the flue instead of pooling and freezing. On shared two-family stacks, a cracked crown is an open door for water into both units’ flues.
Crown Coating
When the crown is still structurally sound but porous and weathered, we coat it with Gelco or a comparable sealant. It buys years at a fraction of the cost of a rebuild. We’ll tell you plainly if a coating will do the job or if the crown is too far gone. We don’t coat a crown that’s already spalled to the point of flaking. That would be taking your money for a problem we know will be back in spring.
We also build custom caps and multi-flue caps for Clifton’s shared stacks, which is where our local experience really shows. More on that below.

Trusted Brands We Service in Clifton
We install and service products from Gelco, Olympia Chimney, Famco, and Copperfield. These are the brands that hold up through northern New Jersey winters and the damp air that rolls in off the Passaic River lowlands. We stock common components so a cap replacement in Clifton doesn’t mean waiting a week on a parts order. When a custom multi-flue cap is needed, we build it to spec and install it with each flue isolated so each unit drafts properly.
Common Chimney Cap & Crown Problems We See in Clifton Homes
Clifton’s housing stock has a very specific set of chimney problems, and most of them trace back to the age of the buildings and the way they were converted from oil to gas. Here’s what we regularly find:
- Freeze-thaw spalling of the original clay tile crown. Winter in Clifton means repeated freeze-thaw cycles. Water seeps into hairline cracks, freezes, expands, and pops the crown apart from the inside. By spring the flue is open to weather and the damage is compounding.
- A gas furnace venting into an oversized, deteriorating shared flue. The old flues were sized for oil boilers that put out far more heat and draw. A modern high-efficiency gas furnace produces cooler exhaust that condenses inside the oversized flue. The result is acidic condensate that eats the clay tile liner, and backdraft that can push exhaust into living space.
- Missing or rusted caps allowing rain and birds into the flue. Clifton’s older homes often have chimneys with no cap at all, or one that rusted through years ago. Rain accelerates creosote breakdown, birds build nests that block draft, and leaf litter creates a fire hazard. All of it sits in a flue that’s already too large for the appliance it serves.
- Ground moisture from the Passaic River lowlands wicking into the chimney base. The damp conditions near the river work their way up through foundation masonry into the smoke chamber, worsening erosion that a crown coating alone won’t fix. We see this pattern constantly in the lower-lying streets of Clifton.
The Shared-Flue Problem: Why Clifton Is Different
Here’s the thing about Clifton that most chimney companies from outside the area don’t fully appreciate. In this city’s dense two-family homes, a single masonry stack commonly serves two separate flues, one for each unit’s heating system. That means a cracked shared wythe, or the masonry wall between the two flues, is not just your problem. It’s your neighbor’s problem too.
When a gas appliance in the downstairs unit vents into a flue with a cracked shared wythe, the exhaust doesn’t always go up and out. It can cross into the neighbor’s flue and backdraft into the upstairs unit. Carbon monoxide doesn’t care whose flue it is. We’ve seen this exact scenario more times in Clifton than anywhere else we work. A routine sweeping won’t catch it because a sweep looks at the flue, not the wythe between them. You need a camera inspection to see what’s happening inside the shared stack.
On a two-family home in Athenia, our tech found the neighbor’s gas furnace venting into the shared stack through a cracked clay tile wythe. The backdraft was sending exhaust into the upstairs unit’s second-floor bedrooms. We installed a multi-flue cap with custom dividers and sealed the crown with Gelco, isolating each flue so both furnaces drafted independently. That’s the kind of repair that doesn’t show up on a checklist. You have to be on the roof, looking at the actual stack, to know it’s needed.
The Oversized Flue Problem: Built for Oil, Converted to Gas
Most of Clifton’s housing stock dates from the 1940s through the mid-1960s. Those chimneys were built for oil or coal boilers, appliances that produced hot, high-volume exhaust. The flues were sized accordingly, often 8×12 or 8×8 clay tile. Then the conversions happened. Gas boilers and furnaces came in, far more efficient, with cooler exhaust and less draft. The flues stayed the same size.
That oversized flue creates condensation. The cooler gas exhaust hits the old clay tile, condenses, and produces mildly acidic water that eats the mortar joints and the tile itself. Over sixty or seventy years, the liner deteriorates to the point where it can’t hold the flue gases. Add a cracked crown or a missing cap, and water from storms accelerates the whole process. A chimney cap can’t fix the oversized flue, but it can stop water and debris from making the problem worse while we address the liner and crown issues.
Pricing for Chimney Cap & Crown in Clifton, NJ
Here are real numbers for the Clifton market. A standard single-flue cap installation runs $300 to $600 including the cap. A multi-flue custom cap for a shared two-family stack typically runs $800 to $1,600 depending on the number of flues, the crown dimensions, and whether we’re also repairing the crown surface underneath. Crown repair, including cleaning out the spalled material and rebuilding a proper slope with a drip edge, runs $500 to $1,000. Crown coating with Gelco usually falls between $350 and $650. If you’re a senior or a veteran, take 10% off any of those. Any repair over $200 gets $40 off.

FAQs - Chimney Cap & Crown in Clifton
You’ll usually see water staining on the ceiling or walls near the chimney chase on the top floor, or you’ll notice efflorescence, that white chalky residue, on the brick face below the crown. If you have a shared stack, water entering the crown can travel down either flue, so the damage may show up in your unit, the neighbor’s unit, or both. We confirm it with a camera inspection that shows the inside of the stack and the condition of the shared wythe. Call (551) 368-8859 and we’ll schedule the camera work.
That smell is likely backdraft from a shared flue. In Clifton’s two-family homes, both units often vent through the same masonry stack. A new high-efficiency furnace produces cooler exhaust with less draft than the old oil boiler it replaced. In an oversized 1950s flue, that exhaust can stall, condense, and push back into the other unit through a cracked shared wythe or a failed crown. This is a carbon monoxide concern and it needs to be addressed promptly. A multi-flue cap with dividers and proper liner work isolates the two flues and restores draft. Call us if you smell anything like exhaust indoors.
Yes. An unused, uncapped flue is an open pipe to the roof. Rain gets in, birds get in, and that moisture accelerates deterioration of the clay tile liner, which is probably already in rough shape after sixty-plus years. A properly sized cap with mesh keeps water and animals out while still letting the flue breathe. Call (551) 368-8859 for an estimate and we’ll tell you what size and style fits your flue.
A multi-flue cap with a center divider is usually the right choice. The divider separates the two flues so exhaust from one unit can’t cross into the other, which is exactly the problem that causes backdraft and carbon monoxide infiltration in Clifton’s two-family homes. We fabricate custom multi-flue caps to the actual crown dimensions, not an off-the-shelf size, because the old masonry crowns are rarely square or standard. The custom fit is what makes the isolation work.
Sometimes, if the crown is still structurally intact. A coating like Gelco seals hairline cracks and buys years. But if the crown has spalled, meaning chunks of the concrete have broken away, or if the edges have crumbled past the drip line, a coating won’t hold. It’ll peel and the water will be back by next winter. We’ll show you the close-up camera footage and tell you straight which option makes sense. For an exact quote in Athenia, call (551) 368-8859.
