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 Cap & Crown Across Hightstown
Chimney cap and crown work in Hightstown, NJ typically runs $350-$900 for a standard cap installation, $400-$1,100 for crown repair, and $250-$650 for crown coating. Most jobs take half a day. But Hightstown is different from East Windsor or Plainsboro, because the borough’s historic housing stock dates to the 1870s through 1910s. Those chimneys were built for coal, not gas, and the cap-and-crown problems we see here are almost always tangled up in flue conversions that were never finished properly. Wendell Pike and his crew know these stacks, and we’ll show you camera footage before we recommend a single dollar of work. Call (609) 905-5820 for a free estimate.
Why Top Hat Chimney Is Hightstown’s Preferred Chimney Cap & Crown Company
We’ve worked on the Victorians and Italianates along Stockton Street, Rogers Avenue, and the streets radiating off Memorial Park long enough to know what to expect before we even put a ladder up. Wendell founded Top Hat Chimney in 1999, and he still runs the job himself. That means the person who answers your call is likely the person who shows up at your door, and the name on the work is a name you’ll see at the Hightstown diner on Saturday.
Our Chimney Cap & Crown team sees one pattern in Hightstown more than anywhere else: two-flue Victorian chimneys where the furnace flue was capped during an oil-to-gas conversion but never sealed, and the crown above both flues is now crumbling. That combination creates draft problems no standard cap job in newer construction ever touches. We address it because we understand it, and because we live with the freeze-thaw cycles the same way your mortar does.
Every job comes with our 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. No charge. No argument. We also answer the phone with a live person around the clock, and our pricing is delivered upfront before a single tool comes off the truck. You’ll know the number before we start, and the invoice will match it.
Our Chimney Cap & Crown Services in Hightstown
Cap Installation
A missing or undersized cap on a Hightstown Victorian is an open invitation for squirrels, raccoons, and starlings to build nests in a dormant flue, and that blockage can push carbon monoxide back into the house on the first cold snap. We install stainless steel caps sized to your flue, not whatever’s on the truck. On multi-flue stacks, that means measuring both flues and accounting for the abandoned one, which brings us to the next service.

Cap Replacement
If your cap is rusted through, blown off in a nor’easter, or simply the wrong size for a converted flue, we’ll replace it. In Hightstown’s older homes, we often find caps that were installed over flues still lined with original clay tiles, and those tiles are cracked or missing sections. A cap replacement without checking the liner underneath is like putting a new roof on a leaking house. We check first, with a camera, and we show you the footage.

Crown Repair
The crown is the concrete or mortar slab that caps the top of the chimney and sheds water away from the flue. In Hightstown, crowns take a beating from Central NJ’s freeze-thaw cycling. Water gets into hairline cracks, freezes, expands, and pries the crack wider. Repeat that for 30 or 40 winters and you have a crown that looks like a shattered sidewalk. We remove the failing material, rebuild the crown with a proper overhang and drip edge, and finish it so water actually runs off instead of through.

Crown Coating
For crowns that are still structurally sound but showing surface cracks, we apply a flexible crown coating, typically Gelco, that bridges minor cracking and resists further water intrusion. On Hightstown’s 1900s chimneys, this is the right call more often than a full rebuild, provided the underlying mortar isn’t spalled past saving. Cameras and a plain-English verdict, every time, no exceptions. We’ll tell you honestly if coating will buy you a decade or if the crown needs to be rebuilt.

Multi-Flue Cap
This is the Hightstown specialty. A multi-flue cap covers the entire top of the stack rather than individual flues, and on a two-flue Victorian with one active fireplace flue and one abandoned furnace flue, this is often the only cap that actually works. We custom-fit multi-flue caps from Olympia Chimney to clear both flues, keep animals out of the dormant side, and stop the draft reversal that happens when a capped-but-unsealed furnace flue interacts with an active fireplace flue. We’ll show you the draft readings before and after.

Trusted Brands We Service in Hightstown
We install and service caps and crowns from brands we’d put on our own homes: Olympia Chimney multi-flue caps, Gelco crown coatings, and Famco plates for sealing abandoned flues. If your Hightstown chimney has an existing liner by DuraFlex or HeatShield, we work with those systems too, and we keep common parts for Central NJ jobs on hand so we’re not waiting on a parts house in Trenton. Fast turnaround matters when your crown is letting water into the smoke chamber every time it rains.
Common Chimney Cap & Crown Problems We See in Hightstown Homes
- Crown erosion from freeze-thaw cycling. The soft, late-1800s brick mortar common in Hightstown’s historic district absorbs water, and Central NJ’s winter freeze-thaw oscillations work those hairline cracks open season after season. By the time you see spalling on the exterior, water has usually been tracking inside for years.
- Capped-but-unsealed furnace flues in converted coal chimneys. Many Hightstown homes were built with two flues: one for a basement coal furnace, one for upstairs fireplaces. When the furnace was converted to oil and later gas, the furnace flue was capped but never sealed at the base or relined. That abandoned flue creates negative draft that pulls smoke from the active fireplace flue into the living space and accelerates creosote buildup.
- Missing or undersized caps on multi-flue stacks. A standard single-flue cap doesn’t fit a Victorian chimney with two flues side by side. Animals nest in the dormant flue, block the active one, and carbon monoxide backs up into the house. We see this every fall in Hightstown.
- Clay tile liners cracked by water and age. Original clay tile liners in Hightstown’s pre-1910 chimneys are often cracked, missing sections, or absent entirely. A cap alone won’t fix a failed liner, and a crown repair won’t either. We camera the flue first and show you exactly what’s there.
Pricing for Chimney Cap & Crown in Hightstown, NJ
Let’s talk real numbers for Hightstown specifically. A standard stainless steel cap installation runs $350-$600 on a single flue. A multi-flue cap custom-fitted to a two-flue Victorian stack runs $600-$900. Crown repair, which means removing and rebuilding the failed crown, runs $400-$1,100 depending on the stack’s footprint and how much material has to come off. Crown coating with Gelco runs $250-$650. If the flue tile underneath is cracked or the abandoned furnace flue needs sealing at the base, that’s additional, and we’ll quote it after the camera goes in.

FAQs - Chimney Cap & Crown in Hightstown
Because capping a furnace flue is not the same as sealing it. In a two-flue Victorian chimney, the flue that once served a basement coal furnace was often capped at the top during the oil-to-gas conversion but never sealed at the base or relined. The abandoned flue still communicates with the active fireplace flue through gaps in the interior brickwork, so when your gas furnace fires, it pulls air backward through the fireplace flue instead of exhausting cleanly. A new cap on the fireplace flue does nothing to stop that negative-draft interaction. The fix is sealing the abandoned flue properly, typically with a Famco plate at the base, plus a multi-flue cap that manages airflow across the entire stack. We’ll verify the draft reversal with a smoke test and show you the before-and-after readings. Call (609) 905-5820 for a free estimate.
Yes, and in many cases that’s exactly what we do. If the bricks are spalling, meaning the faces are flaking off but the structural core is intact, the crown can usually be rebuilt without touching the brickwork below it. We remove the failed mortar or concrete crown, rebuild it with a proper overhang and drip edge, and coat it with Gelco to bridge hairline cracks. The camera goes in first to confirm the flue tiles aren’t cracked from years of water intrusion. If they are, you’ll see the footage before we recommend anything beyond the crown. Call (609) 905-5820 for a quote.
Every year, burn or no burn. Hightstown’s freeze-thaw cycling is particularly punishing to the soft late-1800s mortar used in the borough’s Victorian stock. A crown that looks fine in June can open up hairline cracks by March. Once a year is the same cadence we recommend for a sweep, and the crown inspection is part of it. Chimneys break in the off-season too. Call (609) 905-5820 to schedule an inspection.
A custom multi-flue cap, not a pair of individual caps. On a two-flue Victorian stack, a single multi-flue cap covers the entire top, clears both flues, keeps animals out of the abandoned side, and reduces the draft reversal that happens when a capped-but-unsealed furnace flue interacts with the active fireplace flue. We measure the full footprint, fabricate the cap from Olympia Chimney components, and seal the abandoned flue at the base. That combination is the only approach that actually works on Hightstown’s converted coal chimneys. Call (609) 905-5820 and we’ll walk you through it.
It genuinely works, but only when the crown is still structurally sound. A flexible coating like Gelco bridges hairline cracks and prevents water from entering through the top of the crown. On a Hightstown chimney from the 1900s with minor surface cracking, a coating can add a decade or more before a full rebuild is needed. But if the crown is spalled, crumbled, or missing chunks, coating it is a waste of your money. We’ll show you the camera footage, explain what we’re seeing in plain English, and recommend coating only when it will actually hold. You’ll never hear an upsell from Wendell.
