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.

Wendell Pike founded Top Hat Chimney in 1999, and in the decades since, we’ve scoped more Hillside chimneys than we can count. The township’s housing stock is different from what you find a few miles west. These are 1920s and 1930s homes built for coal, converted to oil, and now venting gas appliances into stacks that were never sized or lined for the job. That’s our specialty. We’re the local team that tells you straight what the camera shows and what can wait. No script, no pressure, no quote that changes at the door.
Why Top Hat Chimney Is Hillside’s Preferred Chimney Liner & Rebuild Company
Ask anyone on your street. We’re the crew that’s been working Hillside’s two-family blocks long enough to know which chimneys share a stack, which ones still have original clay tile, and which ones have been through three fuel conversions. Wendell puts his name and license number on every job, and the 90-Day Done Right Promise comes in writing. If the work isn’t right, one call brings him back. No arguing, no call center, no waiting on hold.
We answer the phone around the clock with a live person. It may well be Wendell himself picking up at 2 a.m. when you smell something odd near the chimney. Our background-checked, uniformed crew gives you a real arrival window in Hillside, and if we’re running late, we call. That matters here because parking on narrow streets off Maple Avenue or Liberty Avenue isn’t always simple, and we plan our day around getting to you when we say we will.
Hillside homeowners have told us the same story for years: a national chain sent a stranger, changed the number at the door, and vanished when the job wasn’t right. We built our name on being the opposite. Local, owner-operated, and reachable. We handle the full Chimney Liner & Rebuild process for this township, and we’ve earned a strong local reputation doing it.
Our Chimney Liner & Rebuild Services in Hillside
We serve Hillside with four core liner and rebuild services. Most homes in the township need at least one of these, and many need two. Here’s what each one actually involves.
Stainless Steel Liner
For Hillside homes where the original clay tile liner is cracked, missing, or never existed, a stainless steel liner is the standard fix. We install rigid stainless liners from Gelco and Copperfield, sized specifically to the BTU output of your furnace, boiler, or water heater. On Maple Avenue, we scoped a 1920s two-family where the gas water heater and boiler were venting into an unlined flue originally built for coal. Our camera showed third-degree creosote glaze and a cracked clay tile liner, so we installed a DuraFlex stainless steel liner sized for the modern appliances. After the rebuild, we verified draft with a smoke test and documented the shared-stack condition for both units.

Flexible Liner
When the existing flue has bends or offsets, a flexible stainless liner from DuraFlex often makes more sense than rigid sections. The terra cotta flues in Hillside’s older chimneys were built by hand, and they’re rarely perfectly straight. Flexible liners follow the existing path while providing a continuous, insulated barrier between combustion gases and the masonry. In attached two-family homes, this matters because the liner in one unit’s flue sits inches from the neighbor’s flue.

Liner Replacement
If your Hillside chimney already has a liner but it’s rusted through, separated at a joint, or the wrong size for the current appliance, we replace it. This is a common job in the homes between Conant Street and Hillside Avenue that were converted from oil to gas in the 1980s and 1990s. Many of those conversions left the old liner in place because it wasn’t required at the time. Gas appliances vent cooler exhaust, which creates more condensation inside a chimney, and that condensation eats at steel liners and mortar joints alike.

Partial Rebuild
Hillside’s freeze-thaw cycles are brutal on the exposed brick and mortar of tall, narrow chimneys. When the stack above the roof line has spalled bricks and eroded joints, we rebuild from the roofline up, installing a new concrete crown and a proper rain cap. We don’t recommend this unless the camera footage and close-up photos show structural deterioration. If the liner below is intact, a partial rebuild is often all you need. If the liner is compromised too, we do both in one visit.

Trusted Brands We Service in Hillside
We work with industry-trusted brands like DuraFlex, Gelco, Olympia Chimney, Famco, and Copperfield. That’s a short list, and it’s deliberate. We stock common liner components and connector parts locally so we’re not waiting on a truck from out of state when your boiler is down and the house is cold. For Hillside customers, that means faster turnaround and parts we know fit the older flue dimensions common in this township.
Common Chimney Liner & Rebuild Problems We See in Hillside Homes
Here are the issues that come up again and again in Hillside’s housing stock.
- Clay tile liners cracked from three generations of fuel conversions. Coal burned hot and dry. Oil burned hotter. Gas burns cooler and wetter. Each switch changed the chemistry inside the flue, and Hillside’s original clay tiles weren’t designed to handle the condensation modern gas appliances produce.
- Shared stacks in two-family homes trading draft problems between units. A single chimney stack serving both units via adjacent flues is the norm in Hillside’s attached homes. When one unit’s flue is blocked or deteriorating, it can depress draft in the neighboring flue, pushing carbon monoxide into the other household. We document this on camera and explain it in plain English to both owners.
- Freeze-thaw spalling on exposed brick and mortar. Union County’s winters swing across the freezing point repeatedly from November through March. Water gets into tiny cracks, freezes, expands, and pries bricks apart. Hillside’s narrow, tall chimneys take this punishment year after year, and the damage often starts above the roof line where you can’t see it without a ladder.
- Unlined or partially lined flues venting modern appliances. Some Hillside chimneys never had a clay liner at all. They were built for coal when direct brick venting was accepted. Today’s gas appliances need a correctly sized, insulated liner to vent safely and prevent condensation inside the masonry.

FAQs - Chimney Liner & Rebuild in Hillside
A liner rebuild in one unit’s flue can affect the other because the two flues sit side by side in the same masonry stack, separated only by a wythe of brick. We inspect both flues with the camera, and when we rebuild or reline one, we verify draft on both. In a shared-stack situation, a properly sized liner on your side can actually improve draft stability for your home, but we always check the neighbor’s flue before and after so the fix doesn’t create a new problem next door. Call (848) 331-2638 for an exact quote, and we’ll explain what the camera shows.
Yes, in almost every case. A chimney built in the 1930s for coal was not designed to handle the cooler, wetter exhaust from a modern gas boiler. Without a liner, that moisture condenses inside the brick and mortar, soaking through over time and causing deterioration inside the wall cavity. A stainless steel liner sized for your boiler’s BTU rating fixes this, and it’s required by code for most gas appliance installations. Let us scope it and show you exactly what the inside of your flue looks like.
It depends on where the damage is. If the deterioration is confined to the above-roof portion, a partial rebuild is usually the right call. If the flue liner inside is also cracked or missing, we address both at the same time. We won’t recommend a full rebuild unless the structure below the roof is compromised. The camera footage tells the story. Our crew will show you the pictures and let you decide with real information. Estimates are free, and we don’t upsell.
We run a camera up the flue from inside the house, or from the roof if access is easier. The camera shows us the exact condition of every foot of the liner, including cracks, missing sections, gaps at the joints, and creosote buildup. That footage goes to you, not to a sales script. We also check from the outside for staining on the interior walls, cracked firebrick, and mortar erosion where the flue exits the structure. You’ll see everything we see.
An undersized flue can’t move enough air to maintain proper draft, which means combustion gases, including carbon monoxide, can back up into the living space. It also causes the appliance to run less efficiently. In Hillside’s older homes, many oil-to-gas conversions kept the original flue, which was sized for a different fuel and a different venting load. The right fix is a properly sized stainless liner, and we can verify the current flue dimensions with a camera and a draft reading. Call (848) 331-2638 and we’ll take a look, no charge for the estimate.
