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 Hellertown
If your Hellertown home still vents a furnace or water heater through an original coal-era chimney, odds are good that flue needs a liner. Most of the borough’s housing stock was built before 1940, when chimneys were sized for high-output coal appliances. The gas and oil furnaces that replaced those coal burners decades ago vent into stacks that are too large, often unlined, and deteriorating from the inside out. We inspect before recommending anything, and nothing gets proposed without camera footage you can see for yourself. Call (484) 603-6713 for a straight answer and a free estimate.
Why Top Hat Chimney Is Hellertown’s Preferred Chimney Liner & Rebuild Company
Wendell Pike founded Top Hat Chimney in 1999, and he has worked the same communities since. The Hellertown borough grid is compact enough that our crews know the difference between a 1920s brick twin on Main Street and a 1950s frame home off East Depot Street without looking at a map. That matters when you’re quoting liner work, because the chimney those two houses came with are not built the same way.
Hellertown customers see the same crew on repeat calls, and Wendell’s name is on every invoice. The 90-Day Done Right Promise is stamped on every job in writing. If the liner install isn’t right, one call brings the crew back at no charge. Calls are answered by a live person day or night, often Wendell himself. Upfront pricing is given before any tool comes off the truck, and the number you hear on the phone is the number on the invoice.
We answer to the people who live here. Not to a regional office. Ask anyone on your street who has had liner work done, and you’ll hear the same thing.
Our Chimney Liner & Rebuild Services in Hellertown
Our Chimney Liner & Rebuild work in Hellertown falls into a few categories, and most homes need a combination rather than a single fix. Before anything gets recommended, we run a camera through the flue and show you the footage. You should never sign off on a liner or rebuild you haven’t seen with your own eyes.
Stainless Steel Liner
A stainless steel liner is the standard fix for Hellertown’s oversized coal-era flues. When a modern gas furnace vents into a chimney built for a coal fire, the flue is too big for the appliance. Draft stalls. Carbon monoxide can push back into the living space. We install properly sized stainless liners, usually from DuraFlex, that restore correct draft and separate the appliance exhaust from the old masonry.

Flexible Liner
For chimneys with offsets or tight bends, a flexible liner does what rigid sections cannot. Many Hellertown row homes and twins have flues that jog partway up the stack, and a rigid liner simply won’t make the turn. Flexible stainless runs from the appliance connection to the crown in one continuous piece, with fewer joints and fewer leak points.

Liner Replacement
When the existing clay tile liner is cracked, shifted, or spalled, replacement is usually the only fix. Homes along Saucon Street and in the blocks around the old borough core show the same pattern: terra cotta tiles laid in the 1920s and 30s, now cracked from decades of heat and freeze-thaw cycling. We remove what’s failing and install a new liner that matches the appliance, not the original coal rating.

Partial Rebuild
Not every chimney needs to come down. When the upper courses of brick are spalled and the mortar joints are failing but the lower stack is sound, a partial rebuild from the roofline up solves the problem without tearing out good masonry. We rebuild with bricks matched to the original as closely as possible, reflash the base, and install a proper crown. The liner gets inspected at the same time, because a rebuilt stack with a failing liner is half a job.

Trusted Brands We Service in Hellertown
We work with manufacturers whose hardware holds up in Saucon Creek valley weather: DuraFlex, Olympia Chimney, and Copperfield are the brands we install most often on Hellertown liner and rebuild jobs. Because the borough’s housing stock is so consistent, we keep common liner diameters and rebuild components stocked on the truck. That means less waiting on a second trip when we’re working on a row of pre-WWII twins.
Common Chimney Liner & Rebuild Problems We See in Hellertown Homes
- Coal-era flues oversized for modern gas appliances. A chimney built for a coal furnace in 1930 vents a gas furnace now. The flue is twice the size it should be, draft weakens, and combustion gases linger instead of exhausting.
- Unlined masonry chimneys on pre-1950s homes. Many Hellertown houses never received a liner when they converted from coal. Creosote glaze and hidden gaps behind walls make a camera-verified liner replacement necessary, not optional.
- Freeze-thaw spalling and mortar joint failure. Cold air pooling in the Saucon Creek valley means repeated freeze-thaw cycles from late fall through early spring. Water gets into brick, freezes, expands, and cracks joints. The top few feet of the stack suffer first.
- Clay tile liners cracked by appliance conversion. The original terra cotta tiles were fired for coal exhaust. Years of gas heating cycles have thermal-shocked them into hairline cracks that widen into gaps. Carbon monoxide finds those gaps.
Pricing for Chimney Liner & Rebuild in Hellertown, PA
A stainless steel liner installation in Hellertown typically runs $1,800 to $3,200, depending on flue height, liner diameter, and access. Flexible liner runs about the same, sometimes a few hundred more when the flue has complex bends. Liner replacement sits in the $2,000 to $3,800 range. A partial rebuild from the roofline up usually falls between $2,500 and $5,500, with full rebuilds starting around $6,000 and going up from there on the borough’s taller two-story stacks. The age of the home matters more than square footage here: a 1920s twin with an interior flue costs more to access than a 1960s exterior chimney.
We quote the price before work starts, and the quote doesn’t change when the crew arrives. Every estimate is free, and if you have a written estimate from another company, we’ll give you a second opinion at no charge. Seniors and veterans always get 10% off.

FAQs - Chimney Liner & Rebuild in Hellertown
Because the conversion was almost never done with the flue in mind. Most Hellertown homes converted from coal to gas or oil in the 1950s through the 1970s, and the only change made was the appliance itself. The chimney stayed the same. A coal burner in a 1930s home needed a flue with a cross-section of roughly 50 to 70 square inches. A modern gas furnace needs maybe 12 to 20. The oversized flue cools the exhaust before it exits, which stalls draft and leaves acidic condensation on the masonry. The fix is a properly sized liner, almost always stainless. Call (484) 603-6713 for an inspection and we’ll show you the measurements.
In most cases, no. Cracked clay tiles in a Hellertown chimney cannot be glued or patched back together in a way that holds up to heat cycling. When tiles crack, the gaps allow combustion gases to reach the surrounding masonry and any wood framing nearby. The correct fix is either a stainless liner installed through the existing flue or, if the masonry itself is compromised, a rebuild. We’ll show you the camera footage before recommending either path. If the rest of the stack is sound, a liner alone is usually enough and we’ll say so plainly.
Freeze-thaw cycling is the primary reason Hellertown chimney stacks fail from the roofline up. Water seeps into brick pores during the day, freezes overnight when valley air pools cold, and the expanding ice spalls the brick face and widens mortar joints. Over one winter, the damage is cosmetic. Over five or ten, the top courses lose structural bond and start leaning. When we rebuild in Hellertown, we use a breathable mortar harder than the original lime-based mix and install a poured concrete crown with a drip edge so water sheets off the stack instead of soaking in. That buys decades, not seasons.
Rarely do we recommend a full rebuild when a liner alone solves the problem. The liner’s job is to contain exhaust. The masonry’s job is to hold the liner and keep water out. If the brick and mortar are structurally sound, a stainless liner installed through the existing flue does the job for thousands less than a rebuild. If the masonry is spalled, leaning, or the flue has collapsed internally, a rebuild or partial rebuild becomes necessary. We make the decision with you, looking at the camera footage together. Nothing gets recommended because it’s more profitable.
A Level 1 inspection is visual. We look at the firebox, the damper, the accessible flue from the top and bottom, and the exterior stack. It’s appropriate when nothing about the system has changed. A Level 2 inspection adds a camera scan of the full flue interior plus access from the attic, crawl space, and roof. That’s the standard that matters for liner work in Hellertown. You cannot see cracked clay tiles, missing mortar between flue sections, or hidden gaps behind walls from either end of the chimney alone. Before we install any liner, we run the camera. The footage and a plain-English verdict, every time, no exceptions. Call (484) 603-6713 to schedule an inspection.
