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 Northampton
If you own a home in Northampton Borough, there’s a good chance your chimney was built before your grandparents were born. That’s not a guess. A large share of Northampton’s housing went up during the Atlas Cement era, between the 1890s and the 1920s. Those chimneys were built for coal. If yours was never relined for gas or oil, the flue is working far harder than it was ever designed to, and it’s probably showing it. We’re Top Hat Chimney, and we’ve been inside more of Northampton’s old chimneys than we can count. Wendell Pike started this company in 1999, and our Chimney Liner & Rebuild team handles everything from stainless steel liners to full rebuilds on row homes off Main Street and detached houses up toward Seemsville. Call (484) 859-1367 and we’ll talk it through before a single tool comes off the truck.
Why Top Hat Chimney Is Northampton’s Preferred Chimney Liner & Rebuild Company
Northampton homeowners have a right to be skeptical. The national outfits that run radio ads quote one number on the phone and send a stranger who finds $8,000 in “urgent” problems at the door. Wendell works differently. He publishes his name and license number. He has answered calls from the same communities since 1999, and he still runs into customers at the grocery store on Saturday. Ask anyone on your street about the work.
When we schedule a job in Northampton, you get a real arrival window, and if it slips, we call. No sitting around from noon to four wondering where the truck is. The crew shows up in uniform, background-checked, and they treat your row home the way they’d treat their own. Dispatch and scheduling are coordinated from the brand’s Philadelphia office, but the sweeps who arrive in Northampton know the borough’s chimneys specifically. That matters. A chimney on a cement-era row home tells you something a suburban chimney from 1995 doesn’t.
We never recommend work without camera footage. If a liner candidate needs replacing, you’ll see the crack for yourself on the scope. If it doesn’t, we’ll tell you it doesn’t, and we’ll explain what can wait. That’s why Northampton homeowners keep calling back. The camera footage and a plain-English verdict, every time, no exceptions.
Our Chimney Liner & Rebuild Services in Northampton
Stainless Steel Liner
For most Northampton row homes and older detached houses, a stainless steel liner is the right call when the original clay tiles have cracked. We use DuraFlex and Olympia products because they hold up under the Lehigh Valley’s freeze-thaw, which is harder on a chimney than most people realize. Cold air funnels through the Lehigh Gap and slams into the borough’s masonry every winter. A proper stainless liner keeps flue gases contained even when the old clay behind it has finally given up.

Flexible Liner
Northampton’s older chimneys are rarely perfectly straight. Coal-era construction didn’t always produce a clean vertical run. That’s exactly what flexible liners are for. We install them where a rigid liner won’t navigate the offsets and odd angles of a century-old flue. The liner is sized to the appliance it serves, not just jammed in. That sizing matters more in Northampton than in newer towns, because so many homes here were converted from coal to oil or gas, and the original flue dimensions often don’t match the modern appliance.

Liner Replacement
If you have an existing liner that’s failed, or a clay tile flue that’s cracked and spalling, replacement is usually faster and less invasive than a full rebuild. We scope the flue first. You see the footage. Then we talk options. In Northampton, we frequently pull old liners that were installed during a conversion decades ago and never inspected since. Replacing them is straightforward, and it’s almost always cheaper than dealing with the damage they cause if left alone.

Partial Rebuild
Sometimes the liner is fine but the masonry above the roofline isn’t. We rebuild the top courses of brick, repoint mortar joints, and pour a new concrete crown. On a Northampton row home, the crown takes a beating from water and freeze-thaw, and a cracked crown is an open invitation for water to work down into the flue. If the lower structure is sound, a partial rebuild gets you right without tearing out more than necessary. We’ll show you on the camera what’s actually wrong before any brick comes down.

Trusted Brands We Service in Northampton
We work with the liners and components we trust, because we’re the ones standing behind the job for 90 days after it’s done. That means DuraFlex stainless steel systems, HeatShield resurfacing for clay flues that can be saved rather than torn out, and Gelco and Olympia Chimney parts where they fit the job.

If your old system uses something we don’t stock, we’ll get it ordered and give you a straight answer on timing before we start.
Common Chimney Liner & Rebuild Problems We See in Northampton Homes
- Cracked clay tile liners from the coal era. Northampton’s original clay tiles are now well past 100 years old. Decades of heating and cooling, plus wet winters, have left many of them cracked, allowing carbon monoxide and flue gases to leak into wall cavities, especially in connected row homes where a neighbor’s flue runs right alongside yours.
- Coal-tar glazing baked onto flue tiles. When Northampton homes converted from coal to oil or gas, the residue from decades of coal fires didn’t go anywhere. It baked onto the tile surface as a hard glaze. Standard brushing won’t remove it, and if it’s left in place, it can reignite and fuel a chimney fire. We remove it before we install any liner or recommend a rebuild.
- Improperly sized flues from the conversion era. A flue built for coal doesn’t always vent a modern gas furnace well. The diameter is often wrong, which causes poor draft, backdrafting, soot staining around the appliance, and elevated carbon monoxide risk. We check the math on every liner job in Northampton. If the flue doesn’t match the appliance, we’ll show you on the scope and explain the fix.
- Spalled mortar and deteriorated crowns from Lehigh Gap weather. The freeze-thaw cycles that come through the Blue Mountain gap work on Northampton’s brick chimneys year after year. Mortar joints soften, bricks loosen, crowns crack. A chimney that looks fine from the ground can be failing at the top, and the liner is only as safe as the structure around it.
Pricing for Chimney Liner & Rebuild in Northampton, PA
A stainless steel liner replacement in Northampton typically runs $2,200 to $3,800, depending on flue length, access, and whether we’re pulling an old liner out first. Flexible liner work lands in a similar range, usually $2,000 to $3,500. A partial rebuild, where we replace the top courses of brick and pour a new crown, generally falls between $1,800 and $3,200. A full chimney rebuild in Northampton, where the entire structure above the roofline comes down and gets rebuilt, runs $6,000 to $12,000. HeatShield resurfacing, which can save a clay flue without a liner, typically costs $1,500 to $2,800.
Those are real numbers for Northampton’s housing stock, where older row homes and century-old flues mean the work is often more involved than a comparable job in a newer suburb. We give upfront pricing before the work begins, and the number you hear on the phone is the number on the invoice. Call (484) 859-1367 for a free estimate. No camera, no recommendation, no pressure.

FAQs - Chimney Liner & Rebuild in Northampton
If the clay tiles are intact and the flue is properly sized for your gas appliance, you may not need a liner at all, and we’ll tell you that straight. But in Northampton, we frequently find original clay tiles that are cracked from a century of use plus Lehigh Valley freeze-thaw. A cracked clay flue is a real safety issue, not a sales talking point. The only way to know is to scope it, and you watch the footage with us. If the tiles are sound but the flue is oversized for your furnace, a stainless liner may still be needed to restore proper draft. That’s a matter of the flue matching the appliance, not padding the bill. Call (484) 859-1367 and we’ll put a camera in it before we ever quote a liner.
Cold air pushes through the Lehigh Gap in the Blue Mountain ridge and hits Northampton harder than surrounding areas. Wet winters followed by rapid freeze-thaw cycles stress the brick and mortar relentlessly. Water gets into hairline cracks, freezes, expands, and widens them. Over decades, that’s how clay tile liners crack and how crowns fail. Northampton’s older chimneys, built for coal and never relined, take the worst of it. Annual inspection before heating season is the most reliable way to catch that damage early, and in this borough we recommend it every year, burn or no burn.
Yes, in most cases. A stainless or flexible liner goes in through the existing flue opening, and we don’t need to tear down brick to do it. We scope first, clean out the old glazing, then measure and install the liner sized for the appliance it serves. The masonry only needs rebuilding if it’s actually failing. Sometimes the top three courses are shot and we do a partial rebuild, but the liner itself goes in without touching the rest of the stack. We’ll show you what’s needed and what isn’t before any work begins.
HeatShield is a resurfacing product that seals and restores damaged clay flue tiles without installing a new liner. It can be a strong option for a coal-era flue in Northampton if the damage is limited to small cracks and spalling, and the flue is properly sized for the current appliance. It’s not right for every chimney. If the tiles are badly offset or the structure is compromised, a stainless liner is the safer call. We’ll scope the flue, show you what we find, and give you an honest recommendation. No pressure either way.
Coal-tar glazing is the baked-on residue left behind when a Northampton home burned coal for heat decades ago and later converted to oil or gas. It’s not a stain. It’s a combustible layer that can reignite under the right conditions and fuel a chimney fire. Standard brushing won’t remove it. We use mechanical methods and specialized equipment to strip that glazing before any liner goes in or before we assess whether the flue is even salvageable. Skipping that step means whatever you do next is built on top of a fire hazard.
