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 Repair Across Northampton
Chimney repair in Northampton typically runs $220-$1,200 for mortar repointing on the lowest-priced end and $3,500-$9,000 for a full chimney rebuild, but the most common job we do here, flue liner replacement on a century-old worker row home, sits between $1,800 and $4,200 depending on height and liner type. Northampton Borough’s housing stock has a specific problem that newer surrounding developments don’t: chimneys built for coal in the Atlas Cement era that were never relined when the furnace got converted to gas or oil. Wendell Pike and his crew have seen enough of these chimneys to know what’s behind the brick before we even get up there. Call (484) 859-1367 for a free estimate, and we’ll show you the camera footage of whatever we find before you spend a dollar on repairs.
Why Top Hat Chimney Is Northampton’s Preferred Chimney Repair Company
Top Hat Chimney has been cleaning, inspecting, and repairing chimneys since 1999, and a lot of those chimneys are right here in Northampton. Wendell started this business himself and still climbs ladders and runs the camera scope on jobs. When you call, you get a live person answering, twenty-four hours a day. It may well be Wendell picking up the phone. That matters when you’re a homeowner in the Borough who has already dealt with a national chain that sent a stranger, changed the price at the door, and then never called back. Ask anyone on your street. They’ll tell you the same thing: a written quote before work starts, the number you see is the number you pay, and a 90-Day Done Right Promise in writing on every single job.
We work on rows homes off Main Street, houses up near the old Atlas complex, and the scattered detached homes toward the Lehigh. That local familiarity means we know what to expect before we start. Housing along streets like Washington Avenue and Alliance Street and near the Northampton Memorial Community Center is often older brick construction with chimneys that predate modern building codes. Our experience in Northampton means we already know your chimney’s likely problems before we’ve unloaded the ladder. And when we finish the job, Wendell’s name and license number are on the paperwork, not a corporate logo from some out-of-state franchise.
Our Chimney Repair Services in Northampton
We are a locally owned, owner-operated company, not a national outfit with rotating crews. For Northampton homeowners, that means the person who quotes your repair is the same person who does the work and the person you’ll see at the hardware store on Saturday. Here are the repairs we do most often in Northampton:
Mortar Repointing & Tuckpointing
Freeze-thaw cycling is the big culprit for mortar joint failure in Northampton. Cold air funnels through the Lehigh Gap along the Blue Mountain ridge and pushes frost deep into century-old brick. When the joints start powdering, water works its way behind the brick, and then you get spalling, efflorescence, and eventually a leaning stack. We repoint with mortar matched to the original era of the house, not a generic gray that stands out like a patch. A typical repointing job on a Northampton row home runs $500-$1,800 depending on how many courses are failing.
Spalling Brick Repair
Spalled faces on chimney brick mean water has gotten in and frozen. In Northampton, brick row homes with single-wythe chimneys (one brick thick) are especially vulnerable because there’s no second layer to absorb the damage. We’ll cut out the soft or broken brick, replace it with a matched historic brick, and point the surrounding joints. If more than a third of the chimney face is spalling, we’ll have an honest conversation with you about whether a partial rebuild is the better long-term call. A typical spall repair here runs $350-$900 per affected area.
Chimney Waterproofing
The freeze-thaw cycle in the Lehigh Valley is harsher on brick than most homeowners realize, and it isn’t just winter that does the damage. Fall rain soaks into the masonry, then the first hard freeze expands it. We apply a breathable siloxane-based waterproofing treatment to the exterior brick so water stays out but the brick can still release moisture from the inside. That’s the difference between sealing the chimney and trapping water inside. Waterproofing an average Northampton chimney runs $350-$700 and takes a single afternoon.
Flashing Repair
Flashing is the metal that bridges your chimney to your roof, and when it fails, water runs straight down along the chimney chase into your attic or along your roofline. On the steep-pitched roofs common around the old borough, especially on the hipped-roof Dutch Colonials and the two-story worker houses, flashing takes a beating from wind-driven rain and heavy snow. We remove old tar and cracked step flashing, install new copper or galvanized flashing, and reflash the roof-to-chimney junction properly. This runs $450-$1,200 on a typical Northampton home.
Flue Liner Replacement
This is the job we end up doing more than any other in Northampton. The original clay tile liners in homes built between 1890 and 1920 were sized for coal combustion, not for a modern gas or oil furnace. When the conversion happened, in a lot of cases, no one updated the liner. That leaves an undersized flue that can’t draft properly, spilling carbon monoxide into the house and trapping coal-tar glaze that can reignite. We install DuraFlex stainless liners and HeatShield resurfacing systems sized correctly for your specific appliance. This is not a brush-and-go job. This is the repair that makes the chimney safe. Typical liner replacement on a Northampton row home runs $1,800-$4,200.
Chimney Rebuilding
When mortar joints have failed across the entire stack, when brick is spalled or leaning, or when the crown has crumbled and the flue is cracked behind the plaster, a rebuild is the honest answer. We rebuild from the roof line up (or sometimes entirely, if the damage extends into the house), using correct historic brick and age-matched mortar. We also rebuild the crown at a proper overhang to shed water the way the original never did. A full rebuild on a Northampton chimney typically runs $3,500-$9,000. That’s honest pricing, and before you write the check, you’ll have seen the camera evidence that made it necessary.

Trusted Brands We Service in Northampton
We stock parts for the brands that hold up in Northampton’s wet winters and freeze-thaw cycles. We work with Copperfield for caps and dampers, DuraFlex for stainless steel chimney liners, and HeatShield for resurfacing clay tile flues that are structurally sound but cracked or glazed. Because we keep common parts on hand for Northampton jobs, most repairs are completed in a single visit, not three callbacks. You won’t be waiting two weeks for a part to ship from a warehouse across the country. When your heating season is on the line, that matters.
Common Chimney Repair Problems We See in Northampton Homes
- Coal-era flue tiles left in place after oil or gas conversion. This is the signature Northampton problem. A chimney built for coal in 1915 was never meant to vent a modern furnace. The flue is often undersized, the coal-tar glaze is still baked onto the tile, and standard brushing alone won’t remove it.
- Freeze-thaw spalling on single-wythe brick. Cold from the Lehigh Gap accelerates the freeze-thaw cycle. Water gets behind the brick face, freezes, and pops the face off. That’s what spalling looks like on a Northampton row home.
- Crumbling crowns on century-old chimneys. Many of these worker-home crowns were poured thin and never had a proper drip edge. Once the crown starts crumbling, water funnels into the flue and causes rusted dampers and cracked fireboxes.
- Leaking flashing at the roof line. Northampton’s older homes often have steep roofs and original flashing that has been tarred and re-tarred to death. When the flashing fails, the leak isn’t always at the chimney. It’s along the roofline or inside the attic.
All of these are tied to the same root cause: Northampton Borough grew fast during the Atlas Cement era, and the housing stock is mostly a century old or more. We don’t see these problems in the same concentration in newer suburbs like Catasauqua or Schnecksville. We see them everywhere in Northampton.

FAQs - Chimney Repair in Northampton
In most cases, yes. If your home was built between 1890 and 1920 and the flue liner was never replaced after a coal-to-gas conversion, the clay tile liner is almost certainly undersized for a modern gas furnace, and it may have coal-tar glaze that can reignite if heated. We’ll send a camera scope up the flue and show you exactly what we’re seeing before we recommend a liner. A properly sized DuraFlex stainless liner or HeatShield resurfacing makes the chimney safe to use. Call (484) 859-1367 to schedule an inspection.
Sometimes glaze can be removed with a proper chemical treatment and rotary cleaning. More often, on a chimney this old, the flue tiles are also cracked or misaligned, and the right fix is a new liner or resurfacing. We’ll show you the camera footage and tell you which route makes sense for your chimney. We never recommend a liner or rebuild without proof you can see with your own eyes. Call (484) 859-1367 to talk it through.
Northampton sits in a cold-air funnel through the Lehigh Gap. Winter air rushing through the Blue Mountain ridge drops temperatures faster and deeper than in surrounding areas, which means the freeze-thaw cycle in your brick gets more aggressive. Century-old single-wythe brick chimneys have no second layer to absorb that frost expansion, so the face of the brick pops off. That’s spalling, and it happens faster here because the physical geography works against the masonry. Annual inspection catches it before you’re looking at a rebuild. Call (484) 859-1367 for a checkup.
Yes. Once a year, burn or no burn. Chimneys break in the off-season too. Freeze-thaw damage doesn’t care whether you had a fire last weekend. It just needs water and a hard freeze, and Northampton provides both. The third-degree creosote problem isn’t just from heavy use, it’s from a damp, cold flue and from coal-era glaze that was never addressed. An annual inspection is the cheapest insurance against a five-figure rebuild. Call (484) 859-1367 and we’ll get you on the schedule.
We start with the camera scope. If the mortar joints are failing but the flue tiles are intact and the brick is solid, repointing is the answer. If the flue is cracked, the crown is crumbling, and the brick itself is spalling across more than a third of the chimney, rebuilding is the honest route. In Northampton, that decision comes down to whether the original coal-era structure is salvageable. We’ll show you the footage before we quote anything. Call (484) 859-1367 for a free estimate.
