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 Hellertown
If you live in Hellertown, chances are your chimney was built for coal, not for the gas or oil furnace venting into it today. Most homes in the borough’s pre-WWII core have original masonry stacks with terra cotta flue liners that are cracked, crumbling, or missing entirely. That’s not a cosmetic issue. It’s a draft, backdraft, and carbon monoxide issue. Top Hat Chimney repairs these chimneys every week, and we’ll show you exactly what’s wrong on camera before any work begins. Call Wendell and his crew at (484) 603-6713 for a straight answer and a free estimate.
Key Takeaways
- Hellertown’s older homes were built with coal chimneys, and most were never relined when furnaces switched to gas or oil.
- Mortar repointing and spalling brick repair are the two most common fixes we do in the borough.
- We never recommend a repair without camera footage you can watch alongside us.
- Free estimates, no trip charge inside the county, and a 90-Day Done Right Promise on every job.
Why Top Hat Chimney Is Hellertown’s Preferred Chimney Repair Company
Wendell Pike has been working chimneys since 1999, and his name goes on every job we do in Hellertown. That’s not a marketing line. It means when we repoint a chimney on Clauser Street or replace a liner near Dimmick Park, Wendell answers if you call with a question a month later. Homeowners in the borough have dealt with the national outfits that send a stranger, change the price at the door, and disappear after the check clears. We run into the same problem, and we built the company to be the opposite of that.
Our techs know the old borough grid because they work it constantly. They pull up to a two-story brick twin on Rentzheimer Drive and can guess the flue is oversize before they even climb the ladder. That local knowledge saves you time and keeps us honest about what actually needs doing. Every repair is backed by our 90-Day Done Right Promise, in writing, on every single job. If it’s not right, one call brings us back. No argument, no re-quote.
We also answer the phone around the clock. Not a call center. A live person. It may well be Wendell himself picking up at 11 p.m. when you smell something odd from the fireplace.
Our Chimney Repair Services in Hellertown
Mortar Repointing in Hellertown
The freeze-thaw cycling in the Saucon Creek valley is hard on old mortar. Hellertown’s brick chimneys go through dozens of cycles every winter and early spring, and each one widens hairline cracks until water gets in and makes everything worse. Repointing means cutting out the failed mortar joints and replacing them with a mix that actually matches your brick and handles Pennsylvania weather. On most Hellertown homes, this is what needs doing long before anyone should talk about rebuilding. A typical repointing job on a two-story borough chimney runs $800 to $1,800 depending on how much of the stack needs work.
Spalling Brick Repair in Hellertown
Spalling is what happens when water soaks into brick and freezes, popping the face off the brick itself. You’ll see flaking brick and reddish debris on the roof or at the base of the chimney. Homes along Main Street and the side streets around the old steel-era housing stock see this constantly because the original brick is decades past its prime. We remove the damaged brick, replace it with matched units, and address the water entry that caused it in the first place. Spalling repair in Hellertown typically costs $400 to $1,200 per section, and it’s far cheaper than waiting for the stack to start leaning.
Chimney Waterproofing in Hellertown
If you’ve already got water staining inside the house near the chimney, or you’ve had mortar work done twice in ten years, the problem is likely water absorption through the masonry itself. We apply a vapor-permeable waterproofing treatment from Gelco that keeps rain and snowmelt out while still letting trapped moisture escape. On Hellertown’s older brick, this is the difference between a chimney that lasts another 30 years and one that needs major work after three winters. Waterproofing a standard borough chimney runs $500 to $900, and it’s the single best dollar-for-dollar fix for freeze-thaw damage.
Flashing Repair in Hellertown
Flashing is the metal joint where the chimney meets the roof, and on Hellertown’s two-story frame and brick homes it’s often original to a 1970s or 1980s re-roof, which means it’s failing. Water follows the gap and rots the roof decking, the attic framing, and the top courses of chimney brick. We replace flashing with code-correct step and counter flashing, secured and sealed so the next Nor’easter doesn’t send water down the stack. Flashing repair in Hellertown usually runs $400 to $1,000 depending on roof pitch and access. Freezing weather is a safety factor on steep roofs, and we handle it with proper equipment rather than asking you to get up there.
Chimney Rebuilding and Tuckpointing
When a stack has too much damage for spot repairs, we rebuild from the roofline up or from the crown down. We use proper masonry practices, not the quick-service shortcuts that leave you with a leaning stack in five years. Tuckpointing is a lighter-touch version of repointing, often used where the joints are mostly sound but selective areas need cutting and pointing. Both are common on the older borough blocks where original chimneys have seen 80-plus winters. Rebuild work in Hellertown is the bigger investment, typically $2,500 to $6,000 for a full above-roofline rebuild, and we’ll show you the camera footage so you can see why it’s necessary. If it can be repaired without rebuilding, we’ll say that plainly.

Trusted Brands We Service in Hellertown
When we install a liner or rebuild a crown, we use products we’d put on our own homes. That means DuraFlex stainless liners for gas and oil flues, Gelco waterproofing and crown sealants, and Olympia Chimney caps and dampers. These aren’t budget parts that fail in three years; they’re what a proper Chimney Repair job should be built from. Because we keep common liner sizes and crown materials on the truck, most Hellertown jobs are done in a single visit without waiting on parts to ship.
Common Chimney Repair Problems We See in Hellertown Homes
We spend our days climbing around the old borough blocks, and the same problems show up block after block. Here’s what we actually find in Hellertown chimneys:
- Oversized coal flues now venting gas furnaces. A flue built to carry hot coal exhaust never gets hot enough with a modern 80-percent-efficient gas furnace, so draft weakens and combustion gases backdraft into the living space. This is the number one reason we install stainless liners in Hellertown.
- Cracked terra cotta liners from freeze-thaw cycling. Original clay tiles crack over decades of valley winters, and those cracks let heat and carbon monoxide into wall cavities. Camera inspection shows it every time, even when the chimney looks fine from the driveway.
- Crumbling mortar and spalled brick from water absorption. Saucon Creek’s cold air pooling means more freeze cycles than most of the Lehigh Valley, and each one works the mortar joints. Repointing caught early is cheap; full rebuilds caught late are not.
- Failing flashing from older re-roofs. If your Hellertown roof was replaced in the 1990s or 2000s, the flashing at the chimney was probably reused or poorly replaced. Water follows it straight into the house.

FAQs - Chimney Repair in Hellertown
Most need liners because they were built for coal and converted to gas or oil without being relined. The original terra cotta tiles are either cracked from decades of thermal stress or oversized for the appliance now using them, which kills the draft. The exterior brick can look perfect from the ground while the flue inside is failing. We verify with a Level 2 camera inspection and you watch the footage with us. Call (484) 603-6713 and we’ll schedule the inspection.
In most Hellertown homes, repointing just the failed joints is enough, and we’ll tell you that plainly. We cut out the damaged mortar, replace it with a compatible mix, and treat the brick for water where needed. A full rebuild is only warranted when the structural brick itself is spalled beyond repair or the stack is leaning. We show you exactly where the line is with photos and camera footage before any quote. If it needs far less than a rebuild, we say so. Call for a free estimate and we’ll give you an honest read.
Yes, and it’s the single most underused repair we do. Waterproofing with a vapor-permeable product from Gelco stops rain and snowmelt from soaking into the brick, which is exactly what causes spalling and joint failure when temperatures cycle in the Saucon Creek valley. If you’ve had mortar work twice in ten years, you likely need this. A treated chimney absorbs almost no water, so the freeze-thaw damage stops compounding. Typical cost is $500 to $900 for a Hellertown stack. Call (484) 603-6713 for a quote.
Because your new high-efficiency gas furnace is probably venting into an old, oversized coal flue that was never relined. The flue never gets warm enough to create proper draft, so the furnace works harder and exhaust lingers in the stack. Installing a correctly sized stainless liner from DuraFlex solves the draft problem and often improves combustion efficiency noticeably. We’ve seen this exact pattern on dozens of Hellertown streets, from Detweiler Avenue to the blocks around the park. Call for an inspection and we’ll show you the draft readings.
Once a year, burn or no burn. Chimneys break in the off-season too, and Hellertown’s freeze-thaw cycles do damage even when the fireplace is cold. More to the point, if your chimney has a coal-era unlined flue or cracked terra cotta liner, an occasional fire can deposit creosote onto an already compromised surface. Third-degree creosote is a glaze, and it hides behind a flue that looks fine from the outside. A yearly inspection catches this before it becomes a chimney fire. Call (484) 603-6713 and we’ll get you on the schedule while the weather’s mild.
