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.

Why Hearthstone Chimney Co. Is Hellertown’s Preferred Fireplace Services Company
Hellertown homeowners don’t need a salesman. They need a sweep who will look them in the eye and tell them exactly what their chimney needs, what it doesn’t, and what it will cost. That’s what we’ve built Hearthstone Chimney Co. on since 1984.
Our reputation here rests on documentation. Every inspection ends with photos you can see and a plain-English verdict. No jargon, no scare tactics, no pushing work that can wait. If your firebox has minor spalling and your liner is sound, we’ll say so. If your shared flue stack is pulling exhaust from your neighbor’s appliance, we’ll show you the camera footage and explain the repair.
Calls are answered by a live person, 24 hours a day, 7 days a week. Not a voicemail, not a callback queue. Our technicians are background-checked, uniformed, and carry the professional-grade materials to complete most jobs in one visit: DuraFlex liners, HeatShield resurfacing systems, Famco caps and dampers. The price we quote is the price on the invoice. And everything we do is backed by our 90-Day Done Right Promise - in writing, no arguing.
We know the difference between a home on Main Street and one down by the Saucon Creek. We know which blocks have the shared double-flue stacks, which roofs are steep enough to require extra rigging, and which chimneys were last touched during the 1970s gas conversion boom. That local knowledge saves time and prevents misdiagnosis.
Our Fireplace Services in Hellertown
Gas Fireplace Service
Gas fireplaces in Hellertown’s converted worker homes often struggle because they’re vented through flues never designed for them. The original coal furnace needed a massive flue to move high-temperature exhaust. Your 30,000-BTU gas insert doesn’t produce enough heat to establish proper draft in that oversized chamber. The result is condensation, corrosion, and eventually a burner that won’t stay lit. We inspect the flue sizing, check for proper venting configuration, and can install a DuraFlex liner sized specifically for your appliance’s output. Done right - and we stand behind it.

Wood Burning Fireplace
Wood burning in a Hellertown row home demands extra attention to the flue condition and the neighbor connection. If you share a masonry stack, your draft is only as good as the liner integrity on both sides of the wall. We perform Level-2 camera inspections to verify that your flue is isolated, intact, and properly capped. We also evaluate whether your fireplace is actually suitable for wood burning given its age and construction, or whether an insert would be safer and more efficient. No guesswork. Photos you can see, a plain-English verdict.

Fireplace Insert
This is one of our most common requests in Hellertown, and for good reason. A properly sized insert turns an inefficient, oversized masonry fireplace into a controlled heat source without the draft problems of an open hearth. In borough-core row homes, inserts also reduce the volume of air moving through the flue, which cuts condensation and helps prevent the tar-like third-degree creosote that plagues oversized coal-era chimneys. We size the insert to the space, install a matching DuraFlex liner, and handle all combustion-air requirements. Most installations finish in one day.

Damper Repair
A failed damper in a Hellertown home is more than wasted heat. In attached housing with shared flues, a damper that won’t seal can allow odors, moisture, and in worst cases exhaust gases to migrate between units. We repair and replace throat dampers, top-sealing dampers, and the damaged frames that prevent proper closure. If your fireplace smells like a neighbor’s heating fuel, the damper is one of the first things we check. We stock Famco and Copperfield dampers for fast turnaround.

Firebox Repair
The firebox takes the direct heat, and in Hellertown’s century-old homes it’s often cracked, spalled, or missing mortar at the rear wall. We rebuild with refractory materials rated for the temperatures your appliance produces, not the quick-patch cements some operators use. For minor cracking, HeatShield resurfacing can restore a sound surface without full rebuild. We photograph the damage, explain the repair, and give you a fixed price before we start.

Fireplace Conversion
Converting wood to gas in a Hellertown row home requires careful evaluation of the flue, the shared-stack configuration, and combustion air supply. We do not perform conversions that compromise safety or violate code. If your chimney cannot safely vent a gas appliance, we’ll tell you plainly and discuss alternatives - sometimes a direct-vent insert, sometimes repair before conversion. No surprises on the bill, and no work we can’t stand behind.

Trusted Brands We Service in Hellertown
We don’t use builder-grade substitutes. Our trucks carry professional-grade materials from DuraFlex, HeatShield, Famco, and Copperfield - the brands that other sweeps in the Lehigh Valley often have to special-order. That means faster repairs for Hellertown homeowners, especially when we’re addressing the shared-flue and condensation problems unique to this market. If your cap blew off in a winter storm or your liner needs replacement, we likely have the right part on the truck. If we don’t, our Philadelphia office coordinates same-day pickup. A square deal: no surprises on the bill.
Common Fireplace Services Problems We See in Hellertown Homes
- Cross-contamination in shared flue stacks. In brick row homes near the borough core, a cracked terra cotta liner or missing chimney cap can allow your neighbor’s appliance exhaust to backdraft through shared masonry into your living space. We identify this with camera inspection and seal the breach with proper liner installation and cap replacement.
- Third-degree creosote from oversized flues. Coal-era chimneys now venting low-BTU gas inserts or occasional wood fires run too cool. Moisture condenses on liner walls and combines with combustion byproducts into a tar-like, highly flammable deposit that standard brushing won’t remove. We treat this with mechanical removal and chemical treatment, then resize the flue if needed.
- Freeze-thaw damage to crowns and mortar joints. Hellertown’s position in the Saucon Creek valley creates cold air pooling and aggressive freeze-thaw cycling. Soft mortar crumbles. Crown cracks widen. Water enters and masquerades as a draft problem. We repoint with proper mortar, pour new crowns, and install flashing that sheds valley moisture.
- Damper failure causing heat loss and odor migration. In attached homes, a damper that won’t fully seal doesn’t just waste energy. It creates a pathway for air pressure differences to move smells and moisture between units. We repair or replace with positive-sealing top dampers where appropriate.

FAQs - Fireplace Services in Hellertown
Yes, if the flue liner is cracked or the chimney cap is missing or improperly installed, exhaust from your neighbor’s appliance can migrate through shared masonry into your living space. This is a documented hazard in Hellertown’s coal-era attached housing, where double-flue stacks were never designed for modern sealed-combustion appliances. We identify cross-contamination with Level-2 camera inspection, then isolate the flues with proper liner installation and cap replacement. If you’re smelling heating fuel odors when your neighbor’s system runs, call (610) 595-5754 - this is not a problem that improves with time.

That tar-like odor is almost certainly third-degree creosote, and in Hellertown it usually forms in oversized coal-era flues that now vent low-output gas inserts or see only occasional wood fires. The flue runs too cool. Moisture condenses. Combustion byproducts polymerize into a thick, sticky, highly flammable deposit that standard brushing cannot remove. We see this constantly in borough-core homes built between 1910 and 1955. Mechanical removal with specialized equipment, followed by chemical treatment and proper flue sizing, solves it. Call for an inspection - estimates are free.

The National Fire Protection Association recommends annual inspection for all chimney systems, and in Hellertown we strongly agree given the age of the housing stock and the freeze-thaw stress on masonry. Homes with shared flues, converted coal-era chimneys, or any history of water intrusion should consider inspection before each burning season. We document every inspection with photos and a written verdict so you can make informed decisions about what to address now and what can wait. Schedule yours at (610) 595-5754.

First-degree creosote is flaky, dry, and brushes off easily - typical of hot, fast-burning fires in properly sized flues. Third-degree creosote is a thick, tar-like, highly concentrated fuel that adheres to liner walls and requires mechanical or chemical removal. It matters enormously in Hellertown because the borough’s oversized coal-era flues, now venting low-BTU appliances, create the cool, moist conditions where third-degree creosote forms prolifically. It’s the most dangerous type for chimney fires. If you suspect this condition, call (610) 595-5754 for a camera inspection - we can show you exactly what your liner walls look like.

Sometimes, but only after proper evaluation of the flue sizing, liner condition, and shared-stack configuration. We do not perform conversions that rely on an unsafe shared flue or an oversized unlined chimney. In many Hellertown row homes, the best path is a direct-vent gas insert with its own sealed combustion system, eliminating dependence on the existing flue entirely. We’ll inspect your specific configuration, explain what will work and what won’t, and give you a fixed price for a safe, code-compliant installation. Call (610) 595-5754 to schedule - estimates are free, and we offer free second opinions on any written estimate you’ve received elsewhere.
We were called to a brick row home near the borough core where the homeowner reported a kerosene-like odor in the living room whenever the neighbor’s gas furnace kicked on. Our tech performed a Level 2 inspection with a camera and found the shared flue stack had a cracked terra cotta liner and a disconnected neighbor’s appliance connector, allowing flue gases to migrate through the shared masonry. We repaired the firebox, installed a HeatShield liner in the affected flue, and replaced the chimney cap and damper to restore proper draft and stop the cross-contamination.
