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.

We’ve been driving to Hellertown for over four decades. Our crews know the tight streets off Main Street, the attached twins along the railroad corridor, and the challenge of setting ladders on narrow lots where two homes share one roofline. Hellertown’s housing wasn’t built for modern trucks and modern tools, and that’s exactly why local experience matters here. When your chimney shares a wall with your neighbor’s, a sweep isn’t just about your flue. It’s about the whole stack.
Why Hearthstone Chimney Co. Is Hellertown’s Preferred Chimney Cleaning & Sweep Company
Hellertown homeowners call us because we treat the borough’s shared stacks as the unit of work, not just the flue you can see from your living room. Our Chimney Cleaning & Sweep team documents every inspection with photos you’ll see yourself, and we explain what we found in plain English before any work starts.
Our scheduling runs from our Philadelphia office, but the crews serving Hellertown live in the Lehigh Valley and know the local housing stock cold. They recognize a dual-flue coal-era stack before they set the ladder. That familiarity saves time and prevents the callbacks that happen when a sweep misses the second flue or treats a converted gas flue like it was still burning anthracite.
Calls are answered by a live person, 24 hours a day, 7 days a week. No voicemail, no callback queue. Background-checked, uniformed technicians arrive when scheduled, and most jobs finish in a single visit. The price we quote is the price on the invoice. Our 90-Day Done Right Promise covers every job in writing: if it’s not right, we make it right, no paperwork and no arguing.
Our Chimney Cleaning & Sweep Services in Hellertown
Level 1 Inspection
A Level 1 inspection is the baseline for any Hellertown chimney that’s been in regular use with no changes to the appliance or fuel type. Our technician examines the readily accessible portions of the chimney exterior, interior, and connecting appliances. In Hellertown’s older housing, we always check whether the flue we’re inspecting is one of two in a shared stack, because the condition of the cap and crown affects both sides. Level 1 inspections in Hellertown run $149 to $219 when bundled with a sweep.
Level 2 Inspection
Level 2 inspections are what most Hellertown homes actually need. This is our camera inspection: we run a high-resolution video up the full length of the flue to document every crack, gap, and creosote deposit. For Hellertown’s converted coal-to-gas chimneys, this is where we catch the undersized or deteriorated clay tile liners that were never designed for cooler, wetter gas exhaust. You’ll see the photos. We’ll give you a plain-English verdict on whether the flue is safe for continued use, needs relining, or can wait another season. Level 2 inspections in Hellertown cost $289 to $449.
Creosote Removal
Creosote builds faster in Hellertown’s older flues than homeowners expect. The borough’s converted coal chimneys often have irregular, rough clay tile surfaces and sizing mismatches that slow draft and cool gases, creating ideal conditions for creosote accumulation. First-degree creosote brushes off. Second-degree needs rotary chains. Third-degree, or glazed creosote, requires chemical treatment and mechanical removal. We price creosote removal in Hellertown from $189 to $329 for standard buildup, with third-degree cases running $349 to $499 depending on flue length and severity. We use professional-grade equipment and never leave a flue partially cleaned.
Soot Removal
Soot removal sounds simple until you’re working in a flue that’s been accumulating fine particulate for thirty years because the last owner never swept. In Hellertown’s pre-1960 homes, we regularly find soot deposits that have partially blocked the flue, reducing draft and increasing the risk of carbon monoxide spillage. Our soot removal service includes full debris extraction and a post-cleaning draft test to confirm the flue is drawing properly before we sign off.
Annual Sweep
The National Fire Protection Association recommends annual inspection and cleaning for all wood-burning systems. In Hellertown, we’d extend that to any home with a pre-1960 chimney, regardless of fuel type, because the structural condition of these stacks degrades predictably with age and freeze-thaw exposure. Our annual sweep service in Hellertown includes the Level 1 inspection, full flue cleaning, and a written condition report. We call you when it’s due next year.
Fireplace Cleaning
Fireplace cleaning in Hellertown often reveals more than ash. We find bird nests in uncapped flues, deteriorated firebrick, and smoke stains indicating drafting problems. Because many Hellertown fireplaces share a chimney structure with a furnace or water heater flue, we inspect both flues even when you only called about the hearth. Cross-contamination between flues is a real problem in attached housing, and we won’t sign off on a cleaning until we’ve verified both sides of the stack.

Trusted Brands We Service in Hellertown
We don’t use builder-grade substitutes. For relining, repairs, and component replacement in Hellertown, we specify DuraFlex stainless steel liners, HeatShield cerfractory resurfacing systems, and Olympia Chimney caps and accessories. These are the brands that professional sweeps specify when the job has to last. We stock common sizes and fittings locally, so most Hellertown repairs don’t wait on shipping. If your inspection turns up a cracked liner or failed crown, we can often schedule the repair for the same visit, with parts that match your stack’s original construction intent.
Common Chimney Cleaning & Sweep Problems We See in Hellertown Homes
- Shared dual-flue stacks in twin homes. One masonry chimney serving two households is standard in Hellertown’s core neighborhoods. Sweeping only your flue and ignoring your neighbor’s side leaves debris, cross-contamination, and shared-cap failures unaddressed. We inspect both flues and document the full stack condition.
- Converted coal flues with deteriorated clay tile liners. The original masons sized these flues for 1200°F coal exhaust. Modern gas appliances run cooler and wetter, and the original liners are now 70 to 100 years old. Cracked, shifted, or missing tiles are the norm, not the exception, in Hellertown’s 1910s to 1950s housing.
- Freeze-thaw damage to crowns and mortar joints. Hellertown sits in the lower Saucon Valley where cold air pools and freeze-thaw cycling extends well into March. Spalled brick, open mortar joints, and cracked crowns are nearly universal on pre-1960 stacks. Moisture intrusion accelerates liner deterioration and can make a routine sweep into a repair job.
- Improperly sized flues for current appliances. A flue that was correct for a coal furnace in 1925 is almost certainly wrong for a 90% efficient gas boiler today. Undersized flues backdraft. Oversized flues cool too quickly, condensing moisture and accelerating corrosion. Our Level 2 inspection catches these mismatches before they become safety hazards.

FAQs - Chimney Cleaning & Sweep in Hellertown
No, your sweep covers your flue only, but we inspect both flues and the shared cap and crown before we sign off. On a twin home off Main Street in Hellertown’s core, our tech swept the furnace flue and pulled first-degree creosote and soot, then found the shared chimney cap cracked and the crown spalling enough that debris was dropping down the neighbor’s fireplace flue. We pulled both flues, sealed the cap, and flagged the shared stack so the next sweep isn’t a callback - a pattern we see on nearly every block of 1910s to 1950s twins here. If the neighbor’s flue needs cleaning, we’ll document it and you can share the report. Call (610) 632-1394 for an exact quote.
Because most Hellertown chimneys were built for coal, converted to oil, then converted to gas, and the original clay tile liner is now 70 to 100 years old. A Level 1 sweep cleans what you can see. A Level 2 camera inspection shows us what you can’t: cracked tiles, missing mortar, gaps between flue sections, and creosote buildup hidden behind offsets. In Hellertown’s housing stock, we find actionable defects in about two-thirds of Level 2 inspections. The photos are yours. The verdict is plain English. Call (610) 632-1394 to schedule.
First-degree creosote is fluffy and black, like soot. Second-degree is crunchy and tar-like, often forming ribbons or flakes. Third-degree, or glazed creosote, is hard, shiny, and black as obsidian - it looks like enamel baked onto the flue wall. In Hellertown’s older, rough-surfaced clay tile flues, we see more second and third-degree buildup than in modern smooth-metal liners because the irregular surface traps condensate. Glazed creosote is a fire hazard and requires chemical treatment plus mechanical removal. Call (610) 632-1394 if you’re unsure what you’re seeing.
Yes. Hellertown sits in the lower Saucon Valley where cold air drains and lingers, and freeze-thaw cycling continues into March. Water enters cracked crowns and open mortar joints, expands when it freezes, and opens those cracks wider. By spring, a small crown crack can become a spalled surface and failed mortar joints that let water into the flue year-round. We check crown and mortar condition on every Hellertown inspection because the local climate makes this damage predictable. Call (610) 632-1394 for a free condition check.
Yes, if your chimney is pre-1960 or serves any combustion appliance. In Hellertown, many homeowners think their gas furnace or water heater flue doesn’t need attention because there’s no visible soot. But these converted coal flues often have deteriorated liners, blocked caps from shared-stack debris, and moisture damage from freeze-thaw cycling that has nothing to do with how much you burned. An unswept, uninspected flue is a carbon monoxide risk and a fire risk regardless of use. Call (610) 632-1394 for a free estimate - inspections are the only way to know your stack’s true condition.
