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 working in Hellertown long enough to know the borough’s chimneys aren’t like the ones in newer Lehigh Valley subdivisions. The pre-WWII worker housing off Main Street, the attached twins along East Depot Street, and the brick rows near the old Bethlehem Steel corridor were built with coal-burning fireplaces and shared masonry stacks that now vent oil furnaces, gas water heaters, and wood stoves they were never designed to handle. That history lives in your flue. Our Chimney Cleaning & Sweep team understands what these chimneys need because we’ve cleaned, inspected, and repaired hundreds of them across the Saucon Valley.

We know Hellertown’s streets, its rooflines, and its chimneys. The narrow access between attached twins. The steep pitches on Saucon Valley row homes. The way South Mountain’s cold air pools down into the borough and accelerates freeze-thaw damage on crowns and flashing. That local knowledge saves time and prevents mistakes.
Our Chimney Cleaning & Sweep Services in Hellertown
Level 1 Inspection
A Level 1 inspection is the baseline annual check for Hellertown homeowners who burn wood or run their heating appliance regularly through the Lehigh Valley’s long season. We examine the readily accessible portions of your chimney structure, flue, and connection - looking for creosote buildup, obstructions, and basic structural soundness. For many Hellertown row homes and twins with straightforward single-appliance flues, this is sufficient. Cost: $189-$249.
Level 2 Inspection
This is where we spend most of our time in Hellertown. A Level 2 inspection includes everything in Level 1 plus a full camera scan of the interior flue, inspection of attics and crawl spaces, and documentation with photos you can see. It’s required when you’re buying or selling a home, after a chimney fire, or when switching fuel types - and it’s essential for any Hellertown property with a shared stack or a flue that was converted from coal to oil or gas. The camera reveals cracked clay tiles, missing mortar, and creosote glazing that a visual check simply cannot catch. Cost: $289-$419. Every Level 2 ends with a plain-English verdict and photo report.
Creosote Removal
Hellertown’s long heating season - October through April, often longer in the Saucon Valley’s cold pockets - means creosote accumulates steadily. First-degree creosote brushes off easily. Third-degree creosote, the hard, glazed tar-like coating we see in wood stoves and slow-burning fireplaces, requires rotary cleaning with professional-grade equipment and chemical treatment. We remove it completely. Cost: $249-$389 depending on severity and flue length.
Soot Removal
Soot buildup from oil and gas appliances is different from wood creosote - finer, more acidic, and capable of corroding metal components and staining masonry. In Hellertown’s older homes with oversized flues and marginal draft, soot can accumulate in the smoke chamber and damper area, restricting airflow and causing odors. We remove it with HEPA-contained equipment that protects your home’s air quality. Cost: $189-$289.
Annual Sweep
The National Fire Protection Association recommends annual inspection and cleaning for all wood-burning systems. In Hellertown, with its heavy reliance on supplemental wood heat and the cross-contamination risks of shared stacks, we treat annual service as non-negotiable. Our seasonal sweep includes full debris removal, flue brushing, firebox cleaning, and a basic structural check. Cost: $189-$249. The $89 Seasonal Tune-Up offer applies for qualifying systems.
Fireplace Cleaning
Fireplace cleaning addresses the firebox, smoke chamber, damper, and hearth area - the parts you see and the parts you don’t. In Hellertown’s coal-era fireplaces, smoke chambers are often corbeled brick with rough surfaces that trap creosote and restrict draft. We clean and assess these components as part of integrated service. Cost: $149-$219 as standalone, or included with full sweep.

Trusted Brands We Service in Hellertown
We stock professional-grade materials from DuraFlex, HeatShield, Gelco, and Copperfield - the brands we trust for liner systems, crown repair, and chimney cap installation. For Hellertown homeowners, that means faster turnaround. When a Level 2 inspection reveals a cracked liner in a shared stack or spalling brick from Saucon Valley freeze-thaw, we don’t order parts and make you wait two weeks. Our trucks carry the components to complete most repairs in the same visit. No return trip, no second day off work.
Common Chimney Cleaning & Sweep Problems We See in Hellertown Homes
- Shared-stack cross-contamination between attached units. On a block of attached brick twins off East Depot Street, our tech found a shared stack where one unit’s oil furnace flue had a failing clay-tile liner; exhaust was staining the neighbor’s smoke chamber and setting off a CO alarm. We swept both sides of the stack, set a HeatShield liner on the compromised side, and installed a stainless chimney cap to stop the cross-draft. The neighbor’s draft improved the same day, and both units passed a Level 2 inspection with documentation for the shared-stack agreement.
- Coal-era flues improperly sized for modern appliances. Hellertown’s oversized, unlined masonry stacks - built for coal furnaces - draft poorly with today’s gas and oil equipment. Creosote builds up in the wrong places. Carbon monoxide risks increase. A Level 2 camera inspection reveals the mismatch.
- Freeze-thaw damage from Saucon Valley cold pooling. South Mountain’s geography traps cold air in Hellertown, creating aggressive freeze-thaw cycling that spalls brick, cracks crowns, and lifts flashing. Water enters the shared stack and damages both units’ mortar joints. We catch this early during annual service.
- Heavy third-degree creosote from extended wood-burning seasons. Hellertown homeowners burn longer than the calendar suggests. The Lehigh Valley’s lingering cold means stoves run into April. That extended use produces glazed creosote that standard brushing won’t remove. Our rotary system handles it.

FAQs - Chimney Cleaning & Sweep in Hellertown
Check your basement where the flue pipes enter the masonry - if two appliances from adjacent units connect to the same brick stack, you share a chimney. In Hellertown’s pre-WWII worker housing, this is common. A Level 2 camera inspection confirms the internal flue separation and identifies any cracks or gaps allowing cross-contamination. Call (610) 756-1504 to schedule - estimates are free.
Your flues are not fully separated, or a liner has cracked, allowing exhaust to migrate between units. In Hellertown’s shared masonry stacks, this is a documented hazard we encounter regularly. We inspect both sides, identify the breach with camera evidence, and repair it with proper isolation - often with a stainless liner on one or both flues. Both units need coordinated service. Call (610) 756-1504 to arrange joint scheduling.
Yes. Six months of regular wood burning in the Lehigh Valley produces enough creosote to warrant annual removal, especially in Hellertown’s older, often-oversized flues where draft is marginal and creosote deposits unevenly. The NFPA recommends annual inspection for all wood-burning systems regardless of burn duration. Skipping a year risks chimney fire and carbon monoxide exposure. Call (610) 756-1504 to book your annual service.
First-degree creosote is flaky, sooty, and brushes off easily with standard equipment - common with dry hardwood and hot fires. Third-degree creosote is hard, glazed, and tar-like, requiring rotary mechanical cleaning and sometimes chemical treatment to remove safely. We see third-degree buildup frequently in Hellertown’s slow-burning stoves and in flues with poor draft from oversized, unlined stacks. Both types are fire hazards; third-degree is significantly more dangerous. Call (610) 756-1504 for a Level 2 inspection to assess your creosote condition.
Yes. Our technicians are equipped for Hellertown’s tight rooflines and steep pitches. We use ladder stabilizers, rope-and-harness systems, and ground-based rotary equipment where roof access is impractical. Safety is non-negotiable - we don’t attempt unsafe access, and we’ll explain alternative methods before we start. Most Hellertown row homes and twins are fully serviceable. Call (610) 756-1504 to discuss your specific access situation.
