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.
Fast, Reliable Chimney Cleaning & Sweep Across Allentown
A professional chimney cleaning and sweep in Allentown typically costs between $180 and $320 for a standard Level 1 service, with Level 2 camera inspections running $320 to $480 depending on roof access and flue complexity. Most sweeps on detached homes in Allentown’s West End or Trexler Park take about 90 minutes. For the attached row homes that make up much of the South Side and Jordan Heights, where shared party-wall chimneys complicate access, we allow extra time to coordinate proper containment and documentation.
We’ve been dispatching crews to Allentown from our Philadelphia office for decades through Allentown Fireplace Services. Russell Haines built Hearthstone Chimney Co. on the principle that a homeowner should see what we see before any work is approved. That matters especially here, where one chimney can serve two or three households and a missed crack in a shared flue doesn’t just affect your living room. It can shut down your neighbor’s heat too. Call (610) 632-1394 - a live person answers, every hour of every day.
Why Hearthstone Chimney Co. Is Allentown’s Preferred Chimney Cleaning & Sweep Company

We’ve documented condemned flues on South 4th Street, restored party-wall liners in Jordan Heights, and replaced crowns on the tall stacks of the East Side where freeze-thaw damage from Lehigh Valley winters accelerates spalling.

Our Chimney Cleaning & Sweep Services in Allentown
Level 1 Inspection
A Level 1 inspection covers readily accessible portions of the chimney, fireplace, and flue - the standard annual check for Allentown homeowners with straightforward systems and no recent changes. For the detached colonials and Cape Cods in Allentown’s West End, this is often sufficient. We check structural soundness, creosote accumulation, and basic clearances. Takes about an hour. If we find anything that warrants a closer look, we’ll show you the photo and explain why before recommending a Level 2.

Level 2 Inspection
This is where our Chimney Cleaning & Sweep team spends most of its time in Allentown. A Level 2 includes everything in Level 1 plus camera inspection of the internal flue surfaces, attic and basement access where reachable, and detailed documentation of liner condition, mortar joints, and hidden breaches. For Allentown’s row homes with shared party-wall chimneys, this isn’t optional. It’s essential. We’ve found separated flue liners, deteriorated smoke chamber parging, and cross-flue contamination that a visual-only inspection would miss entirely. You get photos you can see and a plain-English verdict. No jargon, no scare tactics. Just the facts, documented like an engineer, explained like a craftsman.

Creosote Removal
Allentown’s older flues - especially the oversized, unlined ones converted from coal to oil or gas - run cooler than modern systems and collect creosote differently. Third-degree glazed creosote, the hard, tar-like deposit we find in many South Side and Jordan Heights chimneys, can’t be brushed out with standard tools. It requires rotary mechanical removal or chemical treatment. We’ve restored drafting to furnaces that were choked to 40% efficiency by glaze buildup. The work is messy. We contain it properly, especially critical when roof access means working over your neighbor’s property line on a tight row-home block.

Soot Removal
Soot accumulation in gas and oil systems is different from wood-burning creosote - finer, more acidic, and equally capable of restricting draft when it packs into elbows and offsets. In Allentown’s converted flues, where the original coal-era dimensions don’t match modern appliance output, soot combines with corrosive condensate to accelerate deterioration. We remove it with powered brushes and HEPA containment, then document what the flue walls look like underneath. Sometimes the news is good. Sometimes it isn’t. Either way, you’ll see what we see before any decision.

Annual Sweep
The National Fire Protection Association recommends annual inspection; for Allentown’s housing stock, we agree strongly. Freeze-thaw cycling in the Lehigh Valley is harder on exposed chimney brick than in surrounding hill towns. Shared flues mean your maintenance affects your neighbor’s safety. And the fuel conversions that most of these chimneys have been through - coal to oil, oil to gas, sometimes back again - created compatibility problems that only regular monitoring catches before they become emergency repairs. We schedule annual sweeps with reminder calls before burning season. Done right, and we stand behind it.

Fireplace Cleaning
For homeowners in Allentown who still burn wood - more common in the detached homes west of 19th Street than in the row-home core - fireplace cleaning includes firebox parging check, damper operation, smoke shelf clearing, and exterior crown assessment. We use professional-grade materials from Gelco service in Allentown and Copperfield for any repair work. No builder-grade substitutes.

Trusted Brands We Service in Allentown
We stock parts and materials from Olympia Chimney, Famco, Gelco, and Copperfield - brands that hold up to Allentown’s freeze-thaw cycles and corrosive condensate conditions. When a Level 2 inspection calls for liner repair or replacement, we’re not waiting on a distributor shipment. That means faster turnaround for Allentown homeowners, especially important when a condemned flue in a shared chimney has left multiple households without heat. Our technicians carry HeatShield and DuraFlex inventory on the truck for same-visit restoration when the scope allows.
Common Chimney Cleaning & Sweep Problems We See in Allentown Homes
- Shared party-wall flue failure. On tight row-home blocks in the South Side and Jordan Heights, one crumbling chimney can ground heating systems for two or three adjoining families simultaneously. We coordinate across property lines to isolate, repair, and verify safe drafting for each household before anyone’s furnace goes back online.
- Oversized, unlined flues trapping condensate. Allentown’s early 20th-century chimneys were built for coal combustion, then converted to oil or gas as Bethlehem Steel declined. Those flues are chronically undersized for modern appliance BTU output. Corrosive condensate pools on smoke chamber shelves and eats tile and mortar faster than in newer suburban stock.
- Freeze-thaw spalling on tall exposed stacks. Cold air pools in the Lehigh Valley floor, intensifying freeze-thaw cycling compared to hillside communities like Emmaus or Salisbury Township. The result: flaking brick faces, deteriorated mortar joints, and water infiltration that accelerates everything else.
- Cross-contamination through breached smoke chambers. When one household’s appliance vents into a shared stack, flue gases or condensate can migrate into a neighbor’s flue through gaps in the separating masonry. We’ve documented carbon monoxide potential from this condition. It’s rare but real, and it only gets found with camera inspection.

FAQs - Chimney Cleaning & Sweep in Allentown
Each household is typically responsible for the flue that serves their own appliance, but the shared masonry shell is a common element that affects everyone. In practice, we often need access agreements to inspect or repair properly, and we coordinate with adjoining owners when a party-wall condition threatens multiple units. We’ve done this on South Side blocks where one condemned liner affected three households. Call (610) 632-1394 and we’ll walk through your specific situation - estimates are free.
Allentown’s dense row homes feature oversized flues converted from coal to oil or gas, running cooler and wetter than modern systems. That corrosive condensate, combined with decades of deferred maintenance on shared structures, accelerates tile and mortar deterioration at a rate uncommon in Whitehall’s newer detached housing. The Lehigh Valley floor’s intensified freeze-thaw cycling doesn’t help. A Level 2 inspection shows exactly what condition your liner is in. Call for a camera evaluation - (610) 632-1394.
The only reliable way is a Level 2 camera inspection with smoke testing. Visible signs can include unusual odors, soot patterns that don’t match your own appliance use, or draft problems that worsen when your neighbor’s system cycles on. On a block of attached brick row homes off South 4th Street, we documented exactly this: back-drafting condensate from one unit glazing the neighbor’s flue liner. After HeatShield restoration and coordinated verification, both households drafted properly again. If you suspect cross-contamination, call (610) 632-1394 - this is not a DIY diagnosis.
Yes, especially in Allentown. Annual inspection is about more than creosote from wood burning. Gas and oil appliances produce corrosive condensate that degrades liners and mortar year-round. Freeze-thaw damage progresses regardless of how often you light a fire. And in shared chimneys, your neighbor’s use affects your flue’s condition. The NFPA 211 standard is annual inspection, not annual burning. Our $89 Seasonal Tune-Up makes the baseline check accessible. Call (610) 632-1394 to schedule.
First-degree creosote is light, fluffy, and brushes out easily - what you’d find in a well-maintained, properly sized modern flue. Third-degree glazed creosote is a hard, tar-like, nearly impermeable layer that forms when flue gases condense on cool, oversized surfaces. It’s the standard finding in Allentown’s converted coal flues. Glaze insulates the flue, reduces draft, and becomes a significant fuel load if ignited. Removal requires rotary mechanical tools or chemical treatment, not standard brushing. We assess creosote type during every Level 2 inspection and price accordingly before work begins.
