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 Allentown’s Preferred Fireplace Services Company
Allentown homeowners call us because we document what we find and explain it in plain English. Every Level-2 inspection ends with photos you can see and a written verdict, not a vague verbal summary. If we recommend a repair, we show you exactly why.
Our 90-Day Done Right Promise means the job is backed in writing, no arguing. If it’s not right, we come back. That matters in a city where many residents have been in their homes for twenty-plus years and intend to stay. They want the repair done once, correctly, so they never think about it again.
A live person answers our phones every hour of every day. No voicemail, no callback queue. When you’re trying to schedule before burning season or you’ve noticed water staining around your firebox, that accessibility matters.
We also understand Allentown’s unique chimney architecture. The shared party-wall flues in row homes from the 1890s to 1940s require a different inspection approach than detached suburban chimneys. Our Fireplace Services team has coordinated repairs across property lines on the South Side and East Side when one deteriorating flue affected multiple households.
Our Fireplace Services in Allentown
Gas Fireplace Service
Gas fireplace service in Allentown runs $180-$320 for a standard seasonal tune-up, including burner cleaning, pilot adjustment, and safety-check of the gas valve and thermocouple. Most Allentown gas fireplaces were converted from original coal or oil systems, leaving flues that are oversized for modern low-BTU appliances. These cold, wet flues trap corrosive condensate. During a gas fireplace service call on the 700 block of Maple Street on Allentown’s South Side, our tech opened the firebox of a converted gas fireplace and found water staining and crumbling mortar, with the damper rusted shut. A Level-2 inspection revealed the party-wall shared flue had no flue liner and was oversized for the modern gas appliance, allowing corrosive condensate to eat the tile. We installed a HeatShield liner sized to the appliance, rebuilt the firebox and damper, and coordinated with the neighbor whose furnace also vents into the same stack so neither household’s heating was left unvented.
Wood Burning Fireplace
Wood burning fireplace inspection and sweeping in Allentown costs $250-$380, with repairs to the firebox or smoke chamber additional. The tall masonry stacks common in Allentown’s 1890-1945 housing stock draw well when maintained, but the Lehigh Valley’s harsh freeze-thaw cycling spalls exposed brick and mortar. Annual inspection is essential. We use Gelco and Olympia Chimney professional-grade components for rebuilds and repairs.
Fireplace Insert
Fireplace insert installation in Allentown ranges from $2,800-$4,500 depending on liner requirements and whether the existing flue needs modification. In Allentown row homes with shared party-wall chimneys, insert sizing must account for the neighbor’s appliance venting into the same stack. We measure the full flue system, not just your unit’s portion, before recommending an insert. No installation proceeds without a camera inspection and written sizing report.
Damper Repair
Damper repair in Allentown typically costs $280-$550. Dampers in converted Allentown fireplaces rust shut from condensate exposure or warp from decades of heat cycling. A stuck damper wastes energy and can allow smoke or carbon monoxide to back up into living space. We stock replacement dampers from Famco and Copperfield for fast turnaround, and most repairs are completed in one visit.
Fireplace Conversion
Converting a wood or coal fireplace to gas in Allentown runs $1,800-$3,200. The critical issue in this market is flue sizing. Original coal flues are often 12×12 inches or larger, while modern gas appliances need a properly sized, insulated liner to maintain adequate draft and prevent condensate damage. We never install a conversion without a Level-2 inspection and liner sizing calculation. The oversized, unlined flues common in Allentown’s converted housing stock will destroy a new gas insert within seasons if not addressed.
Firebox Repair
Firebox repair in Allentown costs $450-$1,200 depending on whether we’re patching refractory panels or rebuilding with new firebrick. Water intrusion from failed chimney crowns is the usual culprit in Allentown’s older masonry. We document the damage with photos before touching a brick, and we show you the source of the leak so you understand why the repair is necessary.
Trusted Brands We Service in Allentown
We work exclusively with professional-grade materials from DuraFlex, HeatShield, Gelco, Olympia Chimney, Famco, and Copperfield. No builder-grade substitutes. For Allentown customers, this means we stock common dampers, liners, and crown repair materials locally, so we’re not ordering parts and making you wait. A typical damper or firebox repair on the East Side or in Jordan Heights is done same-visit because the correct Famco or Copperfield component is on the truck. When a HeatShield liner is specified for a converted gas flue, we size and install it to the appliance manufacturer’s exact BTU rating, not guesswork.
Common Fireplace Services Problems We See in Allentown Homes
- Cross-contamination in shared party-wall chimneys. A shared party-wall chimney serving two or three row homes means one neighbor’s cracked flue tile allows carbon monoxide and corrosive condensate to migrate into an adjoining unit’s fireplace. We routinely find cross-contamination that each owner assumed was only their problem. This requires coordinating inspection access and repair sequencing with adjacent households.
- Cold, wet flues from coal-to-gas conversions. The coal-to-oil-to-gas conversion cycle left Allentown’s original flues oversized and unlined for modern low-BTU gas appliances, so they run cold and wet, trapping creosote and moisture that silently degrade mortar and tile from the inside. A gas fireplace that smells musty or produces weak draft often has this underlying condition.
- Freeze-thaw spalling on tall masonry stacks. Allentown sits in the Lehigh Valley floor, where cold air pools in winter and intensifies freeze-thaw cycling compared to surrounding hillside communities. This accelerates spalling of exposed brick and mortar on chimney stacks, making annual inspection and tuckpointing a near-constant need for the older masonry stock.
- Deferred crown and flashing repairs due to difficult roof access. Because roof access between attached row homes is narrow and awkward, minor crown and flashing failures are frequently deferred until water is already inside the flue. By the time staining appears on the firebox, the damage often extends to the smoke chamber and damper.

FAQs - Fireplace Services in Allentown
It can be. Shared party-wall chimneys are common in Allentown’s South Side, Jordan Heights, and center-city neighborhoods, and a crack or missing flue tile in one unit can allow carbon monoxide or corrosive condensate to migrate into an adjoining flue. We inspect the entire shared stack with a camera and document any cross-contamination. If repair is needed, we coordinate with your neighbor so neither household’s venting is compromised. Call (610) 632-1394 to schedule a Level-2 inspection.
The original coal flue is almost certainly oversized and unlined for your modern gas appliance. These cold, wide flues run below the dew point, trapping moisture and corrosive condensate that degrades mortar and produces that musty odor. We see this constantly in Allentown’s converted 1890-1945 housing stock. A properly sized, insulated liner - typically HeatShield or DuraFlex - solves the draft and moisture problem permanently. Call (610) 632-1394 for an exact quote; estimates are free.
Annual Level-2 inspection is the minimum for Allentown’s masonry chimneys. The Lehigh Valley’s intensified freeze-thaw cycling accelerates spalling and mortar deterioration compared to hillside communities nearby. For gas conversions in oversized flues, we also recommend inspection if you notice any change in draft, odor, or appliance performance. Call (610) 632-1394 to schedule before burning season.
Yes, in most cases. Damper repair and firebox rebuilding are localized repairs that don’t require chimney replacement. We replace rusted or warped dampers with correctly sized components from Famco or Copperfield, and we rebuild fireboxes with proper refractory materials. The key is identifying and fixing the water source - usually a cracked crown or failed flashing - so the repair lasts. Call (610) 632-1394 for a camera inspection and written repair scope.
Check for hairline cracks in the crown concrete, gaps where the crown meets the brick stack, and any separation between flashing and roofline. On Allentown’s tall masonry chimneys, these minor entry points become major water intrusion paths after freeze-thaw cycling. Roof access between row homes is awkward, so many homeowners defer this check. We include crown and flashing assessment in every Level-2 inspection, with photos. Call (610) 632-1394 to schedule; estimates are free.
