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.

AfterHeatShield Chimney Cleaning in Bangor, PA | Hearthstone Chimney Co.
Bangor Chimney Cleaning & Sweep with HeatShield liner restoration typically runs $280-$550 for a full TherMix resurfacing or CeCure joint repair, with most Level 2 inspections completed in a single visit. What makes our HeatShield work different here is the slate. Bangor’s original quarry-worker housing stock carries century-old slate roofs with flashing repairs that often funnel water straight into the masonry, undermining liner bonds from above. We pull that water intrusion out by the root before we resurface anything. Call us at (610) 609-7634 for a free estimate - we’ll look at the flashing, the flue, and the whole picture.
We’ve been working chimneys across the Slate Belt for over 42 years. Russell Haines, our owner, learned this trade at Los Angeles Trade-Technical College, where the instructors drilled one lesson into every student: if you can’t show the homeowner what you found, you didn’t finish the job. That worn inspection mirror on his truck dash has seen more than a thousand flues. It still comes out on every Bangor call.
Why Bangor Residents Choose Us for HeatShield Service
We know these chimneys. Not in the abstract - in the specific. The quarry-worker rowhouses along Market Street, the converted coal fireboxes in the Bangor Borough Historic District, the tall exposed flues catching Blue Mountain wind. Russell Haines has spent the better part of two decades putting hands on Bangor chimneys, and our crew has pulled HeatShield liners from flues that started life burning anthracite and now burn cordwood.
We are an independent HeatShield service provider. Not authorized. Not sponsored. Not passing through on a franchise rotation. That matters because we’re free to tell you when a HeatShield resurfacing is the right call and when it isn’t - when the terra cotta behind the tile is too far gone for CeCure to bond, when a slate flashing leak has been soaking the masonry so long that Resurfacer won’t hold. We stock genuine HeatShield TherMix, Resurfacer, and CeCure kits, plus stainless tee caps, top plates, and insulation blankets matched to HeatShield’s gauge spec. No builder-grade substitutes. No guessing.
Our Level 2 camera inspections end with photos you can see and a plain-English verdict. Background-checked, uniformed technicians. Most jobs in a single visit. The 90-Day Done Right Promise in writing - if it’s not right, we make it right, no paperwork, no arguing. A clean flue does not need a sales pitch.
Common HeatShield Chimney Cleaning Problems We Solve in Bangor
- TherMix™ cracking and delamination from Blue Mountain downdraft. Bangor’s position in the Kittatinny Ridge foothills means cold air funnels down tall exposed flues all winter. That freeze-thaw cycling spalls restored TherMix surfaces from the outside while the firebox heats them from within. We catch this with camera inspection before the crack network reaches the liner wall.
- CeCure™ joint repair failure behind acid-softened terra cotta. Coal-era flues in Bangor rowhouses spent decades condensing sulfur-laden moisture. The terra cotta behind a visible joint crack is often chalky and porous. We probe the substrate before applying CeCure - if the tile body is compromised, we tell you straight rather than patching over rot.
- Resurfacer™ pulling away from water-soaked masonry. Here’s where Bangor’s slate roofs enter the story. Improper step-flashing repairs at the slate-to-chimney junction - done by roofers who treated slate like asphalt - channel water into the masonry crown and wash behind the facing brick. Resurfacer needs sound, dry substrate. We reflash the slate properly, let the masonry dry, then resurface.
- Stainless liner insulation wrap compressing or tearing during careless sweeping. Unlined Bangor flues pool creosote-laden condensate at the tee. If a previous sweep tore the insulation blanket getting past the shoulder, that steel runs hot-cold-hot and rusts through at the pool point. We inspect the wrap integrity every time we clean.
- Coal-era creosote accumulation in smoke chambers. The previous owner of a Bangor rowhouse often left decades of hardened coal tar in the smoke chamber above the damper. Standard sweeping misses it. We remove it. Half a bushel is not unusual.
HeatShield Service in Bangor: What Local Conditions Mean for Your Equipment
Bangor’s original slate roofs are the hidden variable in HeatShield work here - step flashing at the slate-to-chimney junction was often redone by roofers who didn’t understand slate, so water tracks down the masonry and softens the terra cotta right where a HeatShield resurfacing is supposed to bond. In Easton or Stroudsburg you don’t see this slate-flashing failure pattern at anywhere near the same density.
On a call in the quarry-worker rowhouses along Market Street, our tech pulled a HeatShield TherMix-lined flue and found the top three feet of the restoration had spalled off where an old slate step-flashing repair was funneling meltwater into the masonry. We re-flashed the slate-to-chimney junction, re-coated the crown, and re-applied TherMix to the exposed section rather than quoting the homeowner a full stainless reline they didn’t need. The sweep also took a half-bushel of coal-era creosote out of the smoke chamber that the previous owner had never touched.
That is the difference between a sweep who knows Bangor and one who knows the manual. We do both. Bangor service area details are here if you want to see our full coverage map.
HeatShield Models & Products We Service in Bangor
We service the full HeatShield product line with genuine OEM-compatible materials, not aftermarket substitutes that mismatch gauge or insulation rating:
- HeatShield TherMix™ - cast-in-place insulating liner restoration for structurally sound flues needing thermal protection

Our trucks carry TherMix base and catalyst, Resurfacer compound, CeCure sleeve stock, and matched stainless fittings. For Bangor jobs, that means no waiting on a parts run to Allentown. HeatShield sales & service background is available if you want the full technical picture.

FAQs - HeatShield Chimney Cleaning in Bangor
Yes, if the flue is structurally sound and the coal-era creosote is fully removed first. TherMix needs clean, intact tile to bond to. In Bangor, we often find the smoke chamber packed with hardened coal tar that standard sweeping misses - we remove it before application. Call (610) 609-7634 and we’ll camera the flue to confirm suitability.
Most often it’s water intrusion from improper slate flashing at the chimney crown, not the Resurfacer itself. Bangor’s freeze-thaw cycle then spalls the restoration from behind. We inspect the flashing before we resurface - fixing the water source is part of the job. Call (610) 609-7634 for a camera inspection.
Yes. We are an independent HeatShield service provider - not manufacturer-authorized - which means we work on any HeatShield installation regardless of who did it. We assess what’s there, document it with photos, and recommend honest next steps. Call (610) 609-7634 to schedule.
The camera reveals cracked tile behind visible joints, creosote glazing in offsets that brushes skip, and water staining at the slate-to-masonry junction that indicates flashing failure. In Bangor’s century-old flues, these findings are routine. A basic sweep cleans; a Level 2 tells you if cleaning is enough. Call (610) 609-7634 to book.
We pay special attention to the crown and the slate flashing interface. Bangor’s hard freeze-thaw cycling and Blue Mountain wind exposure mean water entry at the top destroys liner work from above. Chimney Repair - Bangor work we do includes crown seal rated for Pennsylvania temperature swings and reflash slate-to-chimney junctions with proper step flashing, not the caulk-and-pray repairs we commonly find. Call (610) 609-7634 for specifics on your chimney.
