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.

AfterCreosote Removal in Bangor, PA
Creosote removal is the process of stripping the hardened, tar-like residue that builds up inside your flue every time you burn wood – and in Bangor, it’s one of the most common reasons we’re called out to a chimney that hasn’t been serviced in a few years. Left alone, creosote narrows the flue, blocks proper draft, and – at stage three – becomes a fuel source for a chimney fire that burns at over 2,000 degrees Fahrenheit. Most homeowners who need this service don’t know they need it until they notice a sharp, acrid smell from the fireplace or see smoke backing into the room on a cold morning, which is why regular Chimney Cleaning & Sweep services matter.
Hearthstone Chimney Co. has been handling creosote removal in Bangor and across the Slate Belt since 1984 – over 42 years of working on everything from the older stone-and-mortar chimneys in the Chestnut Hill neighborhood to the prefab fireplace inserts in newer builds along Boro Road. Our work is covered by the 90-Day Done Right Promise, in writing, no arguing. Call us at (610) 609-7634 – a live person answers every time, day or night – or read on to understand exactly what creosote removal involves and what it costs in this market.
This page sits under our full Chimney Cleaning & Sweep in Bangor service, which covers routine annual sweeps alongside the heavier-duty work described here.
What Creosote Is and Why Stage Matters
Not all creosote is the same, and the difference between a routine cleaning and a full creosote removal job comes down to what stage of buildup you’re dealing with. This distinction matters because it determines the tools we use, the time on site, and honestly – the price.
Stage 1 is dry, flaky soot. A standard chimney brush clears it in one pass. If you’re burning seasoned hardwood and getting your Fireplace Cleaning done every year, this is usually the worst you’ll see.
Stage 2 is the shiny, tar-like deposit that forms when wood burns at lower temperatures – common in Bangor homes where the fireplace is used on a low smolder to stretch out the evening heat. It’s harder, sticky, and requires rotary tools or a chemical loosening agent before brushing.
Stage 3 is the one that gets people in real trouble. It’s thick, glazed creosote – almost like poured plastic coating the inside of the flue. It doesn’t respond to brushing alone. We use a professional-grade chemical application, often with a HeatShield-compatible process where lining repair is also needed, followed by mechanical removal and a full camera inspection to confirm the flue is clean to the tile or liner surface.
In Bangor’s climate – cold winters that arrive early and linger well into March – the combination of older, sometimes undersized flues and wet or mixed-wood burning habits pushes a meaningful number of local chimneys into Stage 2 or Stage 3 faster than homeowners expect. We see it regularly in the older Victorians along Chestnut Street and in the ranch-style homes off Pennsylvania Avenue where the insert was added in the 1990s and hasn’t had a proper sweep since.
When You Need Creosote Removal
A standard annual sweep is preventive. Creosote removal is corrective – it’s the right call when one or more of these situations applies to your chimney:
- A smoky or sharp smell coming from the firebox, even when no fire is burning. This is often Stage 2 or Stage 3 creosote off-gassing, especially noticeable during humid summers in the Slate Belt or on warm autumn days when the flue heats up from direct sun.
- Smoke backing into the room rather than drafting up the flue. Heavy creosote buildup restricts the flue opening and kills draft. If your fire smokes sideways within the first five minutes of lighting, restricted airflow from buildup is a leading cause.
- A visible dark, shiny crust on the flue walls. If you look up the firebox with a flashlight and see a glazed or lumpy coating rather than clean clay tile or metal liner, you’re looking at Stage 2 or Stage 3 material.
- You haven’t had the chimney swept in three or more years and burn regularly. Bangor winters run long. A household burning four to five cords a season can accumulate a quarter inch of Stage 2 creosote in less than two burning seasons, particularly with shorter, cooler fires.
- After a suspected or confirmed chimney fire. A chimney fire – even a brief, fast one you may not have noticed – superheats creosote and can fuse it to the flue wall in a way that requires aggressive removal plus a Level-2 camera inspection to document any liner cracking before the fireplace is used again. This is a safety matter, not just a cleaning one.
- A new home purchase, especially a home built before 1990. Bangor has a significant stock of pre-war and mid-century homes. Sellers don’t always disclose chimney condition accurately. We regularly find Stage 2 and Stage 3 buildup in homes that were listed as “chimney cleaned” – and our camera inspection gives you a documented record of what we found before we started.
Our Creosote Removal Process
We don’t cut steps. Every creosote removal job follows the same documented sequence, whether we’re working in a small Cape Cod off Water Street or a larger colonial on the edge of town.
- Pre-job inspection and documentation. Before we touch the chimney, Russell or one of our background-checked, uniformed technicians runs a Level-2 camera inspection from firebox to crown. You see the photos on a screen at the job site. We give you a plain-English verbal summary of what we found – stage of creosote, any liner damage, any cracking – so you know exactly what we’re dealing with before work starts. No surprises later.
- Drop cloths and full containment setup. We protect your floors, hearth, and furniture before anything else. Creosote removal is messier than a standard sweep, and we treat your home accordingly.
- Chemical treatment where Stage 2 or Stage 3 buildup is present. For shiny or glazed creosote that won’t respond to brushing, we apply a professional-grade chemical loosening agent that converts hardened deposits into a drier, removable material. This step requires dwell time – we don’t rush it – and it’s what separates a real removal from a cosmetic sweep.
- Mechanical removal with rotary brushes and professional vacuum system. Once the chemical treatment has done its work, we use rotary brush systems sized to your specific flue diameter to scrub every inch of the liner surface. Our vacuum equipment is HEPA-rated so particulate stays contained and doesn’t migrate into your living space.
- Post-removal camera inspection. We run the camera a second time after the removal to confirm the flue is clean to the liner surface. If we find areas that need a second pass, we do it on the same visit. That’s what the 90-Day Done Right Promise means in practice – the job is done when it’s done right, not when the clock runs out.
- Written verdict and recommendations. You get a plain-English summary of what we found, what we did, and any follow-up your chimney may need – liner repair, a new cap, a crown coat, or nothing at all. If repairs are warranted, we quote them on the spot with upfront pricing. The number on the estimate is the number on the invoice, period.
Creosote Removal Pricing in Bangor
Creosote removal in Bangor typically costs more than a standard annual sweep because it involves specialized tools, chemical agents, and longer time on site. The exact cost depends on the stage of buildup, the height and condition of your flue, and whether liner repair is needed afterward. Here are honest ranges based on what we see in this market:
| Service | Typical Range (Bangor Market) |
|---|---|
| Stage 1 creosote – standard sweep included | $149 – $219 |
| Stage 2 creosote removal (rotary brush, single flue) | $249 – $399 |
| Stage 3 glazed creosote removal (chemical treatment + mechanical, single flue) | $399 – $699 |
| Level-2 camera inspection (included with removal jobs) | Included |
| Liner repair after removal (HeatShield or Olympia Chimney liner, if needed) | Quoted separately on site |
A few things that move the number up or down: chimney height matters – a two-story flue takes longer to brush than a single-story run. Flue condition matters too. If the liner is cracked or deteriorating underneath the creosote, we’ll find it on the camera inspection and give you a repair quote before we do any additional work. And if your job qualifies as a repair over $250, our standing $50 Off Any Repair Over $250 offer applies automatically – no coupon needed, no asking for it.
We also offer a permanent 5% Senior and Veteran discount, which covers a significant portion of our Bangor customers. And if another company has given you a written estimate, bring it to us – we’ll give you a free second opinion before you spend a dollar.
Call (610) 609-7634 to get an exact quote. Estimates are free, and the number we give you before the job starts is the number on the invoice when we’re done.
Why Hearthstone for Creosote Removal in Bangor
There’s no shortage of chimney companies willing to take your money for a sweep and call it a day. The difference with Hearthstone is documentation and accountability. When we do a creosote removal, you get before-and-after camera photos you can actually see – not a verbal assurance that the flue is clean. That documentation matters if you’re buying or selling a home, if your insurance company asks questions after a chimney fire, or simply if you want to know you got what you paid for.
Russell Haines has run Hearthstone Chimney Co. since its founding in 1984. The company was built around the idea that a homeowner who trusts you with their chimney should be able to trust the verdict they get. That’s why we started documenting every inspection with photos before it was standard practice, and it’s why the 90-Day Done Right Promise exists as a written commitment rather than a verbal one. If something we did isn’t right within 90 days, we come back and make it right. No paperwork, no arguing.
We use professional-grade materials where materials are part of the job – liners from Olympia Chimney, relining systems from Gelco where appropriate – because builder-grade substitutes fail faster and cost the homeowner more in the long run. We don’t cut that corner. Our technicians are background-checked, arrive in uniform, and complete most jobs in a single visit, so you’re not coordinating three callbacks to get one job finished.
Bangor is a smaller market, which means our reputation here is built one chimney at a time. We’ve been doing this for over 42 years because the work holds up. That’s the only reason we’re still here, and it’s the only reason we intend to be here in thirty more years.

FAQs – Creosote Removal in Bangor, PA
How much does creosote removal cost in Bangor, PA?
Creosote removal in Bangor typically runs $249 to $699 for a single flue, depending on the stage of buildup. Stage 2 shiny creosote – the most common type we find in homes that burn on a low smolder through Bangor’s long winters – generally falls in the $249 to $399 range. Stage 3 glazed creosote, which requires a chemical treatment before mechanical removal, runs $399 to $699. Both include a Level 2 Inspection with before-and-after photos. Call (610) 609-7634 for an exact quote – estimates are free and the number we give you before we start is the number on your invoice.
Is creosote removal different from a regular chimney sweep?
Yes – a standard chimney sweep clears Stage 1 dry soot and light debris using brushes, and it’s the right call for a chimney that’s swept annually with good burning habits. Creosote removal addresses Stage 2 and Stage 3 buildup, which require rotary mechanical tools and, for glazed deposits, a chemical loosening agent applied before brushing. It takes longer, uses different equipment, and costs more than a routine sweep – for good reason. If you’re not sure which you need, call us and we’ll assess on the first visit with the camera before we quote anything.
Can I remove creosote myself?
Hardware stores sell creosote removal sprays for use during a fire, and these can help convert light Stage 1 deposits into an easier-to-brush material. They are not a substitute for professional Stage 2 or Stage 3 removal. Glazed creosote requires mechanical rotary tools calibrated to your specific flue diameter, and working inside a flue without proper containment equipment releases fine particulate that is a health hazard. More importantly, you won’t be able to assess whether a liner is cracked underneath the buildup without a camera inspection – and burning on a cracked liner is a structural fire risk. For anything beyond very light surface soot, professional removal is the right call.
How do I know if my Bangor chimney has dangerous creosote buildup?
The clearest signs are smoke backing into the room when a fire is lit, a sharp acrid smell from the firebox on warm days, or a visible shiny or lumpy coating on the flue walls when you look up with a flashlight. In Bangor specifically, we see heavy buildup most often in homes with older, undersized flues – common in the pre-war and mid-century housing stock – and in homes where the fireplace is used on a low, smoldering burn rather than a hot fire with seasoned hardwood. If you haven’t had the chimney swept in three or more years and you burn regularly, a Level 1 Inspection or camera inspection is the only way to know for certain. Call (610) 609-7634 and we’ll schedule a visit – the inspection is included when you book a removal job.
