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 Cherry Hill, NJ
Creosote removal is the targeted cleaning process that strips hardened, flammable tar deposits from the flue liner and smoke chamber of your fireplace or wood-burning stove. In Cherry Hill, where older Colonial and split-level homes were built with masonry chimneys sized for different burning habits than most homeowners practice today, heavy creosote buildup is one of the most common problems we find during our Level 1 Inspection. Left alone, it is the leading cause of chimney fires in South Jersey – and a chimney fire does not always announce itself with drama. Many burn quietly inside the flue and go unnoticed until the liner is cracked and compromised.
At Hearthstone Chimney Co., we have been removing creosote from Cherry Hill chimneys since 1984, and Russell Haines has built the company around one standard: do it correctly, document it, and stand behind it. If you suspect heavy buildup or a strong tarry odor is coming from your fireplace, our Fireplace Cleaning experts are ready to help-call us at (856) 543-2929. A live person answers around the clock, every day. No voicemail, no callback queue.
Our creosote removal work sits within the broader family of services on our Chimney Cleaning & Sweep in Cherry Hill page, but heavy or third-degree creosote is a specialized job that goes well beyond a standard annual sweep – and it deserves its own plain-English explanation.
Understanding Creosote: Three Stages, One Danger
Not all creosote is the same. The National Fire Protection Association (NFPA 211) recognizes three distinct degrees, and the stage your chimney is at determines how we approach removal.
- First-degree creosote is the flaky, ashy residue that a standard chimney brush handles during a routine sweep. It forms when flue temperatures are adequate and the wood is well-seasoned. This is the easy one.
- Second-degree creosote looks like hard, crunchy black flakes or shiny tar deposits – sometimes both at once. It forms when smoldering fires or unseasoned wood drop the flue temperature low enough for heavier compounds to condense on the liner wall. A standard brush will not remove it. We use specialized rotary tools and chemical treatments to break it down safely.
- Third-degree creosote is a thick, concentrated glaze that has essentially baked onto the liner surface. It is difficult to remove and extremely flammable – ignition temperatures can be lower than the deposits you burned to create it in the first place. Removal at this stage sometimes requires chemical poultice application over multiple visits, and in some cases the liner itself needs to be relined rather than cleaned. Russell Haines will tell you plainly which situation you are in before any work begins.
Cherry Hill’s climate plays a role here. South Jersey winters are cold enough that homeowners burn wood for weeks at a stretch, but mild enough that fires often get started slowly or smoldered overnight to stretch the warmth. That temperature pattern – cooler-running fires, variable outdoor temps, humid air off the Delaware Valley – is exactly the combination that accelerates second-degree buildup. We see it constantly in homes across Erlton, Woodcrest, and the Barclay Farm neighborhood.
When You Need Creosote Removal
- A strong tarry or smoky smell coming from the fireplace, even when it’s not in use. In Cherry Hill’s humid summer months, creosote deposits off-gas into the living space. If the smell intensifies when the air conditioning runs, the negative pressure in the house is pulling odors down the flue. That is a sign of significant buildup, not just a dirty chimney.
- A dark, oily staining on the damper or smoke shelf. When technicians find a damper coated in dark, sticky residue during a Level-2 inspection, it typically means second- or third-degree creosote has been forming above the smoke shelf for at least one or two full burning seasons.
- You’ve had a chimney fire – or suspect you have. A chimney fire can sound like a low rumble or roaring in the walls, or it can go completely silent. After any suspected chimney fire, the flue must be inspected and all remaining creosote removed before the fireplace is used again. This is not optional. New Jersey fire code and your homeowner’s insurance both expect it.
- It’s been more than two years since your last professional sweep. NFPA 211 recommends annual inspection and cleaning for chimneys in regular use. Two or more burning seasons without service, especially in an older Cherry Hill home with a clay tile liner, means creosote accumulation is almost certain to be beyond what a standard brush can address.
- You burn mostly softwoods or unseasoned firewood. Pine, cedar, and wet hardwoods produce far more creosote than dry, seasoned oak or hickory. If you’ve been burning whatever was on sale at a local supply yard without checking moisture content, second-degree buildup is very likely.
- Your camera inspection shows heavy dark deposits inside the flue. Our Level-2 inspections use a camera that travels the full length of the liner. When we see significant dark coating on the tile or stainless, we photograph it, show it to you on screen, and give you a plain-English verdict on what stage you’re dealing with and what removal will take.
Our Creosote Removal Process
- Pre-job Level-2 camera inspection. Before a brush or tool touches the flue, we run a camera down the full length of the liner. This is not a formality. It tells us exactly which degree of creosote we are dealing with, whether the liner is cracked or damaged, and what the safest approach is. You see every photo. You get a plain-English verdict on what we found before we quote the job. This step is what separates a documented, accountable cleaning from a guess.
- Full drop-cloth and containment setup. We protect your floors, hearth, and nearby furniture before anything else is opened up. Creosote dust is oily and dark, and a careless setup can leave a mess that is harder to remove than the creosote itself. Our uniformed technicians treat your home like it belongs to them.
- Mechanical removal – rotary tools and brushes. For first- and most second-degree deposits, we use professional-grade rotary cleaning systems to break up and remove buildup from the full length of the liner. Standard chimney brushes are sized for first-degree sweeps. Third-degree glazed deposits require heavier equipment and, in severe cases, chemical treatments.
- Chemical treatment where indicated. When second-degree creosote has hardened into a brittle crust, or when third-degree glazing is present, we apply a professional-grade chemical creosote modifier. The chemistry alters the structure of the glaze, making it porous and brittle enough to be mechanically removed – either immediately or on a scheduled follow-up visit, depending on severity. We use products sourced through Copperfield and Olympia Chimney supply channels, not hardware-store sprays.
- Smoke chamber and smoke shelf cleaning. The smoke shelf above your damper is where a surprising amount of creosote concentrates. Many crews clean the flue and ignore the smoke chamber – we don’t. That shelf is where the earliest deposits settle, and skipping it means buildup starts again faster after the job.
- Post-job camera verification and written documentation. After cleaning, the camera goes back in. We verify the liner is clear, photograph the results, and note any structural concerns – liner cracks, damaged joints, mortar deterioration – in a written report you can keep. That report is what makes the 90-Day Done Right Promise meaningful: you have documentation of what was done and what we found, in writing, with no arguing.
Creosote Removal Pricing in Cherry Hill
Creosote removal in Cherry Hill typically costs between $200 and $800, depending on the degree of buildup, the number of flue sections affected, and whether chemical treatment is needed in addition to mechanical cleaning. The ranges below reflect what we see in actual jobs across the area.
| Service | Typical Range |
|---|---|
| First-degree creosote removal (standard sweep) | $150 – $250 |
| Second-degree creosote removal (rotary tools) | $250 – $450 |
| Third-degree glaze removal (chemical + mechanical, single visit) | $450 – $800 |
| Third-degree glaze treatment (multi-visit, severe cases) | $700 – $1,200+ |
| Level-2 camera inspection (included with removal) | Included |
Several factors shift the final number: flue height (two-story chimneys in Woodcrest or Cherry Hill Estates take longer to service than single-story flues), liner material (clay tile holds deposits differently than stainless), and whether the smoke chamber needs separate treatment. A fireplace that hasn’t had Chimney Cleaning & Sweep services in five years is a different job than one that had a routine sweep eighteen months ago.
When a Level 2 Inspection is needed, a square deal means the number on the estimate is the number on the invoice. We give you upfront pricing before any work begins, and if we find something unexpected during the camera inspection, we tell you before we proceed. No surprises.
We also offer $50 Off Any Repair Over $250, and a permanent 5% discount for seniors and veterans. If you have a written estimate from another company, we’ll give you a free second opinion – no charge, no pressure.

A Safety Note on Creosote and Chimney Fires
Creosote removal is not a DIY project – and we say that plainly, not to sell you a service call. Third-degree creosote glaze reaches ignition temperatures that can crack clay tile liners and breach the fireplace structure. Chemical creosote modifiers are designed for professional application in a vented, controlled environment. Incorrect use can accelerate a hazard rather than reduce it. If you smell strong tar odor, see an unusual dark coating on your damper, or have any reason to believe a chimney fire has occurred, stop using the fireplace and call a certified professional. The risk is fire damage to the house, not just a dirty flue.
FAQs – Creosote Removal in Cherry Hill, NJ
How often does creosote need to be removed from a Cherry Hill fireplace?
Creosote should be professionally assessed every year – NFPA 211 is clear on annual inspection for any fireplace in regular use. Whether removal is needed at that point depends on what the inspection finds. In Cherry Hill specifically, homeowners who burn three or more cords of wood per season through a cold winter often develop second-degree buildup in a single season if the wood wasn’t fully seasoned. If you burn less frequently or use a fireplace insert, annual inspection still applies, but heavy removal may only be needed every two to three years. Call (856) 543-2929 and we’ll tell you exactly where you stand after the camera inspection.
Can creosote removal be done the same day as the inspection?
Yes, in most cases. First- and second-degree creosote removal is completed during the same visit as the inspection – our technicians arrive with the tools and materials to handle both. Third-degree glazing sometimes requires a chemical treatment to sit and work before mechanical removal, which may mean a follow-up visit. We’ll tell you during the inspection which situation applies before any work begins, so you can plan accordingly.
What is the difference between a standard chimney sweep and creosote removal?
A standard chimney sweep removes first-degree creosote – the light, flaky ash and soot that accumulates in a properly used fireplace. Creosote removal, as a specific service, targets second- and third-degree buildup: hardened, glazed deposits that require rotary mechanical tools, chemical treatments, or both. If you call for a sweep and the technician finds second-degree buildup, a brush won’t fully address it. Our Level-2 camera inspection tells us before we start which service your chimney actually needs. The parent service page for Chimney Cleaning & Sweep in Cherry Hill covers the full range of what routine cleaning includes.
Is creosote removal covered by homeowner’s insurance in New Jersey?
Routine creosote removal is considered maintenance and is not typically covered by homeowner’s insurance. However, if a documented chimney fire caused damage to the liner or firebox, the repair portion of the work – relining, for example – may be covered depending on your policy. We provide written documentation of every inspection and every job completed, including photographs, which gives you the clearest possible record if you need to file a claim for fire-related damage. For specifics, you’d need to check with your insurer, but we can provide whatever documentation they require.
Key Takeaways
- Creosote forms in three degrees, and only first-degree deposits are removed by a standard brush sweep.
- Cherry Hill’s climate and burning patterns – particularly smoldering fires in cold stretches – accelerate second-degree buildup in masonry chimneys.
- A Level-2 camera inspection comes before and after every removal job at Hearthstone, so you see documented proof of what was done.
- Pricing ranges from $150 for a standard first-degree sweep to $800 or more for severe third-degree glazing treatment.
- All work is covered by the 90-Day Done Right Promise – in writing, no arguing.
- Never attempt to remove second- or third-degree creosote without professional equipment. The fire risk is real and serious.
