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 Joliet, IL
Creosote removal in Joliet typically costs between $250 and $650, depending on how heavily the deposit has built up and which class of creosote the camera finds in your flue. Most jobs are completed in a single visit, and every one starts with a written price before any work begins.
If you burn wood in Joliet – whether that’s a fireplace in Shorewood, a wood stove off Black Road, or an older insert in the Highlands neighborhood – creosote is the inevitable byproduct. It forms every time combustion gases cool against the flue liner and solidify into a carbon-based deposit. Left alone, it narrows airflow, traps heat, and at Class III it becomes a fuel source for a chimney fire that burns at over 2,000 degrees Fahrenheit. That’s not a figure we use for effect. It’s what the NFPA 211 standard is built around, and it’s why Level Two Chimney Joliet treats creosote classification as the first step, not an afterthought - and why we offer Level 1 Inspection as the starting point for every system.
Our Chimney Cleaning & Sweep in Joliet service covers the full spectrum of flue maintenance, and creosote removal sits at the center of it. When a Level Two technician arrives, they’re not doing a flashlight inspection and calling it done. A camera goes down the flue first. What it finds determines exactly what we quote you – in writing, before anyone picks up a tool.

When You Need Creosote Removal
Creosote doesn’t announce itself the way a cracked crown or a displaced cap does. It builds quietly, and by the time most homeowners notice something, the deposit is already restricting the flue. Here are the situations where a Chimney Cleaning & Sweep services appointment in Joliet is warranted:
- Your fireplace or wood stove smells like campfire or asphalt when it’s not in use. A strong odor at rest – especially in Joliet’s humid summers – is one of the most consistent signs of a heavy creosote deposit reacting with moisture inside the flue.
- You’ve gone two or more heating seasons without a professional cleaning. NFPA 211 calls for inspection and cleaning at least once annually. Two winters of regular burning in Joliet’s colder months can produce Class II deposits even with dry, seasoned wood.
- You burn frequently or use unseasoned (green) wood. Cooler, smoldering fires – exactly what unseasoned wood produces – accelerate creosote formation. We see this pattern regularly in older neighborhoods near the Des Plaines River corridor where houses were built around wood-burning systems and retrofitted inserts were added later.
- Your damper shows black, flaky, or shiny residue when you look up into the firebox. Flaky residue is typically Class I. Shiny, tar-like buildup that doesn’t brush away easily is Class III – glazed creosote – and it requires chemical treatment before mechanical removal is safe or effective.
- You’ve recently had a chimney fire. Even a small chimney fire changes the texture and adhesion of remaining deposits. A camera scan after any suspected chimney fire is required by NFPA 211, and creosote removal of whatever remains is the follow-up step before you use the fireplace again.
- Your home inspection report flagged creosote buildup. Buyers in Joliet increasingly receive Level 2 inspection reports as part of their real estate transaction. If yours flagged creosote accumulation, that’s the documentation you need to bring to us – we’ll quote removal from the written findings.
Our Creosote Removal Process
We work in a documented sequence. The order matters because it protects your home and it protects the accuracy of the written price you receive before work starts. Here’s what a creosote removal appointment at Level Two Chimney Joliet looks like from arrival to sign-off:
- Camera scan and creosote classification. The technician runs a CCTV camera down the flue from the firebox to the crown. The footage is recorded and becomes part of your documented photo record. What the camera shows determines the class of creosote: Class I (light, dusty, brushable), Class II (crunchy, tar-like, harder to remove), or Class III (glazed, hardened, sometimes called third-degree creosote). Classification drives everything – the method, the time, and the price.
- Written price delivered before work begins. Under Clause 1 of the Haven Standard – the “Have it in writing” provision – you receive a written scope, a written price, and a written warranty before any cleaning starts. If the camera finds Class III deposits requiring chemical treatment, that’s on the quote. There are no additions after the fact.
- Prep and containment. The firebox opening is sealed with a dust barrier, and drop cloths protect the hearth and surrounding floor. Joliet’s older homes – particularly the brick and frame construction common in the Cathedral area and around Ingalls Park – often have open fireplace surrounds that need careful protection. We treat every room like we’re working in our own house.
- Mechanical removal. For Class I and most Class II deposits, rotary brush systems – using Copperfield professional-grade equipment – clear the flue liner from top to bottom. Debris falls into a sealed firebox collection system. The smoke chamber, smoke shelf, and damper area are hand-cleaned separately, because those surfaces accumulate deposits that brushes miss.
- Chemical treatment where required. Class III glazed creosote doesn’t respond to mechanical brushing alone. A chemical conversion agent is applied to break the bond between the deposit and the flue liner wall. We allow adequate dwell time, then return to mechanical removal. HeatShield products are used where liner repair or sealing is needed in the same visit.
- Post-removal camera confirmation and documentation. The camera goes back down the flue when removal is complete. The before-and-after footage is saved and delivered to you as part of the documented photo record – Haven Standard Clause 4. You leave with proof of what was there and proof that it’s gone, not just our word for it.
A note on Class III creosote and safety: Glazed creosote removal involves chemical agents applied inside a confined flue, and it requires proper ventilation and protective equipment. This is not a DIY process. The risk isn’t just incomplete removal – attempting to brush hardened Class III deposits without chemical pre-treatment can dislodge chunks that block the flue or damage an already-stressed liner. If you’ve seen anything shiny and tar-like inside your firebox, call a trained professional for Level 2 Inspection before lighting another fire.

AfterCreosote Removal Pricing in Joliet
Creosote removal in Joliet runs between $250 and $650 for most residential jobs. The camera tells us which end of that range applies before we quote it. Here’s how the numbers break down:
| Creosote Class | Typical Joliet Price Range | Notes |
|---|---|---|
| Class I (light, dusty) | $250 – $325 | Brushable; included in standard sweep scope for most systems |
| Class II (crunchy, tar-like) | $325 – $475 | Heavier mechanical work; smoke chamber often requires separate attention |
| Class III (glazed, hardened) | $475 – $650+ | Chemical treatment required before mechanical removal; multi-step process |
A few things affect where your job lands within those ranges:
- Flue length and configuration. Taller chimneys – common on Joliet’s two-story Victorian-era and early 20th-century homes – mean more liner to clean and more time on the roof.
- System type. A freestanding wood stove with a long horizontal run to the flue collar accumulates deposits differently than a straight masonry fireplace. Offsets and elbows trap creosote in ways that add time.
- Liner condition. If the camera finds cracking or spalling alongside the creosote, we’ll include liner repair options (using DuraFlex or HeatShield materials where applicable) in the same written quote so you can decide before work starts.
- Time since last cleaning. A system that hasn’t been touched in five or six years will often have layered deposits – Class I on top of Class II underneath – that take longer to address.
There is no “call for a quote” here. You get the number in writing after the camera is back up. Call (815) 620-5234 to schedule the scan and get your written price – the estimate is free, and the price doesn’t change once it’s written.
If you have a written estimate from another company, bring it. We offer a Free Second Opinion on any written estimate from a competitor, with no obligation.
FAQs – Creosote Removal
How often does creosote need to be removed in Joliet?
NFPA 211 requires inspection and cleaning at least once per year for any wood-burning system in active use. In Joliet, where heating seasons typically run from October through March, homeowners who burn two to three fires per week will accumulate meaningful deposits by spring – sometimes Class II – even with properly seasoned wood. If you burn less frequently, annually is still the right interval because moisture and animal debris can mix with light deposits and create a different kind of blockage. Call (815) 620-5234 to get on the schedule before the fall backlog fills up.
What is the difference between Class I, Class II, and Class III creosote?
Class I creosote is the dusty, flaky gray-to-black soot that brushes away easily – the kind a standard Fireplace Cleaning removes. Class II is a harder, crunchy, tar-like deposit that takes longer to remove and often coats the smoke shelf and smoke chamber. Class III is glazed creosote: a shiny, hardened layer that has been through high heat and bonded tightly to the flue liner wall. It won’t brush off without chemical pre-treatment, and it’s the type most associated with chimney fires. Our camera identifies the class on every visit, so there’s no guesswork about what removal will cost or require.
Is creosote removal something I can do myself?
Class I deposits can be partially addressed with consumer-grade chimney brushes, and there are creosote-reducing logs sold at home improvement stores. What those products don’t do is document the condition of your liner, identify Class II or Class III deposits that require different treatment, or give you any kind of written warranty on the result. For Class II and especially Class III, mechanical removal without chemical pre-treatment can crack a stressed liner or compact hardened chunks into a blockage. For anything beyond the lightest surface deposits, a trained technician with a camera and the right equipment is the safer call – and the documented record you get is something a chimney brush kit never provides.
What happens if creosote isn’t removed?
Uncleaned creosote restricts airflow, which means smoke and carbon monoxide are more likely to draft back into your living space. At Class III, the deposit itself becomes a fuel source inside your chimney – chimney fires burn at temperatures that crack clay tile liners, warp stainless steel, and compromise the mortar joints holding your chimney together. Repair costs after a chimney fire in Joliet typically start around $1,500 for liner work and can reach several thousand dollars for full rebuilds. The removal appointment is substantially less expensive than the repair appointment. We’ve seen both outcomes, and the math isn’t complicated.
Why Joliet Homeowners Choose Level Two Chimney Co.
We’ve completed more than 38,000 chimney inspections and cleanings since 2009, and every one of them started with a written price and ended with a documented photo record. That’s not a marketing line – it’s the operational baseline we set in the first year and have run continuously since. Clause 4 of the Haven Standard requires the photo record on every job. The written price requirement is Clause 1. Those practices were in place here before regulators or insurers started asking for them.
In Joliet specifically, we work across the city’s range of housing stock: mid-century brick ranches on the south side, late Victorian frame homes near the cathedral district, newer construction in Prestbury and the Woodgate neighborhoods, and everything in between. The chimney systems are different, the flue configurations are different, and the creosote patterns are different. A two-story 1920s home with an original clay tile flue and an added insert generates different deposits than a 2002 build with a factory-built fireplace and a listed liner. We note the difference because the price and the process follow the camera footage, not a flat-rate menu.
Every technician is background-checked and uniformed. You’ll get a text when they’re on the way and a name before they arrive – not a generic crew. The 365-Day Done Right Promise is stamped on every job: if it’s not right, we make it right. If you have a written estimate from another sweep company in Joliet, bring it in. We’ll give you a second opinion at no charge and let you compare the scope line by line.
