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 Severna Park, MD
Creosote removal is the process of clearing the hardened, flammable residue that wood-burning fireplaces and stoves deposit inside your flue over time. In Severna Park, where older homes on tree-lined streets from Olde Severna Park to Cape Arthur burn a lot of firewood through our cool, damp winters, that buildup happens faster than most homeowners expect. Left unaddressed, heavy creosote deposits are the leading cause of chimney fires – and a chimney fire in a house you’ve lived in for twenty years is a serious event, not a minor inconvenience.
At Hearthstone Chimney Co., we’ve been removing creosote from chimneys in Anne Arundel County since 1984 – over 42 years of work, documented with photos, backed in writing, and done right the first time. If you’re due for a Level 1 Inspection or you already know you’ve got buildup, call us at (443) 464-2560. A live person answers every call, around the clock.
This page is part of our broader Chimney Cleaning & Sweep in Severna Park service – if you want the full picture of what we do when we open up your flue, start there.
What Creosote Is and Why It Forms
When wood burns, it releases combustion byproducts – gases, water vapor, unburned carbon particles – that travel up the flue. As those hot gases meet the cooler masonry of your chimney, they condense on the flue walls. The residue that sticks is creosote.
It doesn’t always look the same. NFPA 211, the national fire safety standard that governs chimney maintenance, recognizes three distinct stages of creosote buildup, and each one behaves differently:
- Stage 1 (flaky, dusty deposits): The lightest form. Looks like soot. Standard chimney brushes handle it during a routine annual sweep. Most homeowners who burn two to three cords per season and keep their fires hot will see Stage 1 buildup.
- Stage 2 (tar-like, shiny, crunchy glaze): This is where the risk escalates. Stage 2 creosote has already begun to harden against the flue liner. It doesn’t brush away easily and often requires chemical treatments or specialized rotary tools. Severna Park homes with older, oversized flues – common in the split-levels and colonials built along the waterfront neighborhoods of the 1970s and early 1980s – tend to accumulate Stage 2 buildup when those large flues are fired by modern, more efficient inserts that run cooler exhaust.
- Stage 3 (glazed, dripping, or poured-in-place): The most dangerous form. It looks like tar that’s been baked onto the liner walls. Stage 3 creosote ignites at around 2,000 degrees Fahrenheit – hot enough to damage or crack your flue liner and compromise the structure of your chimney. Rotary cleaning systems and chemical glazed-creosote removers like those we source through Copperfield are typically required. In some cases, a full liner inspection is warranted before the chimney is used again.
Here’s the detail that matters for Severna Park specifically: our winters run damp. Humidity from the Severn River and the Chesapeake shoreline keeps ambient moisture high even on cold days. Wet wood – or wood stored outdoors without proper cover – burns at lower temperatures and produces far more creosote than properly seasoned hardwood. We see Stage 2 and Stage 3 buildup regularly in homes that burned anything other than well-seasoned oak, hickory, or cherry, regardless of how often the chimney was swept.
When You Need Creosote Removal
Some of these signs are easy to notice. Others you’ll only catch during an inspection. Either way, the list below covers the situations where creosote removal is overdue – not optional.
- It’s been more than a year since your last sweep. NFPA 211 and the Chimney Safety Institute of America both recommend annual inspections and cleanings for any chimney in active use. In Severna Park, where many homeowners burn wood from October through March, a full season is enough to create meaningful buildup.
- You smell a sharp, oily, or smoky odor in summer. When the fireplace isn’t in use and the flue is cold, creosote releases a heavy, acrid smell that travels backward into living spaces. During Severna Park’s humid summer months, that smell is often the first sign a homeowner notices – and it almost always means Stage 2 or beyond.
- Your fires smoke more than they used to. Airflow restriction from creosote buildup on the flue walls reduces draft. If you’re fighting smoke in the room more than you did two or three seasons ago, the flue is likely narrowed and needs clearing.
- You burn frequently or use unseasoned wood. Homeowners who burn four or more cords per season, or who have used wood with visible moisture or green tint, are high-probability Stage 2 candidates – even if the fireplace seems to be working normally.
- You’ve had a chimney fire. Even a small, fast-burning chimney fire can warp a liner, crack mortar joints, or leave behind Stage 3 deposits baked into crevices that normal brushes won’t reach. A thorough removal and Level-2 camera inspection are both warranted after any chimney fire, however brief.
- Your home is in Severna Park and was built before 1990. Older masonry chimneys in this area were often built with flue sizes that don’t match modern insert dimensions. That mismatch slows exhaust velocity and creates exactly the condensation conditions that accelerate creosote formation. If you’ve never had a proper Level-2 inspection with a camera, you may not know what’s inside.
Our Creosote Removal Process
We don’t show up with a brush and work blind. Every creosote removal job at Hearthstone Chimney Co. follows a documented process – one we’ve refined over more than four decades of work in homes across Severna Park and the surrounding communities.
- Pre-service inspection and camera assessment. Before we touch a brush, Russell Haines or one of our background-checked, uniformed technicians runs a Level-2 camera inspection through the flue. The camera image shows us the type and severity of creosote present, the condition of the liner, and whether any cracks or gaps need attention. You see the same photos on the spot, and we give you a plain-English verdict – not jargon, not an upsell pitch.
- Job-site protection. We lay drop cloths across the hearth surround and the surrounding floor. Your living area stays clean. Our technicians work in uniform and clean up after themselves. That’s a standard, not an exception.
- Stage-matched cleaning method. Stage 1 deposits get removed with professional-grade rotary brushes sized to your specific flue dimensions. Stage 2 buildup typically requires chemical application first – we use professional-grade chemical treatments sourced through suppliers like Copperfield and Olympia Chimney – followed by mechanical removal. Stage 3 glazed creosote requires rotary power systems and, in severe cases, may require multiple visits or a discussion about liner replacement before the fireplace is safe to use again. We tell you which situation you’re in before work begins, with upfront pricing – the number on the estimate is the number on the invoice.
- Full flue sweep and debris removal. Once chemical treatments have had time to work and mechanical tools have done their job, we brush the flue from top to bottom and collect the debris at the firebox. Everything comes out.
- Post-cleaning camera verification. We run the camera again after cleaning. This is how we confirm the work is done – not by feel, not by assumption. You see the before and after images side by side. That’s the documentation that makes our 90-Day Done Right Promise mean something.
- Written report and plain-English verdict. You receive a written summary of what we found, what we did, and whether any follow-up is recommended. If your liner has cracks that need repair, or your flue cap needs replacement, we tell you – with photos – and we give you an upfront price for the additional work. No hidden charges that appear on the invoice.
One note on safety: Stage 2 and Stage 3 creosote removal should only be done by trained professionals with the right tools and chemical agents. The process involves strong chemical agents, fine particulate debris, and in some cases, access to the roofline. This is not a DIY project. A mistake in a flue with significant buildup can dislodge material that further blocks the liner or creates an air quality hazard inside your home. We say this not to alarm you but because a real craftsman is always straight about where the danger is.
Creosote Removal Pricing in Severna Park
Creosote removal in Severna Park typically runs between $150 and $550, depending on the severity of the buildup and the method required. Here’s how the pricing generally breaks down:
| Service | Typical Range | Notes |
|---|---|---|
| Stage 1 removal (routine sweep) | $150 – $250 | Included in standard annual cleaning; brush-only method |
| Stage 2 removal (chemical + mechanical) | $275 – $425 | Chemical treatment applied, mechanical tools required; single visit in most cases |
| Stage 3 removal (glazed creosote) | $400 – $550+ | Rotary power system required; may require two visits depending on severity |
| Level-2 camera inspection | Included with removal service | Pre- and post-cleaning; photos provided |
Several factors affect where your job lands in those ranges: the height and diameter of your flue, the presence of any bends or offsets (common in older Severna Park colonials that had chimneys retrofitted), and the extent of the buildup found during the initial camera pass.
If you’ve already received a written estimate from another company, we offer a free second opinion. No pressure, no sales pitch – just a straight read on what the job actually requires and what it should cost. Call (443) 464-2560 and a live person will set up the visit.
We also offer $50 off any repair over $250, and a permanent 5% discount for seniors and veterans – two groups that make up a significant portion of the longtime Severna Park homeowners we serve.
FAQs – Creosote Removal
How often does creosote need to be removed from a chimney in Severna Park?
Creosote should be inspected and removed with Chimney Cleaning & Sweep services at least once per year if you use your fireplace regularly – more often if you burn frequently or have burned unseasoned wood. In Severna Park, where humid winters from the Chesapeake region encourage lower-temperature burns and faster buildup, annual cleaning is the minimum. Homeowners who burn three or more cords per season often benefit from a mid-season check as well. Call (443) 464-2560 and we’ll help you figure out the right schedule for how you actually use your fireplace.
Is Stage 3 creosote dangerous to remove on my own?
Stage 3 creosote is not safe to remove without professional equipment and training. The glazed material can shatter under brushing and send debris through flue cracks into wall cavities, or create fine particulate that travels through the home. The chemical agents used to break down glazed deposits are strong and require proper handling and ventilation. Beyond the physical hazards, a chimney with Stage 3 buildup often has underlying liner damage that needs to be assessed before the fireplace can be used again. This is one of the situations where calling a professional isn’t just the easier path – it’s the right one.
Will creosote removal fix my smoky fireplace?
Creosote buildup is one of the most common causes of poor draft and smoke backing into the room – but it’s not the only one. Removing a heavy Stage 2 deposit from a flue can dramatically improve airflow and solve a smoking problem entirely. If draft issues persist after cleaning, the cause may be a flue that’s improperly sized for your firebox, a damaged liner, or a cap that’s restricting airflow. Our camera inspection before and after the cleaning is specifically designed to catch those secondary causes so you leave the visit with a full picture, not just a clean flue.
How long does creosote removal take?
Most Stage 1 and Stage 2 creosote removal jobs in Severna Park are completed in a single visit of two to three hours. Stage 3 glazed creosote removal can take longer – sometimes requiring an initial chemical treatment visit followed by a second mechanical cleaning once the product has had time to work on the deposits. We tell you upfront how many visits to expect and what the total cost will be before any work begins. Most jobs, including the Level 2 Inspection with camera and the cleanup, are done in one visit by the time we leave your driveway.
Why Severna Park Homeowners Call Hearthstone
Severna Park is not a place where people move in and move out. Most of the homeowners we serve in the Arnold Road corridor, the Chartwell neighborhoods, and the older streets off Ritchie Highway have been in their houses for fifteen, twenty, thirty years. They’re not looking for the cheapest option – they’ve already tried that contractor and they remember it. They want the job done right, documented, and backed by someone who will still be answering the phone if something comes up ninety days later.
That’s what the 90-Day Done Right Promise is. If the work we did isn’t right, we come back and make it right – in writing, no arguing, no paperwork shuffle. Russell Haines put his name on this company in 1984 and it’s still on the door forty-two years later. That’s the kind of accountability that doesn’t need to be sold.
Our technicians are background-checked and uniformed. They show up when we say they will. They document the job with photos you can see. And when the work is done, the number on the invoice matches the number on the estimate.
