Understanding the Risks of Creosote


Creosote forms as a sticky residue from burning wood, becoming more hazardous as it accumulates in chimneys. Knowing its three stages helps in prevention, as it goes from initially sticky to a hardened, flammable mass, massively increasing the risk of fires.

Stage 1 Creosote: A light, flaky soot that brushes away easily with standard sweeping tools.

Stage 2 Creosote: A harder, tar-like coating that requires more aggressive removal techniques.

Stage 3 Creosote: A thick, glazed, and hard buildup that is extremely flammable and very difficult to remove with proper tools and chemicals.

Common Questions About Chimney Sweeping & Cleaning


Does a wood stove chimney need to be swept?

Yes, wood stoves and their venting systems require regular sweeping just like traditional open fireplaces, and often even more frequently. This is because wood stoves are typically operated at lower burn temperatures for extended periods to maximize heat efficiency, and cooler, slower fires produce more smoke and creosote than hot, open fires. That creosote accumulates rapidly inside the stove pipe and flue, creating a serious fire hazard if not removed regularly.

Additionally, wood stove venting systems have their own unique components and configurations that require knowledgeable servicing. Our technicians are experienced in cleaning and inspecting all types of wood stove systems, from freestanding stoves to fireplace inserts. We’ll remove creosote and debris from the entire venting path, check for proper drafting, and ensure your stove is operating safely and efficiently—keeping you warm and protected throughout Portland’s cold season.

What is glazed or third-degree creosote?

Glazed creosote, also called third-degree creosote, is the most dangerous and stubborn form of creosote buildup. It forms when creosote accumulates and is repeatedly heated and cooled, eventually hardening into a thick, shiny, tar-like coating that clings tightly to the flue walls. Unlike first-stage flaky soot or second-stage crunchy buildup, glazed creosote cannot be removed with standard brushing – it requires specialized tools, chemical treatments, or rotary cleaning systems to safely break down and eliminate.

What makes glazed creosote especially hazardous is that it’s extremely concentrated and highly flammable… When it ignites, it burns hot and long, fueling intense chimney fires. Its presence is a serious warning sign that your chimney needs immediate professional attention. This is precisely why professional sweeping matters so much.

Will sweeping my chimney improve its efficiency? 

Yes, a clean chimney performs noticeably better than a dirty one. When creosote and soot accumulate inside your flue, they narrow the passage and restrict airflow, which weakens your chimney’s draft – the natural process that pulls air up and out, feeding oxygen to your fire and carrying smoke away. A restricted flue means your fires are harder to start, burn less completely, produce more smoke, and generate less usable heat, all while wasting fuel.

After a thorough sweeping, your flue is clear and drafting properly, so you’ll enjoy easier lighting, hotter and cleaner-burning fires, less smoke escaping into your room, and better heat output from the same amount of wood. In short, regular sweeping doesn’t just improve safety – it makes your fireplace or stove more enjoyable, more efficient, and more economical to operate.

How do I prepare my home for a chimney sweeping appointment?

Preparing for your appointment is simple and takes just a few minutes. First and most importantly, make sure your fireplace or wood stove has been completely cold for at least 24 hours before we arrive, since we can’t safely clean a warm or recently used system. Next, remove any decorative items, screens, tools, or belongings from the mantel, hearth, and the area immediately surrounding the fireplace, and clear a direct path from the entrance to the fireplace so our team can move equipment easily.

If you have any fragile furniture or valuables nearby, you may want to move them a bit further away as a precaution, though we’ll lay down protective coverings regardless. Finally, if you have pets, it’s a good idea to keep them secured in another room for their safety and comfort while we work. Beyond these simple steps, our team handles everything else, including all cleanup.

Can I sweep or clean my chimney myself?

This is not recommended. DIY chimney cleaning kits are available, so we get why this question comes up – but it’s important to note that these come with significant limitations. Consumer-grade brushes and rods may handle light surface soot, but they aren’t equipped to address heavier creosote deposits, blockages buried deep in the flue, or buildup in the smoke chamber.

Beyond the cleaning itself, a professional sweep has the training to recognize potential hazards (like cracks in the liner, damaged components, or early signs of moisture intrusion) that an untrained eye would likely miss. For a job that directly affects your home’s fire safety, professional servicing is the right call.

What type of wood should I burn to keep my chimney cleaner?

Seasoned hardwood is the best choice for a cleaner-burning fire and reduced creosote buildup. In addition, hardwoods – like oak, maple, ash, and cherry – burn hotter and produce less residue than softwoods.

Why? Because soft, wet, or freshly cut wood has a higher moisture content that causes smoldering, incomplete combustion, and significantly more smoke and fumes. All firewood should be split and dried for at least six months (ideally a full year) before burning. Burning treated wood, cardboard, or household garbage is never recommended, as these materials produce harmful chemicals and accelerate buildup inside the flue.
