A chimney sweep is the single most important thing you can do to keep a wood-burning fireplace or stove safe. Every time you burn wood, the smoke leaves behind creosote — a tar-like residue that coats the inside of the flue. Creosote is highly flammable, and enough of it is what turns a normal fire into a chimney fire. Indigo Chimney Sweep removes that buildup so your chimney drafts cleanly and vents smoke the way it should.
What a sweep includes
When our technician arrives in Joliet, the first step is protecting your home: drop cloths go down around the hearth and a HEPA vacuum runs the entire time to capture dust. We then brush the flue from top to bottom using rods and brushes sized to your specific liner, clearing soot, ash, and creosote from the smoke chamber, damper, and firebox. Loosened debris is vacuumed out, not left to settle into your living room.
Every sweep includes a visual Level 1 inspection so you know the condition of the chimney after it is clean. If we spot a cracked crown, a rusted damper, or a liner problem, we photograph it and explain your options — without pressure.
Signs your chimney needs sweeping
- A strong, smoky or campfire smell coming from the fireplace, especially in humid weather.
- Black, flaky or shiny buildup visible on the flue walls or damper.
- Smoke spilling back into the room when you light a fire.
- A damper that sticks or is coated in soot.
- It has simply been more than a year since your last cleaning.
Ignoring buildup does not just risk a chimney fire; a dirty flue also drafts poorly, which can push carbon monoxide back into the home. That is why the Chimney Safety Institute of America recommends sweeping once creosote reaches about one-eighth of an inch.

Frequently asked questions
How much creosote is dangerous?
The Chimney Safety Institute of America advises sweeping when creosote reaches about one-eighth of an inch. Glazed or thick creosote is especially hazardous and should be removed before you burn again.
How long does a chimney sweep take?
Most sweeps take 45 minutes to an hour and a half, depending on how much buildup is present and whether the flue is straight or offset.
Is chimney sweeping messy?
It should not be. We use drop cloths and a continuous HEPA vacuum, so the soot stays contained inside the equipment rather than spreading into your home.
Should I sweep before or after the burning season?
Either works. Many homeowners prefer late spring so acidic soot does not sit in the flue all summer, while others book in early fall before the first fire. The key is doing it once a year.
Can I sweep the chimney myself?
Store-bought brushes remove some soot, but they cannot reach the smoke chamber safely or spot structural problems. A professional sweep also includes an inspection, which is where most safety issues are caught.
Do gas fireplaces need sweeping?
Gas produces far less creosote, but the venting still collects debris and can develop blockages. We recommend an annual check — see our gas fireplace service page for details.
How do I prepare for the appointment?
Avoid using the fireplace for about 24 hours so the flue is cool, and clear a few feet of space around the hearth. We take care of the rest.
What does a sweep cost in Joliet?
Pricing depends on the appliance and its condition. See our pricing page for starting prices, or call (815) 296-9565 for a quote up front.
