Every time you burn wood, the smoke leaves behind a residue called creosote on the inside of your flue. It builds up in layers, and it is highly flammable — creosote is the fuel behind most chimney fires. You cannot see it from the living room, which is exactly why it is dangerous: the buildup grows quietly, season after season, until a hot fire ignites it. A professional chimney sweep removes that buildup before it becomes a hazard.

Global Chimney Sweep provides thorough, low-mess sweeping for homeowners across Mokena and the south suburbs. We are an owner-operated company, so the person brushing your flue is an experienced technician who has done it thousands of times — not a rushed subcontractor. You get a clean chimney, an honest heads-up on anything that needs attention, and a price you agreed to before we started.

What a Chimney Sweep Includes

Full Flue Brushing

We brush the entire flue from top to bottom, removing creosote and soot from the liner walls, the smoke chamber, and the damper area.

HEPA Vacuum Containment

A HEPA-filtered vacuum runs the whole time to capture dust and keep it out of your living room. Drop cloths and shoe covers protect the rest.

Basic Safety Check

While we are in there, we visually check the flue, damper, smoke chamber, and firebox and flag anything that looks worn or unsafe.

Photos & Plain-English Summary

If we find a problem, we show you a photo and explain it in plain terms — no jargon, no pressure to buy anything.

Signs It Is Time for a Sweep

Book a sweep if you notice any of these: a strong, smoky or barbecue-like smell coming from the fireplace even when it is cold; black, flaky buildup you can see or scrape inside the firebox or on the damper; smoke pushing back into the room when you light a fire; or simply the fact that a full year has gone by since your last one. The Chimney Safety Institute of America recommends an annual sweep and inspection for anyone who burns wood, and more often if you burn frequently or use wood that has not been properly seasoned.

Frequently Asked Questions

How often should I have my chimney swept?

Once a year is the standard recommendation for anyone who burns wood, ideally before the heating season starts. If you burn most nights through the winter or use unseasoned wood, you may need a second sweep partway through the season. Gas fireplaces need less frequent sweeping but still benefit from an annual inspection.

How long does a sweep take?

A routine sweep and Level 1 inspection on a single flue in good condition usually takes about 45 minutes to an hour. Heavy creosote buildup, a second flue, or a chimney that is hard to access from the roof can add time. We will give you a realistic window when you book.

Will sweeping make a mess in my house?

No. We run a HEPA-filtered vacuum the entire time and lay down drop cloths around the fireplace, so the soot and dust are contained at the source. Most customers are surprised at how clean the area is when we finish.

Do I need to do anything to prepare?

Just make sure the fireplace is cold — do not burn a fire for at least 24 hours before the appointment — and clear a few feet of space in front of it. If you have pets, it helps to keep them in another room while we work.

What is creosote and why does it matter?

Creosote is the tar-like residue that wood smoke leaves inside your flue. It builds up in layers and is highly flammable, which makes it the leading cause of chimney fires. Regular sweeping removes it before it reaches a dangerous thickness.

Can you sweep a chimney I have not used in years?

Yes, and it is a good idea before you start using it again. An unused chimney can collect animal nests, debris, and moisture damage on top of old creosote. We will sweep it and inspect it so you know it is safe to light before you strike the first match.

Is a gas fireplace chimney swept the same way?

Not exactly. Gas fireplaces produce far less creosote than wood, so they do not need the same heavy brushing, but the flue and venting still need inspection and cleaning of debris and soot. We handle gas units through our gas fireplace service, which is tailored to how they burn.

Do you sweep chimneys year-round or only in fall?

We sweep year-round. Fall is our busiest season because everyone books before winter, so scheduling in spring or summer often means faster availability and a chimney that is ready well before the first cold night.
