Chimney Sweeping
Creosote Removal Northbrook, IL
A Northbrook chimney sweep can take creosote out of a fireplace or stove flue, before it thickens into the fuel for a chimney fire. One call to (224) 458-2675 reaches a chimney sweep near you.
Every wood fire sends gases, moisture and unburned particles up the flue, and when they cool they stick to the walls as creosote. It is highly flammable, and a thick enough layer can ignite and burn hot enough to crack flue tiles. Keeping it under control is the main reason chimneys need regular sweeping.
Not all creosote is the same, and the stage decides how it comes out. First stage creosote is light and sooty and comes off with an ordinary brush. Stage 2 is crunchy, black and porous, a bit like puffed tar, and needs stiffer brushes or rotary tools. Third stage glaze is thick, shiny and tar-like, and it takes chemical treatment or specialized tools to remove.
Certain conditions make creosote build up much faster. Wood with too much moisture, low smoky fires and restricted air make the most creosote. An oversized or uninsulated flue lets smoke cool and condense sooner.
If the problem goes deeper than it first looked, a Northbrook chimney sweep may also recommend chimney cleaning or chimney fire damage repair.

The creosote removal process
The method depends on the stage of creosote and the type of liner.
Look inside
The technician checks the deposits with a light and often a camera to see how thick they are and which stage they have reached since that decides the tools.
Set up
The hearth is covered and a fine-filter vacuum runs at the opening so dust stays contained.
Rod brushing
Flaky soot and lighter crunchy deposits are brushed out and drop into the firebox to be vacuumed.
Power sweeping
Heavier stage 2 deposits are broken up with rotary cleaning heads, flexible whips spun by a drill chosen so they do not damage the liner.
Chemical treatment
For glazed buildup, a chemical treatment is applied and left to work so the deposit can be brushed out later and then removed with brushes or rotary tools.
Review the flue
Once the creosote is out, the technician checks the flue for damage underneath and explains what caused the buildup.
What is included
Where creosote gets removed
Spark arrestors
Spark arrestor screens on the cap are cleared of buildup since a clogged screen chokes the draft.
Smoke shelf
The smoke chamber is cleaned by hand, since brushes miss its corners including any fallen flakes.
Stage 3 glaze
Stage 3 creosote is treated so it can be removed over one or more visits.
Masonry flues
Clay tile and masonry flues are cleared of creosote from the smoke chamber to the top including the corners of rectangular tile.

Glazed Creosote Removal Northbrook, IL
Glazed creosote is the most concentrated form of creosote, and it clings to the liner as a smooth, hard coating. It forms when creosote is heated over and over without being removed, often in flues with smoldering fires or restricted air. It burns hot enough to crack tile liners, and a standard brush cannot remove it.
Most sweeps treat glaze with a modifier that turns it into a flaky, removable form over days or weeks. Heavy glaze may need several applications and more than one visit, and rotary chain tools are only used on liners that can handle them. If a camera scan shows the liner is already cracked under the glaze, a new stainless steel liner may be the safer fix.

Chimneys in this climate
This part of the country gets long winters, heavy snow in places and stretches of bitter cold. Heating systems and wood stoves work nearly nonstop for months, which means fast creosote buildup and a lot of stress on liners, crowns and flashing. Snow drifting against the back of a chimney melts slowly and works water under tired flashing. Most chimney cleaning in Northbrook, IL happens right before the first snow.

Common questions about creosote removal
How often does a chimney need creosote removal?
Creosote should come out whenever an inspection finds buildup, and at least once a year for chimneys burned regularly. Many sweeps clean once deposits reach about an eighth of an inch, and any glaze should come out right away. Daily wood stove use often means cleaning more than once a year.
How dangerous is creosote buildup?
Creosote is highly flammable, and it is what burns in a chimney fire. Once lit, it burns very hot, which can crack the liner and threaten the house. If you hear a loud roar or rapid popping in the chimney, get everyone out and call 911.
Is creosote removal a do it yourself job?
Light, flaky soot in an easy flue can be brushed by a careful homeowner, but most creosote work is best left to a sweep. Roof work, containing the dust and spotting damage under the deposits are where a sweep makes the difference. Treatment logs only loosen deposits and leave them in the flue.
Why does my chimney get so much creosote?
Fast buildup comes down to cool, smoky fires and cold flues. Burning wood that is not seasoned, closing the air controls too far and letting fires smolder are the biggest causes. A flue that is too wide or too cold also lets smoke condense sooner.
How can I tell what stage of creosote I have?
The first stage is light, sooty and easy to sweep. At stage 2, the deposits are crunchy and tar-like and need rotary tools or stiff brushes. Stage 3 is a hard, shiny glaze that looks like dripping tar and needs chemical treatment to remove. A sweep can tell you which you have after a look up the flue.
