Creosote comes in grades. Powdery soot brushes away. A crunchy, flaked layer takes more effort but still yields. The third grade is different: a flue that runs cool and smoky bakes its deposits into a glossy, tar-black shell, and a brush only polishes it. This service exists for that shell. A camera shows us how much there is and at what height, a remover is applied to break its grip on the liner, and rotary equipment lifts it without hammering the tile beneath. Then the camera goes back up.
The heaviest glaze we see belongs to stoves that heat a house full-time, and on our map those cluster on rural lots near Hobart and Maple Valley more than in the cities. Owners there should know the burn-ban rule: burning during an air quality ban is allowed only when wood is the home's one adequate heat source and an exemption was obtained beforehand from the Puget Sound Clean Air Agency. Exempt or not, the chimney must show no visible smoke, and a glazed flue makes a clean burn hard to achieve.
CSIA's guidance is to sweep a masonry fireplace at 1/8 inch of sooty buildup and sooner if any glaze is present. That last clause is there because glaze is concentrated fuel bonded to the liner, and ordinary sweeping leaves it in place.
A flue lined with glaze is a chimney fire waiting for a hot enough evening, and such a fire burns long enough to split clay tile. Keeping glaze from forming is mostly a matter of what goes into the firebox. The state permits two fuels: wood that is dry and seasoned, and manufactured logs. Its rule WAC 173-433-120 bans a list of others from the firebox, among them garbage, plastics, rubber, treated lumber, paint, chemicals and petroleum or asphalt waste, and several of those leave sticky residues on a liner in addition to fouling the air. Damp wood and a throttled air supply do the rest: they cool the smoke until it condenses on the flue walls.
How it works
Soot, flake or glaze, and how many feet of it: the camera settles both.
The remover needs time to change the glaze so it lets go of the tile.
Rotary heads clear the softened layer; a stubborn flue may get a second treatment.
Tiles that were hidden for years are finally visible, cracks included.

A sweep ($189–$459) removes soot and flaky creosote with brushes. Creosote removal, quoted from $245, brings in a chemical remover and rotary tools for the glazed kind. How much glaze there is, and over what length of flue, sets the final figure.
That is how chimney fires happen. Setting the glaze alight deliberately risks cracked tiles and worse. We remove it with the flue cold.
As a help with light deposits, somewhat: they can dry soot so that brushes take it more easily. They do not replace sweeping and they will not strip glaze.
Dry, seasoned wood, enough air for a lively flame, and no all-night smoldering. Add the yearly inspection so the deposit is caught while a brush can still deal with it.
The sequence is designed to prevent that. Chemistry loosens the glaze first, so the tools are lifting material that has already released. Any crack the glaze was hiding will show in the closing photos.
