Phinney Ridge, King County
Removing creosote from a Phinney Ridge flue costs $245 and up. The starting price applies to a heavy but still brushable deposit in a flue of ordinary height. Glazed creosote, the hard shiny kind, costs more because it cannot simply be brushed: it has to be treated chemically, sometimes over more than one visit, before it will come off the tile. The camera tells us which kind you have, and you hear the price before treatment begins.

Wood is seldom the main fuel on the ridge. Citywide, the 2020 to 2024 census estimates turn up just 727 Seattle households, 0.2%, naming wood as their primary heat, and the share is no higher than 0.5% in any North Seattle ZIP area. Fireplaces here are for evenings, and that pattern has a side effect: short, cool fires in a big masonry flue never warm it through. Smoke meets cold tile and condenses. A fireplace lit twenty times a winter in that manner can build a worse deposit than a stove burned hot every day.
Every creosote removal we do in Phinney Ridge includes:

Two fuels are legal in a Seattle hearth or stove under Puget Sound Clean Air Agency rules: seasoned firewood, properly dry, and logs of the manufactured kind. Household garbage, plastics and treated lumber are off limits, and so is paper past the few sheets that start a fire. Wet or unseasoned wood is the classic creosote maker, because so much of its heat goes into boiling off water that the smoke leaves the firebox cool. Outside burn bans the agency also holds chimney smoke to 20% opacity, measured across six consecutive minutes in any hour; a flue that smokes heavily is usually a flue that is coating itself.
Creosote is condensed smoke, and condensation depends on how cold the flue is. WeatherSpark's Seattle averages put December highs at 47°F and lows at 38°F, and describe a January in which seven hours in ten are overcast or nearly so (71%). A masonry chimney on an outside wall sits at roughly that temperature until a fire has burned long enough to heat it. No separate readings exist for the ridge.
Add water and the deposit worsens. Rain blown into an uncapped flue soaks the creosote already there, and the mixture is acidic enough to attack mortar joints between tiles. Seattle's emergency management office points out that wind accelerates over ridges, so an open flue on high ground takes in more than a sheltered one. Removal deals with what has built up. A cap, dry wood and hotter, shorter-smoldering fires are what keep it from returning at the same rate.
The camera shows whether the creosote is sooty, crusted or glazed, and how far up it extends.
Loose and crusted material is taken out with rotary equipment under vacuum.
A product is applied that alters the hardened layer so it can be removed. It needs time to act, sometimes days.
The treated deposit is brushed out, and the camera goes back up to check the tile underneath.

From $245. Brushable deposits stay near that figure; glazed creosote requiring chemical treatment and return visits costs more, and we quote it once the camera has shown its extent.
Yes. The Chimney Safety Institute of America explains that crusty creosote can be removed by rotary cleaning, whereas the gummy or glazed form needs chemical treatment to change its makeup before brushing will work.
No. Trying to burn creosote out is how chimney fires start. Should the flue start to roar, close the damper if you safely can, leave the house and call 911.
Then cleaning has done its job by revealing it. Assessing the flue is an inspection, charged $99 plus tax per chimney and counted against the cost of any repair you sign off on.
