Duvall, King County
Sweeping a chimney in Duvall costs $189 to $449 with us. A single straight flue on a walkable roof sits at the low end; a steep pitch on the hillside, a tall stack or a stove pipe that has to come apart moves the figure up. You get the number before any brush leaves the truck.

Duvall is a young town on paper. The Census puts the median home at the year 2000, and fewer than one unit in twenty predates 1980. A newer house does not mean a clean flue, though. What fills a chimney is fuel and hours of burning, and a larger share of households here name wood as their main heat than in the three other towns on our route.
Census estimates put wood as the main heating fuel in roughly 125 of Duvall's 2,787 occupied homes, about 4.5 percent. The margin of error is wide, plus or minus 113 households, but the direction is clear: King County as a whole sits near 0.6 percent.
A flue that carries the house's heat for months sees far more smoke than one lit on a few holiday evenings. Ecology's advice on fuel is specific: split the wood, cover it, stack it, then leave it a full year or longer. Greener logs burn cooler and leave heavier deposits for the brush.
Every chimney sweep we do in Duvall includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowOf the residential heating fires Washington logged in 2024, 77 percent began in a chimney or a flue. The figure is from the State Fire Marshal's September 2026 release, which also tells owners to book a professional cleaning every year. In a stove that runs from mid-November into March, soot does not wait for the calendar: the trade's own rule is to sweep once the deposit reaches an eighth of an inch.
Puget Sound Clean Air Agency holds any chimney to the same limit year round: a 20 percent opacity ceiling, which the plume may not exceed six minutes in a row within any single hour. Fuel is restricted too, to seasoned dry wood and manufactured logs.
A clean flue drafts harder and helps a fire reach that clear-stack point sooner after lighting. Under Stage 1 of a ban, open fireplaces go cold along with every uncertified stove and insert; Stage 2 adds certified units and pellet stoves.
Floors get covered between the door and the hearth; the vacuum starts first, the brush second.
We work from the roof or from the firebox, whichever the pitch and the weather allow, until the liner walls show.
Soot on the smoke shelf, behind the damper and in the stove's baffle area is removed, not pushed aside.

Choose a genuine opening on the crew's calendar. Confirmation is immediate.
Liner, crown, cap, flashing and masonry examined in order — each finding photographed.
One document, plain numbers, covering only the work your chimney genuinely needs.
The repair is completed, then handed over with before-and-after photos of every item.
Once a year at minimum, per the NFPA 211 wording CSIA quotes. A stove carrying the whole heating load may need a mid-season pass as well; an eighth of an inch of soot is the trigger.
Yes. A ban restricts burning, not cleaning, and a cold flue is the easiest one to brush.
We photograph it and price the repair in writing. Should a full camera inspection be needed, that visit is $99 plus tax, and the amount comes off the repair quote once you approve it.
