Duvall, King County
Cleaning a dryer vent in Duvall costs $105 to $265. At $105: a few feet of duct going straight out through a first-floor wall. Toward $265 you find roof exits, second-story laundry rooms and ducts with a bird's nest inside. The price is agreed once we have seen where the duct goes.

Duvall is a town of houses with their own laundry rooms. The state's housing estimate for April 2026 lists 2,598 one-unit structures out of 3,198 housing units, and nearly half of the housing was built since 2000. A laundry room upstairs, or far from an outside wall, means the duct is longer and takes more turns before it reaches daylight.
Duvall's heating profile, as the Census sketches it: gas first at 60.0 percent of occupied homes, electricity second, and wood as the main fuel for an estimated 4.5 percent, a small-sample figure that nonetheless tops our other three towns.
In a house with a wood stove, the dryer and the stove compete for air. A dryer pushes a large volume of indoor air outside on every cycle, and Washington's code requires that exhaust to be discharged outside, three feet or more away from building openings. A duct that is clear and properly terminated does its job quickly, so the machine runs for less time alongside the stove.
Every dryer vent cleaning we do in Duvall includes:

Book nowLength is regulated. Washington's residential code caps a four-inch metal dryer duct at 35 feet and deducts five feet per 90-degree elbow. It also requires a backdraft damper and forbids a screen at the outlet, because a screen collects lint. A duct that is too long, kinked or screened dries slowly and runs hot. Nationally, USFA estimates 2,900 residential dryer fires a year, with failure to clean the leading factor at 34 percent.
A burn ban stops more than stoves. Under the Clean Air Agency's rules all outdoor burning is prohibited while one is in effect, and the agency's 2024 summary counted 105 moderate air days in King County alongside four rated unhealthy for sensitive groups.
On poor-air days windows stay shut, and the dryer vent becomes one of the few places indoor air leaves the house. The agency's status page, map and alert sign-up tell you when a ban is on. A vent cleaned before winter is one less thing running badly behind closed windows.
We find the outlet, count the bends and measure how far the duct travels.
A rotating brush works through the duct while suction pulls the lint out, not into the house.
The hose at the dryer and the hood outside are cleaned, and a stuck damper is freed.
A reading at the outlet confirms the duct is moving air again; you get the figure.

In January, according to USFA's report on residential dryer fires. Here that is also deep in the wet season, when little laundry dries outdoors and the machine runs most.
It is allowed, but it is harder to keep clean and costs more to service, toward the $265 end. We check the roof cap's damper and remove any screen someone added.
We measure it and count the elbows during the visit. The code allowance is 35 feet minus five per right-angle bend; if yours exceeds it, we explain the options.
