Redmond, King County
A chimney sweep in Redmond costs $189 to $449. A single-story roof and one season of soot sit at the low figure; a steep pitch on Education Hill, a tall flue or several winters of deposit move the job upward. Every sweep ends with photos of the flue and a short written note on what we saw.

Redmond burns less wood than its size suggests. The Census counts about 72 households that heat mainly with wood, out of 33,100 occupied homes, so nearly every fireplace we brush here is lit for evenings and weekends, not for daily heat. That pattern hides soot: a flue used twenty nights a year can go a long time before anyone looks up it.
Census estimates put 8,224 of Redmond's 35,104 housing units, about 23.4%, in the 1960 to 1979 building years. That is the period when the city took in Overlake (1962), Viewpoint (1964) and Bear Creek (1966), after adding 332 acres of Education Hill in 1951.
A fireplace from those decades may have had an insert slid into it since, and an insert changes how a sweep is done: the soot gathers where the insert meets the old flue, out of sight from the room. We ask what is installed before we quote, and we do not assume a chimney type from the street it is on.
Every chimney sweep we do in Redmond includes:

Book nowFor Redmond, WeatherSpark's model shows about 6.8 months of wetter weather, October 9 through May 2. November leads with some 8.7 inches of rain. Wood stacked outdoors through that stretch stays damp, and damp wood smolders and coats the flue faster than dry wood does. In Washington's 2024 figures, published by the State Fire Marshal, chimney and flue fires account for 77% of residential-building fires that began with heating equipment.
Redmond's hazard annex records that a magnitude 4.6 earthquake near Monroe in 2019, about 20 miles off, was felt in the city. Small events like that rarely make news, yet a flue tile can shift or crack without any sign at the hearth.
Soot hides those cracks. Once the liner is brushed bare we photograph every joint we can reach, which is the practical moment to learn whether the last tremor left a mark. For the Puget Sound region, Washington DNR's 50-year estimate is 85% for a deep quake reaching magnitude 6.5.
Drop cloths go down between your front door and the fireplace. The vacuum hose is then taped across the opening, and only after that does a brush come out.
Rods and a brush sized to your flue work the whole run, from the firebox up or from the roof down, depending on the pitch and the weather that day.
The shelf behind the damper collects what the brush knocks loose. We empty it by hand and vacuum.
With the soot gone, the liner, the damper and the firebox joints are visible. We photograph anything cracked, missing or glazed.
The photos are yours, along with a short verdict in writing: fine to burn, or what needs attention and its written price.

Brushing a flue installs nothing, and the fixture list on Redmond's mechanical permit application is a list of things installed: Fireplace, Gas Logs Insert, Wood Pellet Stove or Insert, Gas Appliance and others.
So the permit question only opens if the sweep leads somewhere, for example toward a new insert. In that case the city handles trade permits through REPS, its ePermitting service, or in person at 15670 NE 85th Street. The same form says a contractor needs a Redmond business license in hand prior to starting.
Redmond is a city of a little over 17 square miles around the northern tip of Lake Sammamish, on the Sammamish River, with homes with a median build year of 1993, close to a quarter of them built in the 1960s and 1970s. We work every part of it — Education Hill, Grass Lawn, Idylwood, North Redmond, Overlake included.

Four steps, each one on paper — so you always know what happens next.
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.
$189 to $449. Roof pitch, flue height and how much deposit is waiting decide where your chimney lands, and we tell you the figure before we start.
Go by thickness, not the calendar. CSIA's homeowner guidance sets 1/8 inch of sooty deposit as the point where a masonry fireplace is due, and any shiny glaze as a reason to act earlier. The yearly look that NFPA 211 asks for is how you find out.
No. Redmond is inside the Puget Sound Clean Air Agency's territory. When the agency calls Stage 1, a wood fireplace stays cold, and so does any uncertified stove or insert; the lone exception is a household holding the agency's approved exemption for having no other adequate heat. A freshly brushed flue changes none of this.
We stop, show you the photos and offer a full look at the system for $99 plus tax. Approve the written repair quote afterwards and those $99 are subtracted from it.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
