Most Mercer Island fireplaces we sweep are original to the house: a brick firebox with a clay tile flue in a 1950s-70s rambler or split-level, often on an outside wall facing the lake. A flue like that runs cool, and cool flues collect creosote faster than warm interior ones, so a few winters of evening fires leaves a hard glaze in the upper tiles. Newer homes and the rebuilt lots along East Mercer Way and West Mercer Way typically have factory-built wood fireplaces with metal flues, which sweep quickly but whose spark screens pack solid with soot and need clearing.
Our sweep and inspection starts at $299. We brush the flue with the right size brush for tile or metal, vacuum the firebox and smoke shelf, and run a camera up the flue so you can see the result and spot any cracked tile. We drive over from North Renton on I-90 in about 20 minutes and can usually fit an island sweep into the same day. If you have a quote from another sweep, ours is free and we price match and take 10 to 25 percent off. If you are not happy, we are not done.

Mercer Island Conditions
Why this happens in Mercer Island
Island fireplaces get a long season. The wet months from October through March bring about 73 percent of the area's rain, and with winter lows averaging 37-38F most homeowners around Mercerdale and the Town Center keep a fire going on weeknights rather than only on holidays. Short, frequent burns in a cool tile flue are exactly the pattern that deposits glazed creosote, which is why an island flue that has gone two or three winters without a sweep takes more passes than a suburban one.
The lake adds humidity. A chimney that sits damp between fires, especially one on a shaded lot near Luther Burbank Park or Pioneer Park, lets creosote absorb moisture and bond to the tile. That is why we suggest sweeping in July or August, the two driest months at 0.60 and 0.97 inches, when the flue is dry and the deposits come off cleanest.
How It Works
Our chimney sweep process
Protect the room
Drop cloths from the door to the hearth, a sealed fireplace opening, and a HEPA vacuum running the whole time so dust stays out of your living room.
Inspect first
A visual check of the firebox, damper, smoke chamber and flue confirms a routine sweep is the right service.
Sweep the flue
We run brushes sized to your chimney, from the firebox up or from the top down depending on the system, to knock creosote and soot off the flue walls.
Clean the smoke chamber, shelf and damper
The smoke shelf collects most of the loose fall; we brush and vacuum it and the smoke chamber, then brush the damper so it seats properly.
Final check and walkthrough
We look up the flue again, vacuum the firebox, and show you what came out. Anything we noted, such as cracks or a missing cap, gets a free written quote.

Chimney Sweep in Mercer Island — FAQ
Do you sweep the fireplaces in Mercer Island condos and townhomes?
Yes, if the unit is wood-burning. Most condo fireplaces near the Town Center and along 78th Ave SE are factory-built with metal flues, which sweep fast. We coordinate roof access with the HOA or property manager and can do several units on one visit, which keeps the cost per unit down.
How often should an older Mercer Island tile flue be swept?
NFPA 211 recommends an inspection every year, and the inspection tells us whether a sweep is due. A mid-century exterior tile flue used most winter evenings typically needs sweeping annually. A flue used a handful of times may not. Our $299 sweep and inspection includes the camera check either way.
How soon can you do chimney sweep in Mercer Island?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Mercer Island and the rest of King County.
