Mercer Island, King County
On Mercer Island, each chimney on the house is inspected and billed on its own. The on-site inspection is $99 plus tax, and it is credited toward the work when you approve the written quote. Every visit ends with photos, a plain-language written report and, if something needs work, a written price you can take your time over. Nothing is repaired on the day unless you say so.

Most of the island's housing is detached: of roughly 10,570 homes counted around the 2020 census, 7,431 were single-unit. That means most chimneys here belong to one household, which also means nobody else is keeping an eye on them. An inspection is how you find out what the crown, flue and firebox look like before a problem shows up on the ceiling.
Water covers about half of Mercer Island's municipal area: King County describes Lake Washington as the largest of the county's three major lakes, and the lake wraps the island completely. On the roof, we look at which face of the chimney meets the prevailing weather.
The Western Regional Climate Center notes that western Washington's hardest blows in late fall and winter usually arrive out of the south or southwest. That side of the stack is where we look hardest for eroded mortar and lifted flashing.
Moss depends on moisture and shade, according to extension guidance from Oregon State, and WSU Extension notes it thrives through the three wet seasons on anything that stays damp. A green crown is a sign that the top of the chimney rarely dries out.
During an inspection we lift or look past the moss to the crown underneath and report any cracking we find. We do not recommend pressure washing a roof to clear it: OSU warns that it can damage shingles.
Every chimney inspection we do in Mercer Island includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowOn the island, the questions we get most are after a purchase, after a noticeable earthquake, or after a winter of leaks near the fireplace wall. Each points to a different depth of inspection. A home you have owned and used for years with no changes usually needs the routine level. A sale, a planned liner, a new stove or insert, or a shaking event calls for a closer look at the parts you cannot see from the hearth.
Mercer Island sits inside the Seattle fault zone, and the city reports that two or more of the fault's strands run across it. Washington DNR puts the chance of a magnitude 6.5 or larger deep earthquake in the Puget Sound region at 85 percent over the next 50 years.
CSIA recommends a Level 2 inspection after any weather or seismic event likely to have damaged a chimney. That level includes a video scan of the flue, because the cracks a quake leaves are often inside the liner where no one can see them from the hearth or the roof.
Pick a two-hour arrival window online or by phone. Tell us whether the fireplace burns wood or gas and whether anything has changed recently.
The technician starts at the firebox and damper, then looks up the flue with a light, and with a camera when the flue's condition calls for it.
Where the roof is safe to walk, we check the crown, cap, flashing and the brick above the roofline, and photograph anything worth discussing.
A written report with photos comes to you, along with an itemized quote if anything is found. The on-site inspection is $99 plus tax, and it is credited toward the work when you approve the written quote.
CSIA lists four low-cost defenses against water in a masonry chimney: a cap, a proper crown, sound flashing and a water repellent. It also advises a crown that overhangs the brick by about two inches on every side, so runoff drips clear of the walls.
Those are the four items we score on every island inspection. They matter here because the region's rainy season runs from October through winter, and in December and January rain falls on 20 to 25 days a month or more, per the Western Regional Climate Center.

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.
The standard, NFPA 211, sets out three. Level 1 fits a system that is staying as it is: the normal once-a-year check. Level 2 goes further, into attics, crawl spaces and roofs you can get to, with a camera run through the flue. Level 3 means removing components to reach hidden areas and is rare.
We did not find a state law that does. The Chimney Safety Institute of America advises a Level 2 whenever a home is sold, and many buyers ask for one, but it is an industry recommendation.
Per chimney. A house with a fireplace flue and a separate furnace or stove flue in another stack counts as two.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
