Kenmore, King County
A chimney cap in Kenmore costs $235 to $850 installed. One round or square flue under a stainless cap is the cheaper case; a made-to-measure cover straddling several flues on a wide brick crown is the costly one. Sizes are taken up on the crown itself; we never order a cap from a picture.

Plenty of Kenmore chimneys were built with no cap at all, or have a painted steel one from decades ago that has rusted thin. On a stack beside tall trees, an open flue collects needles, leaves and, in spring, nesting material. On any stack, an uncapped top also lets rain drop onto the damper and pool in the smoke chamber.
A 2010-2011 King County survey found 12 Parade of Homes houses in Kenmore built between 1955 and 1959, among 93 mid-century homes it documented, most of them Ranch or Split Level.
Census estimates add that about 62.7 percent of Kenmore's housing units are single-family detached homes, so most chimneys here belong to a single household, each with its own stack to cap. On brick fireplaces of that period, the original top was often just an open tile sticking out of the crown.
Every chimney cap installation we do in Kenmore includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowRain entering an uncapped flue rusts the damper, softens the mortar in the smoke chamber and can leave a musty smell in the room during wet weeks. Birds and small animals move into open flues during the dry season and are often discovered only when the first fire of autumn fills the room with smoke.
Swamp Creek's lower reaches run past homes and businesses in the Kenmore and Bothell area before joining the Sammamish River just upstream of Lake Washington. The creek supports chinook, sockeye, kokanee and coho salmon as well as steelhead trout.
Creeks, river banks and a lakeshore make for a lot of wildlife close to houses. Around that much water, a screened cap is the simplest way to keep nesting birds and small animals out of a flue.
A tape measure on each tile and over the full crown, plus a look at whether that concrete is solid enough to anchor a cap.
Any nest or debris is removed from the top of the flue before the cap goes on, so nothing is trapped underneath.
Fasteners go into the flue tile or the crown, depending on the model, so a December gust stays a gust.
We confirm the screen is clear of the flue outlet and send you photos of the finished installation.

Section R1003.9.2 of Washington's 2021 residential code governs spark arrestors wherever one is fitted. Its open area has to be no less than four times that of the flue outlet; its mesh has to hold up against heat and corrosion, with 19-gauge galvanized and 24-gauge stainless named as examples; a 1/2-inch sphere must not pass its openings, though a 3/8-inch one must; and it has to be removable so the flue can be cleaned.
The Washington State Fire Marshal also recommends a chimney cap alongside yearly professional inspection and cleaning. We fit caps that meet the screen rules above, and that lift off when the flue needs sweeping.
Kenmore is a city on the northernmost shore of Lake Washington, where the Sammamish River meets the lake, on Lake Washington, with Ranch and Split Level houses from the 1950s and early 1960s beside newer homes, for a median build year of 1985. We work every part of it — Uplake Terrace 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.
$235 to $850 installed. Flue count, crown size and whether the cap is standard or made to measure decide the figure, which you get before we climb up to fit it.
It stops rain going down the flue. Leaks through the brick, the crown or the flashing need their own fix, and we tell you if we see one while we are up there.
Yes. A multi-flue cover sits on the crown and protects every flue under it, which is often simpler than separate caps on a wide stack.
A $99 on-site inspection, a written quote before any work, and photos of every item we touch.
