Issaquah, King County
Installed, an Issaquah chimney cap costs $235–$845. The low end is a stock stainless cap on one round flue; a wide crown covering several flues, or a cap made to measure, sits toward the top. We measure on the roof and give you the exact figure.

An uncapped flue is open to everything that falls from the sky, and here that is mostly rain. Birds and small animals looking for a dry, sheltered spot are the next problem, followed by leaves and debris dropping in from trees near the house. A cap with a screen stops all three at the top.
Every chimney cap installation we do in Issaquah includes:
Smoke coming back into the room, or a smell that won't go? Book the inspection first.
Book nowThe caps we replace in Issaquah are usually one of three kinds: a painted steel cap that has rusted through, a cap too small for a flue that was relined at a larger size, or a screen so clogged it chokes the draft. The last one is easy to miss from the ground until the fire starts to smoke.
Where a chimney has a spark arrestor, the Washington residential code spells out what it must be: a screen of corrosion-resistant material, openings no larger than 1/2 inch, a net free area of at least four times the flue outlet, and a top that can be taken off so the screen can be cleaned. A cheap mesh that fails any of those is not doing its job.
Fire weather here is a summer story. The Puget Sound Clean Air Agency notes that wildfires affecting the region typically occur in the warmer, drier months, and in August 2023 smoke from them pushed King County's fine-particle levels above the agency's health goal on 3 days. For houses close to trees, a well-sized screen on the chimney is a sensible precaution.
We measure every flue tile and the crown so the cap sits square and the mesh clears the flue outlet by the required margin.
A single-flue cap clamps to the tile; a crown-mount cap covers several flues at once. We show you both when both would work.
We anchor the new cap firmly enough to ride out a winter gale, and haul the old one away rather than leaving it in your yard waste.
If the fireplace is ready to light, we check that smoke rises cleanly through the new screen before we leave.

The Chimney Safety Institute of America names a cap first on its short list of cheap ways to keep water out; the others are a well-built crown, tight flashing and a masonry repellent. An open flue lets rain fall straight onto the damper and the smoke shelf, where it rusts metal and softens mortar out of sight.
That matters more in a place with a long wet season. Monthly averages for Issaquah show November as the rainiest month and July as the driest, which makes the dry summer the best window to put a cap on before the fall storms.
Issaquah is a city nestled against the Issaquah Alps, with a historic downtown plus large newer developments in the highlands. We work every part of it — Gilman, Issaquah Highlands, Squak Valley included.

$235–$845 installed, depending on flue count, size and whether a standard cap fits. You receive the price after we measure.
The Washington residential code does not make one mandatory for every chimney, but where a spark arrestor is used it sets clear dimensions for it. Ours are built to those numbers.
We tell you before we install. A cap on a failing crown only hides the problem. Crown work can be quoted at the same visit, or you can book an inspection first. The on-site inspection is $99 plus tax, and it is credited toward the work when you approve the written quote.
