If your Arlington home has a fireplace in a siding-clad box rather than a brick chimney, there is a metal chase cover on top of it, and in the newer Smokey Point neighborhoods and the plats around the freeway that cover is typically the original flat galvanized sheet the builder installed. Flat galvanized covers pond water, rust from the low spot and flue collar outward, and eventually drip into the chase. Replacement means measuring the chase, fabricating a stainless or heavy-gauge cover with a cross-break, a raised flue collar and a drip edge, and installing it sealed. Arlington is about 60 minutes from Renton; we measure on one route day and install on the next, or the same day when a stock size fits.
Chase cover replacement starts at $299. You get a free quote after we measure, a free second-opinion quote if another company already priced the job, and price match plus 10 to 25 percent off. If the chase framing under the old cover has rotted, we show you before we start; a chase rebuild starts at $299. If you are not happy, we are not done. Call 206-453-2045, or see chimney inspection if you are not sure what is on top of your chase.

- Standing water or rust pooling on top of the chimney after rain

- Soft, swollen, or peeling siding and trim near the top of the chase
- A cover that rattles or lifts at the edges in wind
- Visible rust holes or a sagging center in the metal lid
Arlington Conditions
Why this happens in Arlington
Arlington is hard on thin galvanized steel. Sea-Tac's NOAA normals, the regional reference, show roughly 150 to 156 days a year with measurable precipitation and November averaging 6.31 inches, the wettest month. A flat cover that ponds water stays wet for most of the year, and standing water typically rusts galvanized steel through at the low spot and the collar. The first visible sign in Arlington is typically orange streaks down the chase siding after the fall rains start; by the time water reaches the firebox the cover has typically been leaking for a season or more.
Tree shade and debris make it worse on Arlington's rural and wooded lots. Regional guidance says Western Washington moss spreads fastest October through April on shaded surfaces that dry slowly, and needles and moss on a flat cover hold water against the metal even longer. A cross-broken stainless cover sheds both water and debris, which is why we do not put flat galvanized covers back on Arlington chases.
How It Works
Our chimney chase cover replacement process
Measure the chase
We measure the chase, the flue pipe diameter and position, and the skirt height so the new cover fits without gaps.
Fabricate the cover
The replacement is made from stainless steel or aluminum with a cross-break, raised collar, and a drip-edge skirt over the siding.
Remove the old cover
The rusted lid comes off and we inspect and dry out the top plate. Minor wood damage is addressed before the new cover goes on.
Set and fasten
The new cover is fastened through the skirt into the sides of the chase, never through the top, and the collar is sealed to the flue pipe with high-temperature sealant.
Cap and check
We reinstall or replace the flue cap, confirm the storm collar is sealed, and photograph the finished top for you.

Chimney Chase Cover Replacement in Arlington — FAQ
What does rust on an Arlington chase cover mean for the inside of the chase?
Typically that water has already reached the framing. Rust streaks on the siding mean the cover has been wet through; the plywood and framing under it may be soft. When we measure for the new cover we check the chase top and tell you if a chase rebuild, starting at $299, is needed. Do not climb up; call 206-453-2045 for a free quote.
Why not just reinstall a galvanized cover in Arlington to save money?
Because it typically fails the same way within a few wet seasons. Stainless or heavy-gauge steel with a proper cross-break and collar costs little more, starting at $299 installed, sheds the rain and moss that Arlington gets from October through April, and comes with our not-happy-not-done guarantee. The free quote prices both so you can decide.
