Bellevue has more chase covers than it looks like it does. The 1980s homes that pushed the city's median build year to 1982 were among the first generation to use factory-built fireplaces in framed chases, and the post-2000 rebuilds almost all do, often behind stone or fiber-cement veneer that hides the chase. Those chases are topped with a sheet-metal cover, and on the 1980s homes that cover is typically the original galvanized pan, now decades old and pitted through at the low spots. On the rebuilds, covers are newer but are often large and flat, which pools water. Rust streaks on the chase, water in the firebox, or a damp smell from the fireplace in November are the usual signs.
We measure the chase, fabricate a stainless steel cover with a cross-break, drip edge, and sealed storm collar, and install it in one visit. Chase cover replacement starts at $299. The quote is free, we give a free second opinion on any existing quote, and we price match plus 10-25% off. Bellevue is about 20 minutes from our Renton office on I-405, so same-day service is often available. If you're not happy, we're not done.

Bellevue Conditions
Why this happens in Bellevue
A chase cover's job is to hold off 40.34 inches of rain a year, and in Bellevue roughly three-quarters of that arrives between October and March with November alone averaging 6.31 inches. A flat galvanized cover pools in the center and along the flue collar, and standing water through a Bellevue wet season is what eats through the zinc coating and then the steel. On a 1980s Bellevue home the cover has typically been through forty of those seasons, so a small leak found this year has usually been staining the chase framing for several.
Bellevue's rebuilds add a second failure path. A tall veneer chase on a 2010s home often has a wide cover with a large pipe penetration, and the storm collar sealant at that penetration typically dries and cracks after a few years of sun and rain. Shade from the city's mature trees keeps needles and moss on the cover October through April, holding moisture against the metal. Stainless does not corrode under that exposure, which is why we replace with stainless rather than patch.
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 Bellevue — FAQ
Our 1980s Bellevue home still has the original chase cover. Should we replace it before it leaks?
If it is the original galvanized cover, it is typically well past the point where rust has started, even if nothing shows inside yet. We can inspect it and tell you honestly whether it has life left or is pitting through. Replacing before the leak saves the chase framing and the fireplace below it. Replacement starts at $299, and the inspection and quote are free.
Can you replace the chase cover on a stone-veneer chimney in a rebuilt Bellevue home without disturbing the stone?
Yes. The cover sits on top of the chase and is removed and replaced from above, so the veneer is not touched. We fabricate the new stainless cover to the exact top dimensions with a drip edge that clears the stone, and seal the storm collar at the flue pipe. Bellevue is about 20 minutes from Renton, and same-day is often available. Starting at $299, free quote.
