We'll confirm a time by phone or text.
Sumner's downtown is old, but the subdivisions east of SR 410 and up the hill toward Lake Tapps were mostly built in the 1990s and later, and those homes typically have factory-built fireplaces inside a siding-wrapped framed chase. The metal lid on that chase is the chase cover, and the galvanized ones builders used typically rust through at the seams and around the flue collar after years of valley rain. Homeowners usually notice rust streaks down the siding first, then a water stain on the ceiling beside the fireplace, and by that point the plywood and framing inside the chase have often been wet for a season or two.
We fabricate a stainless steel replacement measured to your chase, with a cross-break so water sheds instead of pooling, a drip edge that clears the siding, and a tall collar with a new storm collar and sealant around the flue pipe. Our chase cover replacement starts at $299 and comes with a free quote. If the framing underneath has rotted, a chase rebuild starts at $299. Sumner is about 35 minutes from our Renton office, and a cover swap can often be done the same day we look at it.

- 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
Sumner Conditions
Why this happens in Sumner
Prefab chimneys in Sumner's newer plats are exposed on the hillside above the valley, and they take the region's full 40.34 inches of annual rain by the Sea-Tac 1991-2020 normals. On a flat or dished galvanized cover, that water pools against the collar and the seams, and with measurable precipitation on roughly 150 to 156 days a year, the cover rarely dries before the next storm. Rust starts at the seams and works inward.
Inside the chase, the damage is slower but worse. Framing that gets wet in October stays wet through a winter where lows average 37 to 38F, and Western Washington's October-to-April moss season adds a green layer to any shaded cover and siding. A stainless cover installed before the fall rains keeps the framing dry and typically outlasts the rest of the chase.
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 Sumner — FAQ
Can you just patch the rust on my Sumner chase cover?
We can seal a small spot to get through a winter, but galvanized covers rust from the seams and the collar outward, and a patch on a cover that has already failed at one point is usually followed by a leak at another. A stainless replacement starting at $299 is the lasting fix, and the free quote covers both options.
How do you get the cover measurements on a Sumner home with a tall chase?
We measure from the roof during the free quote, including the chase dimensions, the flue pipe size and location, and the cap height. Many of the two-story homes east of SR 410 have chases that rise well above the roofline, and we bring the ladder and equipment for that. You do not need to go up yourself.
