Mercer Island has been rebuilding itself lot by lot for decades, and most houses built or rebuilt since the 1980s have a factory-built fireplace inside a framed, sided chase rather than a brick chimney. The metal lid on top of that chase is the chase cover, and the builder-grade galvanized ones rust through in the lake air. The first sign is usually a rust streak down the siding on a West Mercer Way or East Mercer Way chase, then a drip inside the fireplace, then soft drywall on the chase wall.
We replace chase covers starting at $299. We measure the chase, fabricate a stainless steel cover with a raised center so water runs off instead of pooling, a turned-down skirt over the siding, and a collar sealed around the pipe, then install it and check the cap and storm collar while we are up there. The quote is free, we price match and take 10 to 25 percent off a competing bid, and Mercer Island is about 20 minutes from our Renton office via I-90, so same-day replacement is often possible. If you are not happy, we are not done.
Symptoms
Signs Mercer Island homeowners notice

- Standing water or rust pooling on top of the chimney after rain
- Water dripping onto the fireplace or staining the ceiling beside it
- 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
Mercer Island Conditions
Why this happens in Mercer Island
Chase covers on the island fail faster than the ones in drier suburbs because they never dry out. The wet season from October through March delivers about 29.65 inches of the year's 40.34, and a flat galvanized cover holds a puddle after every storm. On the west shore the puddle gets refilled by wind-driven rain off the lake, and on shaded lots below Island Crest Way and around Pioneer Park the cover sits under a drip line from the trees for months.
Freezing nights finish the job. Mercer Island sees about 60 days a year that touch 32F, and when the water on a sagging cover freezes it pushes at the seams and the screw holes, so by the next thaw the cover leaks where it did not before. A stainless cover with a crown in the middle does not pool, does not rust, and does not need to be replaced again, which on an island lot with a tall chase is worth a lot.
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 Mercer Island — FAQ
How do I know my Mercer Island chase cover needs replacing and not just sealing?
Rust streaks on the siding, a dip in the middle of the cover, or water in the firebox after a storm all mean the metal has failed and sealant is a short-term patch. We take a look as part of the free quote and show you photos. Replacement starts at $299 and the stainless cover does not rust again.
Can you replace the chase cover on a tall lakefront chase on Mercer Island?
Yes. Waterfront rebuilds on the island often have two- and three-story chases on a steep lot. We bring the ladders and fall protection the height calls for, measure on the first visit, fabricate the stainless cover, and install it on the second visit, usually within a few days. You do not need to be on the roof at any point.
How soon can you do chimney chase cover replacement in Mercer Island?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Mercer Island and the rest of King County.
