Seattle's post-2000 infill boom built thousands of townhomes and new single-family homes with factory-built fireplaces, and nearly all of them vent through a framed, sided chase topped by a sheet-metal chase cover. Many of those covers were galvanized steel, and in Seattle's climate galvanized steel typically starts rusting through in well under the life of the house. The first sign is orange streaks down the siding below the chimney. The next is water in the firebox or a stain on the ceiling next to the chase, because once the cover pits through, rain drops straight into the wood framing.
We measure the chase, fabricate a stainless steel replacement cover with a cross-break so water sheds instead of pooling, a proper drip edge, and a sealed storm collar at the flue pipe, and install it in a single visit. Chase cover replacement starts at $299. The quote is free, and we price match plus 10-25% off any written quote you already have. Our Renton office is about 20 minutes from most Seattle neighborhoods, so same-day service is often available. If you're not happy, we're not done.
Symptoms
Signs Seattle homeowners notice
- Rust-colored streaks down the siding below the top of the chimney
- 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
Seattle Conditions
Why this happens in Seattle
A chase cover is a flat metal pan, and Seattle gives it 40.34 inches of rain a year to hold. Covers that were installed flat, without a cross-break, typically pool water in the center, and a pool that sits through a Seattle November (6.31 inches on average, the wettest month) finds every pinhole and seam. Galvanized covers corrode from those pools outward. We see the same failure on Seattle townhome rows built in the same year by the same builder: one cover rusts through, and the neighbors' covers are usually close behind.
Shade accelerates it. Western Washington moss and debris spread fastest October through April on shaded surfaces, and a chase cover under a neighbor's tree in a dense Seattle infill block collects needles that trap moisture against the metal. Stainless steel does not rust from that exposure the way galvanized does, which is why we replace with stainless rather than patching the original.
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 Seattle — FAQ
I live in a Seattle townhome row. Can you replace just my chase cover, or does the whole building need to be done?
We can replace just yours. Each unit's chimney chase typically has its own cover, and we fabricate it to your chase's exact dimensions. That said, if your cover has rusted through, your neighbors' covers from the same build are usually in similar shape, and we are happy to quote several units in one visit, which often lowers the per-unit cost. Starting at $299, free quote.
How do I know the leak is the chase cover and not the roof around my Seattle chimney?
Rust streaks on the siding below the chimney top, water in the firebox, or a stain on the ceiling right beside the chase all point to the cover. A roof leak typically stains away from the chimney. We inspect the cover, the storm collar, the flue cap, and the chase siding before quoting, so you get the actual cause. The inspection and quote are free, and same-day is often available.
How soon can you do chimney chase cover replacement in Seattle?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Seattle and the rest of King County.
