Renton has more prefab chimneys than brick ones, because the city's median home was built in 1988 and most of the big annexation-era plats in Benson, Cascade, Fairwood and the East Renton Highlands went up in the 1990s and 2000s. Those houses have a wood-framed chase sided to match the house, with a factory-built fireplace inside and a sheet-metal cover on top. The original covers were typically flat galvanized steel, and after two or three decades of rain they rust at the seams and screw holes, sag into a puddle around the flue collar, and start sending rust streaks down the siding. Left alone, the water goes into the chase framing and the ceiling below.
We replace the cover with one measured to your chase, cross-broken so water runs to the edges, with a tall collar at the flue pipe and a drip edge that kicks water out past the siding. Chase covers start at $299, the quote is free, and because our office is at 1202 N 10th Pl Unit 1509 in downtown Renton we can usually measure and install within days. If the plywood under the old cover is soft, we will show you and quote a chase rebuild, which starts at $299. If you have another bid, we price match it and take 10-25% off.

Renton Conditions
Why this happens in Renton
A chase cover in Renton is a flat steel sheet sitting under 40.34 inches of rain a year, the Sea-Tac 1991-2020 normal, spread over roughly 150-156 days. November alone averages 6.31 inches. Any slight sag turns the cover into a shallow pan that holds water through most of the wet season, and standing water is what eats through galvanized steel at the seams and fastener holes. A cover installed when a Fairwood house was built in the 1990s has now been through roughly 30 of those wet seasons.
Renton's tree cover makes it worse. The plats in Fairwood, Cascade and the East Renton Highlands were cut into fir stands, and regional roofing guidance is consistent that Western Washington moss spreads fastest October through April on north-facing or tree-shaded surfaces that dry slowly. Moss and needles on a chase cover block the drainage path, so the puddle lasts longer and rust starts sooner. Once water is past the cover, the chase framing typically stays wet all winter, and that is where the costly damage happens.
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 Renton — FAQ
How do I know if the chase cover on my Renton house is the problem?
Rust streaks on the siding right below the top of the chase are the classic sign. Others are a brown stain on the ceiling near the fireplace, a musty smell in the room above, or visible sag and standing water if you can see the top from an upstairs window. Any of those is worth a free quote; we check the cover and the framing under it.
Can you replace a chase cover in a Renton townhome or HOA neighborhood?
Yes. Many Benson and Fairwood townhome rows have identical chases, and we can quote one or the whole row. For HOA approval we provide a written quote with photos and the cover specification so the board can sign off without another site visit.
How soon can you do chimney chase cover replacement in Renton?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Renton and the rest of King County.
