Tukwila splits neatly into two kinds of chimney. Up on Tukwila Hill and through Foster, Riverton and McMicken Heights, the 1950s-70s ramblers and split-levels mostly carry brick. Down on the Green River valley flats around Southcenter, Baker Boulevard and the newer townhome rows near Tukwila Station, the fireplaces are factory-built units inside a siding-clad wood chase, and the only thing between the framing and the weather is a sheet of galvanized steel on top. Water ponds against the storm collar, the screw holes rust open, the seams split, and the first sign most owners notice is an orange stain bleeding down the siding or a soft spot in the ceiling next to the firebox.
Our fix is a cover cut to your chase's exact dimensions, cross-broken so water sheds to all four edges, with a raised collar and a drip edge that clears the siding. Chase covers start at $299 and the quote is free; bring us a written bid and we will price match plus 10-25% off. Tukwila is about 10 minutes from our North Renton office via I-405 or Interurban Avenue, so a common size can usually be measured, fabricated and installed the same day. When the plywood under the old cover has gone soft, we photograph it and quote a chase rebuild alongside the cover.

Tukwila Conditions
Why this happens in Tukwila
The valley floor changes the math on a flat cover. Sea-Tac's 1991-2020 normals, recorded just west of the city, put annual rain at 40.34 inches, with about 29.65 inches falling between October and March and November alone at 6.31 inches. A cover with even a shallow dish holds that water for months, and galvanized steel fails first where water sits: the fastener holes and the folded corners. Roughly 60 nights a year touch freezing, and each one expands the water lodged in those seams.
Shade finishes what the rain starts. Western Washington moss spreads fastest from October through April on north-facing and tree-shaded surfaces, according to regional roofing guidance, and the chases tucked behind a townhome row near the Green River Trail or under the firs along Tukwila Hill get exactly that exposure. Once moss and needles dam the cover's edge, the water has nowhere to go, the rust races ahead, and the framing underneath may not dry out until July.
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 Tukwila — FAQ
What are the signs that my Tukwila chase cover needs replacing?
Look for rust-colored streaks on the siding just below the top of the chase, a brown ring or peeling paint on the ceiling beside the fireplace, a damp smell in the room above, or a visible dip if the top is in view from an upstairs window. We check it from our own ladder and give you photos with a free quote.
Our Southcenter-area HOA has a whole row of chases. Can you handle them together?
Yes. Townhome rows on the valley floor were usually built with identical chases, so we measure the whole row in one visit, fabricate matching cross-broken covers, and hand the board or property manager one written quote with photos of each unit. Being 10 minutes away via I-405, we can split the work around residents' schedules without dragging it out.
How soon can you do chimney chase cover replacement in Tukwila?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in Tukwila and the rest of King County.
