Chase cover replacement is the most common chimney job in DuPont: almost every home in Northwest Landing has a framed, sided chimney chase with a factory-built fireplace inside, and the cover the builder put on top was galvanized steel. On Hoffman Hill, Palisade and around Yehle Park you can spot the failures from the sidewalk: a rust streak down the siding from one corner of the chase. Inside, the signs are water or rust flakes on the firebox floor, a stained chase interior and a damp smell when the fireplace is cold. Left alone, the water soaks the plywood under the cover and the job grows from a cover to a cover plus framing.
We measure the chase, fabricate a stainless or heavy-gauge cover with a cross-break so water runs off instead of pooling, a drip edge that clears the siding, and a tight storm collar at the pipe, then install it and check the sheathing underneath while the top is open. DuPont chase cover replacement starts at $299 with a free quote, and a competitor's bid gets a free second opinion plus a price match and 10-25% off. DuPont is about 50 minutes from Renton, so we can often measure the same day. If you are not happy with the cover, we are not done.
Symptoms

- 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

- Visible rust holes or a sagging center in the metal lid
DuPont Conditions
Why this happens in DuPont
A flat galvanized pan in DuPont spends the wet half of the year full of water. Sea-Tac's 1991-2020 normals put annual precipitation at 40.34 inches, about 73 percent of it between October and March and only about 3 inches across June through August, so the cover ponds from fall through spring and dries only in summer, and the zinc coating wears through at the seams, screw heads and pipe collar where the water sits longest. The fir and cedar that line many Northwest Landing streets drop needles onto the cover, and that debris dams against the collar and keeps it wet even on dry days.
Once rust pits through, the framing below goes through the region's freeze-thaw cycle: around 60 days a year that touch 32F with winter lows averaging about 37F, so soaked chase sheathing freezes and thaws repeatedly and rots faster than it would in a colder, drier climate. Replacing the cover when the siding first streaks, typically well before water shows in the firebox, keeps a DuPont job small.
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 DuPont — FAQ
Half the houses on my DuPont street have rust streaks on the chimney chase. Is that a chase cover problem?
Almost always. Northwest Landing homes were typically built with the same galvanized cover, so they tend to fail around the same time and in the same spot, the seams and the pipe collar. We replace them with stainless starting at $299, and if you and your neighbors want to book together we can measure several on one visit and keep the per-home cost down.
I own a DuPont rental near JBLM. Can you replace the chase cover between tenants?
Yes. We coordinate access with your property manager or the outgoing tenant, measure on the first visit, install the fabricated stainless cover on the next, and send you photos of the old cover, the new one and the sheathing underneath. If the sheathing is soft we quote that separately for free. The cover itself starts at $299.
How soon can you do chimney chase cover replacement in DuPont?
We confirm a time by phone or text after you request a quote; same-day service is often available for urgent problems in DuPont and the rest of Pierce County.
