Not every Lynnwood chimney is brick. Homes built in the 1980s, along with much of the condo and townhome stock around Alderwood, typically use a factory-built fireplace with a metal flue running up through a framed, sided chase. The metal sheet on top of that chase is the chase cover, and the original builder-grade ones are thin galvanized steel that rust from the inside out. The first sign is usually rust streaks down the siding; by then the pan is often perforated, and rain is dropping onto the firebox top, the framing, or the ceiling drywall below.
We replace chase covers starting at $299, measuring the chase on site so the new cover has a proper drip edge, a cross-break so water runs off instead of pooling, and a collar that fits the flue pipe. Stainless is the longer-lasting option; we'll quote both. Lynnwood is about 40 minutes from our Renton office, and we cover Alderwood Manor, Martha Lake, Lake Stickney and Brier on the same runs. Start with a free quote; if you have a bid from someone else, we'll price match plus 10-25% off on a free 2nd-opinion quote. If you're not happy, we're not done.

Lynnwood Conditions
Why this happens in Lynnwood
A chase cover is a flat metal pan sitting in Lynnwood weather for about 150-156 rainy days a year, with 40.34 inches of rain annually at Sea-Tac's long-term normals. Builder-grade galvanized covers are typically installed flat, without a cross-break, so water pools around the flue collar and at the screw heads instead of draining. Standing water is what eats through galvanized coating, and once it's through, every storm from October to March, which is about 73% of the year's rain, is going into the chase. Because the chase is framed wood with siding, a leaking cover does more damage per dollar than almost any other chimney problem: wet sheathing, stained ceilings, and a rusted firebox top on the factory-built unit below. The fix is simple and inexpensive relative to what it prevents, which is why we push Lynnwood homeowners with 1980s prefab chimneys to have the cover looked at before the wet season rather than after a stain shows up.
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 Lynnwood — FAQ
How do I know if my Lynnwood chimney has a chase cover or a crown?
If the chimney is sided to match the house and has a round metal pipe and cap on top, it's a framed chase with a chase cover. If it's brick with a flat concrete top, that's a crown. Plenty of 1980s Lynnwood homes have the sided kind. Send us a photo from the yard and we'll tell you which, free.
Does replacing a chase cover need HOA approval in a Lynnwood condo?
Often the chase and roof are common elements, so the HOA may need to approve or may be responsible for the cost. We'll give you a written free quote with photos you can forward to the association, and we can coordinate with their property manager on scheduling if they want the work done through us.
