Rust Stains on Your Chimney? Your Chase Cover is Failing.

If you see brown or orange streaks running down the sides of your chimney, your galvanized steel chase cover is rusting through. This is extremely common on prefab (factory-built) fireplaces throughout Chicago's suburbs — Schaumburg, Arlington Heights, Naperville, Orland Park, and beyond. The original builder used cheap galvanized metal that rusts within 10-15 years.

Chase Cover Replacement Cost

Stainless steel chase cover replacement runs $400–$800 depending on chimney size. Copper runs $600–$1,200. All our stainless steel covers include cross-breaks for water drainage, drip edges to prevent runoff staining, and new storm collars sealed with premium terpolymer sealant. Lifetime warranty on stainless steel.

Do not repair a rusted chase cover — replace it. Patching buys months, not years. A stainless steel replacement is a one-time fix that outlasts the chimney itself.

Frequently Asked Questions

How much does a chimney chase cover replacement cost?
Chase cover replacement in Chicago costs $300-$800 for standard sizes. Stainless steel covers (recommended) run $400-$800. Copper covers run $600-$1,200. The price depends on chimney size and accessibility.
How do I know if my chase cover is bad?
Rust stains running down the sides of your chimney are the #1 sign. Also look for: visible rust on the cover, dents or warping, water sounds inside the chimney, and water damage on walls near the fireplace.
What's the difference between a chimney cap and chase cover?
A chimney cap covers the flue opening (the hole where smoke exits). A chase cover covers the entire top of a framed/sided chimney chase (common on prefab fireplaces). Many prefab chimneys need both.
