Chase Cover Replacements
Long-lasting protection for your chimney chase.
The chase cover is a custom metal lid that seals the top of a chimney system, preventing water, debris, and animals from getting inside. While most often used on prefabricated and wood-framed chimneys, stainless steel chase covers are also a smart upgrade for some masonry chimneys, especially when crowns are deteriorated or beyond repair.
Unfortunately, many factory-installed chase covers are made from thin galvanized steel. These covers often rust, warp, or separate at the seams within a few years, leaving the chimney vulnerable to water intrusion. Once water enters the chase or masonry, it can cause staining, rusted components, interior leaks, and costly structural damage.
At Northwest Chimney, we replace failing covers with custom-fabricated stainless steel chase covers, built to last for decades without rust or corrosion.
Signs Your Chase Cover Needs Replacement
-
Rust streaks down the chimney chase or siding
-
Water stains or leaks inside near the fireplace
-
A warped, sagging, or deteriorated top
-
Visible corrosion holes or open seams
-
Pooling water on top of the cover
Why Stainless Steel?
Stainless steel chase covers are the industry standard for durability. Unlike galvanized steel, stainless steel will not rust through, ensuring reliable, long-term protection for your home.
Our covers are custom-fabricated for a perfect fit and feature:
-
Sloped design to shed water away from the chimney top
-
Cross-breaks (ridges) to prevent pooling
-
Fully welded seams for watertight durability
-
Optional powder coating for added style and protection
Chimney Caps + Chase Covers
-
For full protection, many chimneys need both:
-
A chase cover to seal the chimney top
-
A chimney cap to cover the flue opening and stop rain, downdrafts, and animals
We install both as part of a complete system designed to keep your chimney safe, dry, and efficient.
Why Replacement Matters
A failing chase cover is one of the leading causes of chimney leaks. Replacing it with a properly fabricated stainless steel cover prevents thousands of dollars in potential water damage, extends the life of your chimney system, and keeps your home safe.
Our certified technicians will evaluate your chimney system and recommend the right solution—whether a stainless steel chase cover, a rebuilt crown, or a combination with a chimney cap—for complete top-to-bottom protection. Schedule your chimney inspection today!
