A professional chimney chase cover service is essential for protecting your chimney and home from water damage. The chase cover sits on top of a prefabricated or factory-built chimney chase and acts as a barrier against rain, debris, and pests. When the cover becomes rusted, cracked, warped, or improperly fitted, moisture can enter the chimney system and cause serious damage.

Our professional chimney chase cover service includes inspection, repair, and replacement of damaged or worn chase covers. A properly installed chase cover helps prevent leaks, rust, mold growth, wood rot, and deterioration inside the chimney structure. It also helps extend the life of your chimney and fireplace system.

Many standard chase covers are made from thin metal that can rust over time. Upgrading to a custom stainless steel chase cover provides stronger, longer-lasting protection and better performance in all weather conditions.

If you notice water stains near the fireplace, rust around the chimney, or signs of leaks after rain, your chase cover may be the problem. Trust experienced professionals to install a durable chimney chase cover that keeps your chimney sealed and protected for years to come.

What is a Chimney Chase Cover?

A chimney chase is a framed structure, often made of wood, that houses the metal flue pipes for a manufactured fireplace. The chimney chase cover is a custom-made metal top that fits over the entire opening of this structure, similar to how a shoebox lid fits a box. Its primary job is to create a watertight seal and prevent anything—from rain and snow to debris and wildlife—from getting inside the chase.

It’s easy to confuse a chase cover with a chimney cap. A chimney cap is the smaller, protective covering that sits directly on top of the flue pipe, while a chase cover protects the entire chase structure. In a traditional masonry chimney, the concrete crown serves a similar purpose to a chase cover.

Common Signs of a Failing Chase Cover

Because it’s constantly exposed to the elements, a chase cover can deteriorate over time. Be on the lookout for these red flags:

• Rust Stains: This is the most common sign of a failing galvanized steel chase cover. If you see rust on the cover itself or rust-colored streaks running down the siding of your chimney, it’s a clear indication that the cover is corroding and needs to be replaced.
• Pooling Water: A properly designed chase cover should have a slight slope or “cross-breaks”—diagonal creases—to direct water off the surface. If you see water pooling on top, it can accelerate rust and lead to a compromised seal.
• Leaks or Water Damage: Any sign of a leak, such as water stains on the ceiling or walls near the chimney, is a serious sign that your chase cover has failed and is allowing water into your home’s structure.
• Dents or Warping: Severe weather, hail, or a falling tree branch can dent or warp the cover, compromising its ability to protect the chase.
