Chimney Chase Cover

Custom Chase Covers for Prefabricated Chimneys in Greater Philadelphia & the Poconos

Prefabricated chimneys are vulnerable to water damage, especially if the top of the chase is left exposed or covered by a rusting metal lid. A properly fitted chimney chase cover protects your home by preventing rain, snow, debris, and animals from entering your chimney system. At Chimney Scientists, we specialize in custom stainless steel chase cover installation that’s engineered for long-term protection and designed to blend seamlessly with your home’s exterior.

We serve homeowners across Philadelphia, Montgomery, Bucks, Chester, Delaware, Lehigh, Monroe, and Carbon counties with high-quality materials, custom fabrication, and expert installation.

Keep Your Prefabricated Chimney Protected With a Quality Chase Cover

A chimney chase cover is the metal plate that sits on top of the wooden or metal-framed chimney chase on prefabricated chimney systems. Its job is similar to a chimney crown on a masonry chimney—it keeps water from entering the chimney system from above.

Many prefabricated chimneys are installed with stock galvanized metal chase covers, which tend to rust and deteriorate over time. If left unaddressed, a leaking chimney chase can cause water intrusion, rusted components, and internal rot.

How Do I Know If My Chase Cover Needs to Be Replaced?

There are a few key signs that your chase cover is failing:

  • Rust stains on the chase or siding
  • Water inside the firebox or stains on the ceiling near the chimney
  • A musty smell or dampness around the fireplace
  • Visible warping or sagging of the chase top

A rusted chimney chase cover is more than just an eyesore—it’s a warning sign that water is making its way inside your chimney system. Addressing it early can prevent costly damage and chimney repairs down the line.

Our Chimney Chase Cover Installation Process

Chase cover replacement typically requires two site visits by our trained technicians:

Day 1: Measurement & Fabrication

  • Two technicians access all four sides of your chimney to take 11 precise measurements.
  • We send those specs to our stainless steel chase cover manufacturer in New York.
  • Your custom chase cover is delivered to our facility in 5–8 business days, depending on seasonal demand.

Day 2: Installation

  • Our team safely removes the existing chase cover, storm collars, and chimney cap.
  • We inspect the underlying wood trim for rot and make repairs if needed—at no extra cost.
  • The new custom chase cover is installed, and all components are sealed and reassembled.
  • Your new cover is backed by a lifetime warranty and requires no ongoing maintenance.

What Makes Chase Covers So Expensive?

Customers often ask us why chimney chase cover replacement is more costly than installing a standard chimney cap. The answer comes down to four main reasons:

Customization

Unlike mass-produced chimney caps, every chase cover we install is fabricated specifically for your home. These covers are larger, heavier, and individually shipped, resulting in higher material and handling costs.

Two Visits, Two Technicians

Our process involves two on-site visits, with skilled labor and safe roof access required at each stage.

Manufacturing Hiccups

Custom fabrication occasionally runs into minor delays or adjustments, especially during busy seasons. We account for these in our scheduling and communication.

Unforeseen Issues

Once the old chase cover is removed, we may discover rotten trim or other water damage. We resolve these issues during the install, often at no additional cost to you, but they can increase the complexity of the job.

Frequently Asked Questions About Chimney Chase Covers

What’s the difference between a chimney cap and a chase cover?

A chimney chase cap fits over the flue pipe and prevents rain or animals from entering the vent. A chase cover is a large metal panel that covers the entire top of a chimney chase. They serve different purposes and are not interchangeable.

Are stainless steel chase covers worth it?

Yes. Stainless steel chimney chase covers won’t rust or corrode like galvanized metal, and they’re backed by lifetime warranties. They provide durable, long-term protection with no maintenance required.

How much does a custom chimney chase cover cost?

Pricing varies based on size, access, and whether trim repairs are needed. Our quotes include two technician visits, custom fabrication, and all necessary sealing and installation. After your initial inspection, we’ll provide a transparent estimate with no surprise fees.

We didn't know what was wrong with our chimney, but could see moisture was damaging the plaster in the ceiling around it. We consulted a roofer who said the issue was the flashing (on the roof just above the room where damage was visible). New flashing had absolutely no effect. Talked to another roofer who admitted he was stumped and recommended a company called "Chimney Scientists". Best recommendation EVER. The Chimney Scientist inspector recognized the problem immediately: unfortunate repairs in the 1980s to this chimney built in 1900 used a modern type of mortar (Portand cement) that trapped moisture inside our chimney, forcing water out through brick (and then into surrounding ceiling plaster). This past week Chimney Scientists rebuilt our chimney in the top floor of our house and up through the roof using historic lime-based mortar. They found reclaimed brick that closely matches our original brick for the exposed chimney inside the house. Above the roof, they used new brick that will resist the elements for a long, long time. End result: a gorgeous, healthy chimney inside and out. During the job, they provided thorough protection around their work area. At the end of the job, they cleaned up to perfection. All along the way, they cheerfully provided crystal clear and detailed explanations. Maybe best of all: they LISTEN. Whenever we had any concerns or questions, we were heard and any needed adjustments were made right away. The name Chimney Scientists isn't just great branding: these guys really DO understand the science behind chimneys and they take great pride in skillfully solving chimney problems. 10 stars out of 5.
