 What Is a Chimney Chase Cover?

 What Is a Chimney Chase Cover?

A chimney chase cover is the metal panel that covers the top of a framed chimney chase (common in newer homes with prefab fireplaces). Unlike masonry crowns, chase covers are made of sheet metal and often include pre-cut holes for flue pipes and spark guards.

It’s often mistaken for a chimney cap, but both serve different purposes.

Typically made of galvanized steel, stainless steel, or aluminum

Designed to shed water and protect chimney components

Works alongside chimney caps to keep flue protected

Custom-fitted for rectangular, square, or round chases

Prevents rust, water leaks, and nesting animals

Signs You Need a Chase Cover Replacement

Signs You Need a Chase Cover Replacement

Because chase covers are out of sight, damage often goes unnoticed until leaks occur. Routine inspection of the top of your chimney structure can help spot early signs of failure.

Rust or staining on the chase, water dripping in the firebox, or musty smells are all red flags.

Visible rust or discoloration on cover edges

Water spots inside firebox or around ceiling

Warping or sagging in the middle of the cover

Pooled water on top due to poor slope

Gaps, separation, or visible holes around the flue pipe

Chase Cover Materials: What’s Best?

Chase Cover Materials: What’s Best?

Chase covers come in different materials, each with its pros and cons. The cheapest options are more likely to rust or fail quickly, while higher-end materials offer better longevity and warranties.

Stainless steel is the gold standard for durability and resistance to rust.

Galvanized steel: inexpensive but prone to rust (5–10 years lifespan)

Aluminum: rust-resistant, lightweight, less durable than steel

Stainless steel: rustproof, long-lasting, ideal for all climates

Copper: premium appearance and durability, but high cost

Always choose a sloped design to prevent standing water

Chase Cover Replacement Process

The job typically takes 1–2 hours and is often paired with chimney cap installation.

Full inspection of chase and flue collar

Removal of old or rusted cover

Cleaning and prep of chase top

Installation of new sloped stainless steel cover

Sealing around all flue pipe openings

Frequently Asked Questions about Chase Cover Replacement

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

A chimney cap covers the flue pipe only, while a chase cover seals the entire top of a chimney chase box.

 How much does a chase cover replacement cost?

Most replacements cost between $300–$700, depending on size, material, and installation access.

How long do stainless steel chase covers last?

Stainless steel covers can last 20+ years with little to no maintenance and often come with lifetime warranties.

Can I replace a chimney chase cover myself?

It’s not recommended. Improper installation can lead to leaks and safety issues. Hire a chimney professional for best results.

What happens if I don’t replace a damaged chase cover?

Water will eventually seep into the chimney structure, leading to wood rot, rusted fireboxes, mold, and costly repairs.

These guys are pros.The people in the office pick up the phone (unlike many other contractors) and are straightforward and friendly. The crew explained my options and were very clear about everything they were doing. The boss (over the phone) cleared up any issues I had and did everything to have me as a happy customer. The chimney cap looks perfect and the upgraded water heater and boiler lines look great.Great quotes, great price, great work, friendly people.I wonder if they do other work besides chimneys?

How we work:

Step#1
Contact us
You're not sure if you need chimney services, or what to expect if you do. It's normal to have a lot of questions about chimney services- after all, it's not a service that most people need on a regular basis. That's why we offer free estimates and consultations so that you can get all your questions answered before moving forward with any work. We understand that your satisfaction is our number one priority, which is why we work hard to provide quality chimney services that meet your needs and expectations. We want to make the process as easy as possible for you, from start to finish!
Step#2
Proposal
You have a problem that needs to be fixed but you're not sure how or where to start. It can be tough to know where to start when it comes to fixing a problem, especially if you're not familiar with the topic. We're here to help. We'll do a full evaluation of what needs done and how it can be accomplished. We'll give you our proposal including plans, timelines for completion as well as the guarantee that if any issues arise during this process we have an answer or solution at hand!

It's stressful to have people in and out of your house all the time. And it's even more stressful when you're not sure what they're doing or when they're going to be done.  It's hard enough keeping your sanity with construction going on day and night, but then to have to worry about the clean-up crew coming? Ugh. We take care of everything for you so that you can relax and enjoy your new space without any stress. You don't have to lift a finger except to tell us what you want. We'll work around your schedule, do all the dirty work, and leave your home just as clean (or cleaner) than when we found it.
