A chimney cap costs about $300 to install or repair, with a typical range between $75 and $1,000. But the price will fluctuate based on the type of repair, the material used, and the dimensions of the chimney cap. Despite being simple in nature, a chimney cap is one of the most integral parts of the chimney system. They help keep debris and wild animals out of the chimney, allowing your fireplace to run safely.

How Much Is a Chimney Cap?

You can select from three types of chimney cap materials—galvanized steel, stainless steel, and copper.

Galvanized Steel

Galvanized steel has the lowest durability out of the three, but also comes with the lowest cost. A galvanized steel chimney cap will cost anywhere from $15 to $200, depending on the gauge of the steel and the size.

Stainless Steel

Stainless steel chimney caps are the next level up when it comes to strength and durability. These chimney caps usually last longer than their galvanized counterparts. Expect to pay around $50 to $500 for a stainless steel chimney cap.


Copper is considered the top tier of chimney caps. This type of cap has one of the most pleasant aesthetics while also standing up to debris, rain, snow, and critters. When shopping for a copper chimney cap, expect to pay around $150 to $900, depending on size and shape.

Chimney Cap Repair or Replacement Cost

Realistically, a broken or damaged chimney cap often isn’t worth it to repair. The price of materials needed and labor typically comes out to be the same price as replacing it, putting the price for both repair and replacement at around $350.

Chimney Cap Installation Costs

Beyond material and type of repair, a few details go into the chimney cap replacement process. You should think about cleaning the area before work begins and consider whether you want a custom cap or a prefabricated option.


Typically, labor makes up about 50% of the project's total cost. However, it's likely to take up more, as most homeowners often buy the chimney cap separately before a chimney repair company installs it.

Custom vs. Prefabricated Chimney Caps

Custom chimney caps have gained popularity in recent years. They allow you to choose more stylish options that wouldn’t necessarily be available from prefabricated options.

Custom chimney caps can range anywhere from $200 to $1,000, depending on the shape, colors, and type of material requested.

Prep Work

You should ideally have a clear spot for the chimney cap to go. Your best bet is to hire a chimney sweep to handle the job. Chimney sweeps cost anywhere from $130 to $380—and you can also ask if they install chimney caps.

How Much Does a Chimney Cap Cost to Replace or Repair Yourself?

If you’re familiar with a toolbox and you have a relatively flat roof (a pitch of 4/12 or under), you should be good to install the chimney cap yourself. In addition to the chimney cap of your choice, you'll need a ladder and a screwdriver. You'll save around $150 to DIY.

You may consider sealing your chimney while you’re installing the cap. The cost of sealing and capping a chimney is around $575 on average.

Remember, any time you're up on a ladder or your roof, you're taking some risk. That's why it may be better to call a professional to handle the job. But if you’re planning to replace or repair a chimney cap yourself, it’s wise to familiarize yourself with all the important parts of a chimney, which are illustrated below.

Frequently Asked Questions

A chimney cap is necessary to keep your fireplace running smoothly—and your home safe. One of the main reasons to install a chimney cap is that it helps keep away wild animals such as birds and squirrels, but it also serves as protection from debris entering the rest of the system.
