How to Prevent Chimney Rust in Central PA

Many homeowners don't realize that chimney rust can be a serious issue on their property, but it is. Your chimney is exposed to all the weather central PA experiences, and over time, moisture from rain and snow can cause rust. Chimney rust can eventually cause damage to your chimney and may require repair.

Anderson's Chimney & Masonry Services has put together this guide to help you understand what this common problem is and how to prevent chimney rust at your central Pennsylvania home.

What Is Chimney Rust and What Causes It?

Chimney rust is comprised of iron oxide, a material formed by a reaction of oxygen and iron. You may have seen rust form on metal objects left outside. Similarly, the metal parts of your chimney, such as the damper, chase cover or flue liner, can start to rust because they're metal parts exposed to the elements.

When this happens, the rust eventually spreads to the chimney, where it can cause damage. If you notice signs of rust, it's time to call in the professionals at Anderson's Chimney & Masonry Services.

Signs of Rust

The most obvious sign of rust is reddish-brown stains on the bricks, masonry or the surrounding metal components of your chimney, such as the chimney cap. You may notice also rust in the firebox, on the flashing or on the exterior of your chimney. You may eventually notice parts of your chimney crumbling, too.

If you suspect any rust, it's best to call in the professionals. Rust can cause parts of your chimney to deteriorate, which can cause water to enter your home and cause damage. If your flue liner becomes damaged, it'll be unsafe to use your fireplace.

How to Prevent Chimney Rust in Central PA

Preventing chimney rust in central PA comes down to a few best practices:

  • Install rust-resistant chimney components: If you install stainless steel liners, chimney caps, chase covers and flashing, these components won't rust, even when exposed to central PA weather. This can extend the life of these components and the life of your chimney. Although there are other rust-resistant materials, stainless steel contains chromium, a durable material that provides excellent protection against water and oxygen. This is more effective than materials treated with zinc or another “rust protection” coating.
  • Schedule yearly maintenance: Regular maintenance of your chimney means a professional will look closely for any signs of rust and other damage, which can help you avoid more expensive repairs later. Inspectors can look for rust and any signs of pests or other damage, so they can conduct repairs before the chimney deteriorates further.
  • Check regularly for holes: Holes that allow water into your chimney or chimney components can lead to rust or other damage. Get into the habit of checking for damage regularly, especially after storms, and get it repaired promptly. You can close small holes with a waterproof sealant, for example, to prevent rust.
