Chase Cover Installation

If you have a factory-built fireplace and chimney system, you should have a chase cover at the top of your chase, performing a function much like that of a chimney crown on a masonry chimney: protecting it against rain, snow, sleet, ice and other unfriendly elements.

The materials that a chase cover is made of will vary — you’ll routinely see galvanized metal, stainless steel and copper. Each material has its benefits, but we most often get calls about chase cover damage with galvanized metal products. The durability of galvanized metal chase covers can vary, but since that material is susceptible to rust and corrosion, it is possible to see problems in as few as five years.

Rust will probably give you the earliest indicator of a problem with your galvanized metal chase cover — streaks will form and run down the cover. This can happen because of the way it was installed (improper installation might let water pool on the cover, gradually corroding it; or holes from screws and nails could let water breach too). But those rust streaks are a big, colorful warning: Water is likely getting into your system, and that water could be causing damage to your fireplace and home.

Mason’s Chimney Service Can Help You Find The Right Replacement Chase Cover

If you need to have your chase cover replaced, Mason’s Chimney Service’s certified technicians can go over your different options, help you find the right product, and install it properly and efficiently.

Chase cover materials:

  • Galvanized metal – Particularly cost-conscious homeowners commonly choose galvanized metal, as it’s an affordable material. On average, you can expect a galvanized metal chase cover to last between five and 15 years before you’ll need to explore a replacement.
  • Stainless steel – We’re all well aware of the resilience of stainless steel — that’s why it’s such a popular material for everything from appliances to chimney flue liners. It’s more costly than galvanized metal, but it has some definite benefits — including the fact that it’s not susceptible to rust in the way galvanized metal is.
  • Copper – If looks and function are both at the top of your list, we love copper chase covers. Copper is a highly-durable material, and over time as a colorful patina develops, copper chase covers can add a striking look to your home.
