A chimney chase cover is a cap that seals off the top of a wood framed or brick laid chimney chase. Chimney chase covers are typically made from low grade steel, which will rust over a short period of time. The smallest gap or hole on the chase cover can lead to expensive water damage. If you're noticing a leak or rust stains down the side of your chimney, it is time to replace the rusted cover with a stainless steel cover. Stainless steel covers will never rust, so this will be a one-time fix.

Step 1: Getting Started

The tools that are needed to successfully replace your chimney chase cover are the following: hammer, flat or Phillips head screw driver, drill, steel cutting drill bit, razor knife, caulk gun, and 1 tube of weather proof silicone.  Take a look at this measuring guide to help you measure the chimney chase cover correctly.    http://www.rockfordchimneysupply.com/chase-covers.php?holes=1O#chaseform

Step 2: Removing the Rain Cap

Start by using your flat or phillips head screw driver and remove the rain cap from the vent pipe. There are generally 3 screws located on the side of the rain cap. Make sure you save the screws so you can reuse them to put the rain cap back on.

Step 3: Remove the Storm Collar

Use your razor knife and cut the silicone away from the collar and the vent pipe. If the storm collar shows no sign of rust, hold on to it and reuse it.

Step 4: Remove the Rusted Chase Cover

Using your hammer, remove the nails from the sides of the chase cover. Sometimes you will find nails on the top of the cover. Once you remove the nails, take the rusted cover off of the chimney.

Step 5: New Chimney Chase Cover
