Chimney cap installation may seem like a task you can’t tackle, but if you plan accordingly you will see you can. One of the items during the initial inspection of our house was a repair to the Chimney Cap and Crown. In the previous post, I talked about repairing the chimney crown using a product called Chimney RX Crown Repair. An excellent product that is working out great . The crown is the top of the chimney that typically has concrete as the main surface and where the flu exit is. Today we are going to talk about the Chimney Cap. One thing to note on this “Do it yourself”, like many of my projects are easy enough that anyone with basic skills can do. My only caution is if you don’t like heights and don’t like ladders, this project may not be for you. Hire a professional or bribe a friend or sibling.
Chimney Cap Installation – Finding the Right One
Instead of replacing the old black painted steal units (2), I found a full width stainless steal unit that I have seen on houses in our area. In my opinion, they just look nicer. Stainless steal won’t rust out for generations and resist moss and other organic growth on them. In order to archive the look I was shooting for, I wanted to find a single unit that could span across both flues and over the majority of the brick.
The largest of the two flues measured 13×13 and the smaller flu was 10×10. The length was 38 inches from the outside end to the outside of the other flu. I lucked out and found a 13×49 inch “The Forever Cap Multi Flu Stainless Steel Crown Mount Chimney Cap” This allowed for me to center the stainless flu cap on the entire chimney. Our flues were NOT centered so in order to make it somewhat symmetrical I needed a larger cap. SOME companies (as in the video below) recommend an entire cap of the Crown. However in my case that would look rather odd as it would have to be huge.
When we got the cap, it was easy to assemble and it literally took 5 minutes from the box, to reading the instructions and fitting it together. There was one small bend that I needed a hammer to tweak one of the tabs but no big deal at all. just assemble the pieces and use a 10 MM ratchet to tighten down 4 nuts.

As I stated earlier the crown was in desperate need of repair. We took care of that part in no time.

Steps to Replace Your Chimney Cap
What you will need
Order and assemble your chimney cap
Align Cap
Drill Holes
Secure Bolts

Once done, you will be very happy with the results. This cleaned up the appearance of our home as the old ones were unsightly Now it looks much better when you pull into our carport. Not only did it not look nice it was actually leaking water down the chimney. One year later, it still looks nice and you really can’t tell the difference (still looks like new).
A relatively simple job that will last for years to come.
