Chimney Crown Repair and New Flue Cap

One of the items during the initial inspection was a minor repair to the Chimney. Mainly, the crown was in need of resurfacing / repair and the two flue caps had holes in them from years of service.

Old rusted and failing chimney caps made of steal

Like many of my projects, if I can spend just a little more to get the next level of quality that is my primary objective. Something a little nicer.

Instead of purchasing two black painted steal replacements, I found a stainless steal unit that I have seen on more high-end houses in our area. They just look nicer and of course stainless steal won’t rust out. In order to archive the look I was shooting for, I wanted to find, if possible a single unit that could span across both flues. The largest of the two measured 13×13 and the smaller flue was 10×10. The length was 38 inches from the outside end to the outside of the other flue. I lucked out and found a 13×49 inch “The Forever Cap Multi Flue Stainless Steel Crown Mount Chimney Cap” This allowed for me to center the stainless flue cap on the entire chimney.

All assembled and ready for the next step – Replacing a Dual Flu Cap with a Stainless Steal unit.

My oldest daughter was brave enough to help out on this project. She has never been on the roof but we figured out she was not afraid of heights. So up to the roof we went. As you can see below the crow was really in need of repair. Don’t forget you will need a pair of pliars or channel locks to remove the old caps!

Chimney Crown needing repair

I purchased a tool and the crown repair paint. It is very thick paint that seems to be half cement and half latex paint. The brand is Chimney RX – Brush-able Crown Repair. An EXCELLENT product.

Repairing your Crown is as easy as two simple steps… clean with a BBQ brush and then paint.

Here are the simple steps to prep the surface for the new coat of paint. Keep in mind they don’t recommend using the product to repair deep cracks. If you need to repair the concrete then you will need in addition to buy some concrete repair.

  1. Get a BBQ Brush with a scraping head. You can find these at the dollar store or here on Amazon.
  2. Remove (if you have them) the old chimney caps. If you will discard them and not reuse just chuck them down to the ground to get them out of the way.
  3. Now take out the BBQ brush and start to brush the crown from end to end.
  4. Use the scraper to remove old semi loose concrete and in my case the old paint.
  5. Blow off the remaining dust and dirt once you have ran the scraper.
  6. Get a decent pain brush. It does not need to be a fancy high end brush but something that is clean and has good bristles.
  7. Now open the container of Chimney RX – Brushable Crown Repair. find a central spot and slowly pour the paint onto the crown. Start with a little and work the paint into the crown. Keep in mind it is very thick but goes on easily. Use long even strokes and it will look like new concrete when done!
  8. Make sure to pay attention to the ends so you don’t paint the side of the chimney.
  9. Now let it dry thoroughly. It says cure time is roughly 4-6 hours but I needed to let it sit for a little more than a day.
  10. Get your The Forever Cap Multi Flue Stainless Steel Crown Mount Chimney Cap There are multiple sizes from this company, Made in the USA and high quality.

Once the Crown repair dried over night, we were ready to mount the stainless cap.

You will need a drill and a set of cement anchor screws. A screw driver and or a socket set to secure the anchors properly. Once done, you will be very happy with the results. I know I am.. total time (outside of drying time) was roughly 1.5 hours. I still need to get the front side screws drilled and tightened, mainly due to the crown not being 100% dry. A relatively simple job that will last for years to come.

Until next time!
