Now it was the time to take care of the chimney. I have an old very old house and I didn't want to spend too much on a chimney cap. This is not a cheap quality product or a high end product either. It is something in the middle. As soon as we attached without issues to the chimney I'm confident It will last for a few years to come. There right size for our chimney is 9.5x9.5 since this size is not standard, we had to keep it higher than expected. It's secure and I hope we don't have to do readjustments.
