Do I have to remove my existing chimney pot to fit a Windkat Cowl?

Windkat is a chimney pot and cowl all in one so ideally your existing chimney pot should be removed. As we also offer Windkat with a plug-in configuration which can slide into a pot, there may also be the possibility of fitting Windkat on top of your existing pot, but particular attention must be paid to ensuring a firm, safe fit.
