Capping two chimneys

I immediately noticed that my living room was staying warmer for longer, and I no longer get spots of mould in the recesses on either side of the chimney pot in the living room either. I’ve noticed my house get incrementally less damp with all of the small things I’ve been chipping away it on my journey to make my home warm, cosy and damp free, but capping the chimneys felt like a big improvement.
