i think you will find that a lot of people in the USA & Canada sweep there own flues, some of the videos on RU-vid are horrendous, no PPE worn and no sheeting up either, and it always appears to be about saving money, 🤨 the only people I've met who sweep there own are canal boaters, they use the very old fashioned toilet brush 😝, although I did sweep a boat chimney due to the creosote build up, due to the ill effects it had on the owner, Martin from NACS has asked me to do a write for the magazine, 🤓
