This launch guide maps the topic, the source base and the practical questions. Check the linked official authority before acting on a rule, deadline, price or safety requirement.
What this guide covers
Sweeping is legally required in both countries and the rules are genuinely confusing: how often for a permanently occupied house, a summer cottage, a sauna stove, a flat with an open fireplace, and a pellet or oil boiler; who may do it, what a sweeping certificate is, when you may sweep yourself and when only a certified sweep counts, what it costs, and what happens to insurance after a chimney fire without one.
Plus a page per fault: poor draught and its causes, smoke pushing back into the room, tar and creosote, a cracked flue, a shared flue in an old apartment block, a stainless liner, terminal height above a roof, and what a chimney fire looks like and does.
How to use it
Use Chimneys, flues and sweeping to understand the inputs, units and assumptions before relying on an output. A useful result should be reproducible from the named source rather than presented as an unexplained score.
The page keeps the main question, its evidence base and its limits together in one canonical place. That makes it useful as a quick orientation and avoids splitting a broad subject into shallow pages before each narrower answer has enough verified material of its own.
