Having your chimney swept is a regulatory obligation, but it's also a safety issue. The point on what you need to know.
Chimney sweeping: a legal obligation
As soon as you have a chimney and use it, you must have it swept regularly (once or twice a year) to be in compliance with the RSDT (Departmental Health Regulations Type) of your place of residence. This even if your insurance company does not require it in your comprehensive home insurance contract. The law stipulates not only that the interior and exterior conduits must be kept swept regularly, but also that the sweeping must be carried out by a master chimney sweep. He will have to give you a chimney sweep certificate, to be kept preciously.
Chimney sweeping: safety and energy savings
By sweeping your chimney, you can get rid of soot, tar and ash which, when stuck in the flue, serve as insulation, reducing heat emissions and generating greater consumption of wood. Chimney sweeping is also a safety issue. It reduces the risk of poisoning but also the risk of fire. Finally, sweeping, by evacuating particles from the duct, participates in the fight against air pollution.
Chimney sweeping: from above or from below?
If both ways exist, today's chimney sweeps are equipped to work from below. They always use the famous hedgehog, a brush extended by several flexible poles (this allows to marry the angles of the conduit) which are screwed to each other until reaching the necessary length. The duct is cleaned by an energetic back and forth movement which makes it possible to take off the dirt starting from the bottom and going upwards. The chimney sweep - who took care to protect the floor and surrounding furniture - ends with a vacuum cleaner with a powerful device.
Chimney sweeping: practical info
A sweeping generally lasts half an hour and it takes 40 to 60 euros (price generally charged for the chimney of a house). Have your chimney swept preferably in the spring when you stop making a fire. By taking it in the fall, you risk having a long waiting period.
