Why have your flues swept?

Every fire and every bit of oil burned leaves soot in the flue. Without sweeping, it builds up until it becomes dangerous.

  1. 01

    Avoid a chimney fire

    Soot and tar deposits are flammable: they can catch fire and damage the flue, or even the roof.

  2. 02

    Proper smoke extraction

    A clogged or blocked flue (a nest, debris) draws smoke badly, with a risk of carbon monoxide coming back into the room.

  3. 03

    Stay covered

    If there's a claim, your insurer may ask for proof of a recent sweep. Keep the document we give you after the visit.

  4. 04

    A better draw

    A clean flue draws better: the fire lights more easily and your appliance burns more cleanly.

Which flues do we sweep?

  • Open fire and insert

    For wood fires used regularly, deposits build up quickly in the masonry or lined flue.

    • Mechanical sweeping of the flue
    • Visual check of the draw
    • Advice on use (dry wood, lighting)
  • Wood or pellet stove

    Stoves produce fine soot that quickly clogs the flue and the connecting pipe.

    • Sweeping of the flue and the connecting pipe
    • Check that the connection is sealed
  • Oil boiler flue

    Burning oil clogs the flue: regular sweeping is essential for the boiler to work properly.

Good to know

Gas boiler with a balanced flue?

Gas condensing boilers expel their fumes through a balanced flue or a dedicated flue. Their flue is checked during the boiler service, which is compulsory in the Brussels-Capital Region: as a rule, no separate sweep is needed.

Your project, step by step

How a chimney sweep works

  1. 01

    Appointment

    We set a slot, ideally before the heating season. Don't light a fire in the hours before: the flue must be cold.

  2. 02

    Protection

    The area around the appliance protected before starting.

  3. 03

    Sweeping

    A brush passed through the whole flue to loosen soot and deposits, then the residue removed.

  4. 04

    Check and advice

    The draw and the visible condition of the flue checked, advice on use and a job document to keep.

Frequently asked questions

Frequently asked questions about chimney sweeping

Can't find your question? Ask it on WhatsApp, with a photo if that helps, or leave your number and we'll call you back.

The obligations depend on your appliance and your fuel, and your insurer or your lease may also require it. In any case, sweeping at least once a year is strongly recommended for any flue used regularly.
