What they do

Chimney Engineers/Technicians carry out installations and inspections of brick/masonry as well as metal flue systems.  They will work on both domestic and commercial projects.

  • Inspection of existing chimney and flue systems
  • Preparing and adhering to method statements for site works; including health and safety risk assessments
  • Repairing and renewing existing chimney and flue systems
  • Supervising assistant engineers ensuring that health and safety rules are adhered to
  • As much of a Chimney Technician’s work is carried out in people’s homes it is important that they have good communication skills and are polite and courteous at all times
