I am a Certified Chimney Sweep. I love my job. While the traditional thoughts of chimney sweeps doing something dirty and dangerous for a quick buck still are partially true it's a bit more interesting than the title implies. Especially because I am a business owner.
We sweep chimneys, provide inspection reports for home buyers, insurance agents, and on occasion provide expert testimony on cause and origin related to solid fuel chimneys and structural fires. Most chimney sweeps also, repair and replace systems. We reline chimneys, install new stoves and inserts, and when things are slow tackle a tuck-pointing job or two.
While basic familiarity, knowledge, and certification can be obtained in a few months, an apprenticeship is desirable for comprehensive reports. Certification with the Chimney Saftey Institute require ongoing CEUs. I also have three additional certifications from the National Fireplace Institute.
Positives
Won't be "outsourced"
Allows flexibility in hrs
Decent wages
Interesting - you never know if the next job will be at a ten million $ mansion or a humble apartment.
Variety - from physical labor to sales and technical condition reports
Negatives
EPA is tightening regs
Dirty - not like you think, but one must willing to do whatever it takes...
Seasonal - this used to be a big one - income fluctuates because of the "silly season" Sept. 1st through Jan 1st. I have adapted my budget through the years to make this work. Also, having a rather large client base and offering repeat discounts has helped equalize the calls in spring and Summer.
Litigious - The fact is, chimney fires are a leading cause of structural fires and carbon monoxide poisoning kills people. At fault or not the attorneys tend to look for the last guy who touched the fireplace/chimney.
