What it is

A mobile service where you inspect older homes, take small samples of suspect materials (ceiling texture, floor tiles, pipe wrap, siding) and send them to an accredited lab. You then give the owner a plain-language report.

Your first three steps

  1. Check your state's environmental or health agency for asbestos inspector licensing and find an approved AHERA building inspector course
  2. Get quotes for professional liability and general liability insurance, and set up an account with an accredited asbestos lab
  3. Buy a basic sampling kit and PPE, then introduce yourself to local remodelers, home inspectors and real estate agents
Who pays

Homeowners planning a renovation or worried about an older house, home buyers, landlords and small remodeling contractors.

How it makes money

A flat fee per visit that includes a set number of samples, plus a charge per extra sample and rush reports. Referrals from remodelers and real estate agents bring repeat work.

Skills that help
  • Careful, methodical inspection
  • Clear report writing
  • Explaining risks calmly to worried homeowners
  • Comfortable in attics and crawl spaces
Watch out for
  • Many states require an inspector license or certification, so check with your state agency and your city or county
  • Professional liability (errors and omissions) insurance, as a missed sample can lead to a claim
  • Disturbing materials while sampling can release fibers, so follow proper sampling and PPE procedures
  • Check rules on handling and disposing of samples, and on testing in rental or occupied homes
  • Do not offer removal yourself unless you hold the separate abatement license your state requires
