Find the right trade
Which tradesperson do I need?
Describe the problem the way it looks, not the way a directory names it. Click your symptom and get the right trade, whether DIY is sensible, and what to say when you call.
The right trade saves twice
Calling the wrong trade costs a visit fee and a day; calling a general handyman for licensed electrical work costs considerably more than that. The dividing lines are simpler than they look: water systems belong to plumbers, anything on the mains side of a plug belongs to a qualified electrician, height belongs to roofers, and the long tail of small mixed jobs is exactly what a good general handyman is for.
One honest habit beats every directory: describe the symptom, not your diagnosis. "The breaker trips when the kettle runs" gets a better-prepared visit than "I need a new breaker", because half the time the breaker is the only part working correctly.
