Hey Rod; we also make the best money in repair. Until I retired in 2010, I always loved Thanksgiving and Christmas for the early afternoon emergency repair calls. Big bucks to be made there. When the kitchen or toilet won’t drain, or the water won’t shut off they have to call now.
Hubby's been a repair plumber for almost 20 years, and he never minds pulling call on the holidays.
Not only is the pay pretty good, folks usually tip......and offer to feed him too!
He nets around $60K a year, [which in Texas is a respectful salary] and the only degree he has is in an unrelated field.
