Licensed contractors come in all shapes and sizes. Some are competent, some are not. Some are honest, some are not. Some are righteous, some are bandits. What they have in common is a license. The license is a ticket to a decent living or permission to steal.
If the licensed contractor is inept, inexperienced and clueless, every dollar taken is a stolen dollar. I have encountered all stripes; human nature is to remember the demons. Angi's List should have an emoji with horns but alack and alas, making the list is making money. Angi makes money, the contractor makes money, the AHJ makes money.....it's a crap shoot if that money bought anything worthwhile.
There are contractors that care about their fellow man. They know where they are headed. Their best is good enough and they deliver it always. You can find them on a tiger's list....for free. But then of course you would have to know a tiger and the tiger would have to like you*.....a tiger's list that's exclusive....you can't buy a seat on a Tiger list.
*Bad people tend to attract likewise, bad people.
