I agree with the person you are responding to and your snarky remark bothers me to no end. No one will care more about your house and problems than you do so they will often do a more sloppy job and the only thing that saves their face is their experience of doing their job more often than you do.

There's always more things that needs to be done than time you have.

In practice you always need to prioritize between

1. what will you spend your time to learn and do it good

2.what will you spend your money to make others do it worse(coin flip, it may be good)

3. or not do it at all.

The choice is not trivial.
