My level of household electrical competency allows me to replace wall

any repairs or replacements on the propane gas service or remove and
replace a water heater. I know you are more competent at these things
than I am, but...I'm not impressed with your level of finish work.

And if one tries, doesn't succeed, tries again and eventually succeeds, one has learned something.
In your case, nothing is learned but the cost of having someone else do the work.

It is interesting that as much as Harry likes to trash anyone who does
not have a college degree, he could not survive without those people.
I am sure most of them charge more per hour than he could dream to
ever make.
