That’s because the vast majority of actual skilled professional tradespeople work in commercial and industrial construction, the talent level for residential construction is not very high. There’s also a lot more oversight on commercial and industrial projects (engineer/architect/owner’s representative/construction coordinator) that catches a lot of laziness issues like the one you noted in your post. Commercial and industrial customers expect much better warranty terms than residential customers and it’s not as easy to cycle through a series of corporations on the commercial/industrial side since some opportunities require company history and experience to qualify for even working on a project, leading to contractors ensuring their work is done correctly, since they’re on the hook for repairs down the line. I know there are skilled people that work in residential construction, but on average the skill level is much higher for commercial and industrial. I may be biased as I work for a commercial/industrial contractor that uses union labor.
