I work with several low-voltage guys on different jobs, both new development and retrofit. It is exceedingly difficult to find good cable guys. Running parallel to romex, staples through the middle of the cable, minimum radius as a non-existent concept... Like you say, the competency is the hard part to find.
And before anyone adds on with 'lol pay more', they try. The people just aren't there.
Almost all homeowners can't pay more than commercial jobs (for the same amount of billable work).
Ergo, if they can, tradespeople take commercial jobs.
Which leaves residential tradesperson as something of a lemon market. (And I wouldn't want to put up with one-off job, haggling about payment, if I had commercial options)
It correlated exactly with Covid. And the folks I’m talking about are the same folks pre-covid. They didn’t retire, they’ve lost their minds, very noticeably increasing in particular over the last 3 years.
This fall is part of a steady escalation.
It appears to be heavily correlated with the insane propaganda floating around too.
