I’m a millennial and own a home and can fix things. I do get experts in sometimes when I am less familiar with the job. What I found was that the previous boomer owner did a lot of things wrong. I can find the code violations, but may need an expert to come up with better solutions. I shadowed my electrician and don’t need him anymore. Still have my plumber in a bit for now.
The previous owner of my place "fixed" the front door handle by gluing the mechanism into it. Now if I want to change my locks I have to replace the entire door. Cheers mate.
Acetone removes glue typically. Sometimes, when you think something is glued in hard, there is an extra screw that you missed.
My garbage disposal just broke. Turns out that the previous owner rigged the dishwasher drain in-line after the disposal, so that there is a chance that disposal water can kick-back into the clean dishes. Fixing that currently.
The kitchen hood vents into the attic, so have to fix that. The owner created a nest of electrical wires in the attic as well, so ended up creating a channel for them and organizing them so they are fastened nicely to the joists.
They created an unstable loft in the garage, so had to demo it since it was ugly as well. The list goes on and on.
In my house (just bought it, renovating) the light switches by the front door seemed kind of loose behind the cover plate. Finally got around to looking at it and found that the switches and their plate are attached to the wall only with caulk; the metal box they're supposed to be screwed to was somehow pushed a few inches into the wall. For bonus points, one of these switches produces a few seconds of loud humming when flipped followed by the main circuit breaker tripping.
Their is a fault in the circuit. What is the switch supposed to control? Had the same thing with the circuit for the lamppost. The wire for it wasn’t buried deep enough by the previous owner and became compromised over time. For the plates, they make longer screws and also spacers for times when the box is seated too recessed. If you don’t have those on-hand, you can remove the box and seat a new one properly, but that can be a lot of trouble depending upon the circumstances.
