? If you're doing that much reduction in your estimation, couldn't the same be said for software?

The labor itself might be low skill, but the experience required to do the job well and to create a lasting structure takes an enormous amount of time. "should I use ceder, spruce, pine or Aztek for the exterior door casings? Should my subsill be 7 degrees or 14? Should I use felt paper or tyvek for my weather barrier, which type of tape should I use for each type?"

And this is why companies hire a hundred fresh grads for every gray hair. 99x/100 they don't need super high quality work output.

In all trades there's a hesitation to look at something and say "screw it, it doesn't really matter, just do what's cheap" unless you're being told to and software isn't immune from that (in software "told do" seems to come mostly in the form of time pressure whereas in the trades it's what the number job is paying). Sure it's nice to do "good" high quality work but a lot of the time it really isn't necessary or it's strictly wrong because whatever it is you're building needs to be built to a price point. It's only when you push things to the limit do all the little marginal details (the stuff the experienced pros get right) start mattering. That tends to accidentally happen more (at least in my estimation) in software than the trades because labor is so expensive and code is so easily portable.

Also, janky setups and quick-n-dirty fixes abound in all trades. You just only see them in trades you know about.

Not really sure why you are being downvoted. My own experience aligns with what you are describing. For most residential work a homeowner can do a solid job as long as you are handy and willing to spend a little time familiarizing yourself with building codes and the appropriate techniques. Being a professional means being able to estimate accurately, meet those estimates, manage multiple jobs, etc.

If timeline isn't the most critical factor a homeowner can do an excellent job. Often even better than the professionals because you will be willing to spend extra time and attention to get everything perfect.

And yet there is me, having to go to Home Depot 3 times for a simple job, and still managing to mess it up.

not sure if you've ever watched a crew work but one of the reasons for the cheap labor junior guy is to run to home depot.

>> but one of the reasons for the cheap labor junior guy is to run to home depot.

And then get the wrong stuff, which the contractor will make do anyway if there's even the remote possibly it will work. and so on. After a while and some $$$ wasted you will get a feel for what's reasonable and what's bogus.

You speak pretty definitively on the topic. I'm guessing you have some experience with construction that's worth sharing? Would love to hear a positive story of how it turned out!

I spent a few years doing under the table construction and also picked up the skills to work on mechanical things around the same time. Then I went to college, got a career and spent some money picking up the skills required to work in metal. Electrical and plumbing (not just for water) are things you kind of have to pick up along the way. I'm no means a professional at any of these skills because I don't get 40hr of practice a week. Nor am I unique. A lot of successful people from blue collar backgrounds wind up with similar skills. Even though I have software money now I couldn't afford to pay people to build the things I can build myself.

I agree with throwaway0a5e:

I became a homeowner as a never-interested DIY with EE/CS degrees. We had an unfinished basement that we paid the builder to finish only the electrical, plumbing, and framing. I'd always heard drywall'ing was easy so I left that for me to do.

At the time I knew nothing about lighting, fixtures, eletrical work, etc. Ended up agreeing to J-boxes for basement lights rather than cans, and a few other money-saving things (for the electrician).

Before doing the drywall myself, I ended up rerunning all the basement lights, running tons of outlets, installed an electrical subpanel in my garage, new plumbing lines, etc. All inspected and approved on my own permits.

I maybe watched ~200 hours on youtube (easy to do at 2x speed) and read a lot of electrical and plumbing code. But when I was done it was "done right" and not done to "save money".

I ended up saving a ton of money on the electrical and plumbing, easily in the thousands, and only saved $700 on the drywall labor. Moral of the story, don't hang your own drywall by yourself. Pay for it if you can't get a couple friends to help.

Electrical and plumbing are relatively easy compared to anything that requires accurate measuring and cutting.

The latter can really kill a project if you can't get it right consistently, preferably first time.

That's where the skill comes in - not just the physical labour, but the experience needed to make allowances for material tolerances and other possible gotchas.

Professionals (should) have that knack, amateurs rarely will.

Is that from experience?

Generally all contractors say "the next guys will take care of that". For example, when framing you don't really care if the studs are really straight or if the walls are square. The "next guy" will take care of that.

True enough, when I was drywalling I had the builder come back to take care of some bowed studs that should never have been used.

I've also volunteered at Habitat for Humanity and can confirm that very little "accurate measuring and cutting" was occurring. They'd quickly measure some things, shout out numbers, and then use a circular saw to rough cut it out. But that was it - they didn't refine it after that and went about their merry way.

I have to believe that the accuracy of a foundation is more important but I think it's a fool's dream. They get "close" and they're checked out before the "next guy" has to fix it.

Maybe I am just bad at it but I can't get anything done DIY to fit properly. It's always off by like 1-2mm which means holes don't align, there's a gap in the baseboard, etc. I have to throw the entire part away and then pay someone to do it properly.

Unless a 3d printer or CNC machine is responsible for the accuracy you better count me out.

Ah, I did pay someone to do the millwork and trim work. You need a very accurate miter saw and a lot of experience to make perfect niters. I’m getting there but I still get off by a 1/16tb” to a 1/32nd” often.

The finish work is the final last guy. The guy that did our trim would randomly yell out swear words every 20 minutes. His life is hard. And he was expensive.

A couple of jobs a contractor I used for a long time (before he, sadly, retired) involved some drywall. He got drywall specialists to do it. He said they were far faster and cheaper than him doing it himself.

I do have a guest bedroom in my house where I once had some time during a holiday shutdown when my job situation was a bit perilous. I had some crumbling plaster so I put some drywall up. It's... functional.

Painting is one thing I do myself. I do it enough I got reasonably good at it and--for touchup--I can reasonably take shortcuts that someone I was paying couldn't.

For N=1 failure can be catastrophic.
