In my socioeconomic circle, ( blue collar), not many have outside help unless they have family or friends with free time & skills. We were conditioned to do everything ourselves, (& it allowed H to rationalize that he should hang on to his ancient truck!)
H does 80% of the work on our vehicles, and we do our own painting & prep, and repair of appliances.
The only things we’ve hired out has been the roof, and installation of washing machine & water heater.
( although the installation of washing machine was messed up & it took a while before H looked at it and decided that it was caused by installation, and not our ancient pipes, H replaced a part on the machine & now it works great!)
We hire help to deliver soil and bark (20+ cubic yards at a time). We handled pretty much all appliance installation (if the free delivery was offered, we took it) and furniture hauling from stores (the only thing we asked to be delivered was the big mattress). Our roof is still OK, but when the time comes, it will be handled by hired help. Ditto gas furnace and water heater, although Mr. replaced the circulator pump on the water heater all by himself. Oh, and we had ABear remove the big dead Douglas fir in our backyard and AtoZ to get rid of the stump.
Other than that, we do it all with our 4 hands: building fences, walkways, retaining walls, planting, etc. It is fun.
We’ve had major work on the house done: scraping and painting exterior after we gave up on doing it ourselves, just to high (I do all the interior painting myself), new roof, some repairs involving carpentry. Periodically we have had to have an arborist come and cut down trees or remove fallen ones. There is a handyman in business for himself who has done some small jobs for us that are beyond our expertise.
We don’t have any “regular” help with anything, unless you count having the furnace cleaned once a year. 
Prior to having kids (when we had plenty of time to do it ourselves!) we had someone come to clean, had folks who took care of the yard, people in to paint and wallpaper, etc. Now we only have folks come in to do things like the roof, replace the furnace, etc. We are short on time and money but do what we can on our own.
Of course I have to weigh in. When our kids were young we had full time live in help. Now I have a housekeeper twice a week. When we have parties I always hire a woman that I know who has two daughters.
We have a gardener (and crew) who comes once or twice a week. Before I got sick I did a lot of planting and design myself. (the gardens sold the last house. Now, not as much…but I designed the front and back of our home. Someone else did the heavy lifting.
The people who work for us are paid very well. Housekeepers are paid $18 an hour…the gardeners are 25 an hour. No indentured servants here…
We pretty much do everything we can ourselves. I recently re-did a bathroom and did it all myself including flooring, new counters, and even soldering a bathtub pipe repair, but did have one section of very complicated tile that a friend helped me with. Years ago, I did pay a house cleaner every other week for a short time when my H was working out of state and I was working 10 hours a day while juggling little kids. We used to pay someone to mow our lawn because kids and husband are very allergic to grass, but we have since torn out all of our lawn. My husband does the pool maintenance. We will hire someone to do the roof and while we have always done all of our own painting, we are going to hire someone to paint the outside soon. Now that our last kid is close to finishing college, we have a little extra and may start hiring out some of the bigger jobs.
We used to do it all by ourselves. h was fortunate to learn a lot of building/repair skills from his dad. he has built patios/decks and finished basements ( including bathrooms) at all the houses we have owned over the years.
Now that we are older and have more money, we hire out more. a master bath remodel is hopefully happening soon and someone else will do it. I have cleaners in every other week. Certain repairs are hired out.
I like doing stuff myself, but it takes so much time!
Plus now that the arthritis in my hands is getting worse, it is harder to grip, and that is so frustrating.
Some days I can barely do laundry, let alone build a fence!
( H has been hanging onto wood scraps that he was " going to use to build a fence". We couldn’t agree on what type of fence. I wanted lattice top, he hates lattice, so I planted hedges to grow until he comes around. )
Something I struggle with is the notion that it is OK, to hire help.
My parents didn’t hire help either, but my Dad had friends that were plumbers & electricians, and he had his father in law, who had been a farmer in the Midwest and insisted on helping with everything. Grandpa helped us paint our own house when we first bought it, and it was all we could do to keep him off the roof!
We bought close to my grandparents, so we could help * them*, not so they would help * us*.
My in laws, who still live in their house, don’t hire help either, they have H fix it.
I think it would be faster if they hired it out!
My job involves traveling quite a bit. We have a dog walker we use if my H’s work schedule doesn’t permit him to walk the dog in a timely manner.
Biochemist husband & theater tech/design kid means that the paint jobs are spectacular, household pests live in fear of us, and everything else we get professional help for.
Thnakfully my parents have the money to hire out a lot and are more than willing to do so. My siblings and I do not live close to them.

LOL, @happymomof1 ! This biochemist takes care of the pests and weeds in the most organic way possible. Mr. B has had some serious physics and chem. engineering training, so he takes care of things that are “processes.” 
I took shop in school, hated it, but I know how to do a lot of stuff due to that.
Mr. and I just recently installed 2 ovens: 2 x 220V outlets needed to be wired, drain and water lines to and from the crawl space needed to be run, and everything had to look neat. It seriously helps that Mr. listens to my aesthetics comments. My dad was a superb handyman, but goodness, the neat looks were not totally important to him.
BTW, I think we did a better and smarter job installing those ovens than a contractor would do (I came up with a great design idea). And we saved $800 on the install.
I do all of the plumbing, painting, carpeting, etc. My dad was a professional plumber and I grew up around tradesmen so I learned quite a few tricks of the trades.
I would hire out the roof though. I don’t do heights.
We do everything ourselves. Have paid a roofing company before – and would again – both times were on insurance. But all appliances, plumbing, housekeeping, electrical, yard work, laundry, cooking etc. we do it. Pay someone to watch/feed our animals if we are out of town. Paid someone to do a final clean up on a house we moved out of once, but that is because we were at the new house painting, cleaning and plumbing!
I’m married to a mechanical engineer. He can do anything. Which is great but things are done on his timetable, which would not be anyone else’s timetable.
I would say that being married to my H is like being married to a contractor. The end result is really nice but there is no end result lol! I should be nice and say that he’s not that bad and we save money, which is true.
H decided that he doesn’t like to repair the car so we have that done. He does not like to be on the roof so he wouldn’t do that either. He wants to hire someone to take some trees out, I will get a quote, he will claim that it’s too expensive and he can do it. Then he won’t have time. Sigh.
I see roofs emerging as a trend… If you are a roofer, your job is secure! 
It is a nasty job though.
deb, I completely agree about timelines, but I really hate to sit and wait for contractors to show up (and then some don’t show up, like the furnace dude!).
While H and I were both working we had a housekeeper. When he retired he became that housekeeper. We enjoy working in the garden and we can be found digging around each weekend, but we did hire a landscape designer/ botanist to work out the plan and his guys to amend soil (three feet down is a lot of digging and mixing—and we ended up with several truck loads of rocks and roots). I do paint walls, but exterior is for nired brave men with ladders
Most repairs and appliance installations are left to the experts. Too many situations in the past lead to “you ruined it” arguments . Repair guys are cheaper than marriage therapists. And car repairs? Naaaaaaaaaah --I would not let dear H go near my car.
We have mechanics work on all our cars. We hired installers for cooktop (corian needed trimming to fit). We hired contractor to install windows (he did a junk job), doors, latest dishwasher (H has done it previously but was tired of installs and we got a good deal with Sears). Hired mechanic for washing machine and dryer. H has installed built in microwave, does yard, and is S L O W L Y painting our house. We have hired an interior painter decades ago. H repairs most things. He deconstructed our fence and is slowly rebuilding it. We have many projects in progress. LOL!
We also have a property manager for rentals, who handles everything, including repairs, termite treatment, and hiring someone to do yard work on the rental home.
We hire out car repair and large jobs around the house and yard, but we should sub-out more than we do. It’s a constant source of stress with things not getting done and dh insisting everyone over charges. I could go on, but I think I will leave it at that!
