Own work - floor coverings, painting, tiling, what else?

I will now exclude the fact that people also like to do some work on their own house themselves.
However, it makes more sense if you, as an IT geek, turn your acquired knowledge in the PC/IT field into money, because you can do that faster and better. For the extra money earned, you pay a craftsman.
In the end, you have higher quality in the house and possibly even some money left over.

I don't know you and surely you also know which end of the hammer is the front, but the saying "Schuster bleib bei deinen Leisten" (cobbler, stick to your last) does have its justification.

If you have no idea and even emphasize it, you should better keep quiet.

And it’s always cool how some people come up with the idea that you just “simply” work more in your job and then the money just flies into your account.

From your sparse user info I know even less, but after such a post I definitely don’t want to know any more.

I mostly see it the same way regarding the calculation of wages. Overtime at work doesn’t benefit me because it is not paid out. So the calculation is pointless.

But regarding DIY work in general: You really have to be realistic. We (or rather I) underestimated the topic, but for us it’s not a big deal because we expected it. A delay of several months (currently it is 2) doesn’t bother us because we don’t have a double burden. And doing it yourself is really fun, you have to enjoy doing it, otherwise it becomes annoying at some point and then the quality suffers again.

If we had had the double burden, we would have had many things done because the risk would have been too high that we would have had to move in with the screed, like a few other neighbors. You have to be able to manage this risk, otherwise it makes no sense at all.

So far we have done the electrical, sanitary rough installation, and screed subfloor completely ourselves. A painter will still come for the wooden ceilings, we will also have the interior plastering and filling done, and we will do the floors ourselves again.

when I read this sugarcoating here sometimes....

-of course you HAVE to offset salary losses due to unpaid leave (or even quitting the job). to what extent is up to everyone to decide.

- it's also true that as a well-paid office worker you can easily break the calculated craftsman hourly rate (keep in mind that as an unskilled do-it-yourselfer you need about twice as long as the professional, so assume half the hourly rate).

- it's also true that overtime helps here somehow (either because you then take compensatory time off to work on the house or get it paid out to pay the craftsman)

- spending the much-praised free time on construction is nice and all, but there are people whose working time including commute already amounts to 11 hours. then only the weekend remains. you can’t keep that up for long.

- DIY without vacation/unpaid leave ALWAYS takes longer compared to the professionals (simply because you can’t manage another 80 hours on top of a 40-hour job... (keep in mind that as an amateur you take about twice as long as the professional)), which delays construction and increases interest on the amounts already paid out. during the longer construction period you also pay rent longer and possibly have longer commutes to work or standby interest etc...

what has been completely neglected here so far: warranty. with some trades theoretically irrelevant (painting), with others it can get really expensive (e.g. sanitary). plus the excuses of the other trades that you caused the damage yourself and have to prove all that mess yourself.
furthermore, as a layman you can also quickly mess something up and cause enormous costs. a classic example would be screwing in lamps on the upper floor and scratching wildly at the vapor barrier with the screws until it’s punctured. no one notices until the attic suddenly turns white/black.

if DIY, then it must also work properly and be relatively risk-free for the overall project. whether the tiles are crooked in the end is your visual problem, if the underfloor heating beneath the screed leaks it gets really expensive... ps: DIY can also cause costs if the following trades have extra work due to your botch job

Certainly, one must also offset their own contribution, but here there are enormous differences in the possibilities due to income and also the contractual arrangements with the employer.

For example, I have no possibility to do overtime at the company which I could compensate with time off or have paid out.
Accordingly, I cannot generate money from this which I could use for craftsmen.

So I can only use my regular vacation days as well as weekends and the time after work to carry out the work in the house myself. But this time does not bring me any money anyway, only the labor I can contribute.

It is of course different if my employer offers the possibility that I get paid for overtime. If my wage then covers the craftsman's hourly rate with 2 overtime hours (assuming you need about twice as long), it obviously makes no sense to do it yourself. If you even earn more in those 2 hours than you pay for the craftsman, you definitely should not do it.

It is of course difficult when, in the case of a new building, it concerns trades where you do not do part of the work yourself. Here you have to make sure that it also fits into the schedule.

You also should not rely on other people (friends). You get ditched faster than you think. And even with family you have to plan carefully.

Since I am planning to buy an existing property and to do the renovations and refurbishment mostly with my father who is a trained craftsman with years of experience who knows what he is doing and has already gone through it all (partly several times) with his own house, I also know that I can rely on him 100%. For helper jobs like removing carpets and wall coverings etc., you can count on friends, as usually someone can be found to help for 1-2 days and such things are usually done quickly.

But in new construction, such things do not arise anyway.

PS: So I believe or hope that no one wants to provide their own contribution and take unpaid leave or even quit their job for it!

Payday, you should still not present your own experiences as universally valid - no one here is describing sugarcoating. Still, there are supposed to be people who can push themselves even further alongside their regular work.

I am often still on the construction site after work, on weekends anyway - if I didn't have children, it would be much more, but I can't change that anymore.

You write as if that were only possible on weekends.

There are supposed to be cases who no longer pay rent and for whom warranty on certain trades is just as irrelevant...
