Just talked with "Yes, and we were all amateurs, would do it the same way again."
However, I have to qualify that we partially worked inside with sanding plaster (bathrooms over the tiles, stairwell, hallway, corridor) and these jobs were done by a professional (my brother-in-law) with amateur support (my sister).
At times, there were 4 of us doing the wallpapering and painting work, of which two people (my mother and my wife) did not always help (looking after children; cooking; no jobs they could do).
My father worked for a total of 5 weeks, I 3 weeks (vacation) + evenings and weekends, my mother partially 3 weeks and my wife partially the 5 weeks. Father and I were usually on site from 08:00 - 18:00/19:00 (after that there was no proper light anymore).
Afterwards, we were completely exhausted and done. My father (almost 75) doesn’t take it easy and at the end looked like he was going to collapse from the chair.
We were able to get material cheaper through a staff discount. In terms of price, we were at 1,000 - 1,200 + BG payment.
We would do it again, but:
1. We would NEVER have expected it to take so long. I had estimated max. 3 weeks.
2. Without the enormous commitment of the family, we would have completely failed.
3. We made small mistakes that a professional would not have made. For example, when wallpapering the door inner frame of our sliding door. Currently, our little Pipel-Fritzen enjoy playing with it and pull small pieces of wallpaper off. First spot for rework.
4. Our living room (especially the ceiling) still looks sh... despite double coating with the best Alpina paint. Second spot for rework.
If you do it yourself, you also have the feeling: WE have built something in the house OURSELVES.
If you do it yourself: Don’t overestimate yourselves. If you run short on time towards the end (only little time until moving in), hire professionals. As already mentioned – we never thought the whole thing would drag on that long.
It went similarly for you time-wise as for us.
