Where did it explode for you? Problems during house construction.

Since we built with a general contractor, there was little involvement in coordinating the craftsmen. All trades worked well and reliably, except for the floor installer. Considering what they delivered, they should hand in their journeyman certificates.

However, we also felt the effects of the boom. The tinsmith who carried out the work on the house was supposed to waterproof the roofs of the existing buildings and connect them to the retaining wall. No, that's too much work for him - no desire. He said that literally. That was on 10/4/17. In February 18, we finally got someone through connections, and he finished in September 19.

- Concrete construction (reinforcement knowingly installed incorrectly, second time he wanted to do the crap wrong again) - Bricklayer (wanted to omit the horizontal barrier) - Electrician (delivered wrong switch program, electricity not checked for proper functionality -> burnt cables, non-functional PE, agreements not adhered to) - Sanitary/Heating (handles of shut-off valves placed between pipes, pressure tests not done, drains installed unreachable behind heating system, vent pipes laid in the middle of the room) - Plasterer (walls plastered crooked and uneven - bulge up to 1cm over 70cm, resin plaster used instead of agreed mineral plaster, windows not taped and therefore scratched) - Screed layer (laid 2cm more than calculated in the attic, main contractor refused static proof) I can't get it all together anymore. But if the main contractor shows up at my place again, I'll bury him on the property - it's big enough. However, I would still say that the main contractor is an exception. Sad is only the fact that he massively advertises both on radio, on YouTube, and with so-called construction advisors.

Things like:

- Tolerance of the screed layer installer --> "is ok and according to DIN" is not sufficient for the required flatness from the sectionally self-contracted tiling trade: expensive follow-up costs for leveling/sanding the "bumpy" screed

- Many things are not contractually defined precisely enough: for example, light reference value for exterior wall paint or freestanding bathtub (according to contract) does not automatically include a freestanding faucet, even if placed in the middle of the room --> follow-up costs everywhere, which add up

- Sanitary sample selection: significant surcharges by the executing company and the general contractor on the already not cheap prices in a bathroom equipment specialty store. This results in partly exorbitant prices for the sanitary fixtures, which are justified by the "installation effort." Ridiculous!

- Discussion about "what exactly is Q3 on walls and ceiling?" Since DIN only applies to plastered walls and drywall, not to filigree ceilings. Here too, the contract should have been formulated more precisely, e.g., "Ceiling Q3 - fully skim-coated and fully sanded" instead of just "Ceiling in Q3."

- Overall, I would prefer to include more things in the house construction contract up to the readiness for occupancy (painting work, exterior window sills at terrace doors, etc., etc.), because before contract signing the surcharges are fair (so you don't go to a competitor), all samples AFTER contract signing are, in my opinion, overpriced.

- Overall, everyone advised us: no matter how well you plan, there will always be unexpected and annoying follow-up costs, i.e., you only have one chance: plan financial buffers, more buffers, and even more buffers. Then you can stay completely relaxed.

all inspections AFTER contract signing are, in my opinion, overpriced.

it certainly depends on the construction partner. So far, I cannot confirm this from our perspective, for example.

Me neither. We usually settled accounts directly with the craftsmen.

I don't either. We usually settled directly with the craftsmen

Unfortunately, that wasn't possible with all trades...

Plumbing was the negative exception here as well.
