Opinion on various prefabricated house providers desired

The chemical stability of silicones is well known. Why do glaziers use silicone on the pane? Why are car windows glued with such compounds? Why are wooden decks on ships sealed with silicone mass? Etc. Because they are UV resistant and stable.

The decision-making bodies have many interests to balance, and many of them are contradictory. In the end, the measures that sell well and whose lobby groups have the most support are usually preferred. Lobby groups explicitly does not only mean industry lobbyists but also so-called environmental aid organizations and associations that have focused on specific issues. Climate protection through insulation currently sells well. However, in the overall balance, this is questionable and causes problems in practice. The main problem here is the combination of many isolated individual measures instead of a coherent concept (anyone who finds parallels to the current crisis management may keep them ;)). And a cross-sector emissions trading system, for example—which would solve the CO2 problem in the overall balance without many interventions—is simply unpopular, especially in the green spectrum.

But it would only solve the problem in the balance (in the sense of the eponymous patient paper).

It is probably always

I cannot confirm that. The seller did have all the prices ready, but I had to painstakingly extract them from him. And basically, he did almost nothing and was just waiting for us to sign.

What good is the best salesperson if nothing fits afterward? Better the slowpoke seller if everything fits afterward. And as "uncomplicated" as it went with Schwörerhaus in every respect, I can only recommend them. Except for the topic of soundproofing in the house, but that is my part, I should have booked the soundproofing package back then. Although I do not believe it is the same with other prefabricated houses that the wall construction is the same.

The best salesperson is of little use to me. But a bad salesperson drives the customers away beforehand. Even after 2 appointments, I still didn't have the feeling that I had a somewhat reliable estimate of the price that would come my way. Others were clearly better at that. And the poor communication doesn't exactly make you believe that everything will be great in the end. Otherwise, they would certainly have remained in the shortlist for a longer time.
This is not meant to be a plea against Schwörerhaus or anyone else, but I believe many companies underestimate what they lose when they use bad salespeople or commission-based representatives who are only supposed to bring in preliminary contracts as quickly as possible.

But that would only solve the problem on the balance sheet (in the sense of the homonymous patient paper).

Only if you sell off the certificates cheaply or issue too many because you don't want to burden the industry. If you reduce them every year, the emissions will reduce as well. Only that happens where it is overall cheapest to implement, whether that is in airplanes, cars, power plants, or Grandma's oil heating system from 1985.

Except for the topic of soundproofing in the house, but that’s my part, I would have had to book the soundproofing package back then. Although I don’t believe it’s the same with other prefabricated houses—the wall construction itself.

No, other providers sometimes only have a drywall panel without wood behind it... so it can definitely be worse. We dismissed the soundproofing package, and our doors are also somewhat better in terms of soundproofing. I’m curious how it will turn out. In 2 months we’ll know more :D
