Experiences with companies that offer complete renovation.

What I notice: The quantities are inconsistent.

This is basically the first version of the offer. We have already been there and discussed it in more detail. There is also an offer with figures. It was presented to us, but the contact person does not want to release it that way. Other customers have taken something like that to the competition, and they simply copied it. So they saved themselves the work of creating their own offer. We were also offered to establish contact with other builders to inspect the quality on site. Based on experience, the total costs of the company's projects are within ±5% of the tendered sum.

Many things are the builder's responsibility. Make sure that this is what you want.

What exactly do you mean by that?

10 power supply
50-120 own contribution / demand item
200 last ceiling paint own contribution
Etc
