Price increase after order confirmation / contract conclusion

It is still open which trade or contract volume it concerns.

Which trade and measurements are involved?

Because if he pulls out halfway through construction, because you calculated too tightly, you haven’t gained anything either. Finding someone to finish a half-finished building is probably very, very difficult.

That could lead to, as we have read here in the forum from the Fleischerhaus: too cheap can mean insolvency of a company. Is that helpful to everyone?
The situation with building materials is probably very tense at the moment, which one should realistically consider.
I find this “sliding agreement” interesting – with it you could potentially benefit from falling prices (although that is of course not realistic).
What if he obviously miscalculated? Would you insist on paying the lower price?

Loss of trust and such. Quarrel even before the first shovel strike!?

One doesn’t have to start shooting sparrows right away and speak of loss of trust when one can’t even speak of a disagreement yet.

@ ypg: Everyone has their own experiences after all...

It is about the roof ([Dachtuhl und Dacheindeckung]). As said, we do not yet know how high the price increase will be. Based on that, we will also make a decision. But as described, there is a signed contract. And normally all contracting parties have to adhere to it. If we were to cancel, we would also have to pay a corresponding penalty. As mentioned several times already, we are aiming for an agreement and not for conflict. Just want to know what rights we have.

As you might have noticed, wood prices have exploded by 50%, so if prices need to be increased for a trade, then in your case, it would be for the roof structure.

However, this should maybe only be €1,000 in additional material costs.

I wouldn’t jeopardize the construction site for that. I think your approach is good, wait and negotiate with him. All other new offers would also include the new material price.

The probability of falling prices is almost zero, and moreover, how are you supposed to prove that as a customer? In my opinion, it also contradicts the Building Code; the cost risk generally lies with the contractor.

If the roofer offers a price, then concludes the contract and does not secure the material on time (at the calculated price), that is his risk. The question is, is there a plan B that would be cheaper than plan A including an addendum? There must have been other offers, of course you can actively approach them to see if they are available and still willing to match the price.

I would be interested to know how you resolved the situation...was there a price increase and if so, by how much? We are currently in a similar situation
