Short version - As the title says, a contractor quoted for some work on our house as part of kitchen renovation. He quoted off the plans, we (foolishly) agreed the price by email, but now he says he can't do the work without very expensive extra work. Are we committed to paying for the work we'd originally agreed/is he committed to delivering it even though he says it's undeliverable?
Long version...
The contractor was introduced to us as part of the renovation process via the kitchen company. The price he quoted (based on plans only, he wouldn't come out to see the house because in his words "I've been fitting floors a long time") was roughly in line with what we'd expected so we accepted the quote. The kitchen firm had surveyed the kitchen so we thought they, as experts with 30 years experience in kitchens, would have picked up on any challenges and informed their recommended suppliers. In retrospect this was stupid I know, but we'd paid extra for the convenience of having the work coordinated by the kitchen firm and we thought that meant we could trust them to, well, coordinate the work.
When he came to start work, the floor guy saw the kitchen himself for the first time and decided the floor needed extra work. The floor slopes a bit so he said it needed to be levelled. Two weeks later we've finally got the additional quote which nearly doubles the cost of the already expensive floor. He hasn't done any work yet but the kitchen has been fitted on blocks where it slopes (anticipating the floor being levelled) so we kind of have to level it now otherwise part of the kitchen will have a gap around the bottom.
I'm trying to work out where we stand now. We accepted the original quote in writing (by email) but he says he can't deliver that without billing us a significant amount of extra work. Can he make us pay for the original quote even if we can't afford the extra work and have to go for a cheaper floor? Can we hold him to his original quote on the basis that he should have driven the 10 minutes to take a look?
If the original quote for flooring of one room had come in at this amount I would have said no and looked for another option before we started the work. There's no way this house or project is worth that. Even the original quote was pushing it. But now the goalposts have shifted half way through the project I feel completely shafted and worried he'll still bill us for the original amount.
