Build started mid May. Not a huge job:
taking down conservatory
Foundations
Kitchen extension
Some internal alterations to 1 room
Kitchen installation (by a third party but they need to work around them)
Finish, decorate
They are still at stage of finishing external roof on extension, so still got tons to do. Not even done first fix. I think it will be easily 8 weeks more given the speed they work.
He didn't give me a time estimate at the start - we've used him before and he does a good job so we trust him even if we know he's not the fastest.
I paid a deposit upfront and have been paying a chunk weekly since mid May.
We are now 5.5 months on, I've paid him 82% of the total cost. I pointed this out today and basically asked if I should stop paying until they've caught up a bit and he said no, it's best to keep on paying. When I pointed out that there's only about 4 weeks left til I'll have paid the whole amount he said it's normal nowadays to pay up before the job is finished.
I think this is unreasonable and am planning to withhold further payments (or at best reduce them significantly) until some more jobs are ticked off.
What do you all think?
