I have been asked to lay 200 square metres of 130x18 engineered oak flooring. It is t&g and will be laid floating. I wondered if anybody would be able to give me an idea of how many square metres a proffesional is expected to lay in one day to give me an idea of how to best price the job. I think it is worth noting that this 200 is on two floors covering many rooms, thank you very much for any replies.
