I have had several issues come up in a survey that our buyer wants put right. He want to complete and move in middle January 2018. The work that would have to be done is: all ceilings in house re plastered, parts of bedroom wall and bathroom wall chipped off, sealed for damp and plastered. Spraying for woodworm in loft. Electrical work in loft. I assumed he would take an adjustment in price. However he wants me to get all the work done myself before completing. We are 20 days from Xmas and I have children and a disabled person at home with me. It would be a major disruption and I would rather know money off for the work to be done later. Do you think this is reasonable?
