We have some minor building works going on at the moment. A couple of our ceilings are in poor state and in a couple of places water has come through where we had a leak. The builder builder quoted to replace the plasterboard in the affected areas & said he would then skim the whole area. It turns out the work is being done by plasterers rather than the builder & they have arrived & are refusing to skim the ceilings as they are but want the plasterboard taken down & replaced. The quote for this is a few hundred pounds for each room. I feel as though I have no choice but to agree but am miffed that the work is going to cost over £1000 more than the estimate and I am expected to pay this. Shouldn't the builder cover part of this?
