I am purchasing a house and the survey stated that the artexed ceilings may or may not contain asbestos. The surveyor stated the artex was in good condition and has no damage and therefore if it is skimmed it will seal the artex. I need my living room skimmed (10’9ftx 14’10ft) a bedroom (7’9ft x 12’9ft) and the ceiling on the upstairs landing. Can artexed ceilings be skimmed and roughly how much will this cost
