Hi
Q1. sometime in the houses past on of the first floors bedroom had its fireplace bricked up rendered over with cement. there is no air brick. Do i need to fit one?
Q2. the hearth has had the tiles removed and left bare. there is a slight dip in the concrete bed right to left that they were laid on. should i take up the area and replace with wood or use some self leveler to fill the area. (approx 3' by 1' 6")
