We are having central heating fitted next week and was wondering whether it is safe for me to be in the house when the work is being done, the carpets (which are foamed backed so could be dusty) will have to be pulled up and new piping put in floors/walls also having a new bathroom suite being fitted. We have a two bedroom house. Not sure whether is safe so need some advice? Also would it be safe for me to paint? I have been stripping wallpaper have done it slowly over a few days and wore rubber cothes. I am 10 weeks and 4 days pregnant and this is my first pregnancy really want to do everything right and dont want to do anything that could harm my baby.
