Hi, i have just been told by my conservatory builders that i have 2 manholes that need to be relocated, or if that is not possible they can be raised and sealed on the floor of my consevatory, obviously for accessibility, these will be basically inside my new room. i am concerned of smells or gases building up. please can someone reassure me that this is THE NORM, thanks
