Seal the back door? If got emergency like fire at the front door then how to escape? Feng shui of a house also need to match with individual's ba zi. Like joey yap said, see feng shui without the owner's ba zi is like go see doctor without bringing the patient. But the overall thumb of rules is the land at the back of the house have to be higher or equal to the land at the front of the house.
