Leviticus 14:43-45

43And if the plague come again, and break out in the house, after he hath taken away the stones, and after he hath scraped the house, and after it is plastered,

44then the priest shall come, and when he looketh, and behold, the plague hath spread in the house, it is a corroding leprosy in the house: it is unclean.

45And they shall break down the house, the stones of it, and the timber thereof, and all the mortar of the house, and shall carry them forth out of the city to an unclean place.
