Hi, just have a quick question. Anyone know the ball park figure for changing door locks. Theres 2 locks that are in question. Had a bit of a domestic tonight, went to ask the (ex) housemate why he hasn't done anything with regards to cleaning/upkeep of the house in exchange for reduced rent and things just spiraled into, he is moving out by this weekend and an agreement of his "unused" advance rent to be returned minus cost of locks changed so just seeing what figure I'm looking at to work with Bit worked up at moment, up to the point I wouldn't be able to use google to search for this.. Thanks.
