Per hour costs are between $50 and $90 and often include multiple cleaners. The square footage charges depend on the size of your house. In your case it would be cost $250. If it was less than 1000 square feet it would have been an average of $90.
I agree with Stewartbrock, The cleaning agents will charge according to how much Sq. Feet the room or the particular cleaning area covers. After reading to this I suddenly got remember about the water damage Anaheim happened at my sisters home as the bathroom pipe got burst and thus the water got spread all over the home. So to cover up the damage she decided to contact the insurance company as she already had an agreement with them for a water/flood damage insurance policy. Likewise, you should have also made an agreement with an insurance company for water damage so that they can control the further restoration cost or house cleaning.
