I ready a bunch of complaints about the Cleaning Authority. I don't know if this site is the place to give them praise, but I think they are very reasonably priced, very reliable.
They do a good job! We had used the Maids, a kind of cleaning swat team, who would descend on the house with four or five workers and blast clean the house in about an hour or so.
They did a good job, but they were more than twice the price as the Cleaning Authority. The other great thing about the CA is that they will work out deals to only do the rooms you most need, for a lower price.
