I have a one story 1200 square foot home and was quoted $360 for a deep clean, which was more than other places I inquired with, but I had been personally referred and they had good reviews. I ended up paying $500 when it was all said and done. I almost got ill having to pay that much. They did a good job but for $500 I expected to see NOTHING missed, but there was still dust on shelves and spots on the floor. Everyone was nice to deal with so if you can afford it, great. If not, find somewhere less expensive that I'm sure will do just as good of a job.
