I can only give you my experience with Merry Maids. I also wanted a deep clean for my downstairs area. I wanted the same thing you wanted. We met with someone first who gave us a list of everything that would be done and it was impressive. The cost was over $300 and we did it because we had just gotten rid of a dog to help our sons' allergies (sadly the dog was their main problem) and to just get the house clean. We had two people show up and they cleaned for several hours. The problem is they didn't do as promised. Watermarks were left near the tub, not all the doors were not cleaned, they didn't touch the baseboards that I could see, kitchen table had food on it left from breakfast, and the cabinet doors did not appear to have been touched. These things were on their list. So I called and ask someone from Merry Maids to come to my house and see what $300 bought me. They didn't appear to even clean under furniture. We would have gladly paid $100 for the clean because they did clean, but in the end Merry Maids would not come and see how the house was cleaned and they refunded all our money. My suggestions is be at home and watch them and look at the list if you use Merry Maids. You might get a good crew, but we did not. I was so disappointed.
