I bought a 15 year old luxury home that, while well maintained by a housekeeper, needed a \"deep cleaning.\" Based on Yelp reviews, I hired Pristine. They were terrific. On arrival, they commented that although the house looked \"fine,\" it wasn't up to their standards, and got to work. 3 people worked all day. Other than a lunch break, I always saw them working away, climbing up ladders to reach high shelves, getting down on the floor, scrubbing tiny crevices with QTips. They were outstanding!  When they were done, I hired them for ongoing bi-weekly cleaning!
