Worst - DO NOT USE them at all. They are a SCAM. Bought Living social coupon, scheduled the appointment online in couple weeks in advance, made all my work and other arrangements and kept the house ready for Grout cleaning, nothing was left on the tile. The Appointment was scheduled for 9 - 10 AM and some id*** calls and says we will not show up today , my truck is in workshop.. can you come tomorrow.. No we can't ... another day ?? I will call and let you know .. he never called back. Wasted my time, efforts and all the inconvenience - but this JE** was very easy to say we can't come. DO NOT USE THEM, they don't deserve to be in business to be playing around with customers.
