This is my third time using 416-So-Clean. I think they did a good job. They arrived on time and the two technicians were friendly and easy to work with. I had requested a specific technician that I had worked with in the past and was told that I could have him. Unfortunately when the technicians arrived it was not the person I requested.
The reason I am only giving them an '8' rating is for two reasons. One, I booked my appointment far enough in advance to get my requested technician and he was not the one they gave me. Second, there were still several stains on my stairs that were not removed. I don't know if the technicians had used the special stain pre-treatment that was used the other two times. And I only noticed the stains after they had completed in daylight.
Both technicians showed up on time and completed ahead of schedule. And they moved furniture to get underneath which was a plus. I will use them again but would prefer the other technician.
