Comment: Brian Marshall was my technician and he did an amazing job. From the moment he arrived, he was friendly, professional, courteous and he explained everything he did. I had lots of questions which he patiently answered and he gave me a couple of suggestions as well which I appreciated. I will be calling back and scheduling him to do some work on my tile floors and marble and granite countertops. This is the second time I have used Dalworth for cleaning and I could not be happier. The only down side is that it usually takes 2 to 3 weeks waiting time, but I suppose you can't help that-it's a good thing, right? Thank you so much!
