Overall I'm pretty happy with the Brian's performance. I did have unusually high expectations that he'd be able to get out some of the pink and purple stains left by the previous owners' daughter but alas, a standard cleaning was no match for pink girl stains.
I believe Brian did the best job he could and was able to get a deep clean to at least sanitize my carpet from the previous owners' lack of carpet care maintenance. Although I'm sure Robert could repair the real bad spots, these carpets, the carpet in general needs to replaced. That is another tale for another time.
As far as Brian goes, he was able to give me an accurate quote over the phone with the information provided. He kept in good communication with me and let me know a previous appointment took longer than expected which was appreciated. Although I had high expectations and hopes that he would be able to get out the tough stains, he did tell me ahead of time prior to performing the work about the areas he said he'd have trouble with so I was well informed going into it that some of these stains wouldn't come up with a standard cleaning.
To anyone out there with really tough stains and old carpet, it may be worthwhile to just replace it if you can afford it, otherwise, Phoenix Carpet Repair and Cleaning can do a good job of at least sanitizing it or repairing small areas. Don't jump to conclusions about the website's before and after photos as those are of their repair service photos, not their cleaning service photos. Two different things.
I would recommend these guys and I would call them again if I needed more work done.
