This was a Groupon purchase and I couldn't be happier.
Stuart B called and told me exactly when he would be here and walked me through the entire process when he arrived. He asked before and after the procedure if I had any questions. He was so thorough that I had none.
I was amazed at the amount of drywall pieces and other building materials he was able to extract as well as the amount other particulates.
I won't have to have them back now until 2018 and at that time will not mind paying the full price.
In a nutshell: prompt, courteous, efficient, knowledgeable. 10/10 vote from me.
