Jason arrived first thing in the morning and took such care to wear those booties each time he entered. ( I really appreciated that as my carpet is nearly new.) He explained what he was doing each step of the way. I had only use a company before that had used a portable vacuum and what a difference this truck mounted method made! Its only been 3 days and I can already tell an improvement in our breathing and the amount of dust in the home. The price was higher but the company took such care to do a through job. I highly recommend.
