I got a quote for 8 windows and a patio door, cleaning inside and outside, for $90. The guy showed up at my house and started cleaning windows outside without letting us know he was there and which windows I wanted cleaned. He then said he was only going to do the outside because the insides look clean - which they hadn't been cleaned in years. He was a poor listener and did a rush job, thoroughly frustrating my husband. So I guess I paid $90 for an hours work! Would not use them again.
