I used Sonlight to clean the windows at a rental property and they did great. I used them to do the windows at my residence as well. I am out of their service area so got an extra $1 per window fee but it was still very competitive with other quotes I received. There was a small hiccup on cleaning the window tracks but they came back the next day and quickly fixed the situation. I will use them again going forward.

These guys were great. They responded quickly to our response for a quote, did a spectacular job, and even went out their way to do a little extra cleaning of our patio furniture at no charge. Their prices were very reasonable, we will definitely be using them again!
