All I can say is "WOW!" These guys were awesome. They arrived perfectly on time and cleaned every inch of my 16 windows and 4 skylights perfectly. Screens, too! They were meticulous, friendly, and professional and even took their shoes off. There is not a speck of dirt on any of my windows despite some being in a tricky to reach location. They were reasonably priced and a pleasure to deal with. I can't wait to hire Window Cleaners NY again!
