I bought a Living Social deal and am so happy that I did! Athan and Angela arrived on time and were super friendly and professional. They cleaned all inside and outside windows, plus the screens, in under an hour. I'm amazed at how good they look! My husband also commented that he noticed a "gleam" in the windows, as he was pulling up to our house. You can get on a maintenance schedule with them for service every month, or 2nd, 3rd or 4th months, and they offer an awesome discount for repeat customers. I'll definitely be calling back to schedule my next maintenance appointment with Crystal Clear!
