"Remember the days when you could trust a contractor to do an amazing job, You didn't need an estimate because you knew they would never rip you off. Their work and attitude were always exceptional. Well, the days of old are back with Spyglass. He is on time, first class, fabulous work and trustworthy. He does our window cleanering, gutters and special projects we need as elderly clients."

"Matt and his hard working team cleaned all our windows, screens, tracks, etc. In pre for a wedding we hosted at our home. They did an outstanding job, we're very conscientious and efficient. They're customized water pH system was interesting and efficient, allowed for streakless drying. Thier cost was reasonable for all the work it took to complete our home (~ 50 panes). Matt and his team were super nice. Several of our neighbors are planning to hire them. I highly recommend Shine for your window cleaning services."

"I really appreciated the time they took to give me a fair estimate for my house windows. They got here on time for my scheduled appointment and got to work! I was really surprised at how dirty my windows were and amazed at how clean they look now. I am very happy with the quality and friendly service Phil and Seth provided. Can not wait for them to come back for my monthly appointments!"
