"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."
