"We were very concerned about the fungus on our roof. There was a lot of streaks and it took away from the appeal of the house. Gem came out and described the process in detail, answering all of our questions and concerns. 

We decided to go ahead and hire Gem for the job. The only word to describe the end result is “AMAZING.” Our roof looks brand new. It is cleaner than we ever could have imagined. 

Based on that we have hired Gem to clean our windows. We highly recommend Gem!! "
