The team was on time, professional, friendly, and willing to do what it took to clean the windows inside and outside. When the sun came into the sunroom the next day, I noticed streaks. I contacted Shawn , the owner, and he sent the crew back within the hour. They realized that a new crew member had not learned his task fully and they re-did the windows on the outside and inside. The crew boss mentioned that the call back was a "heads up" that the new crew member needed more training. No one was mad at the new crew member. The attitude was that " he is learning . He will get better." The attitude was very professional. I have used Waterfront for about 10 years and use them for both pressure washing and windows.
