Early in the winter our sky light in our living room (cathedral ceiling) was leaking during a driving rain. I received a call back within one day, when it was viewable (weather started to get wintery right away) we got an inspection and a quote. They ordered the replacement part, and then we waited for weather to clear. As soon as possible, the window was repaired - and our other two sky lights inspected and cleaned. The only evidence that they were there is the clean sky lights and the repair.
