Yes but the over roof window is a benefit.
The only benefit his leaflet lists is cleaning the frames and sills.
I could live with that, different approach, simplicity and all that. I don't like the reliable fully insured pro stuff myself as it's self referencing (I use the word pro as a fact, and have a pic of me that shouts reliable friendly and honest without having to say it)
I'm all for benefits. If he were to go the benefit route then 8wks is a huge benefit to larger property owners and fits his existing approach.
The classical approach to leaflets is to decide on a leaflet hierachy, and pick the most important benefits. He bypassed this and went for services, i'm not sure to what degree you can mix the two and retain clarity.
