I completely agree with Bob. I have been cleaning windows wfp for 4.5 years, and have always done the frames, and doors for that matter (including garage, depending on type of door). The price I quote includes this, and that's what I tell my customers. I think it very strange not to do the frames, certainly if wfp, I mean why wouldn't you?, you would be using the same method. As for your price, I know this can vary quite a lot from area to area, and I don't know where you are based, but from what I learned from another forum, the prices I charge up here in north east Scotland, seemed to be at the higher end. I would be charging £10-£12 for a 3 bed semi, £15-£17 with conservatory.
