We've had 3 upvc sash windows installed to replace rotting wooden ones. The window guy we used came personally recommended. We discussed spec and I explained i wanted the most authentic looking sash windows but we've got very obviously cheap alternatives. The edging is awful (see pic). You can see the grey brushes and there seems to be a lot of plastic trim stuck on. The ones i had seen and were hoping for are a complete unit. They definitely dont look authentic! I'm really annoyed as money is tight. We've only paid half of the money and he's actually yet to finish the installation (keeps cancelling last minute). How do I tackle this with him? I fear I wasn't specific enough in my spec (did show pics etc) but he doesn't work out a showroom etc so couldn't agree finishes that way. Ideally I want them replaced but am I asking too much?
