Thanks SteTecs
Im only doing conservatory roofs on a couple of local homes. The maintenance manager for the local (who is one of my customers) said that the national that deals with them priced it at £30 per building for the windows and making a pants job of it. Think I'll get to price them over the next few months.
If thats one of the big boys, they wont be around long because the two homes that are local to me are massive-definately a good half days work
