Heya guys from circa 2010!! Re all of the possible hassles involved in pricing for,and hanging internal doors particularly.. plus all door furniture! And for the benefit of anyone out there thinking of hiring one of us talented and extremely humble Craftsmen to do the job for them...Depending on the honesty and ability of the carpenter in question, and the inevitable variables involved, even with new door frames... Talking with the client and explaining the possible scenario in detail, taking into account the variables... Is paramount!! I've made a name for myself over the all too numerous years that I've been professional multi-trade (...and that definitely ain't " handyman!"), by walking customers through the job at hand, then explaining that prices are flexible, depending on what's involved. My own rate for hanging an internal door (...Fire check doors apart which are obviously going to cost more, labour-wise!), starts at £50/door,and that includes all door furniture. Any idiosyncrasies with the frame,or the newly purchased door,then of course the time involved increases, and thus also the labour cost involved. Hope you've all stayed with me during this somewhat overlong missive... And happy chippying y'all... Over and out,probably... Cheers!
