I'm NOT - but i did make it very clear before commencement of our bathroom and en-suite that i had a drawing to scale and expected to follow that drawing, unless a major issue and then discuss. I also asked to be kept informed and had a quick chat either 1st thing in morning or evening on that days plan etcAre clients "constantly watching" their plumber all day every day for weeks? Who has time for that and would that not appear very rude to be sitting on a chair watching them all day?
Pain, but otherwise you end with things like you have
i specified the types of isolating taps i wanted on the bath/basins/shower (they actually did not put an isolator on the shower line - so they end of that day - i had to ask why, and get them to fit one....
I know i can be a bit of a pain for trades - BUT i do explain that from the outset, when accepting the quote
So far I seem to have had good fitters for the electric, kitchen fitters , roof & facia soffet gutter , bathroom & en-suite refurbishment , general plumber .... and they are happy to change things as we go along, and also to explain what they are doing in if they have to deviate and why ..... but as i say I make that very clear from the outset .
i can imaging if in a full time job where leaving before they arrive and after they go - can be a problem , but my experience is you do need to be on top of this stuff, so not watching allday - but certainly involved daily.
I know in my old house when i had the facias and soffets all changed , i had to be away for most of the work - and it was a bit of a mess (NOT as we had discussed and i also had written down ..... copy was with them ) at the end, but i had held pack a big chunck of payment and they did come back and sort out. had i paid in full , would never have seen them again I suspect
