Long story short, my wife colleague's dad is a plumber so we got him to quote to remove/replace a shower screen. We didn't get a firm quote other than being told verbally it's going to be half a day. So the bloke turned up with an assistance, spent the whole day working on it and now being billed $960 ex for the whole job ($60/hr x 2 x 8 hours). Not to mention it was done fairly badly now the frame isn't aligned to how it supposed to be, cracked couple of my tiles (and begrudgingly repaired them in a shoddy manner) and all the sealants already started lifting off the surface. Anyway... 1. Does verbal quotation hold any weight? 2. He didn't mention he will be dragging someone else in to do the so how is it my problem he needed to get an assistant in to help? 3. Is $960 ex the going rate for remove and replace a shower screen/base? I suspect a letter on demand is on its way, thinking of settlement with him 4 hours x 2 x $60/hr given that's what he said verbally. Might goto NCAT as well if no joy in settle... Any advice? Yes lessons learned - will get a written quote (we do that normally, she just thought a colleague's father should be less shoddy than a random off the street bloke) and won't employ anyone who's remotely associated.
