A quote is given by whoever answered the phone and the work is done by whoever is free that fortnight. That is normal in this trade and it is the single most common thing people are unhappy about afterwards, so here is the crew, by name, before you decide anything.
Tom
Owner · quotes
The one who came and measured, and the one you ring. On site for the first morning, the last afternoon, and roughly half the days in between.
If you want something changed, tell Tom rather than whoever is nearest. It stops two people getting two different answers.
Wiremu
Leading hand · every day
On site all eleven days and the one running them. Wiremu decides the order things happen in and will tell you at the time if something behind a skirting board changes the plan.
Anahera
Painter · days 2 to 10
Second painter, in from the first preparation day to the last coat. Not on site on days one and eleven, which are moving days and only need two people.
Nobody else comes into the house. No subcontractors on a job this size, no apprentice you have not been told about, and no fourth person turning up on a Tuesday. If that ever has to change — somebody sick, somebody away — you get the name the day before, not on the morning.
