Every call should end with three facts and a date on the calendar
An intake call that produces a name and a callback promise has produced nothing.
Write down the address, the covering and whether water is coming in right now. Those three facts decide who goes, what they bring and how urgent the visit is.
Then get a date. Not a promise to call back with a date. A specific window, confirmed by text before the call ends, because a scheduled appointment survives a competitor's phone call and a vague promise does not.
Give whoever answers a script with the questions in order and the honest answers to the two objections that come up every time: when can you come, and what will it cost to look. If the answer to the second one is nothing, say so early.
Assign the call. In small companies the phone belongs to whoever is nearest, which means it belongs to nobody. One person owns intake during working hours and a monitored service owns it outside them.
