Two questions on the first call separate a whole house from one stuck door
The first ninety seconds should establish opening count and the age of the house, because everything downstream depends on both.
Opening count decides whether an in-home measure pays. Fourteen openings justifies the drive from your yard to almost anywhere in the Metroplex. One patio door in another county usually does not, and pretending otherwise is how estimators lose days.
House age tells you the product path before anyone quotes. A house from the mid-century core means non-standard openings, matching questions and slower work. A house from the growth years in Frisco or McKinney usually means failed seals in builder units and a faster path to a whole-house number.
Write both into the intake script as the first two questions, and make sure whoever answers the phone knows why. A script that reads like an interrogation loses people; two questions asked conversationally do not.
Add a third question for anything that sounds structural. If the complaint is a door that suddenly stopped latching or a gap that opened at a corner, note it before booking, because that appointment needs a different conversation and sometimes a referral to a licensed engineer rather than a sale.
