You don't fight the comparison — you define it. “We're getting other estimates” only beats you if the estimates get compared on the one dimension where you're weakest by default: a bare number attached to an undefined scope. The step-by-step: welcome it, discover what they're actually comparing, get their criteria stated in their words, and leave them a standard your proposal was built to meet.
The short answer
How it runs
You will not be in the room when the other numbers land, which is why the criteria step matters more than any rebuttal: a homeowner comparing bids against criteria they stated, that your presentation answered point by point is running your close for you. The inferior-sample work from the presentation pays off here too — hands that have felt construction differences read spec sheets differently. The full objection page carries the documented word-track; this guide is the framework sequence underneath it.
