Ask the right questions so you can "offer" (not upsell) the right services. Proper expectations for the client, from sales to production, is highly relevant (e.g. "jobs like this usually have unforseen Rot/issues that can range from an additional $200-$800). (1) You can't sell what you don't offer. (2) Customers often need to be disarmed before they budge from what they originally tell you (3) offer more in depth inspections (attic/basement inspections, 24 pt. exterior inspections, etc.) to better diagnose those costs so you don't have change orders mid project.
