Film the drill rig, never the report it produces
In limestone country a geotechnical investigation is an ordinary step on a residential pool, and it is the most persuasive thing you will ever put on camera, provided you stop at the equipment.
A rig taking borings in a Wesley Chapel or Lutz backyard tells a buyer you take the ground seriously before you take a deposit. Almost nobody in this metro films it, which is why it works.
What you may show: the rig, the crew, the sample tubes coming up, a plain explanation of what an engineer is looking for and how an answer changes a design or a price.
What you may never show: the report, the findings, the address, or any statement about what was found under a particular house. That document belongs to your client, and around this bay it can matter to an insurer and to a future sale of the property.
The value is in the sequence rather than the verdict. Show that an investigation happened, that a design changed because of it, and that the price moved with the design. A buyer who has watched that once understands why a real quote here arrives after the borings and not before.
