Verify the caller, then normalize every proposal

DECISION GUIDE 44

Make the next action fit the evidence

Use the condition described here to narrow the first safe action, the responsible contact, and the written authorization.

Do not pay for certainty that the observable pattern does not support.

OBSERVE

Preserve the useful clues

Ask for the legal contracting name and license number, then use CSLB’s current official record. Compare written proposals against the same evidence, access, material, permit, testing, and restoration assumptions.

Write the time, fixture, room, and use that preceded the change.
Photograph the wider context before taking a detail view.
Keep model labels, bills, prior repair records, and test results together.

CONTAIN

Choose the safe boundary

Do not treat call routing, a logo, vehicle, directory profile, or someone else’s license number as proof of the contracting entity. Keep sensitive details until identity is clear.

Containment should reduce harm without erasing evidence or transferring risk to gas, electricity, wastewater, finishes, or utility equipment.

AUTHORIZE

Put the first scope in writing

Require legal name, license, work and exclusions, materials, price and payment, permit duty, dates, access, protection, change process, test, cleanup, warranty, and closeout documents.

Ask what is included, excluded, and still unknown.
Set the price or authorization boundary before work expands.
Define the test or record that will show completion.
