The research question
We started with one question, scaled across 33 trades:
What does a homeowner actually need to know before hiring this trade — that they don't already know, that the tradie won't volunteer, and that the regulator already requires?
Every editorial decision flows from that question. If a fact is already common knowledge ("plumbers fix leaks"), we don't include it. If it's information the tradie's own quote would tell you ("we'll bring our own tools"), we don't include it. We include the gap — the things that determine whether the work is legal, lasting, and worth the money.
