HouseProFinder takeawayUse the diagnosis and written scope to compare options. For safety-sensitive work, rely on appropriately qualified professionals and local requirements.

Pressure before explanation

Be cautious when you are pushed to approve substantial work immediately without a clear diagnosis, scope or opportunity to ask questions, except where an urgent safety condition genuinely requires action.

Vague scope or verbal-only promises

Important details should appear in the written proposal or contract. If a promise affects your decision, ask for it in writing.

Unclear business identity

You should be able to identify who you are contracting with, how to contact them, and what licensing, registration or insurance applies where required.

Large unexplained changes

Projects can uncover hidden conditions, but additions should be documented. Ask for the reason, scope and price of changes before authorizing them when practical.

One red flag is context, not a verdict

Requirements differ by trade and location. The goal is to slow down, verify information and make a decision based on documented scope and qualifications.
