1. Observe and protect
Record what’s happening, limit further damage where it’s safe to do so, and gather whatever history is relevant.
2. Evaluate the house and site
A sound diagnosis walks through how the fixture behaves, what it’s made of, current pressure and drainage, venting, shutoff locations, access, and any prior repairs on record.
3. Define a written scope
Spell out preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and change-order terms.
4. Compare providers
Check credentials, then compare the reasoning and boundaries behind each proposal — not just the bottom-line number.
5. Inspect closeout
Confirm the work was tested, the site was cleaned up, documentation was provided, and warranty and maintenance responsibilities are clear.
