1. Document, then protect
Record the symptoms, limit further damage where that’s reasonably possible, and pull together relevant history.
2. Evaluate the house and the site
What decides whether a bathroom holds up is out of sight: drain placement, framing, waterproofing transitions, ventilation, electrical capacity, and access all shape the real scope of the job.
3. Put it in writing
Spell out preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and how changes get priced.
4. Compare the reasoning, not just the number
Verify credentials, then compare how each proposal explains its own scope and boundaries — the total alone doesn’t tell you much.
5. Check the closeout
Testing, cleanup, documentation, warranty terms, and any ongoing maintenance responsibilities should all be confirmed before it’s considered done.
