1. Document and hold the line
Note symptoms, prevent any further damage where that’s reasonably possible, and gather relevant history on the space.
2. Look at the house and the site
What actually holds up over time happens behind the tile — drain placement, framing, waterproofing transitions, ventilation, wiring capacity, and access all drive the real scope.
3. Put the scope in writing
Spell out preparation, protection, materials, access, permits, testing, cleanup, finish restoration, exclusions, and how changes get priced.
4. Compare more than the bottom line
Check credentials, then compare the reasoning and boundaries behind each proposal — not just the total at the bottom.
5. Confirm closeout
Testing, cleanup, documentation, warranty terms, and any ongoing maintenance responsibilities should all be confirmed before calling it done.
