Start with evidence, not assumptions.
Tile and grout do not age in the same way. Material identification and a small compatibility test should come before broad cleaning.

Choose the pathway
Cleaning can address compatible surface soil and residue. Etching, failed grout, loose tiles or active leaks need repair or trade investigation.. Method and exclusions are confirmed after assessment.
Check completion
Readiness, drying or finish quality must be checked against the agreed scope rather than assumed from appearance.

Preparation and limitations
Identify known coatings or sealers, clear the floor and point out cracked joints, leaks or previous strong chemical use. Allow drying, use compatible maintenance products and address moisture sources before considering sealing.. Clear access, identify fragile adjoining finishes and disclose prior coatings, chemicals, leaks or repairs.
Hidden defects can change the scope after removal, testing or initial preparation. A quote must distinguish inspection findings, included work, exclusions and the next trade handoff.

Cleaning can address compatible surface soil and residue. Etching, failed grout, loose tiles or active leaks need repair or trade investigation. The reliable next step depends on the site condition and a written scope.
What should be checked before work starts?
Before work starts, Identify known coatings or sealers, clear the floor and point out cracked joints, leaks or previous strong chemical use. After service, Allow drying, use compatible maintenance products and address moisture sources before considering sealing.
Can the final method be confirmed from photos alone?
Photos help with triage, but moisture, bond, contamination, depth or movement may require on-site testing before a reliable scope is issued.
