Proof and risk boundary
A maintenance plan still needs job-specific evidence checks.
The right provider depends on the surface, access height, public-use risk, document requirements, and whether the work is cleaning, treatment, clearing, repair, or replacement. Keep those boundaries visible before comparing quotes.
Ask whether examples show a similar commercial surface, height, staining type, and public-access setting.
Separate provider-supplied photos, directory claims, and documents from evidence WashMerit has actually reviewed.
Confirm live insurance dates, RAMS needs, water and drainage controls, and who signs off completion before work starts.
Keep cleaning, clearing, treatment, repair, replacement, and specialist access work in separate scope lines.
