Can a cleaning, sanitizing, and drying company file a mechanics lien in California?

We are in the Property Restoration - Emergency Response Industry providing an array of services including but not limited to Water Mitigation. While the industry description of Water Mitigation Services can include properly cleaning, sanitizing, drying, repairing, and restoring a property to pre-water damage condition, many of our Mitigation jobs do not include restoration or repair. We generally invoice our repair services separately under a Structure Repair job invoice/ID. Our question is, for our California branches, are our Mitigation (cleaning, sanitizing, drying) balances eligible for the filing of a lien. We have been advised that these services/balances are ineligible because there are no materials provided that contribute to the repair of the property. Thank you for your assistance.
