Helpful information

The Sandison Service Process: what to know

The Sandison process moves from intake and safety screening to property and equipment identification, diagnosis, evidence, options, authorization, work, verification, documentation, maintenance, and follow-up.

Planning your next step

Questions about your property or service request?

Each stage preserves uncertainty and responsibility boundaries so a symptom is not presented as a confirmed cause, an option is not treated as authorization, and completion is not claimed before the agreed verification is performed. Call (248) 453-1227 during office hours or use the service-request form to discuss your situation.
