Sinisco's team earned consistent praise for arriving quickly on emergencies (1.5 hours on a holiday) and working cleanly and professionally through extraction, drying, and repair. One older complaint flagged missed appointments and slow demolition start, though most reviews describe the opposite: fast service and smooth hand-offs to reconstruction phases.
