Call a Professional Plumber

Hire a licensed plumber when DIY methods have not resolved the clog or when you suspect a deeper issue such as a damaged pipe, tree root intrusion, or a blockage beyond the branch drain. Expect to pay $100-300 for a standard drain clearing.

Why It Works

Plumbers use professional-grade tools -- motorized augers, hydro-jetting equipment, and drain cameras -- that reach further and apply far more force than consumer-grade products. A camera inspection can identify the root cause of recurring clogs, such as pipe corrosion, bellied pipe sections, or root infiltration, which no DIY method can fix.

Tips

• Call a plumber if the clog recurs within a few weeks of clearing; this signals a deeper problem
• Get a quote before work begins; most plumbers charge a flat fee for standard drain clearing
• Ask whether the quote includes a camera inspection, which is valuable for diagnosing chronic issues
• Verify the plumber is licensed and insured in your state
