When a drain backs up or runs slowly, homeowners often ask: how much does it cost to unclog a drain? The answer varies based on location, the method used, and whether you hire a professional or attempt a DIY fix. Below is a practical overview to help you estimate expenses and choose the right approach.

Average price ranges

Most professional drain unclogging jobs include a diagnostic call and a service visit fee, typically between 50 and 100. If a plumber needs to use specialized equipment, such as a snaking tool or a hydro-jet, labor and parts can push the total to roughly 150 to 450 for a single drain. Additional charges may apply for multiple drains or if the clog is severe.

Common methods and their costs

DIY chemical drain cleaners are inexpensive, often under 20, but they may not solve stubborn clogs and can damage pipes in some cases. Professional methods include:

• Drain snake or auger: 100–250, effective for hair, grease, and small blockages.
• Hydro-jetting: 350–800, powerful cleaning that uses high-pressure water to clear buildup but is usually reserved for tough or recurring clogs.
• Camera inspection: 100–300 as part of diagnosing why the clog keeps returning.

Costs can increase if the clog is in a septic system, involves multiple lines, or requires pipe repair or replacement.

When to call a professional

If water backs up in more than one fixture, drains are slow across the home, or you notice foul odors, it may indicate a larger blockage or sewer line issue. A licensed plumber can assess the problem, identify root causes (such as tree roots or collapsed pipes), and advise on the best fix.

Tips to save on costs

Before calling a pro, try these cost-saving steps:

• Run hot water and use a plunger on minor sinks or tub clogs.
• Avoid repeated use of harsh chemical cleaners which can damage pipes and lead to costly repairs.
• Shop around for quotes and ask about diagnostic fees, crew size, and any after-hours charges.

Understanding the typical price ranges and available methods can help you weigh DIY options against professional service, reducing surprises at the checkout.
