How Much to Unclog a Drain? Average Costs Explained

A slow-draining sink or an overflowing toilet can disrupt your entire day. When home remedies fail, your next question is likely about the price: How much does it actually cost to unclog a drain?

On average, professional drain clearing ranges between $150 and $450, with most standard residential jobs landing right around $240 to $250.However, depending on the clog’s severity, location, and the equipment required, costs can range anywhere from $100 to $800 or more.

Knowing what drives these prices helps you make informed decisions and avoid unexpected surprises when the bill arrives.

Average Costs by Drain Location

The cost to clear a blockage largely depends on where the problem sits in your plumbing system. Fixture-level clogs are generally straightforward, while main lines require specialized intervention.

Drain Location	Common Causes	Average Cost Range
Bathroom Sink & Shower	Hair, soap scum, toothpaste buildup	$100 – $225
Kitchen Sink	Cooking grease, food particles, soap residue	$110 – $225
Toilet	Excess paper, wipes, foreign objects	$110 – $275
Basement / Floor Drain	Sediment, laundry lint, ground runoff	$150 – $400
Main Sewer Line	Tree root intrusion, heavy grease, collapsed pipe	$200 – $800+

Breakdown by Clearing Method

Plumbers use different tools depending on how stubborn the blockage is:

• Basic Hand Snaking ($100 – $175): Best for simple, localized clogs near the fixture opening, such as hair caught in a bathroom trap.
• Motorized Machine Snaking ($150 – $275): Uses a powered steel cable to punch through moderate blockages deeper in your interior pipes.
• Video Camera Inspection ($150 – $350): Feeds a high-definition, waterproof camera into the pipe to visually locate severe or recurring blockages.

When routine snaking isn’t enough, advanced equipment is necessary:

• Hydro Jetting Services ($250 – $800): For heavy grease buildup, scale, or intrusive tree roots, high-pressure water streams scour pipe walls completely clean. This method doesn’t just punch a hole through the clog—it restores the inner diameter of your pipes to near-new condition.

Factors That Influence Your Final Bill

1. Severity and Depth: A clog located 3 feet from your sink drain is faster and cheaper to clear than a obstruction 50 feet out in your sewer main.
2. Emergency vs. Standard Scheduling:After-hours, weekend, or holiday service calls typically add an emergency surcharge of $50 to $300 on top of standard labor.
3. Pipe Condition and Hidden Damage: If clearing the drain reveals cracked, sagging, or collapsed lines, specialized Leak Detection and pipe repair may be necessary to resolve the root cause permanently.

Beyond Drains: Protecting Your Home’s Plumbing System

It’s easy to focus on drains, but unresolved plumbing issues often impact other fixtures. For instance, severe pressure fluctuations or secondary backups can strain appliance lines. If you notice leaks near your water heater or inconsistent heating performance during an outage, professional Water Heater Repair ensures your hot water system operates safely alongside clean drains.

When DIY plungers and baking soda fall short, taking timely action saves money by preventing widespread water damage.
