What actually
clears a drain

If you're going to pay someone, it helps to know what you're paying for. The three main services solve different problems and cost very different amounts.

Snaking — the default

A flexible metal cable is fed down the line and rotated. Depending on the head fitted, it either punches through the blockage, hooks material out, or cuts through roots.

Good for: most single-fixture blockages, root intrusion, restoring flow quickly.

The limitation: a snake makes a hole through a blockage. It doesn't clean the pipe. If the line is coated in grease, a snake bores a channel through it and flow returns — but the coating remains, and it closes again.

That's why some blockages recur a few months after a clearance. Nothing went wrong; the service just wasn't the one that removes build-up.

Hydro-jetting — the thorough option

High-pressure water, typically through a rear-facing nozzle that pulls itself along the pipe, scouring the full internal diameter.

Good for: grease-coated kitchen lines, accumulated sludge, recurring blockages, restoring a line to something close to its original bore.

Camera inspection — the diagnosis

A camera on a flexible rod, fed down the line, usually with a locator so the position of a problem can be marked on the ground above.

Worth paying for when:

• The same blockage has recurred two or more times
• You're being quoted for excavation and want to see why
• You're buying an older property
• Nobody can explain why it keeps happening

The value isn't the video. It's that it converts "we'll clear it again and see" into a known problem you can plan around — roots that need cutting annually, a bellied section that will keep collecting, a crack that needs relining.

Rough costs

Service	Typical range
Basic fixture clearance	$150–300
Main line snaking	$250–600
Hydro-jetting	$400–900
Camera inspection	$200–500, often credited against repair
Spot repair	$1,000–4,000
Line replacement	$4,000–20,000+

Regional variation is wide and emergency call-outs cost more. Treat these as orientation.

Questions worth asking before work starts

1. "Is the call-out fee separate from the work?" Sometimes it's credited, sometimes it isn't.
2. "Is that a quote or an estimate?" A quote is a price. An estimate is a guess that can move.
3. "What happens if you can't clear it?" Establish this before, not after.
4. "Can you show me what's causing it?" If they've cameraed, they can.
5. "Is there a warranty on the clearance?" Many offer 30 to 90 days.

Signs of a bad job

• Quoting excavation without inspecting the line first
• Refusing to explain the cause
• Pressure to decide immediately on a large repair
• A price that changes substantially once work has started
• No written documentation of what was done

Emergency plumbing attracts this because customers are stressed and comparing prices is hard at midnight. Knowing the three service types and roughly what they cost is most of the protection you need.
