How Much Does It Cost to Clear a Blocked Drain in Sydney? (2026)

A brief look at the nonsense that plays out on Google search for blocked drain advertising in Sydney.

If you have ever searched for “blocked drain [insert your city]” you have probably seen ads promising to unblock your drain for less than $100. Wow! What a great deal. Too good to be true almost…

Spoiler alert… it is. Let me explain why, and why in 2026 the numbers are even more absurd.

Let’s do the maths

Let’s invent a hypothetical company, “Dodgy Brothers Plumbing Pty. Ltd.” or DBP for short. Let’s assume DBP pay their plumbers the lowest wage legally possible and have zero operating costs (no office, no insurance, no admin staff, no equipment servicing, etc.)

• Lowest award wage for a plumber in NSW (2026): $43 p/h (any decent plumber earns more than this, but let’s be generous to DBP)
• Cost for labour on travel time: 30 minutes each way = 1 hr @ $43
• Cost for petrol (2026 Sydney prices): Ute/van with a load, 18 L per 100 km of urban driving @ avg. 22 km (round trip) x $2.25 per litre = $8.91
• Avg. toll cost: 2 ways @ $8.50 = $17.00
• Avg. time to do the job: 1 hr @ $43 p/h = $43

Total out-of-pocket costs for DBP so far: $111.91

We’re already losing money, and Google surely didn’t give that lead for free. Let’s look at what Google Pay-Per-Click (PPC) ads cost plumbers in Sydney in 2026.

An average of $60+ per click for competitive blocked drain keywords in Sydney. That’s right, every time someone clicks one of these ads, DBP’s credit card gets debited around $60. In 2017 when we first wrote this article it was $40 per click. Fun times.

A tuned landing page with good copy and compelling ad headlines will attract a conversion rate of between 10 and 17%. That’s 10 to 17 phone calls for every 100 clicks, or in money terms:

Now where does that leave us?

They charge $69 for something that costs them $582? Are your spidey senses tingling yet? They should be. In 2017 the number was $411. In 2026 it’s $582. The ads have not kept pace with reality, which tells you everything you need to know.

And that’s not the half of it

We still haven’t added general overheads: plant and equipment repayments, maintenance, servicing, office rent, admin staff, public liability insurance, workers’ compensation insurance, employee entitlements, GST, accounting costs, equipment depreciation. The list goes on.

A plumbing business advertising on PPC needs to recoup operating and advertising expenses while still turning a profit, making those “$69 unblocked drain special” ads look pretty doubtful.

There are one of three things going on here

1. Sydney plumbing companies are the most charitable businesses on the planet
2. Sydney plumbers can’t read the ROI section of their marketing reports and are losing thousands every day
3. The industry is in a race to the bottom of dodgy “bait and switch” pricing tactics and everyone is copying each other

I’ll let you make your own mind up about which of the three is going on here. Nine years on from when we first wrote this, the answer seems increasingly obvious.

How does the “bait and switch” pricing work?

There are two ways these generally play out:

Both strategies have the same simple goal: get a foot in the customer’s door, then deliver the well-rehearsed sales pitch on a more expensive service, or wait to explain the full costs once on-site. Got to get those advertising dollars back somehow.

So what should you look for in a good blocked drain plumber?

Rather than keep calling out other companies, let’s talk about what the good ones are doing right:

• Realistic about costs (and preferably display them on their website)
• Include as many costs as they practically can in their advertised price (call-out costs, drain camera, etc.)
• Plumbers are happy and not required to deliver pushy, rehearsed sales pitches on every job
• No history of bulk online reviews from people who have only ever written one review
• Not targeting overly competitive PPC keywords (the numbers simply do not work in Sydney unless you plan to charge $700+ to unblock a drain)

It’s simple. And yet here we are in 2026 with the same ads, the same tricks, and the same disappointed customers wondering why their “$69 drain unblock” somehow turned into a $650 invoice.
