A plain-English guide to running Facebook and Instagram ads for a plumbing business. What leads actually cost, which jobs pull, and how to avoid wasting your budget.
Short answer: yes, when they're set up right. Plumbing is a local, high-value, recurring-need service, which is exactly the kind of business Facebook and Instagram ads do well for. The catch is that most plumbers who "tried Facebook ads once" either boosted a post, ran the wrong kind of ad, or pulled the plug after a week. This guide walks through what actually works, in plain English, using the real numbers we see running trade campaigns in Australia.
Quick note on wording, because it trips a lot of tradies up. "Facebook ads", "Meta ads" and "Instagram ads" all run through the same platform, because Meta owns both Facebook and Instagram. When you run Meta ads for plumbers you're just choosing which of those feeds your ad shows in. Most plumber leads come from Facebook lead ads, the in-app enquiry forms we cover below, with Instagram adding a smaller share.
The honest answer is that cost per lead depends on your city and your offer, not just your trade. We haven't run enough plumbing-only campaigns to publish a plumber-specific number we'd stand behind. But plumbing sits in the same home-services band as electrical, and across the NSW trade campaigns we run, cost per lead has landed roughly between $14 in regional areas and $44 in Sydney, with most leads in the $20 to $40 range.
So a fair expectation for a plumber is to budget around $300 to $600 a month in ad spend to start, plus a management fee for someone to set up, run and optimise the campaigns. At roughly $30 a lead, $450 of ad spend is about 15 enquiries a month. Win one or two decent jobs off that and the maths works comfortably in your favour.
For the full breakdown of what leads cost across trades, see our guides on cost per lead for Sydney tradies and what Facebook ads cost for tradies. We also published the raw numbers from three real electrician campaigns in Facebook ads for electricians, and plumbing behaves much the same way.
Be wary of $5-lead promises. If an agency guarantees you plumbing leads at a few dollars each, they're usually counting page likes or low-intent clicks, not real enquiries. A genuine plumbing lead in a capital city sits in the tens of dollars, not single digits.
They do different jobs, and the right answer depends on the work you want more of.
Google Search catches demand that already exists. When someone's hot water system dies or a pipe bursts, they search "emergency plumber near me" and call the first few results. For urgent work, Google Search and a strong Google Business Profile are hard to beat, because the customer is ready to book right now.
Facebook creates demand. It puts your business in front of local homeowners who aren't searching yet but will need a plumber soon: the bathroom reno they keep putting off, the ageing hot water unit, the tap that's been dripping for months. The leads are cheaper, but you have to spark the interest with a good offer.
For most plumbers the smart play is both: a free, well-run Google Business Profile catching the urgent searches, and Facebook ads keeping a steady flow of planned and discretionary jobs coming in. We compare the two in Google Ads vs Facebook Ads.
Facebook shines for planned and discretionary work, the jobs people choose to do rather than emergencies. The strongest performers for plumbers tend to be:
Genuine emergencies like burst pipes, no water, or sewage lean more towards Google, because those customers are searching, not scrolling. Use Facebook to fill the calendar with the planned work between emergencies.
From running trade campaigns, the same handful of things separate ads that pull from ads that flop:
Lead form ads, almost every time, especially when you're starting out. A lead form is the in-app enquiry form that lets someone send their name, phone and a few details without leaving Facebook. They work because they remove friction: no waiting for a slow page to load, no hunting for a phone number, no typing out a full address. The customer taps the ad, confirms their pre-filled details, and you've got an enquiry.
In the trade campaigns we run, lead forms consistently beat traffic ads that send people to a website, and we've watched website-traffic ads burn through budget without producing a single enquiry. Traffic ads have their place for awareness and retargeting, but for a plumber generating enquiries on a sensible budget, start with lead forms.
Speed matters more than anything. A Facebook lead goes cold fast. Plumbers who call a new enquiry back within a few minutes book far more jobs than those who get to it that evening. Have a way to be alerted the moment a lead comes in.
Most trade campaigns start producing leads inside the first week, but the first 7 to 10 days are a learning phase while Facebook's algorithm works out who responds. Real optimisation kicks in from week two. The most common mistake we see is pulling the plug after five days and one lead. Give it four to six weeks before you judge it properly, and refresh the ad photo and offer if the cost per lead starts creeping up.
Here's the short version for a plumber thinking about Facebook ads:
Win one hot water replacement or bathroom job off a month of leads and the ads have usually paid for themselves several times over.
This is exactly what we do: Facebook and Instagram ads for plumbers, run for local plumbing businesses across Sydney, the Northern Beaches and beyond. Every campaign starts with a free quote and a plain English plan, no lock-in contract, no jargon.
