If you're a plumber relying mostly on word of mouth and Google, Facebook & Instagram ads might sound like a lot of hassle for not much return. I thought the same thing for a long time. But after setting up campaigns for dozens of local service businesses, I can tell you: done right, Facebook & Instagram ads can be one of the most cost-effective ways to fill your schedule with paying customers.
Here's what actually works.
Why Facebook & Instagram ads work well for plumbers
Plumbing is an urgent, local need. When a pipe bursts at 11pm or a boiler stops working in January, people aren't browsing — they're searching. That's where Google ads traditionally win. But Facebook has a different, equally valuable use case: it lets you stay top of mind with homeowners in your area before they have a problem.
When someone sees your ad three times over a few weeks and then their kitchen tap starts leaking, you're the first person they think of. That brand recall, built cheaply through Facebook, is hard to replicate any other way as a local tradesperson.
Facebook also lets you reach people in specific life situations. Someone who just moved? Probably needs a plumber soon. Owns a home built before 1990? Likely dealing with aging pipes. These aren't targeting options you get on Google.
What a good plumbing ad actually looks like
I've seen plumbers spend €300 on ads that generate zero calls, and others spend €150 and book six jobs. The difference is almost always the creative — meaning the copy and the image.
The single biggest mistake is being too generic. "Local plumber, fast service, free quote" tells nobody anything they don't already know. Every plumber says that.
What actually converts is specificity and credibility:
- A real number: "Over 800 jobs completed in Manchester since 2018" builds trust instantly.
- A specific service: "Emergency boiler repairs — most jobs fixed same day" is far more compelling than "all plumbing services."
- A guarantee: "If we can't fix it, you don't pay" removes the risk that stops people from picking up the phone.
- A real photo: A photo of you or your van — not a stock image — outperforms professional visuals almost every time for local service businesses.
Keep the copy short. Three sentences max for the main body text. Your job is to get them to click or call, not to explain everything you do.
Who to target
For most plumbing businesses, the sweet spot is:
- Age: 30–55. Homeowners in this range are the most likely to have ongoing maintenance needs and the income to pay for quality work.
- Location: Set a radius of 10–20km around your base. Tighter if you're in a dense city, wider if you're in a rural area where jobs are spread further apart.
- Interests: Home improvement, DIY, property. These aren't perfect signals but they help Facebook find the right people faster in the early days of a campaign.
Don't bother splitting your targeting by gender. A/B testing demographics sounds smart but with a small budget it just spreads your money too thin and slows down the learning phase.
How much to spend
Start at €10–15 per day. This gives the Facebook algorithm enough data to learn who responds to your ad without burning through budget while it figures things out.
Give any new campaign at least two weeks before judging it. The first week is often slow as Facebook optimizes delivery. By week two you'll have a much clearer picture of what your cost per lead actually is.
Once you have a campaign that reliably brings in leads at a cost you're comfortable with, scale gradually — add €5/day every week or two rather than doubling overnight. Sudden large budget increases often reset the algorithm's learning phase and temporarily push your costs up.
The thing most plumbers don't do
Follow up fast. A Facebook lead is not the same as a phone call from someone with a burst pipe. They filled in a form or clicked through to your website. They're interested, but they haven't committed.
If you call a Facebook or Instagram lead within five minutes of them submitting, your chance of converting them is dramatically higher than if you call them an hour later. Most plumbers wait hours or don't call back at all. Set up a system — even just a phone notification when a new lead comes in — to make that call immediately.
If you're the one who calls in five minutes while everyone else calls in two hours, you'll win a disproportionate share of jobs with the same ad spend.
