How Much Should a Plumbing Company Spend on Ads?

Most advice on plumbing ad budgets starts with a percentage: spend this share of revenue on marketing. It is easy to remember and it answers the wrong question. A percentage tells you what you can afford in the abstract. It says nothing about whether that money will produce jobs, how many, or whether you could even handle them.

A better starting point is the one every plumbing owner already thinks in: jobs. How many more do you want each month, what is each one worth, and what would you happily pay to win one? Answer those and the budget falls out of the arithmetic.

Start from the jobs, not the percentage

You need four numbers. None of them come from an ad platform, and all of them are already in your invoices or your head.

• What a typical job is worth to you after materials and labour - gross profit, not the invoice total
• How many enquiries turn into booked jobs - out of every ten calls, how many do you book?
• How many extra jobs you could actually take on next month without letting anyone down
• How much of a job's profit you are willing to spend to win it, knowing some customers come back

The last one is a decision rather than a fact, and it is the one owners skip. If a customer is likely to call you again for the water heater, the drain and the next leak, you can afford to pay more for the first job than it earns on its own. If most work is one-off, you cannot.

A worked example

The numbers below are illustrative, not an industry benchmark - replace every one with your own. Say a typical repair earns you $225 in gross profit, and you are willing to spend a third of that to win a new customer: $75 per booked job. If you book one call in two, you can afford to pay $37.50 per call. Want twenty more jobs a month? That is forty calls, and forty calls at $37.50 is a budget of $1,500 a month.

Now check it against reality. If the searches in your area cost more than that per call, the answer is not to spend blindly - it is to raise the booking rate, target the higher-value jobs, or accept fewer extra jobs. And if you could only take ten more jobs, spending for twenty just buys calls you will miss.

The right budget is the one that buys the jobs you can handle at a price the job can carry. Everything else is either waste or missed work.

Emergency and planned work need separate budgets

A burst pipe at night and a water heater replacement next month are different searches with different economics. Emergency searches tend to cost more per click, but the people behind them book quickly and rarely shop around. Planned work is researched, compared and often quoted by three companies, but the jobs are larger.

Run both from one budget and the cheaper, faster-converting emergency traffic usually swallows it, leaving nothing for the jobs that grow the business. Splitting them - even roughly - lets you judge each on its own cost per booked job. It is one of the first things we set up in Google Ads for plumbers, because blended numbers hide which half is working.

Where the first dollars should go

For most plumbing companies, the first money belongs where people are already looking for a plumber: Google search, including Local Services Ads, which charge per lead rather than per click. Search captures intent that already exists, which is why it usually pays back fastest.

Your Google Business Profile costs time rather than media spend, and it decides whether you appear in the map for searches near you. Reviews, services listed properly and real photos do more there than any budget. If the profile is thin, fixing it is often the cheapest improvement available - see local SEO for plumbers for what that involves.

Social ads, display and anything aimed at people who are not yet looking for a plumber come later, once search is producing jobs at a price you are happy with. They have a place - reminding past customers, promoting maintenance plans - but they are rarely where a plumbing budget should start.

Signs you are spending too little - or too much

Too little looks like this: the ads stop showing by mid-afternoon because the daily budget runs out, and you are paying for calls only in the mornings. Google Ads reports this as impression share lost to budget, and it is worth checking before you decide ads do not work.

Too much looks different. Calls go to voicemail, callbacks happen the next day, and the booking rate falls as volume rises. The extra spend is buying calls the business cannot answer. The fix is not in the ad account; it is answering the phone, or spending less until you can.

• Check impression share lost to budget before raising or cutting spend
• Count unanswered and unreturned calls - each one was paid for
• Compare booking rate month to month as spend changes
• Judge everything on cost per booked job, never on cost per click

Give it long enough to mean something

A budget so small that it produces a handful of calls a month cannot tell you anything. One good week makes it look brilliant and one bad week makes it look useless. Whatever number you settle on, it needs to produce enough calls - a few dozen over the first couple of months - for the booking rate and cost per job to settle.

That is also the honest answer to whether a small budget can work. It can, if it is concentrated on the searches most likely to book and the calls are answered. Spread thinly across every service and every suburb, it rarely does. If you want help setting it up that way, that is what our plumbing marketing and lead generation for plumbers work is built around.
