Many plumbers either spend too little and stay stuck, or spend a lot on ads while missed calls quietly waste the money. This guide gives you a starting number, a way to build your own budget, the order to spend in, and how to check that every dollar is working.
Start With a Sanity Check
The U.S. Small Business Administration has suggested that small businesses with revenue under $5 million put 7 to 8% of revenue into marketing, assuming margins around 10 to 12% (SBA, archived).
| Your situation | Where you might land |
|---|---|
| Steady, strong repeat and referral work | Lower end |
| Growing, adding vans or plumbers | Higher end |
| New business or new area | Possibly above the range at first |
| Thin margins | Fix lost calls and follow-up before spending more |
Build Your Own Budget: Work Backwards
Step 1: Pull your numbers
From your job software or CRM, for the last 6 to 12 months:
- Average ticket for service calls and for big jobs (water heaters, sewer, repipes)
- Booking rate: booked jobs divided by leads
- Cost per lead by channel
- How many more jobs your team can handle
Step 2: Do the math
Example (made-up numbers): you want 30 more service calls a month and book 50% of leads, so you need 60 leads. If Local Services Ads leads cost about $50, that channel needs about $3,000. At an average ticket of $350, those 30 jobs bring about $10,500 in revenue.
Step 3: Think in customer value
Some service-call customers later need a water heater, sewer work or a repipe, and some become repeat customers. The real value of a new customer is often higher than the first invoice.
Spend in This Order
| Order | Fund this | Why |
|---|---|---|
| 1 | Answering every call, 24/7 if you offer it | Saves jobs you already paid for |
| 2 | Google profile and reviews | High-intent urgent calls at low cost |
| 3 | Website: service, emergency and town pages | Turns searches into calls |
| 4 | Local Services Ads | Paid leads at the top of Google |
| 5 | Search ads, partners, other channels | Extra reach once the base works |
A Sample Monthly Split
Example only for a small shop spending $3,500 a month.
| Item | Share | Example amount |
|---|---|---|
| Local Services Ads and search ads | 45% | $1,575 |
| SEO and website | 30% | $1,050 |
| Call handling, reviews and follow-up tools | 15% | $525 |
| Past-customer and partner marketing | 10% | $350 |
Time Your Spend
Plumbing is steadier than HVAC, but there are predictable spikes:
- Freezes in colder areas: raise budgets and on-call coverage before the first hard freeze.
- Heavy rain: sump pump and backup calls rise.
- Holidays: kitchen drain and disposal calls rise around big meals.
- March: the EPA’s Fix a Leak Week is a credible hook for leak inspection offers (EPA).
Judge Everything by Cost per Booked Job
| Metric | Formula |
|---|---|
| Cost per lead | Channel spend divided by leads |
| Booking rate | Booked jobs divided by leads |
| Cost per booked job | Channel spend divided by booked jobs |
| Return | Gross profit from those jobs divided by spend |
Use a tracking number for each channel and record the source of every booked job. Review monthly and move money toward the channels with the lowest cost per booked job.

How do I know my plumbing marketing is working?
