How Much Should a Plumbing Company Spend on Marketing? Benchmarks by Revenue Stage
"What should we spend on marketing?" is the most common question we hear from plumbing owners, and most answers they have gotten are either a shrug or a pitch. Here are the actual benchmarks, with the reasoning attached so you can adjust them to your situation instead of trusting ours.
The percentage bands
Marketing spend as a share of gross revenue, counting everything: ad spend, agency or staff costs, software, tracking tools.
| Stage | Spend | Who this is |
|---|---|---|
| Maintenance | 4 to 7 percent | Established shop, strong repeat base, defending position |
| Growth | 8 to 12 percent | Adding trucks, entering new service areas, building project pipeline |
| Launch | 12 to 15 percent | Under 3 years old, no repeat base yet, buying every first customer |
Two notes on the bands. First, below 4 percent is not really maintenance; customer attrition in the trades runs high enough that under-spenders shrink slowly and blame the market. Second, the launch band is not optional bravado. A new shop has no repeat revenue cushion, so nearly every job must be purchased, and the math only improves as the customer list grows.
Where the money goes, by stage
Launch ($500k to $1M revenue, spending $60k to $150k/year): The first dollars are capture infrastructure, not advertising. A fast site with tap-to-call and booking, Google Business Profile done properly, and a review-request habit cost little and multiply everything after. Then Local Services Ads for emergency volume, because pay-per-lead limits downside while you learn your numbers. Paid search comes last, once landing pages exist. At this stage skip: radio, billboards, sponsorships, and anything measured in "impressions".
Growth ($1M to $5M, spending $100k to $500k/year): This is where channel split starts to matter more than total. A typical high-performing allocation:
- 30 to 40 percent: Local Services Ads plus paid search on emergency and high-intent terms
- 20 to 25 percent: SEO, including the emergency visibility work and cost-guide content for project work
- 15 to 20 percent: retention (email to the customer base, maintenance plan promotion), which produces the cheapest revenue in the whole mix
- 10 to 15 percent: retargeting and project-pipeline nurture for big-ticket lines
- The remainder: tracking, software, creative
The channel-by-channel reasoning is in our ranked guide to plumbing leads; the short version is that emergency and project work need different investments, and shops that fund only the emergency side cap their ticket sizes permanently.
Scale ($5M+, spending $350k to $1M+/year): Totals grow but the interesting shifts are structural: dedicated budget for recruiting-adjacent brand work (trucks, community presence, sponsorships finally earn a slot because hiring is now the constraint), multi-location attribution, and a real analytics layer. At this stage the question stops being "how much" and becomes "what is our cost per booked job by channel by service line", and the operators who can answer it reallocate monthly and compound their advantage.
The two ratios that matter more than the percentage
Cost per booked job, by channel. Not cost per lead. A $70 LSA lead that books 60 percent of the time is a $117 booked job; a $25 aggregator lead that books 12 percent is a $208 booked job that three competitors are also calling. Owners who track only lead cost consistently fund the wrong channels.
Revenue per customer per year, including repeats. Marketing that acquires a customer who returns for a water heater in year two is buying an asset, not a job. This is why the retention slice of the budget, unglamorous as it is, usually posts the best return in the whole plan and why we push email programs before almost anything else.
The honest caveat about benchmarks
Every band above widens with metro competitiveness, service mix, and how good your capture is. A shop that answers 95 percent of calls can hit growth targets at 8 percent while a shop answering 70 percent burns 12 percent standing still, because a third of what marketing buys evaporates at the phone. Before raising any budget, read what missed calls actually cost and check your own answer rate. It is the cheapest budget increase available.

FAQ
What percentage of revenue should a plumbing company spend on marketing? Maintenance: 4 to 7 percent. Growth: 8 to 12 percent. New companies: 12 to 15 percent. Below 4 percent, attrition usually outpaces acquisition.
How much does a $3M plumbing company typically spend? Growth mode: $240,000 to $360,000 per year all-in. Maintenance: $120,000 to $200,000.
What should a new plumbing company spend first? Capture infrastructure (site, profile, reviews), then LSA, then paid search. Brand channels come much later.
Do agency fees count in the budget? Yes. Count spend, fees, software, and dedicated staff time, or your cost-per-job math breaks.
