How to price plumbing services: A guide to profitable pricing

Most plumbers who underprice set their rates by copying the competition or by keeping the rates they charged five years ago, and neither accounts for their actual costs. The gap adds up fast: charging $75 an hour instead of $100 on a 5-hour job loses $125, and over 250 jobs a year that's $31,250 in lost revenue, enough for a new work van or a helper.

Your costs have three parts: fixed monthly costs (vehicle, insurance, software, tools, marketing, office, licenses and accounting, typically $2,000 to $4,000 a month for a solo plumber), variable costs on each job (materials, permits, dump fees, subcontractors and card fees), and your own salary. With a profit target, they set your minimum hourly rate.

Fixed costs (monthly)

Add up everything you pay regardless of how many jobs you do:

Typical monthly overhead for a solo plumber:$2,000–$4,000

Variable costs (per job)

• Materials and parts
• Permits
• Dump fees
• Subcontractor costs
• Credit card processing fees (typically 2.5–3%)

Your salary

Don't forget to pay yourself. What do you need to earn? What do you want to earn? Be honest and include benefits (health insurance, retirement) that a W-2 job would provide.

The hourly cost formula

(Annual overhead + annual salary + profit target) / billable hours per year

Example

Minimum hourly rate:$89/hour

That's your break-even-plus-profit rate. Anything less and you're subsidizing your customers.

Charge flat rates for residential service calls and common repairs and installations: customers approve a known price more readily, and you're rewarded for working fast. Charge hourly plus materials for diagnostics with an unknown scope, commercial contracts and maintenance agreements. Many plumbers use both, flat rates for common jobs and time and materials for unusual ones.

Hourly pricing (time and materials)

How it works: Charge by the hour plus materials with markup.

Best for

• Diagnostic work where you don't know the scope
• Commercial contracts
• Ongoing maintenance agreements

Drawback: Customers hate uncertainty. "It depends" is the least reassuring thing you can say.

Flat-rate pricing (recommended)

How it works: Set prices for specific jobs. The customer knows exactly what they'll pay before you start.

Best for

• Residential service calls
• Common repairs and installations
• Any job you've done enough times to estimate accurately

Advantages

• Customers feel confident approving work
• You're rewarded for being fast and efficient
• Easier for your team to sell

Hybrid approach

Many plumbers use flat rates for common jobs and switch to T&M for unusual or complex work. This gives you the best of both worlds.

A pricebook is a standardized list of every service you offer, each with a set price. Build it by timing each job type, multiplying by your hourly rate, adding materials with markup and a 15% to 25% profit margin, and rounding to a clean number. The sample below prices a 40 to 50 gallon water heater replacement at $1,099.

How to build one

1. List every job type you commonly perform
2. Time each one (average across multiple instances)
3. Calculate labor: Time × your hourly rate
4. Add materials: Typical parts needed with markup
5. Add profit margin: 15–25% depending on the job
6. Round to professional numbers: $397 feels better than $412

Material markup guidelines

Material markup is standard in plumbing. It covers your time sourcing parts, warranty risk, and inventory management.

• Small parts (fittings, valves): 50–100% markup
• Fixtures (faucets, toilets): 30–50% markup
• Equipment (water heaters, sump pumps): 25–40% markup
• Pipe and fittings (per job): 40–60% markup

Don't feel guilty about markup. Supply houses mark up materials before selling them to you, and you're adding value by selecting, transporting, and installing them.

Present pricing as three options (good, better and best), each with one specific all-in price, and say what it includes and when you can do the work. Use exact numbers rather than "about", and when a customer objects, point to what's included or to the cheaper option instead of discounting.

The Good-Better-Best method

Always offer three options when possible:

Example: Leaking Water Heater

Most customers choose the middle option. Your most profitable option should be "Better."

How to talk about price

Key principles:

• Use specific numbers (not "about" or "around")
• Bundle everything into the price
• Emphasize what's included
• Use "investment" instead of "cost"
• Close with timing

Handling objections

When a customer says it's too expensive:

1. Acknowledge: "I understand. It's an important decision."
2. Explain value: "The price includes [list everything]. You're covered for 10 years."
3. Offer options: "If budget is a concern, the standard option at $1,099 is a solid choice."
4. Never discount without removing scope

Raise your prices at least once a year, because your costs rise every year. At minimum, adjust for inflation (3% to 5%), update the material costs in your pricebook from your suppliers, and give existing maintenance customers 30 days' notice. If you haven't raised prices in two or more years, you've effectively given yourself a pay cut.

• Review annually: At minimum, adjust for inflation (3–5%)
• Give notice: 30 days for existing maintenance customers
• Adjust your pricebook: Update material costs from your suppliers
• Don't apologize: Professional businesses raise prices. It's expected.

Track five numbers to see whether your pricing produces a profit: gross margin per job (aim for 50% or higher), average ticket, tracked monthly, close rate on estimates (50% to 65% is healthy), revenue per billable hour against the hourly rate you calculated, and material costs as a share of revenue.

• Calculate your actual costs before setting any prices
• Flat-rate pricing is better for residential service in almost every case
• Build a pricebook and update it annually
• Always present Good-Better-Best options
• Mark up materials — it's standard and expected
• Raise your prices at least once a year
• Track profitability, not just revenue
