Pricing & Estimating

Service Rate Structure

Service Type	Typical Range	Notes
Service call / diagnostic	$75–$150	Covers truck roll + first 30 min
Hourly labor (residential)	$90–$180/hr	Varies by market, license level
Hourly labor (commercial)	$120–$250/hr	Prevailing wage on public jobs
Flat-rate residential	Per task book	Standardize with flat-rate pricing manual
Emergency / after-hours	1.5x–2x standard	Minimum charge $200–$350
Drain cleaning (basic)	$150–$350	Snake or hydro-jet upsell
Water heater install	$1,200–$3,500	Tank; tankless $2,500–$5,500
Repipe (whole house)	$4,500–$15,000+	Copper vs PEX, access difficulty
Sewer line replacement	$3,000–$25,000	Trenchless vs traditional
Backflow testing	$75–$250	Annual certification required

Markup & Margin Targets

Materials markup: 30–50% over cost (higher on specialty fittings)
Target gross margin: 55–65% on service, 35–45% on new construction
Net profit target: 12–20% after overhead
Flat-rate advantage: Customers prefer known price. Build flat-rate book with labor + materials + margin baked in.

Estimating Commercial Work

Takeoff from blueprints — count fixtures, linear feet of pipe, connection points
Labor hours = fixture count × labor units (use PHCC or MCAA labor tables)
Materials at contractor pricing + 25–40% markup
Add permits, inspections, equipment rental, subcontractors
Overhead allocation: 15–25% of direct costs
Profit margin: 10–20% depending on competition and relationship

Dispatching & Scheduling

Daily Operations

Morning huddle: 10 min max. Review board, flag callbacks, assign emergency slots.
Dispatch priority: Emergency → scheduled service → estimates → new construction
Service windows: 2-hour windows (8-10, 10-12, 12-2, 2-4). Never promise exact times.
Drive time: Max 30 min between jobs. Zone-based dispatching saves 15–25% fuel costs.
Callback slots: Reserve 1–2 slots daily for warranty/redo work.

Tech Utilization

Target: 75–85% billable hours per tech per day (6–6.8 hrs of an 8-hr day)
Track: revenue per tech per day, average ticket, callback rate
Top performers: $1,500–$3,000+ revenue per day

Software Stack

Field service: ServiceTitan, Housecall Pro, or Jobber
Dispatching: GPS fleet tracking (Verizon Connect, Samsara)
Invoicing: QuickBooks integration with field service platform
Customer communication: Automated text/email confirmations, on-my-way alerts

Licensing & Compliance

License Types (varies by state)

License	Requirements	Scope
Apprentice	Registered, supervised	Work under journeyman/master
Journeyman	4–5 years + exam	Independent residential work
Master Plumber	2–4 years journeyman + exam	Pull permits, supervise, sign off
Contractor	Master license + business license	Bid and contract jobs

Key Compliance Areas

Permits: Required for new installs, repipes, water heater replacements, sewer work. Pulling permits = liability protection + upsell proof.
Code: International Plumbing Code (IPC) or Uniform Plumbing Code (UPC) depending on jurisdiction. Know which your state/county adopts.
Backflow: Annual testing/reporting required by water authority. Certified testers needed.
EPA Lead-Safe: RRP Rule for pre-1978 buildings. $37K+ fines for violations.
OSHA: Trench safety (competent person required), confined space entry for sewer work, PPE.
Insurance minimums: General liability $1M/$2M, workers comp (mandatory in most states), commercial auto, tools/equipment floater.
Continuing education: 4–16 hours annually in most states for license renewal.

Inventory & Fleet

Truck Stock Standards

Every service truck should carry:

Fittings: Common sizes in copper, PEX, PVC, CPVC, ABS, cast iron (1/2" through 4")
Valves: Ball valves, gate valves, check valves, PRVs — residential sizes
Water heater parts: Thermocouples, gas valves, elements, anodes, T&P valves
Drain supplies: Cables (1/4" through 3/4"), cutters, auger heads
Fixtures: Faucet cartridges (top 10 brands), supply lines, angle stops, wax rings, flanges
Tools: Channel locks, basin wrench, tubing cutter, PEX crimp/expansion, soldering kit, camera (drain inspection)

Inventory Management

Par levels: Set min/max for every truck stock item. Reorder at min.
Weekly truck audit: 30 min per truck. Missing inventory = lost revenue.
Warehouse: Central warehouse for overflow, specialty items, water heaters.
Vendor accounts: Ferguson, Hajoca, local supply houses. Net-30 terms. Negotiate annually.
Shrinkage target: Under 2% of materials cost.

Fleet

Vehicle: Sprinter vans (preferred), box trucks for commercial, pickups for apprentices
Maintenance: PM schedule — oil, tires, brakes per mileage. Fleet downtime kills revenue.
Branding: Full vehicle wraps = 30,000–70,000 impressions per day per truck. Best ROI marketing.

Marketing & Lead Generation

Highest ROI Channels

Google Local Services Ads (LSA): Pay per lead, Google Guaranteed badge. #1 channel for most plumbers.
Google Business Profile: 5-star reviews drive calls. Ask every happy customer. Respond to all reviews.
SEO: "Plumber near me" + city pages. Long game but compounds.
Referral program: $50–$100 per referred job. Track and pay promptly.
Home service platforms: Angi, Thumbtack, Yelp — test each, track CPL.
Vehicle wraps: Passive brand awareness. Include phone number in huge font.
Repeat/maintenance agreements: Plumbing inspection + drain cleaning annual plan. $199–$399/year. Recurring revenue + first call rights.

Key Metrics

Cost per lead: Target $25–$75 residential, $50–$150 commercial
Booking rate: 75%+ of inbound calls should book

Common Mistakes

Hourly billing — You're leaving 20–40% on the table. Switch to flat-rate.
No call tracking — If you can't attribute leads to sources, you're wasting marketing budget.
Underpricing emergency work — After-hours is premium. Charge accordingly.
No maintenance agreements — Recurring revenue smooths seasonal dips and locks in customers.
Ignoring permits — Short-term gain, long-term liability nightmare.
Truck stock chaos — Every missing part = a return trip = lost revenue.
Not training techs on sales — Techs who can present options (good/better/best) double average tickets.
