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

1. Takeoff from blueprints — count fixtures, linear feet of pipe, connection points

2. Labor hours = fixture count × labor units (use PHCC or MCAA labor tables)

3. Materials at contractor pricing + 25–40% markup

4. Add permits, inspections, equipment rental, subcontractors

5. Overhead allocation: 15–25% of direct costs

6. 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

4. **Referral program:** $50–$100 per referred job. Track and pay promptly.

5. **Home service platforms:** Angi, Thumbtack, Yelp — test each, track CPL.

6. **Vehicle wraps:** Passive brand awareness. Include phone number in huge font.

7. **Repeat/maintenance agreements:** Plumbing inspection + drain cleaning annual plan. $199–$399/year. Recurring revenue + first call rights.

Key Metrics

**Booking rate:** 75%+ of inbound calls should book

**Average ticket:** Track weekly. Target steady increase via flat-rate and upsell training.

Common Mistakes

1. **Hourly billing** — You're leaving 20–40% on the table. Switch to flat-rate.

2. **No call tracking** — If you can't attribute leads to sources, you're wasting marketing budget.

3. **Underpricing emergency work** — After-hours is premium. Charge accordingly.

4. **No maintenance agreements** — Recurring revenue smooths seasonal dips and locks in customers.

5. **Ignoring permits** — Short-term gain, long-term liability nightmare.

6. **Truck stock chaos** — Every missing part = a return trip = lost revenue.

7. **Not training techs on sales** — Techs who can present options (good/better/best) double average tickets.
