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 β€” count fixtures, linear feet of pipe, connection points 2. Labor hours = fixture count Γ— 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 β†’ scheduled service β†’ estimates β†’ 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 β€” 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 β€” 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

    1. Google Local Services Ads (LSA): Pay per lead, Google Guaranteed badge. #1 channel for most plumbers. 2. Google Business Profile: 5-star reviews drive calls. Ask every happy customer. Respond to all reviews. 3. SEO: "Plumber near me" + city pages. Long game but compounds. 4. Referral program: $50–$100 per referred job. Track and pay promptly. 5. Home service platforms: Angi, Thumbtack, Yelp β€” 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

  • Cost per lead: Target $25–$75 residential, $50–$150 commercial
  • Booking rate: 75%+ of inbound calls should book
  • Average ticket: Track weekly. Target steady increase via flat-rate and upsell training.
  • Customer acquisition cost: Under $200 for residential, under $500 for commercial

    • Growth Playbook

    Stage 1: Owner-Operator ($0–$300K)

  • You run every call. Focus on service speed and 5-star reviews.
  • Build flat-rate pricing book. Stop hourly billing.
  • Get 50+ Google reviews fast.
  • Systems: basic CRM, QuickBooks, Google Business Profile.

    • Stage 2: Small Team ($300K–$1M)

  • Hire first tech. Train on your flat-rate book + sales process.
  • Dedicated CSR/dispatcher (even part-time).
  • Systemize: truck stock, morning huddle, daily revenue targets.
  • Start LSA and SEO. Track every lead source.
  • Gross margin > 55% or you're pricing wrong.

    • Stage 3: Growth ($1M–$3M)

  • 3–6 techs. Dedicated dispatcher. Office manager.
  • Maintenance agreement program (500+ members = stability).
  • Add services: water treatment, gas lines, excavation.
  • Commercial contracts for recurring revenue.
  • KPI dashboard: revenue per tech, avg ticket, callback rate, CSR booking rate.

    • Stage 4: Scale ($3M–$10M+)

  • Department leads (service manager, install manager, commercial manager).
  • Apprenticeship pipeline β€” grow your own talent.
  • M&A: acquire retiring plumbers' customer bases.
  • Multi-location or expand service radius.
  • Private equity interest starts at $3M+ EBITDA.

    • Financial Benchmarks (Healthy Plumbing Company)

    | Metric | Target | |---|---| | Revenue per tech per year | $250K–$450K | | Gross margin (service) | 55–65% | | Gross margin (new construction) | 35–45% | | Net profit | 12–20% | | Labor cost (% of revenue) | 25–35% | | Materials cost (% of revenue) | 10–20% | | Marketing spend (% of revenue) | 5–10% | | Overhead (% of revenue) | 20–30% | | Callbacks / warranty (% of jobs) | Under 3% | | Tech utilization | 75–85% | | Maintenance agreement penetration | 25%+ of residential customers |

    Common Mistakes

    1. Hourly billing β€” You're leaving 20–40% on the table. Switch to flat-rate. 2. No call tracking β€” If you can't attribute leads to sources, you're wasting marketing budget. 3. Underpricing emergency work β€” After-hours is premium. Charge accordingly. 4. No maintenance agreements β€” Recurring revenue smooths seasonal dips and locks in customers. 5. Ignoring permits β€” Short-term gain, long-term liability nightmare. 6. Truck stock chaos β€” Every missing part = a return trip = lost revenue. 7. Not training techs on sales β€” Techs who can present options (good/better/best) double average tickets.
