Why plumbing businesses are different
Generic valuation tools miss what actually drives value in this vertical. AcquireLens scores these factors explicitly.
Emergency service revenue
Emergency calls carry premium pricing but arrive unpredictably, which changes how trailing revenue should be normalized.
Residential vs commercial mix
Commercial and multi-family work brings longer payment cycles, retainage, and different margin structure than residential service.
Recurring maintenance
Drain, backflow, and inspection programs create the recurring layer that separates a premium plumbing business from a service shop.
Truck fleet
Stocked service trucks are working capital on wheels — inventory, tooling, and replacement schedules all affect real cash flow.
Licensing
Master-plumber licensing is often tied to an individual, making license transferability a gating diligence item.
Water restoration
Restoration and mitigation revenue is insurance-dependent and must be assessed separately from core plumbing earnings.
Customer retention
Repeat homeowner and property-manager relationships determine lead cost and the durability of organic demand.
Dispatch and on-call load
After-hours coverage economics decide whether emergency revenue is genuinely profitable or subsidized by overtime.

Business valuation factors
Each factor is evaluated in sequence, and every adjustment to the multiple is documented in the final report.
- 1
Revenue quality
Service, emergency, restoration, and new-construction revenue are separated before any multiple is applied.
- 2
Recurring revenue
Inspection, backflow, and maintenance program revenue is isolated and tested for renewal behavior.
- 3
Service agreements
Property-manager and multi-family agreements are reviewed for term, pricing, and transferability.
- 4
Licensing and compliance
Master-license dependency, permit history, and code-compliance record are scored as transition risk.
- 5
Owner dependence
Estimating, bidding, and key-account relationships held personally by the owner reduce the defensible multiple.
- 6
Working capital
Truck inventory, retainage on commercial work, and receivable aging define the working-capital peg.
- 7
Equipment condition
Jetters, camera rigs, and van build-outs are scored for remaining useful life and near-term replacement cost.

Lower is better
AI recommendation
Attractive with conditions. The earnings base supports a defensible multiple, but concentration and owner-dependence testing should drive final pricing.
