Texas TDLR Insurance Requirements for Plumbers
TDLR GL Requirement
$300,000 per occurrence minimum — for plumbing company registration
Workers' Comp
NOT mandatory in Texas — but strongly recommended for liability protection
Monthly Cost Range
$80–$500/month depending on crew size, revenue, and coverage package
License Required
Master Plumber License (individual) + Plumbing Company Registration (business)
Coverage Texas Plumbing Businesses Need
General Liability ($300K minimum)
TDLR-required. Covers water damage to client property, injury to customers, and completed operations liability (damage discovered after work is done). Water damage from plumbing errors is the #1 large-dollar claim for TX plumbers — the average flooded kitchen or bathroom water damage claim exceeds $15,000.
Commercial Auto
Required by most commercial clients. Your service truck is your mobile business — personal auto excludes commercial use. Commercial auto covers the vehicle AND tools in transit. TX Commercial auto minimums align with state liability standards ($30K/$60K/$25K) but most contractors carry $100K/$300K/$100K.
Inland Marine / Tools & Equipment
Covers your pipe cameras, drain augers, hydro-jet equipment, and specialty tools wherever they go. Standard GL does not cover your own equipment. A high-end drain camera ($8,000–$15,000) stolen from your van overnight is an inland marine claim, not GL.
Workers' Compensation
Not mandatory in Texas, but strongly recommended. Large commercial clients (apartment complexes, builders, property management companies) routinely require proof of WC before allowing your crew on site. Non-subscriber employers lose tort defenses and can face unlimited employee lawsuits.

🔧 Texas Plumber Pro Tip
Water damage from plumbing errors is the most common large-dollar GL claim for TX plumbers. Before doing any job that involves cutting into walls, floors, or ceilings, photograph the pre-existing condition of the work area. Document pipe condition before repairs. This documentation is your defense against inflated damage claims. Report any accidental water release to your carrier immediately — never make out-of-pocket payments without carrier involvement.
