General Liability Insurance for Plumbers in Colorado: License Requirements and Coverage

Colorado plumbing contractors are licensed by the Colorado Department of Regulatory Agencies (DORA) under the Plumbing Program. A licensed plumber or plumbing contractor is required for plumbing work above defined thresholds, and licensing requires proof of GL insurance. Denver's growth and Colorado's mountain resort communities both generate significant plumbing work across residential and commercial markets.

Quick Answer

Estimated GL premiums for Colorado plumbing contractors:

Contractor Type	Annual GL Premium Range
Solo master plumber, residential	$1,400 to $3,200 per year
Small plumbing firm, 2-5 technicians	$2,800 to $6,500 per year
Commercial plumbing contractor	$6,000 to $16,000+ per year

Colorado plumber premiums are near the national average. Denver and mountain resort plumbers pay more than rural Colorado plumbers.

What GL Covers for Colorado Plumbers

Bodily Injury

Covers injury claims from clients and third parties arising from your plumbing work.

Property Damage

Covers damage your work causes to client and neighboring property:

• A pipe connection failure floods a Denver home or commercial building
• Excavation damages adjacent structures or utilities
• A mountain resort installation failure damages a high-value vacation property

Completed Operations

Covers post-completion claims. Colorado's 6-year statute of repose under CRS 13-80-104 defines the coverage window.

Products Liability

Covers claims from fixtures and materials you supply and install.

Colorado-Specific Considerations

DORA Plumbing License

Colorado DORA requires licensed plumbing contractors and proof of GL. Verify current requirements with DORA.

Mountain Resort High-Value Exposure

Colorado mountain resort clients have high-value properties. A plumbing failure in a Vail or Aspen vacation property can generate significant property damage claims. Adequate GL limits are more important for mountain resort work than standard residential work.

Altitude and Freeze Exposure

Colorado's altitude and winter temperatures create freeze risk for plumbing systems. Post-freeze repair work done under emergency conditions requires careful documentation of pre-existing damage.

6-Year Statute of Repose

CRS 13-80-104 provides 6 years from substantial completion. Maintain completed operations coverage for this period.

Workers Comp: No Minimum Threshold

Colorado requires workers comp from the first employee.
