What Makes a Great Denver Plumber
Top plumbers have: Colorado Master or Journeyman Plumber license (verify at dora.colorado.gov). 10+ years experience with Denver's older homes. $1M+ general liability and workers' comp insurance. Denver business license. A+ BBB rating with minimal complaints.
They provide upfront pricing, explain options clearly, pull permits when required, and offer warranties on labor (typically 1–2 years).
Red Flags to Avoid
Unlicensed 'handymen' doing plumbing work. No written estimate. Pressure to replace when repair is possible. Cash-only deals. Quotes 40%+ below competitors. No permit when required.
In Colorado, only licensed plumbers can perform plumbing work beyond basic repairs. Hiring unlicensed contractors voids insurance and creates liability.
How to Compare Plumbers
For non-emergency work, get 2–3 quotes. Compare: Diagnosis and recommended solution. Materials and brands. Permit costs (if applicable). Timeline. Labor warranty. Total cost.
Ask: What is your license number? (Verify it.) Do you offer a warranty on labor? Can you provide recent references? Are you insured? Do you charge a service call fee?
