Hiring a plumber can feel daunting, but knowing what to look for protects you from overcharges and substandard work.
Always verify the plumber holds a valid state license. In most states, you can check the contractor's license status online through the state contractor board. A license ensures the plumber has passed exams on local codes and safety standards.
Get at least three quotes before choosing. Pricing varies significantly between companies, and a detailed written estimate lets you compare apples to apples. Be wary of quotes dramatically lower than the others -- this can signal unlicensed work or hidden fees.
Ask about insurance. A plumber should carry both general liability (protects your property) and workers' compensation (covers injuries on the job). Request certificates of insurance before work begins.
Understand the pricing structure. Some plumbers charge a flat rate per job; others bill by the hour plus materials. For complex jobs, flat-rate pricing gives more predictability. For simple repairs, hourly may be cheaper.
Check reviews on Google, Yelp, and Angi. Look for patterns rather than outliers -- one bad review among dozens of positives is less concerning than consistent complaints about billing practices.
