If you suspect a plumber of overcharging you, particularly one from Quality Plumbing in Azusa, here are some indicators that might suggest dishonesty: 1. Not providing clear, detailed, or written estimates: A reputable plumber will lay out in writing (that's right, not just verbally) the cost of labor, parts, and any other work-related expenses. If they can't do this, or if they're giving you the runaround, that's cause for concern.High-pressure tactics can be a red flag. If a plumber pressures you to make immediate decisions or insists on doing extensive repairs and doesn't clearly explain why they need to be done, take a moment to consider your options and, if necessary, get a trusted friend or family member to help you think through the decision. A professional worth your time and money will do exactly that and will also give you time to come to a decision without resorting to underhanded methods.4. Not Enough Licensing and Insurance: Verify the plumber has both a license and insurance. In Azusa, as elsewhere, a license means the plumber meets certain basic standards, and insurance means you won't be stuck paying for accidents that might happen while the plumber is working in your home.5. Ineffective Communication: Communication is everything. If the plumber is unclear about the work being completed and the costs associated with it—or if the plumber is just plain hard to understand—look out. These could be signs of a failing plumbing business.6. Demands for Full Payment: Although it is standard to pay a deposit, be wary if your plumber asks for full payment before the job passes your inspection. If you remain vigilant for these signs, you are less likely to get scammed, subbed out, or overcharged.
