Should plumbers be certified or licensed?

<div>Yes, most states require plumbers to be licensed, and for good reason. Hiring an unlicensed plumber could lead to poor quality work, costly future expenses, and potential code violations. As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include: <ul><li>The owner, principal, or relevant manager passed a criminal background check</li><li>Required to have applicable state and local licenses</li><li>Maintain an average star rating of 3.0 or better on our network, if they have at least one review</li><li>Paying to advertise their services</li><li>Meeting any other eligibility criteria required by Angi</li></ul> Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.</div>

What questions should I ask a plumbing contractor?

<div>Before <a href="https://www.angi.com/articles/7-questions-ask-hiring-plumber.htm">finding the right plumber for your job</a>, there are a few questions that you should ask, including: <ul><li>Are you licensed and insured?</li><li>Do you charge for estimates? </li><li>Is your fee a flat rate, or is it hourly?</li><li>Who will do the work? Are they all licensed and qualified plumbers?</li><li>What happens if any breaks or damages occur?</li><li>What is your response time in an emergency? </li><li>Is cleanup included in the quote?</li><li>Do your services come with a guarantee?</li></ul>Discussing these questions with your plumbing contractor will help eliminate future issues and clarify expectations. </div>

Should I clean before the plumber comes?

<div>Before your plumber pays you a visit, it’s a good idea to clean up any boxes, garbage, or other obstacles that could be in their way. In addition, it’s best practice to clean the area that needs to be inspected or worked on, like a toilet, for example. Make sure to keep kids and pets out of the way once the plumber arrives.</div>

How much are typical plumbing repair costs?

<div>Typically, <a href="https://www.angi.com/articles/how-much-will-plumbing-repair-cost.htm">plumbing repairs cost</a> about $325 per job but can range from $175 to $4,000 or more. Simple fixes, such as a toilet repair, will be less expensive at around $150 to $400. However, if you have a pipe that has burst, you can expect to pay between $1,000 and $4,000 or more. The project that needs to be completed, the size of your home, and the type of plumbing pipes you have can all impact the final cost. External factors such as supply chain issues and shortage of materials all play a part in how much this repair might be.</div>

Sam was extremely professional and easy to work with. The plumber that came to do the work was punctual and professional. It was refreshing to find a plumber that is professional and reliable. We will use Graham's Plumbing again for any additional plumbing needs.

Plumber came late -- even though they requested via phone that I meet them 30 minutes prior to our agreed time. I rushed home only to get a later phone call that they would be coming later . . . with no time given. Plumber assessed the problem to be a frozen pipe, did not offer to thaw the pipe,...

Not happy with plumber. Was overcharged for labor. A friendly coworker was kind enough to apologized for mistake. Plumber seems defensive about plumbing questions? The office was very fair in not charging me for an extra visit.

It was okay. The problem is that he works another job so it takes him twice as long to do a job. He does the plumbing thing part time. So when he gets down at 5 o' clock he comes out to your house for three hours and does what he has to do. But we needed somebody little bit quicker than that. He...
