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>

We love Don. He shows up when he says he will. He put in pex lines plus he did some additional plumbing for a washing machine. He came back to do some plumbing work after a new vanity went in. Don is definitely our plumber of choice.

The job went good. He actually did it. I had a plumber come out before him and he said he couldn?t do it. He would have to knock a hole in the wall at the other end of the shower. I hired Holt and they did it a lot more efficient and got it done within three hours.
