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>

How much do plumbers typically charge?

<div><a href="https://www.angi.com/articles/plumber-cost.htm">The average cost to hire a plumber</a> is around $100 an hour but can vary between $45 and $200 an hour depending on the plumber’s experience and the repair that you need.

Edgar is the only plumber I trust for repairs, renovations, & upgrades in my home. His work is flawless, his prices are super competitive, and he does an excellent job explaining things to me in a way that a non-plumber like me can understand. MoCo Plumbing is my family's plumber for life.

I used Able Plumbing Inc today. It's not a new company. I have used them a lot in the past and they are the best plumber by far that I've ever used. It was $1400 but they gave me a discount. They are extremely competent and extremely pleasant to deal with.

After trying many other plumbers, my neighbor recommended Warren Gartrell of Gartrell plumbing. So, I made an appointment with Gartrell plumbing to repair a very slowly draining bath tub and a running toilet. These have been recurring problems, and other plumbers who have come have spent hours...

I like LEAHY PLUMBING and HEATING INC's persistence to get the job done. They kept working at it because it was really difficult. They have come on-time.

They contacted me right away and had a plumber out in just a few hours (and it wasn’t an emergency repair!). Tawn was very kind and professional and repaired the toilet quickly. Very happy with Day and Night Plumber and I’ve already scheduled an appt. with them for more work!

I have used them only once. They were very professional. He knew exactly what he was doing. He came in and did what he needed to do, put it together and was ready to go. The contractor I was using recommended them. He was very forthright so I clearly understood what he was saying.
