"A first time apartment owner and landlord, I needed major plumbing services within the first 6 months of ownership. The first time was a series of gas leaks which were quickly repaired by Western Rooter. The second time was the significant work of adding 2 gas meters and the requisite task of re-routing/adding gas piping. I simply cannot recommend Daniel Westereng and Western Rooter enough. Although the owner John came out to assist in the final bid, Daniel and I worked consistently with SoCal Gas to coordinate the improvements. Daniel was quick to return texts, calls, e-mails and worked diligently with all the parties to get the job done. If you need a plumber, save time and call Western Rooter. Tell them to send Daniel Westereng and he will do a fantastic job!"

"This company was FANTASTIC. Javier completely understood the problem and didn't waste my time or money. Never tried to upsell like one of the past plumbers tried to pull with me. This was my third plumbing company before going through HomeAdvisor for Alliance United. You all saved me $3,500 in unnecessary work!!! Thank you!!!"

"We scheduled an appointment with Johns Plumbing to get an estimate for a couple of non-emmergency issues including water heater replacement and faucet installation. Price was fair and we decided to go with them. Plumbers were working fast, and they completed all the work within one day. I would recommend Johns Plumbing to everyone."

"I recently had a gas leak scare and called L.A. Plumbing pros. He was fantastic! The plumber who came out his name was Victor he was professional, communicative, and very efficient. He was able to quickly locate the source of the gas leak and explained everything clearly throughout the process. I felt confident in his expertise and appreciated his willingness to answer all my questions. The repair itself was done promptly and the work area was left clean afterwards. I highly recommend L.A. Plumbing pros for any plumbing needs, especially if you suspect a gas leak. Their fast response, clear communication, and quality service were all top-notch!"

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:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
Before finding the right plumber for your job, there are a few questions that you should ask, including:
Are you licensed and insured?
Do you charge for estimates?
Is your fee a flat rate, or is it hourly?
Who will do the work? Are they all licensed and qualified plumbers?
What happens if any breaks or damages occur?
What is your response time in an emergency?
Is cleanup included in the quote?
Do your services come with a guarantee?
Discussing these questions with your plumbing contractor will help eliminate future issues and clarify expectations.
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.
Typically, plumbing repairs cost 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.
The average cost to hire a plumber 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. It’s also important to note that these prices can go up on holidays, and emergency plumber rates average $150 per hour, in addition to a flat-rate trip fee of $100 to $350.
From average costs to expert advice, get all the answers you need to get your job done.
