Use these tips to help ensure your plumber is reliable and trustworthy before you hire them:

• Read their reviews: You can get a sense of their trustworthiness in the customer reviews. For example, keep an eye out for reviews that mention if the plumber showed up on time and charged a fair price. 

• Ask for references: Sometimes, reviews aren't always the best option for vetting plumbers. Consider asking them for references as well to learn about their experience. 

• Verify their license and insurance: Contact your state licensing board or visit its website to verify that the plumber's state license (which is usually either a master plumbing, journey-level plumbing or a contractor's license) and their insurance is in good standing. 

• Carefully review the quotes: Make sure you understand how much the plumber is charging for labor and materials. If these costs seem inflated — or if the initial estimate over the phone is suspiciously lower than the on-site estimate — ask the plumber to explain. When in doubt, looking elsewhere.

• Find out if they offer warranties: A plumber who offers a warranty or guarantee will (in most cases) cover the cost of repairs and material defects if the job wasn't done correctly. So if you experience leaks, loose joints or other issues soon after they completed the project, your warranty may cover the cost of repairs.

Nationwide, plumbers charge an hourly rate that ranges from about $80 to $150*, according to Thumbtack data. There are many factors that can impact how much it costs to hire a plumber. For example:

• The cost of materials. Does the plumber need provide new piping material or do they just need to bring their basic tools?).

• The cost of labor. How many workers are needed for the project? How long will the project take?

• The scope of the project. Does the plumber need to patch up a hole in the pipe or do they need to replace an entire section of pipe?

Contact a few plumbers and give them details for your project so you can receive a more accurate estimate.

A common sign that a plumber may be overcharging you is if they provide a final estimate without looking at or diagnosing your problem. In most cases, a plumber should come to your home to inspect the plumbing issue and understand the scope of the project before creating a final estimate. 

Also, if a plumber gives you an unrealistically low bid upfront before adding unexpected charges later on, this might be a sign of overcharging. If they bring in too many workers or add excessive labor hours for an obviously simple job, that’s a potential red flag. In these cases, you might want to get a second (and third) opinion from other local plumbers.

To avoid being overcharged, make sure you’re doing your due diligence when researching local plumbers. Read customer reviews, ask for several quotes and make sure they’re licensed and insured.

Some plumbers might charge extra on weekends and holidays. Contact them or check their profiles or websites to find out. It might be a good idea to make a list of plumbers who don’t charge higher rates on those days in case you need emergency services in the future.

Most simple, residential plumbing jobs and repairs can be completed within a few hours. This would include things like installing a new sink, clearing a clog in a pipe or toilet or installing a dishwasher. 

However, some plumbing jobs can take much longer. For instance, you can expect a longer timeline if demolition is needed to reach a pipe, digging is required to get to a gas line or if your plumber needs to order special parts or materials. 

Remember: The timeline for your project will vary depending on many factors. Always ask your pro to provide an estimate.

If your DIY plumbing project isn’t going according to plan, it may be time to bring in a professional. Consider hiring a plumber if you encounter:

• More extensive pipe damage than expected

• Leaks or damage in hard-to-reach places

• Tasks requiring specialized tools or equipment

• Jobs that involve cutting or replacing sections of pipe or fittings

• Work involving hot water, steam or gas

There's nothing wrong with admitting you need a little extra help. If your project is more complicated than you thought, consider hiring a professional.
