Pipe bursting is a techinque of replacing existing sewer pipes. The existing pipe, once busted, becomes the guide path for the new pipe being installed. This techinique burst the old pipe and displaces the fragmented old pipe into the surrounding soil, which creates a hole roughly the same dimension as the original.

These people are HONEST and fair! My brother recommended them as they have worked with him at his restaurants for many years. My drain needed to be cleaned out with a hydro jet. Plumbing Master sent Julio, who was WONDERFUL. He did a thorough job and answered all of my questions, including tips on how to maintain my drains. I was so happy with the service that I asked Julio to please install my new kitchen faucet.

All this was done at a FRACTION of the price of what a very dishonest chain tried to charge me. If you want EXCELLENT QUALITY service and FAIR prices, Plumbing Master should be your first and only call.

As a maintenance coordinator trapped in an office cubicle 400 miles away, I breathe a sigh of relief when I have an issue in Plumbing Master's service area. I know I can send them a Work Order and not have to follow up or nag, I just know if will be completed in a professional and affordable manner.

One of the drivers here followed me through a shopping center parking lot in as he whistled at me making sexual remarks. This is not okay whatsoever! Who are you guys hiring considering there's another negative review regarding employee misconduct?!

I called them for a service call. And explained to the lady that answered my situation. And asked me if this was a business or a residential? I said residential and they told No we don't do residential!

I recently moved to Riverside and this was my fourth time calling a different plumber. I was very impressed with Plumbing Master. David came out and was very professional and knowledgeable. My toilet had no wax ring which was producing the sewer smell in my bathroom and he was able to quickly diagnose the problem. Will definitely use them again.

I have used other plumbing companies in the past that charged an arm and a leg to unclog one backed up drain. I was the most satisfied with the customer service Plumbing Masters provided and with the work they did at my home. The plumber that came out was very kind and professional. He was able to unclog several backed up drains and pointed out to me exactly what caused my drains to get clogged up. I would recommend Plumbing Masters to anyone who is looking for great customers service, a good response time, and reasonable pricing.

The Plumbing Master team was great. I placed a service call regarding a hot water issue. I had one technician arrive to trouble shoot, my existing unit was old. I gave them approval to replace. Technician removed old heater and cleaned area for installation. Second technician arrived and they installed quickly and correctly. Robert A and Danny W were very professional, knowledge and friendly. I have had no other issues with my hot water. Thank you Plumbing Master. Deborah C

If you need a plumber and want a quality job done the first time then try them. I use them in my restaurant in Monrovia and they are out to help me same day. The staff is always polite and they do not over charge compared to some other companies
