At the age of ten, I began shaping my work ethic by working weekends in my grandparents' restaurant, cleaning tables and helping customers. I did this until I turned 16; at 12, I was a newspaper delivery boy for a few years. When I was 13 and 14, I spent my summer vacations working at my uncle's welding shop. I began my plumbing career as my father's apprentice and later relocated to Riverside for opportunities in residential plumbing.
I took a year-long plumbing course at Associated Tech College in San Bernardino, focusing on codes, repairs, and system sizing. Following that, I joined Inland Plumbing as an apprentice, and within a year, I earned a foreman position. I managed the installation of gas systems, drainage, venting, and water services, supervising three team members. Those three years provided me with invaluable experience, and I feel that was where my plumbing foundation was established.

Recommended Customer Reviews

Our water broke on our side of meter! Knowing it was Saturday night it was going to be tough finding someone to come out and fix this very bad leak. After several phone calls Sergio arrived and fixed the problem within a couple of hours! He was worth every penny and we did not feel ""ripped off"". Water company just said sorry, we cannot help. Sergio is such a good plumber!!!

We have used NIR plumbing and referred them for many jobs. They are always on time, very professional and get the job done right. The owner Nick knows what he's talking about and doing when it comes to any plumbing need.

This is the first plumbing company that I've used more than twice. For 4 years now we have used them and have been very pleased with their work and customer service. The owner,Nick has been honest, up front, and easy to work with. Sergio is great. Highly recommend.

The BEST service from the customer service department to the actual tech Sergio everything they did should be a template of all businesses practices. Sergio Cortez was the example of a professional,from his smile ready to serve to his work ethics.I felt that he was really concerned about my concern and was ready to tackle it and he did,something I thought was going to take longer took less then a hour so shout out to NIR Plumbing and there team keep up the good work your going places!

It is with great pleasure that I recommend the fine folks here. NIR Plumbing did my initial house piping and plumbing. Nick and his team, including Sergio, Mike and Juan are fantastic. Service is professional and each member takes great pride in doing the best possible work. They truly care and for each successive plumbing need, they are there for you to remedy each and every situation. Since the initial installation, if I encounter any issues (recently sewage line and dishwasher backing up), the team was there for me and always leave me extremely impressed with their knowledge, kindness, expertise and attitude.

Great service! They were able to come out the same day and exact time I was available.

I was watering my new plant in my back yard at 8pm this evening and went to turn off the pipe....and it wouldn't turn off!! my husband and myself tried everything but it still wouldn't turn off... We immediately went to Yelp and looked for a 24 hr plumber near us. The first
one that came up was NIR Plumbing. We called NIR and Nick answered the phone. He said he would send someone over in about an hour... but they came in about 10 minutes!! Mike came and another Tech and they replaced the pipe with a nice new one.. They were fast, professional, very friendly and extremely knowledgeable! I liked them and we have found ourselves a new plumber. :)

NIR is my new go to plumber. I needed a pressure regulator replaced. Nick responded quickly and sent out a tech the same day. He was knowledgeable, efficient and friendly. I needed a hose bib replaced and he did for a minimal additional charge.

Great plumber. Gets the job done. Very happy with service, will remain a long time customer.

Great friendly guy! he came over the weekend to my office to take care of a portable ceiling water heater that was leaking and flooding our floors. NIR came out and handled the situation quickly. Thank you!
