Recommended Customer Reviews

Our plumber for many years. Nobody we trust more. Excellent, professional service from the whole team. Fair pricing, knowledgable staff, easy to work with and highly responsive in urgent situations.

Extremely poor service. Not professional at all!
I would not recommend. Moffett plumbing instead or almost anyone else.

After about a dozen attempts at trying to hear back from John (owner of the optimum plumbing) on getting a labor quote, I've decided to write this review.
I first reached out to John in around August of 2021 to get an quote for a water heater/ water softener/ expansion tank/ pressure regulator and some other small odds and ends. Initially, the experience was great. We agreed upon a time to meet and John provided me with a quote in a couple of days.
I was doing my own due diligence and gathering a few quotes from other reputable plumbers in addition to looking at about 30+ contractors for other repairs that the house needed (roof, termite, flooring, kitchen, bathrooms, landscaping, deck etc...). I put the job on hold as I had to prioritize other services first.
It was in mid Oct that I contacted John again about changing my initial quote to labor only for the heater and softener. I would purchase those two units through my business so I could write it off. That's when the issues started occurring. Initially, John told me he was going to be out of town and coming back next week and that he would send me something by Monday. I followed up with him on Thursday and he apologized and said he would send me a quote.
Then, it was radio silence for a few more days. I followed up by sending another text on 11/9 and email on 11/10. Didn't hear anything call. I called him in the following days and got him on the line and he said that he would send me a another an updated quote. Crickets. I finally left him another VM on 11/22 asking for the quote and saying that if I don't hear back from him, I'll just assume he's too busy for this job. It is now 12/1 and I still haven't heard anything back.
It really is discouraging and frankly unprofessional in light of the dozen attempts or so that I've tried reaching out to John only to receive 0 communication back. I'm sure he's an excellent plumber, but, unfortunately I'll never be able to work with him on any projects.

Optimum to the rescue once again! My water heater quit working and Amanda arranged to get someone out the next morning. Todd arrived on time, replaced faulty parts and had it working in less than an hour. No cold shower for me!
John has put together a great team. Friendly, helpful, timely, knowledgeable and professional.
Thank you once again! Until next time...

WOW! If I could make it 10 stars, I would! Optimum's service is stellar from start to finish. I needed to camera a sewer lateral for a city requirement and they were able to send someone out the same day. Todd was well equipped, extremely professional and super efficient. He provided us with a USB key of the camera footage before he left and sent a report for the city the next morning.
When I requested additional information, John and Amanda were very responsive and pleasant.
I highly recommend their services and will be happy to use them for future plumbing needs! Thank you VERY much!

I really like John and find him professional and knowledgeable. Just wished he had followed up w me.

Great service . Showed up when he said he's going to be here. John gave me a estimate and taught me a lot about what was going to happen with my remodel ( tankless , full bathroom , and kitchen,. This was a big job in my mind but John and his crew knew Exactly what needs to be done and did it.. Thank you John for taking care of my project.

Excellent service. Professional business run with long term service in mind. Highly recommend. Intelligent timely responses for large and small problems.

I notice that many others gave Optimum Plumbing a 5-star rating! They are about as creditable a company as you can expect. We have used Optimum many times on commercial jobs and we have been nothing but completely satisfied! It is nice to have a vendor that you can trust and in which you can have complete confidence. They handle a job as though they care and I sincerely appreciate that!

We love referring Optimum Plumbing to our Newport Beach Clients. Great owner operated business with wonderful attention to detail and first class service.
