Recommended Customer Reviews

I can see why they have great reviews. Professional, diligent, knowledgeable with excellent service. They cover all of San Diego county, not just north county. I call vendors for estimates on real estate properties, they offer great reasonable rates.

So pleased with the service Magnum Plumbing has provided for us! Aven was professional, easy to schedule an appointment with, and was very knowledgeable about the issue we were having with our hot water heater amongst other things! I've had to deal with many plumbing companies in the past few years since living in this home, and Magnum has by far exceeded my expectations! Thank you Aven!

My brother was installing a new bathroom sink..my almost 40 year old valves crumbled while he was trying to get them off. Aven called me back immediately after I requested a quote and came out the next day he phoned 10 mins before he arrive to let me know he was on the way. As it turned out it was a bigger job than he had anticipated over the phone but set me up with an appointment the next day and fixed it so I could use the water until he got there.
Troy came on time fixed everything with in a little over an hour fast professional and fair price.
i would recommend these guys for all of your plumbing needs, hopefully i don't have any in the near future but I will defiantly call Magnum If I do!!!

Magnum Plumbing is top notch! They did our kitchen remodel and communicated the steps along the way. Aven and his team not only did great work, they were also very clean and professional. We highly recommend!! Thanks Magnum!

We used Magnum Plumbing for a project and We couldn't be happier with our experience. Aven was SO professional at all times, reliable, and educated. He explained the process and answered every question we had. I highly recommend using them. Magnum does not disappoint! Thank you, Aven and the Magnum team for making this experience so easy and stress free!

Aven was friendly when we spoke with him. He assured us his company was the right choice and he could take care of our plumbing issue. We scheduled an appointment and shortly before the scheduled appointment time, he texted that his company had to cancel the appointment. We texted back twice asking him for a reschedule date. He never responded to our texts and did not even have the courtesy to contact us again to let us know he would not be able to reschedule or ever take care of our plumbing needs. We suggest continuing your search for a good, reliable plumber as Magnum is not only unreliable, but inconsiderate in their dealings with potential customers, and the owners are clearly flakes!

Magnum plumbing was always on time to the appointments. Aven was extremely helpful in assessing the job, recommending courses of action, and executing the plan quickly and efficiently. I would recommend to anyone and absolutely would call again for future plumbing needs. You would be crazy not to call Aven for your next plumbing project!

Aven and Hector were polite, professional and efficient. Aven responded quickly to an urgent request and the problem was fixed later that day. I'll definitely go with them again for future projects.

Aven and his team are top notch. He takes great pride in his work and it shows. We opened a new grooming shop and needed a tub installed on short notice and he was quick to respond and get it done. We would recommend them highly to anyone who needs an honest plumber who does great work!

We replaced our 12 year old water heater and called Magnum to do the job.
I highly recommend this company. Family owned and they really go the extra mile.
I will definitely recommend them to anyone with plumbing needs.
