Recommended Customer Reviews

Magnum Plumbing was so awesome! He came right out and fixed my problems. Aven will be our plumber for now on! Thank you Tons from Illusions Hair Studio!!

These guys were awesome. Aven Was very professional and responded extremely quickly. We had a faulty faucet which he replaced and did so on very short notice. Pricing was very competitive and I would definitely go back to these guys no matter what. 6 stars

Very pleased with Aven's work. He was responsive and professional. We had a clogged shower that was due to corroded pipes underneath. I got several quotes since this was a big job and Aven won with a fair price and good communication / professionalism. I will call him again for help with my San Diego rental units.

Aven is awesome. Called him on a Friday afternoon at 4:45 answered my call and was at the house Saturday morning to take care of my emergency.
Great guy extremely knowledgable and very reasonable on price.
Highly recommend.

I reached out to Magnum Plumbing to get some help with a broken sink valve. Aven reached back out to me quickly with a very reasonable estimate, and was available to come to the house early the next day to get started. When he showed up, he was on time, friendly and very professional. He did a thorough and quick job of fixing the broken sink valve, stuck to his initial estimate price, and was happy to let me pick his brain on some unrelated plumbing issues we have been having. I will be sure to reach back out to Magnum Plumbing with any future plumbing projects!

so i want to to thank you for being so professional because we need plumbers like you in san diego.
i will have them do all of my projects thanks for good work guys.

This plumbing company was hired to ""clean up"" some issues that our contractor's guys couldn't figure out. Aven showed up right on time, was thorough, personable and took care of all of our outstanding plumbing concerns. I would highly recommend them!

What a great company, customer service A+. I called for a repair on a high end toilet and explained that Dad was handicapped and needed a repair ASAP. When they got here they were knowledgeable with the Toto system. I will be using their service from now on. I highly recommend this company, also very professional.

Aven, was a great help! The water heater was leaking the day before 4th July. He came right out and took care of everything quickly and efficiently. He is even coming back to do some more work for me. I would highly recommend him. Very fair pricing.

Professional, punctual and fair are just few words that describe Magnum Plumbing. I use them for all my plumbing needs. After going through plumber after plumber it was a breath of fresh air to have these guys show up and handle business. Thanks for everything Magnum Plumbing!
