Custom plumbing was the first company to call me back when I needed help. The technician that arrived, Andrew Marquez, was professional, courteous, and easy to speak with. He reassured me that he could get things resolved quickly and at a reasonable price, which is rare these days.

Andrew kept me informed at every stage of the project, made himself available for follow up questions and worked hand in hand with the restoration company to fix my plumbing and subsequent water damage. I have worked with several plumbing companies, but none of them came close to providing this level of client focused service. I will always call Andrew for this home, or any home in the future.

Simple Fix - I was having issues with my pilot light, on my water heater, staying on. Miguel came to the house and helped to assist me with getting the pilot light lit. Miguel was courteous, nice and willing to answer any questions. Their ability to come to my house within a short window was very helpful. I will use them again if ever I need a plumber!!!

Very disappointed – please get a second opinion

I contacted this plumbing company because my water heater was not producing proper hot water, even though the unit is relatively new (installed in 2022 in a new-build home).

The technicians came out and, after only a brief inspection, told me the problem was the shower cartridges and insisted they needed to be replaced. I explained multiple times that the issue was not just the showers — all sinks, including the kitchen sink, were also not getting hot water. My concerns were repeatedly dismissed, and I was told the sinks were “fine.”

I then asked for pricing and was quoted $500 to replace the cartridges. However, when they returned the next day, the price unexpectedly changed to $500 PER shower, which was not what had been communicated before. This felt extremely misleading. Considering the cartridges themselves cost about $80 each, the labor estimate seemed excessive.

What concerned me most was when I asked if they guaranteed the repair would fix the problem. I was told they could not guarantee it and that there would be no refund even if it didn’t work. At that point, I declined the service.

To make matters worse, this same company also sent a second technician earlier who told me my entire water heater needed to be replaced — which turned out to be completely false.

My father (an engineer) replaced the cartridges himself — and, as I suspected, it did not solve the issue.

I then called another plumber for a second opinion. He walked in, looked at the water heater for a few seconds, identified an open valve mixing cold and hot water, closed it, and the problem was immediately fixed. The total charge was $20.

Overall, I felt my concerns were ignored, the diagnoses were inaccurate, and the pricing was inconsistent and excessive. I strongly recommend getting a second opinion before agreeing to any major repairs or replacements.

I recently had an excellent experience with Mark Auld from Custom Plumbing of Arizona, and I can honestly say he is the best plumber I’ve ever worked with.

I called about a water leak near my meter, and Custom Plumbing of Arizona quickly diagnosed it as an underground mainline leak where the PVC pipe connected to the gate valve at the meter. The repair was no small job — the line was buried nearly three feet deep — but Mark worked tirelessly to excavate the area and properly stub up the line with copper, reconnecting the service line to the meter the right way.

What impressed me most was how meticulous and thorough he was. He carefully explained the problem, took photos, and walked me through everything so I fully understood what was happening. Even though he was covered in mud from digging all day, he remained incredibly professional, friendly, and positive.

After a full day of hard work, Mark even returned the next day to check his work and he fixed a small pinhole leak on the meter to make absolutely sure the job was completely finished. That level of follow-through and integrity is rare.

Throughout the process, Mark was always responsive to my calls and texts and kept me updated. His communication, workmanship, and attitude truly set the standard for what service should look like.

Mark Auld represents his company exceptionally well and builds real trust with customers. This is exactly the kind of experience every homeowner hopes for. I highly recommend Custom Plumbing of Arizona — and if you can request Mark, do it!

Very impressed with Custom Plumbing and particularly my plumber, Andrew. He found issues I didn't know existed and immediately called for mitigation to prevent further damage. The toilets he installed are working perfectly. His attention to detail is above reproach and I've asked that he install the final toilet once repairs are complete. Very grateful to have found a plumbing company I can rely on for any future needs.
