Our 25+ years of very good experience with Gem destroyed by an utterly incompetent dispatcher.We contacted Gem to have our water heater replaced. Provided the dispatcher with photos of our old water heater, model/maker information, and water heater location. We requested an Energy Star model. We were quoted an out of the door price. When the plumbers show up, they brought a water heater with an incorrect dimension which required modification to the water lines. We tacitly agreed to the modification as we tried to accommodate Gem as we, up to this point, have had a very good experience with them for 25+ years. After the modification was made, we discovered the water heater was NOT Energy Star. We halted the work and requested a phone call from the dispatcher to find out why the two mistakes. Long story short, we receive no reply until THREE DAYS LATER. We found another plumber to finish the work.Gem sent us a bill for the modification which was resulted from the dispatchers mistake. $845 for removing old water heater and re-routing water lines.We reached out to Gem. Hoping to have a solution to this as we were basically held responsible for Gems mistakes. No luck.Well, we paid the bill as we see no benefit to escalating this and prefer to move on with our life.However, we will NEVER use Gem again, will not refer Gem to anyone, and would discourage anyone from working with Gem.

I used Gem plumbing when an outdoor hose spigot broke last year. They used plastic parts that were immediately leaking and eventually broke, even though we barely use that spigot. We had to turn our main water off when the plastic pieces broke to stop the flood. They told me it would be two days to come repair it again because they only have two vans working and they would be charging me full price again also. Two days, even though I told them we cant flush our toilets. They seemed not to care at all. We called a different plumber. It was a plastic piece that broke in half attached directly to the spigot with no support Terrible.

Always a favorite for more than 65 yrs!

Very friendly, responsive and highly capable. Fast service, quality work at very reasonable prices. Highly recommended.

Gem Plumbing is awesome! I am glad I found them over 10 years ago. I can count on them for all my plumbing and air conditioning needs at a moments notice. Its important to be able to find a well experienced plumber and one that you can trust! Everyone is so helpful and friendly. Thank you.

They are superb in every way--we have used them for 20 years and happily so.

Gary and Jorge began by arriving on time. Gary reviewed the situation, a water leak in a pipe under a foundation wall and patio slab. This meant that the leak itself was under the foundation wall and patio slab. The pipes origin was under the house (not a slab, but a raised foundation). I suggested that they might want to consider simply cutting the pipe under the house, abandoning it, and installing a new pipe from the same source and extending it through a ventilation vent in the foundation and attaching the new pipe to the part of the old one in the yard. Gary agreed that this was the fastest and most cost effective solution. Two hours later, the job was finished. The cost was appropriate for two men working for two hours, including copper pipe and other copper and bronze fittings. This is our second experience with Gem Plumbing of Sierra Madre, California, both with very successful outcomes.

NO FREE ESTIMATE! One star because I could not give zero star!! The reason for the call was “no hot water from the shower”. The plumber came and turned on the water for both showers and one sink. After less than 10 minutes, he told me it’s probably the valve inside the shower. So after he changed the valve, the problem should be fixed! We proceeded to set the date for next appointment.I trusted the plumber’s assessment only to find out the next day that.. if we just turn the knob less than half way, the water temp is HOT! I believe the plumber who came was an experienced one with the way he talked to me. Therefore there are only two reasons for a second appointment to chang the valve: 1. He took advantage of my ignorance to charge more money. 2. He is incompetent and could not tell the difference on how different showers work.I was charged close to $120 for 10 minutes of nothing!

We highly recommend Gem Plumbing and have been using their services for years now.

Quick response, good service, good prices, friendly staff and technicians. I will use them again, you should use them too.

They are super professional and charge you a fair price.

They are the best at what they do --- when we have HVAC or plumbing issues, GEM is who we call. Honest. Reputable. Helpful.

Honest and very professional I would definitely recommend this company to my family and friends who need any plumbing!!

A very good company
