Gem saved us from a heat wave! It was 102 degrees and our A/C wasn't working. I called Gem at 6:30 PM hoping to get an appointment for the following day. The guy happened to be in the area and came right over! He was here in like 5 minutes! He knew exactly what was wrong, had the replacement part in his truck, and we had A/C within half an hour. This is the best service I've ever had from a repair company!

Experts in difficult jobs. They had to fix the sewage pipes of my 1911 home. The pipes were corroding and crumbling. Some things were done poorly by past plumbers and they brought everything up to code. In addition, they had to work amid a contentious relationship between my soon to be ex-spouse and myself to coordinate the repairs, which was, to understate, extremely difficult. But they listened carefully, were empathetic, and responded courteously and professionally throughout. Chris and Esteban are intelligent, friendly, respectful, trustworthy, expert technicians. They are respectful to women and are not condescending or patronizing in any way. I could leave them alone in my house or observe their work; both with ease. If there wer fixes that have been miscommunicated (which often can happen with large involved jobs), they don't stop until their customers are happily satisfied. With the replacement if our kitchen faucet, Dave went out of his way to make sure I was completely satisfied. The parts came in very quickly. They also respond to customers quickly by phone and showed up on time to scheduled appointments. Their prices are fair and reasonable. Highly recommend for little to big jobs. Definitely worth keeping their number on your speed dial!

The plumber was rude and had an absolutely terrible attitude; stay away from this company.

We had someone named Josh from this terrible company come to our place last month to take a look at our heater/AC unit because we requested a quote.
After going up on the roof he came downstairs and spoke to my wife and I. He gave us an estimate on what it would cost to fix the unit (he said it would be around $450) and said that he'd call the next morning to give us an official repair quote as well as a quote for how much it would be to replace the unit.
He did not call me the next day. Instead, we found an old business card jammed into the front door in the evening stating that ""heater is fixed. Bill will be in the mail. Thank you. Merry Christmas!"" Not only did he not call us nor ask us what we wanted to do, he did the repair work (allegedly-we do not know for sure) and scribbled a hand-written note on an old business card saying that we would get stuck paying a bill!!!
This person Josh then called us after we complained and stated that both my wife and I had authorized him to do the work, which he had not. We did not authorize any payment whatsoever.
We refuse to pay this bill and have sent them emails but no one has yet to respond.
Never do business with this company, they are an untrustworthy business and should be ashamed of how they represent themselves in the community.

I've been a customer for many years, however, over the past years, I think they've gotten complacent about their work. They've been to the house a few times recently to fix things,but it's never fixed for good and I paid a lot of money. Unfortunately I may need to look for a new plumber which saddens me as they used to be so good. Not sure who's ""watching the store"" anymore as quality has decreased.

I have used Gem many times in the past. They have always been prompt but expensive. Most recently I used them to clear an area drain clogged with roots. I think a sub contractor may have been used but can't say for sure. After the drain was cleared I asked for a price to scope the drain with a camera. What I heard was $50.00 which sounded more than reasonable. I gave the go-ahead.
The work was successfully completed. The drain was cleared and the camera inspection revealed 40' of cracked line. I asked for a bill and and an estimate to repair the drain.. The plumber said a bill would be sent. I didn't get the full price which was a rookie mistake on my part.
The bill arrives and the cost of the inspection, to my surprise, was 200.00! A 150.00 discrepancy. When I called to question the bill I was told the minimum charge for a camera inspection was 275.00 and that I had gotten a break on the cost. No explanation was given for the discount.
It's possible that I didn't hear the price correctly so I'll write this off as my mistake but won't be using them again.

They were suppose to be here between 1 and 5 p.m. When I called at 4:45 p.m. to see if they were coming, a very rude woman told me I would have to wait until 5:00 before they would even do anything. After that rude response, I never bothered calling.
And they never bothered showing up. You wonder how this company stays in business.

These guys are great!! Called about a main drain problem at noon. 2:30 everything done. That is what I call service.

Dave Pedroza and his entire team at GEM Plumbing are wonderful professionals. We had many projects recently from a main line sewer needing replacement to a furnace needing upgrades to installing fixtures.
GEM Plumbing got to work quickly, did exceptional work, and all at reasonable prices.
We highly recommend GEM Plumbing for all plumbing and heating/air conditioning jobs big and small.

I'll use these guys again. GEM has provided me with both plumbing and HVAC services, which I've been very pleased with. W/re HVAC, among other things, they sealed the leaks in my flex duct work (caused by other tradesmen while under the house) and balanced the flow with new and existing dampers. The plumbers have helped with issues ranging from water heater to irrigation repair and gas line extension. They work hard, clean up thoroughly and communicate well.
