Recommended Customer Reviews

Sierra Pacific Plumbing is a great, honest, skilled, polite, family owned and fair priced company that I will definitely call first and recommend them to others.
Greg from Sierra Pacific Plumbing came out right away to give us a second opinion / estimate for our tankless water heater that was giving us an error code and not working correctly. Greg was actually recommended from the water heater manufacturing company (Takagi) and I could tell right away, that compared to other plumbers we have had, that he knew what he was doing.
Unlike the other plumbers that gave us estimates and wanted to completely change out our whole tankless water heater, Greg quickly discovered the problem was simply with really high gas pressure coming into the house. He recommended that we call the gas company who came out and fixed the gas pressure fro free. Now our water heater works perfectly! There is nothing wrong with it!
Greg saved us from being scammed by another company who wanted to change out our whole water heater system for almost $3,000!
Thank you Greg!
Greg even suggested some things we could do ourselves to save money. I appreciate that he cares more about being honest than lying to get the job and making a quick buck.
I can relate to the other customers who give this company 5 stars!!!!

Found Sierra Pacific Plumbing through the Beautiful Altadena FB group. We had been using Pasadena Plumbing and had been happy with them, but health issues are plaguing them so we tried SP Plumbing after reading great reviews. I don't know the name of the guy (husband dealt with him), but he was prompt, wrote out a detailed invoice, got everything completed in a timely fashion, and was reasonably priced. So thankful that they did a great job with short notice--came out a few hours after we called. Needed new sink installed and sink stoppers fixed.

I can't say enough good things about this company. They showed up first thing in the morning, in masks, to install a clean out drain at our home, and worked until it was done. They were very professional, honest, and cleaned up after themselves. Josh even brought in my trash cans! They had to dig in our succulent garden to do the work, so when I looked outside, not only had they made sure the holes were filled and the plants were where they belonged, I found Greg watering my garden! Talk about going the extra mile to give outstanding customer service! Greg, Josh, and John, I can't thank you enough.

Referred to Sierra Pacific by a friend. Greg and the rest of his team are very professional and very knowledgeable. They diagnosed the problem quickly and accurately. Scheduled and performed as promised at a very fair cost. Highly recommend Sierra Pacific for plumbing repairs!

I have worked with several plumbers over the years, and Sierra Pacific Plumbing way out shined all the others! I have suffered through numerous professional attempts to solve my sink drain problem, but snaking results just led to partial improvements that gradually worsened until I had to call for help again, trying a different plumber each time. This went on for 10 years! Greg and his extremely professional and competent staff identified the sources of the problem and their results were life changing for me. The daily chore of doing dishes after cooking for my family is soooooo much easier, and almost enjoyable! :) At least I don't have to worry about the dirty water backing up in the adjacent sink every time I run the disposer, forcing me to always remove all the dishes I had washed and set aside to drip dry. Also, my sink drains so fast and efficiently! I kind of hesitated to write this review, because I kind of wanted to keep them to myself! :) You will not be disappointed! Sierra Pacific Plumbing is AMAZING! Carissa

Greg is a plumbing wizard and you probably shouldn't call anyone else.
If you have a Takagi tankless water heater, you DEFINITELY shouldn't call anyone else.

Easy to recommend. Reasonable price, explained the problem and solution clearly, right on time for the appointment ( I had to drive in from out of town to meet him), and very quick repair of a broken pipe in the wall under the kitchen sink. They were referred to me by a trusted hydrojet drain specialist. It is great to have a local trusted plumber.

Works slow, but good work. Prices for material is much to much, 3 to ten times more than plumbing supply stores. Overstated time on the the job as well. It was a little under twice what another quote I had received. I trusted the owner to be fair... wrong! I'm reasonable and would not have a complaint had their price been a little higher than the quote I had. This was ridiculous though! Owner would not negotiate at all. Don't believe the owner when he says he can't give a quote and that he will treat you fairly! Get a firm quote don't be fooled like I was.

I was referred to Sierra Pacific Plumbing from a contractor that was helping with my commercial Lash studio in Alhambra. I was having challenges passing the fire inspection and was in need of a licensed plumber for a water heater that needed permits from an existing job.
I called and spoke to Judy. She was patient and listened to my situation. She was very kind in offering a couple solutions. I hung up the phone knowing things were going to be alright with Judy's reassurance.
I had an appointment with Greg but couldn't show up due to an emergency surgery. He waited at the city hall and was not upset at all. After I recovered I scheduled another appointment with Greg. He met me at the Alhambra City Hall and bc he was there with his plumbing knowledge the city was able to move forward with getting the lash studio up and running.
Turns out I didn't need a licensed plumber! Judy and Greg were there to help anyway they can without any financial gain what so ever. You can tell Judy and Greg are good honest people that love helping people and providing excellent customer service.
Thank you Judy, Greg and the team at Sierra Pacific Plumbing for helping reLASH get our doors open!

We have unfortunately had to use a plumber 3 times now- the first 2 times, Sierra Pacific Plumbing really got us out of a bind. The first time our tankless water heater stopped working and on a friend's referral we used their plumber who came out removed the heater and then quoted us a crazy price- rather than ask if he could remove the heater- he then proceeded to say he wouldn't put the heater back up without payment...my husband found sierra on yelp- we called, Judy called back right away, gave me her personal cell number so we could facetime to get this fixed as soon as possible- they worked with us, called the heater company and we found out we were still under warranty so a new heater was replaced and we only paid for labor. Second time we have roots growing in our pipes and called Sierra to do a hydrojet- they don't do it so we called another plumber who didn't bother to get a camera in like we requested to see if a hydrojet was necessary- just came in and hydrojetted- when the worker put a camera in AFTER- he said we had a ""belly"" and the problem would cost thousands, we requested actual recorded footage, he said manager would come back later to give us camera footage on a drive...they left and didn't return to collect a check or get us footage. We called Sierra and they ran a camera through, said there was no ""belly"" and an annual clean up of the roots would be more productive than the $1,000's worth of work...so now we just call Sierra and skip all the other bull- plus Jeff has been so nice- he's actually shown me how to change out my own house water filters so we can upkeep things on a budget- they're super honest and i like that they are a family owned company.
