Sidney and Diego and Raul jr did a great job Of re-plumbing our sewer lines. It wasn't an Easy task, as it took them over a week and a half to complete. They did it with minimal impact on my schedule or the schedule of my kids. Everything was perfect afterwards and all waste was hauled away. With two teenagers in the house this will be a nice addition and a piece of mind. read more

I received several noticed from my water company saying that we have a leak, causing several gallons of water to be lost every hour. After performing several checks around our townhouse, we just could not find the leak. Alert plumbing was able to identify a leak coming from a pipe connected to the main line. They were able to start the repair the same day. Before we called the project done, the plumber wanted to monitor the area for 2 more days to make sure there weren't any other leaks further down the pipe. Because of my work, I tend to contact many different plumbers for various fixes around my office. Alert Plumbing is by far the easiest plumber I've worked with! Communication was great, they were on time, and their work is thorough. The price was a lot more affordable than I initially thought it would be too! I highly recommend Alert Plumbing! read more

Alert plumbing is my go to. I called them because I was having a leak under my sink and we needed some other things checked. I spoke with Sharice on the phone to book the appointment and she is always nice and professional. Reuben came over and was professional as always. He assisted us with the issue and quoted us on the other thing. The quote was fair. The one thing I liked is he gave options to save some money. Thank you Alert Plumbing. read more

Alert plumbing did our house repipe a couple years ago and also just compelled a job where we had to replace our shower. Ruben is very friendly and cares about his clients. Thank you Chris for your detailed work and taking good care of us. Chis communicated with us every step of the way and I felt very confident in his work. read more

I asked Alert Plumbing to replace my galvanized water pipes from the water main to the garage door with copper pipes in 2022, and they sent a really great guy Joey to install it. Just a couple of days ago I had a leak issue and they sent Chris and Diego to fix it and didn't charge me anything. Thanks guys! read more

Amazing response and service. My sink backed up around 7:00pm and I called Alert. They had someone come out the same evening within an hour and fixed my problem. The technician, Chris, was awesome. Super nice and very neat by cleaning up after completing his work. Highly recommended! read more

Ruben and Diego very polite and professional. We had a toilet leak and they came out and took care of it!

Quick turn around!! Sidney quickly identified the issue and fixed it with no additional charges. Great price

I've contacted Alert Plumbing for plumbing issues which turned out to be a larger project than anticipated but they got the job done within a week. The recent call I did was for a simpler issue, replacing a shower faucet valve and cartridge. Joey was in and out, explained the work, the length of time the water would be shut off and he was done in less than an hour. It's been a few days and the faucet hasn't leaked. Price is slightly high but I got my issue worked on within the time frame I was quoted. Customer service told me she will have someone stop by between 10-12 pm, Joey arrived by 11 am and was done before noon. read more

Chris and Sidney replaced my water heater and the job was not easy! My water heater is in a closet 5 feet in the air very tight space made it happen, very personable, quck, and had the best rate out of everyone! From the interaction of first calling into the office to Chris coming out service was great and would highly recommend. Service was provided in Fremont. read more

Joey D. did a fantastic job fixing the two toilets in our house. Service was prompt and repair was done according to the promised timeframe. I would definitely recommend this to my family and friends! read more

I recently had an issue with the mainline backing up. I contacted Alert Plumbing and a couple of hours later Sidney arrived and diagnosed the problem. He finished the work in a timely manner and even made sure the work area was clean before he left. I will definitely call Alert Plumbing again in the future if I have any plumbing issues. read more

These guys focus on customer service and doing a great job- which is the TWO key things you want from a plumber. I hired them to take a look at my 100-year-old house plumbing, to investigate a damp patch in the basement crawlspace. Joey and his crew IMMEDIATELY identify a hairline crack in my plumbing, help me figure out which one it was, and got me videos of the leak in action. Then they gave me their expert recommendation (you should replace the cast iron pipes, and put in a cleanout") and then worked to make that happen, despite the multiple challenges that popped up in the cramped space. What I liked is that when they have minor mishaps (one of the crew accidentally broke a windowpane next to the pipes) Joey immediately calls me and asks what I'd like to do with it, and offered to repair it themselves- and they had a window guy come in that same day and fixed it, no extra charge. They did not hide it, or put a board up over it, or even just maybe don't mention it- I probably wouldn't have noticed til later. Instead they were professional the entire way through, and made the process as hands-off as I wanted, and also explained and documented as much as I wanted as well. It's hard to find a good professional in areas you don't personally know well, so a good artisan tradesman is really valuable. I'm hiring them again to replace other clay piping and extend plumbing to the back house- it's a no brainer. read more

Jose was great with a stubborn kitchen sink clog. He was patient and cleaned up everything afterwards. Really awesome service.

Joey was great. First visit looked at the problem. Described work necessary gave a price for the repair. Next visit came prepared and got the job done. Nice guy. Got the job done. Thumbs up!! read more

Great company all the way around, from the admin team to the field technicians, Sid was the foreman on site he got my house completely re-piped and completed within one week. I couldn't be happier with the cleanliness and the attention to detail. I was kept informed throughout the entire process. I will recommend Alert plumbing to anyone & my clients! read more

Alert Plumbing did an amazing job in a short amount of time after we experienced emergency pipe burst that caused major damage to an upstairs bathroom.

Who knew they do more than just plumbing - serious one-stop shop that helped us seamlessly through the entire process! read more

I had pipes under my home replaced by Ruben and his team at alert plumbing. They were straight forward, had competitive prices, and went through all the details on what the problem was. They were recommended by a family who had a new drain pipe installed and also recommended by a friend. Recently a family friend had a high water bill and I called Ruben. The family friend called their own plumber. The other plumber from Yelp that didn't find any issues, but could not explain why the water bill was almost 4x times the regular bill. Ruben came by early and was able to explain why the toilet flush valve was the problem and some common sense to understand how to see and test for ourselves. He was prompt, honest, and gave a cost vs value in terms of replacing parts on an old toilet vs installing a quality toilet that will last years. Overall I feel pretty confident having worked with him and others in our friends and family group that they are fair and professional. They show up and act professionally much better than plumbers we had worked with in the past. read more

While cleaning morning of Christmas Eve to prepare our house for a family gathering later, our main toilet ended up getting clogged. Luckily we had a 2nd bathroom & most importantly had Chris come out to fix it for us! We were so thankful it was done within the same day since we had very low expectations to begin with but we were so pleased with their service. Would highly recommend to anyone needing help! read more

What can I say about Alert Plumbing? Ruben, Raul, Jose and Sidney have been incredible. Little did we know the unfortunate journey we would be on. After a rat gnawed through a water softener hose would we discover how bad things actually were under our house. After replacing the hose, there were several wet spots under our house that followed along the sewer line. After a repair by Sidney and a follow up check by Ruben, we learned our 70 year old cast iron sewer system was leaking in several places and the drains were clogged beyond recognition. They were plugged yet the drains somehow were flowing. Raul and Jose have been the primary workers throughout the week removing the old cast iron pipes under the house while upgrading and updating our drains and sewer line. They have been punctual, professional and extremely respectful of our home. Drop cloths and tarps are meticulously arranged daily and areas tarped over to not disturb clothes and other items. Every day we get an update on what they are doing and what they plan to accomplish. We are close to being done only to learn the exterior clean out was only upgraded from the street to about 10 feet from the house. The clay pipe is cracked and misaligned with the update done about 25 years ago. Why would another plumber stop 10 feet short of completing the job? Ruben and his crew showed us the video and explained they need to dig down four feet to remove and replace this 10 foot section. Just more problems for us but so happy we have this team helping us through yet another major plumbing issue. They have been truthful, honest and look you in the eye when explaining everything. The pricing has been fair, but the professionalism is what truly stands out. I firmly believe Ruben, Raul, Jose and Sidney are great plumbers but also incredible people. They are masters of their craft and we are grateful for them identifying, explaining, and performing this difficult job with a smile on their faces. read more

Recently moved to the area, we quickly encountered a couple minor plumbing issues in our home. After doing some research, we came across Alert Plumbing and we're so glad we did! After scheduling, Raul came the same day and inspected the issue with our washing machine promptly. He quickly found the problem and fixed right away. Very knowledgeable and personable, Raul made me feel so much better about my situation and afterwards once everything was fixed. I've since called Alert Plumbing and Raul for other issues in my home, both small and large. I won't contact another plumber anywhere else! Alert Plumbing has been great. read more

I like to believe I have some experience as a handyman, installing faucets and toilet flaps, interpreting IKEA assembly instructions, etc. But I found myself in a pickle when plunging a sink to improve its drain resulted in the opposite of what I had intended. Setting my pride aside, I put on my best puppy dog eyes and admitted to my wife that I'd need to hire help. Alert Plumbing promptly responded to my request, helped me schedule the repair (yesterday) and helped fix my sink. Joey snaked my sink to get it draining again and was also very kind in explaining what he'd do, cost, etc. Without hesitation, I would ask for their services again! Hoping that won't be the case anytime soon though, haha. read more

I contacted Alert Plumbing for an issue with my upstairs tub. In addition, I requested an estimate on the cost for a re-pipe (downstairs) that was recommended by another plumber. Not only did Ruben get my tub draining again, he crawled under my home to fully assess the condition of my pipes. He reported back that they were in fine condition and did not need to be replaced. The prior plumber never went under the house; he made his assessment simply by looking at the pipe under my kitchen sink which was clogged at the time. If you want an honest, qualified plumbing company, Alert Plumbing is for you. read more

In November 2013, our sewer line needed replacing and a technician came out to perform the job. Today in 2024, we had a camera in there and saw that some joints were not done properly by the previous technician, but Ruben and his wife (the owners) really care about its business reputations, came out to perform the service agreement after 10 years. Alert Plumbing, you guys are Excellent! read more

Contacted the business in the late afternoon, a very kind woman answered, took my information and said she'd check to see if anyone of her techs were available. She called back as promised within the hour and said that Brian would be out within the hour as well. Brian was diligent, kind and knowledgeable. His equipment failed him, and said he'd be back the next morning. (Understandable). He showed up the next morning, cleared the clogged drain, showed me the roots that were at the end of the snake. And explained (which I already knew) of a house this old, that we're going to need a drain / sewer replaced sooner than later. (I don't think I'm ever going to retire ) Nonetheless, service was excellent!! Definitely will contact Alert Plumbing again. read more

Yesterday Sidney from Alert Plumbing came initially to repair a toilet leak; however after he took apart the toilet, we saw that the porcelain was broken and thus we needed a new toilet. Sidney called his boss and we were given a couple choices as to quality of a new toilet. He left got the new toilet returned and installed it. It looked so good we ended up having Sidney put one in the second bathroom as well. We've used Alert Plumbing several times and they've always been reliable and fair. We highly recommend them. read more

Job Done: Replacing all old (old, old, old) galvanized pipes with copper in two bathrooms (showers/toilets/sinks), kitchen (sink, dishwasher, refridge water), washing machine, water heater & outside faucets. We were referred to Alert Plumbing by a good friend. Ruben was very responsive to our initial call. He gave us a thorough evaluation of what he thought needed to be done, quoted a reasonable price and didn't try to upsell. Brian and all the workers were very friendly, and disruption of our home routine was kept to a minimum. They were VERY detail-oriented, from tear out, installation, clean up, and finishing touches. They even threw in some nice extras. We would hire them again in a heartbeat. read more
