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.

I had a low pressure on both cold and hot lines, called Alert plumbing for estimate and talked to Liza. Liza is polite and straight talker. Scheduled me right away for a free estimate. Talked to ""JOSE"" and gave me an honest and reasonable quote. Jose and ""Sidney"" of Alert Plumbing are quality oriented and polite. Easy to talk to. They got the job done in a timely manner and Quality is great. I highly recommend Alert Plumbing.

Sidney from Alert Plumbing Inc. was at our house 45 minutes after calling Alert to clear the backup in our bathroom sinks. He immediately got the problem fixed and our worries were alleviated. Sidney was totally professional and his response time was unprecedented in my dealings with past contractors . We will be using Alert in the future with any plumbing concerns

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.

We noticed our water bill has been steadily increasing and spent months looking for our water leak problem but had no success. Came across Alert Plumbing and Ruben came and quickly found our problem. The consultation was free of charge and the service was professional and gave us a lot of confidence in them! We will continue with their service to replace the system that is causing the water leak.

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!

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.

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.
