    The soil used to be relatively neat (see the untouched area) but they left a mess.
    Gilbert L.

    This review was about a job done a year ago. An galvanized irrigation pipe leak in a backyard started leaking badly one morning so I was in a rush to have it fixed (much more to conserve water than saving cost). I called AQP because I was confused by another similarly named plumber I used and liked very much before. But stupid me, they sent someone out and started quoting around $2500 for maybe a 40-feet copper pipe replacement. Of course I balked at it. They then said that PVC would be sufficient and would only charge $2000, and throw in also replacing a rusting pipe section where this line connects to main and add a valve. And they would send guys to finish it today. At first I thought at at least my money was spent in getting the job finished promptly. But they sent a teenager 2 hours later to help digging a 40-foot trench from 1:30pm and made a mess. Didn't actually finish until 7:30pm when it's turning dark. The owner Kory came and told me that unfortunately they won't replace the extra section due to lack of time. And worst of all, because the PVC glue was still drying they wouldn't even test that it worked before leaving. A big mess was left behind in the yard (see photos). I feel severely short-changed for a bad deal: $2K for a 40-feet dig and PVC pipe replacement, without the extra junction/valve replacement originally promised. I was left with a mess, and I spent ONE HOUR the next day going back and forth between the main valve and the backyard to slowly ramp up the water flow to make sure that the pipe was fine.

    My only toilet was plugged and Kory arrived in a timely manner. (It was on a Sunday). He was professional, respectful and took care of business!! I definitely recommend Advanced Quality Plumbing.

    I need a bid to move a water line only about 6 feet for a washing machine. Plus want to drain to go directly into drain & not drain into the garage sink. I have pictures. House is I. Santa Clara. Can I get an estimate?

    Hi Ann, we can help. Send an email to joel@advancedqualityplumbing.com with the pictures. Thanks!

    I just called and it sure sounds like they’re out of business. Are they or are they not in business?

    We are not out of business. If you want to reach our office please call (408) 300-5072.

    Is this company licensed, bonded and insured with the Contractors State License Board?

    We are licensed with the CSLB and hold a C-36 Plumbing License (#854482). We also are bonded and insured.

    Do you charge a fee to come out for estimates?

    We come out for free estimates.

    I just called and the message said the office is closed indefinitely. What's up?

    Office is open, and we are back in business. There was a brief period in 2017-2018 when we were closed due to a death in the family, and it took a while for our company to rebound from that.

Got good, fair ballpark quote over the phone from Alex, so knew what to expect. Got appmt scheduled for that afternoon with Brian (tech) to come check out our issue. As expected, he diagnosed the issue and was able to install a new water heater that same visit. Got the whole job or replacing the old water heater done within the afternoon!

Alex sent our technician, Rojo, who helped install a new 40-gallon gas water heater in our indoor utility closet, and he was incredibly diligent, professional, and efficient from start to finish. Installing a tank in an inside closet can be tricky, but Rojo handled the entire job seamlessly in just 2 hours. He replaced everything with high-quality components, including: * New hot and cold water flex lines * A brand new water shut-off valve * A new gas flex line and sediment trap * Fully reworked earthquake straps (to meet California safety codes) * Properly updated T&P line and venting He also took care of the removal and disposal of our heavy 18 yr old tank, leaving the utility closet completely clean. If you want fair pricing, expert specialized service, and a technician who respects your time and home, call Water Heater Masters and ask for Rojo. Highly recommended!

    Knockout did an excellent job for us and I highly recommend them. We started our journey with an…read moreestimate to replace all the vertical and horizontal waste water pipes under our home. Our house is 70 years old and we noticed cast iron pipes that seem to be deteriorating. We looked it up and their life rage is about 70 years so we bit the bullet and got estimates from 4 different companies. They all seemed good but Knockout offered some things the others did not. They offered a 25 year transferable warranty, they acquired and arranged for permits. They also put back the dry wall that they had to removed to do the job. The man that did the texturing did a great job. He matched the 70 year old texturing style that was in our family room. I was truly amazed. This sewer pipe replacement, grew to include all the water pipes, and then to replace the sewer line from the house to the street and unknown to use we had a second line that was leaking under our garage floor. This turned into a really really big job. It could have been a nightmare but it was not. Martin, Axil and the rest of the crew totally took care of us and our house. Every day I would receive an email telling me when they would be there to work or when an inspection was happening. They were the most cautious and careful of our house. They protected my floors, and carpet and walls. THEY NEVER LEFT A MESS EVER. I watched them clean, sweep and scrub down our driveway when they had used it as a work space. They were absolutely incredible. Clean, neat, work that was approved by the city and sewer department and great communication with us the entire time. I HIGHLY RECOMMEND THEM IF YOU HAVE ANY PLUMBING NEEDS BUT ESPECIALLY IF YOU HAVE A BIG JOB. THANK KNOCKOUT, YOUR WORK ETHIC KNOCKED ME OUT. Susan and Mark Kontich
