Amazing service! David and Cole replaced my old faulty water heater on the same day I called. Service was fast and thorough. Both David and Cole were friendly and helpful in making everything work, so I could get my hot water today and didn't have to wait. Great communication and response time. David and Cole were respectful of property, considerate of the neighbors, and were nice to my cat, too. Would recommend. 10/10Randy Nino

It was a pleasure working with our plumber Martin. He went over and above what needed to be done and had a great attitude. This was not an easy fix and he made it work, with a smile on his face! Our customer service agent Kyle was so easy to work with and helped us to feel at ease. We highly recommend their services!Alex Roberts

Great service from Martin Ruiz of Plumbing Plus. We had a leak in the water pipe coming into our house and he quickly diagnosed it. He had some issues getting the parts but stuck with it and found them downtown. Once he had the parts he quickly fixed the problem. Great job!Michael Fuqua

Join Our Plumbing Plus VIP Program
Plumb Star Partner™ Membership
There’s a difference between calling a plumber when something breaks and having a plumber who already knows your home. Our Plumb Star Partner™ membership is built around that idea.
Members receive front-of-line priority scheduling for both routine and emergency calls, 10% off all plumbing services, no dispatch fees, and free estimates. Once a year, we perform a comprehensive safety inspection: a water quality test, water pressure check, leak inspection, dye testing of toilets, water meter check, water heater flush, and a sewer camera inspection of one drain. All work completed while the plan is active is backed by a one-year workmanship and materials warranty, an upgrade over our standard terms.
That combination of priority access, annual inspection, and an enhanced warranty isn’t something a standard service call delivers. It’s designed for homeowners and property managers who’d rather stay ahead of a problem than respond to one. If you’ve had a plumbing emergency before, you already know the math. Joining the Plumb Star Partner™ program is one way to change the equation going forward.
If want to learn more about the Plumb Star Partner™ membership, we’re ready to help. Call Plumbing Plus today at (858) 630-3141 and let’s get started.
