I found Core Plumbing through Yelp because I had a kitchen sink leak issue that has been an issue on and off for months and has just gotten worse. Core Plumbing did a free estimate and I also appreciate the transparency. Kevin was very professional, friendly, and helpful! He explained what was wrong, what he was doing, and why, which I truly appreciate. They ended up fixing the water pressure (which was reading at 82 versus the 65 that it should be), replacing the air gap, the air admittance valve, and replaced the piping that was previously glued (so if there is blockage, we can easily remove and clear the pipe and put it back on). He also advised of additions that would be helpful, but did not try to oversell me, which I appreciate and have written down his recommendations. The work was done within the day and I couldn’t be happier, a bunch of stress off the shoulders - thank you, Kevin, and Core Plumbing! Would definitely recommend (pictures are before and after)!

Core Plumbing was absolutely fantastic. They came out to replace two shower valves, and the entire experience—from scheduling to completion—was smooth, professional, and stress-free. The technicians arrived on time, respected my home, and communicated clearly about what they were doing and why.
What really stood out was the quality of their workmanship. They handled what could’ve been a complicated job with total confidence and efficiency, and the final result is flawless. Everything works perfectly, and they left the space cleaner than they found it.
It’s rare to find a team that brings this level of skill, care, and professionalism to the table. I’d recommend Core Plumbing without hesitation to anyone needing plumbing work done right the first time.

Our shower head repair was handled in a professional and timely manner for a fair cost. The repair professional Joe handled things perfectly and was very nice. I even got to meet the owner Don who had an amazing tool that came in handy at the time. They also offered ideas when we decide to do renovations to the bathroom, and that they could do the work in the future. Highly recommend.

Quick and friendly service. All techs were very professional. They took the time to carefully explain all the work needed and potential areas of concerns to address as well. Very happy with the repair work.
Adding to this as they had to take care of some additional work items for me. Plumber was again, very friendly and thorough in his work. Superb job on installing new PEX piping, regulator, and washer box.

My insurance company raised my deductible to $10,000 unless I installed an automatic water shutoff valve. I called Core plumbing. Grant came out the same day and provided an estimate. I accepted it and work was completed the next day. The plumber and helper were quick and clean leaving a tidy installation.
