Micah and the boys squared me away on some plumbing rerouting I needed done before a big bathroom remodel. They were informative, and even went above and beyond by giving me advice about products and remodel ideas with their insider knowledge. I will for sure use the again in the future.

On time worked quickly and updated when he knew what the job included. Kevin was easy to talk it over with, had answers, and knew 100% what he was doing. He let me know the potential worst case but then did his best to have it be the simple fix. He also went above and beyond giving a helping hand as he came in on … not even his work! I appreciate good people like him a lot. You have my wholehearted referral to friends and neighbors any 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.

Service was fast, effective, professional, and friendly. The team arrived on time and the ability to schedule appointments and track their arrival online was fantastic. My only qualm is that the cost of a drain cleaning visit ($517 for less than an hour’s work) felt unreasonably high.

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.

I called them as a second opinion on a stuck bathtub. The previous plumber had recommended opening the dry wall or digging up the floor. Core cleared the blockage in a half hour with none of that. Really appreciate them.

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)!

If you need help with a plumbing problem, you can't go wrong reaching out to Core Plumbing for help.We recently had to have our water service from the street to the house replaced, which of course meant digging a trench across the yard. I knew that the plumbing work would be top notch when I called Core, because we've had them handle a couple of other significant jobs that went really well.What I didn't expect, though, was what a great job Core would do minimizing the impact on the yard from the trench work. You can hardly tell a trench went through the yard just over a week ago!Many thanks to Grant, Joe, Josh, and David for a job really well done.If you need help with your plumbing and you're not sure who to turn to, give Core Plumbing a call . . . I know I'm glad I did.

Core Plumbing was excellent! Tony Halvorson and David Ortega replaced a faulty regulator running at 80 PSI and swapped out a toilet tank upstairs. The app and text updates made it easy to track estimates and arrival windows, which gave me peace of mind while helping my elderly mom. Prices were standard, the service was honest, and the whole process was smooth and professional. Highly recommend!

Do you know a great plumber is hard to find?We found one, actually two, Kevin and Jordan at Core Plumbing!Our relatively new, hybrid water heater never seemed to have hot water when we wanted to shower! It was a constant, frustrating issue! Our neighbor told us about Core Plumbing and they came took a look, diagnosed the problem, and the best part is they took the time to explain the problem to us. It was a faulty, 25 year old pump and missing check valve. They did a great job fitting a new one into the system. They were professionals from start to finish! Fair, fast (completed to job in about an hour), and professional! We highly recommend Core Plumbing!

Everything from Gas Range install, Tankless Water Heater, Washing Machine Connections, Outside Faucet Leak, Jones Valve replacement, to the inner guts of the toilets. Everything that these guys do is professional. I have worked with Grant and Tony on several of these jobs. Trust me, Core Plumbing is as good as it gets.

Our 31 year old main water line from the meter to our garage had a pin-hole leak near the meter. Core Plumbing was one of three bids to replace the line. Their bid was in the middle, but they were the most professional in assessing the job. We saved some money by having our landscaper dig the trench to Core's specifications. I was impressed that Core Plumbing insisted on providing the sand to protect the new 1 inch PEX line and do the backfilling and compacting. Communication with the company was excellent. Our crew of Greg and Eli showed up on time and were very conscientious and skilled. I would highly recommend this company and will use them again when the need arises.

Core Plumbing were extremely efficient and very generous with their services.I was on a time crunch to get my water softener disconnected and removed before the garage flooring was to be replaced.Kevin came the next day first thing in the morning, disconnected it and provided a blanket so it wouldn’t damage the floor and moved it into the house.Then when they came back, they provided plastic covers to make the garage wires look more appealing. And the 2 guys that came quickly moved back my water softener and reconnected everything back. Made sure it worked by having me turn the water on, etc.They cleaned up their work space (Kevin wiped down my water softener too because it was covered in dust) and were all very polite and professional.Highly recommend! Thanks so much!
