Don't take our word for it — here's what Tri-Cities homeowners and businesses are saying on Google.

Thank you Columbia Basin Plumbing for the excellent service. We had a leak under our kitchen sink that we just couldn't locate. You were able to get out next day and take care of the problem.

Travis quickly found and fixed our water leak. But even more impressive was him crawling on his belly in a very narrow crawl space to get to the leak. We are very thankful and happy for the services at Columbia Basin Plumbing.

Just Me February 14, 2025

I had a valve on my hot water tank that needed attention in my Pasco rental. I’ve worked with Columbia Basin in the past through a previous place of employment. They are a great referral partner! Megan, the owner, was prompt with getting someone scheduled and out to the house. She’s very nice to speak with and I think Lee resolved my problem for my renters! Thanks Megan & Lee!

Lauren Heen February 12, 2025

We love this family business! They came to our rescue at our business when we needed them the most. Excellent customer service, fair pricing, honesty and integrity. Highly recommended!

Catie Sloan June 3, 2024

I highly recommend Columbia basin plumbing. Had an emergency after a pipe burst after a cold night. They were able to schedule me same day and fixed the issue with ease. Competitive prices had me charged hundreds less than I was expecting so I am especially grateful for that. Tyler was my laborer, good dude very good customer service explained and broke everything down easily for me to understand. I will definitely be calling them back for any plumbing issues in the future

Chris Maudlin September 16, 2021

This is the second time we've used Columbia Basin Plumbing and both times we've had excellent service. The first was to install new faucets throughout the house, a garbage disposal, and the second time was to install a new hot water tank. The price has always been reasonable. The guys that do the work have always been extremely professional. They have my business for life.

Denise Stafford July 30, 2021

They responded and fixed my problem quickly, and for a great price!

Aaron Phillips February 26, 2021

I was dreading calling a plumber as I have never had to. Fast, friendly, excellent work at a price less than I had anticipated.

Theresa Rainey-Slack November 5, 2020

So grateful for Columbia Basin Plumbing. The office staff was so kind and understanding and great at communicating and getting our repair scheduled on a Friday afternoon. The plumber who came out was friendly and had us fixed up in no time along with some great advice for future repairs/projects.

Aerie Rogers September 25, 2020

I can't begin to say how impressed I am with Columbia Basin Plumbing! From the first second on the phone with Megan, all the way through finishing the job, they were courteous, knowledgeable, professional, reasonable, and do great work. They handled an entire replumb for us on an older manufactured home in a timely manner at a fair price. We are 100% satisfied and will use them in the future!

Stacee Connelly June 4, 2020

I gave them 5 stars even though there was a time hang up which is understandable. The gentlemen that came out was very professional and polite. He answered any questions I had and explained what needed to be done. They do charge one hour labor minimum which is typical but they would have been done in 20 mins... So the time hang up was the service man ran out of access panels and was gone for almost an hour running around town locating one to buy. This wasn't that big of a deal with me since I had no plans, but should be addressed in the review as it could be an issue if someone was on a time restraint. Their pricing I believe is fair they where less than half the amount Mr. Rooter wanted to charge. Overall, great experience.

Misty Mixon May 29, 2019

Absolutely Amazing, Hero's I'd say, I needed my water heater installed and had called 20 other places before reaching them, by far the best customer service I've ever had, they squeezed me in the same day and got the job done! Would call them again if I ever need services. Thanks again to the Columbia Basin Plumbing Team.

Cara McKinnis May 2, 2019

I cant say enough good things anout them. They really care. They actually went out of their way to not only do a good job for a fair price but helped me deal with the results of a nightmare plumber who left me in a bad pinch. They moved their schedule around and made it happen. Theyre not just a great company... theyre genuinely caring... nice people.

Benjamin Hysjulien March 29, 2019

Tyler was professional and faced with a very complicated issue. He kept on in very trying conditions until the situation was solved. Thank you!

Nancy Marquart March 5, 2019

Awesome company! Helped me over the phone no charge until we felt we found the problem! Thanks Jason!

Dpena Larios January 10, 2019

I have used Columbia Basin Plumbing for multiple project big and small, every single time the work is completed on time and within budget. They are very knowledgeable and professional, I would highly recommend them for all your plumbing needs.

Luis Miramontes January 8, 2019

I can not give Columbia Basin Plumbing a good enough review! We had our newest grandson coming to visit our home for the first time and our water heater went out the night before. Both my wife and I were in a panic! We called Columbia Basin Plumbing and were connected to Jason. He assured us he would have everything taken care of for us first thing in the morning. Jason came out to our house at 8:00 the next morning, (a Sunday on top of all of this,) diagnosed, changed out, cleaned up, and left in under two hours! Not only was the customer service fantastic, the price was less than half what we expected. I wholeheartedly recommend Jason and his whole team at Columbia Basin Plumbing for whatever plumbing needs you have! We are very thankful to see there are still those contractors out there willing to sacrifice their personal time to make sure their customers needs are taken care of.

Angelo Ciulla January 8, 2019

They were able to send somebody out the same day we called. The plumber, Tyler, was on time, fixed my issue, and was polite and courteous. The pricing was clear and fair. I would recommend them and will use this company for future issues.

Maria Bultena January 2, 2019

They were prompt, and understanding of our situation.

Kyle Bettencourt December 31, 2018

Best plumbing business in tricities!

Liv Vahn December 23, 2018

Spoke to Donna and she was super attentive to my situation and scheduled an appointment for the following day. Next day Jeremiah arrived on time and went right to work figuring out the toilet drain back problem. He was excellent and worked fast and was extremely knowledgeable about what was being done. For a bad situation it was a pleasure having Jeremiah figure it all out and great attitude. Thank you Columbia Basin Plumbing.

Ryan Wright June 30, 2017

Megan and Jason are by far the most professional and efficient business owners I've met in a long time. Each time we have called them to our house Jason has been there within the day or two. If somthing comes up Megan is quick to stay in touch as to when they will be out. I completely trust the work they do as well as their word and that says a lot. If your looking for honest, proficient, affordable work. These guys put they're whole hearts into what they do. Look no further!!! Thanks for everything, Maraiah and Justin

Chevy Girl August 20, 2016

My husband and I were in the middle of moving and had our shower head break off in the wall and we just didn't have time to fix it our selves... Everyone else my husband called couldn't be to our old house to do the repairs for a few days and we just couldn't wait that long... We called Columbia Basin Plumbing and they were able to be out to the house within a few hours and had it fixed in less then an hour... Very friendly and professional!! And his rates were very reasonable!! They will be our first and only call of we ever need someone again!!
