Plumbing reviews in Bothell, Washington

Kajik Zaghian arrived promptly and was ready to troubleshoot my issue. He was able to quickly determine my issue and then crawled into a horribly tight crawlspace. Then he left for about an hour, purchased the required parts, put it together properly and installed it very quickly. Also took the time to verify everything went well and gave me all the support I needed. If I have issues in the future I will absolutely reach out to Kaizen again!!!

I am so appreciative of the work done by Kaisen after my grandson flushed a dog ball down the toilet. They came back a second day,after I bought a new toilet, and finished the job for the same price. I will be paying higher attention to my grandson during his potty training.

Kajik and friend was great! Assessed and replaced the sump pump in less than 3 hours. Also gave me maintenance advice. Thanks Kajik/Kaizen!

Kajik is very easy to communicate with, professional, always responsive. He showed up no matter how late or how early when my kitchen pipes had issues. Highly recommend!

I had an excellent experience with Kaisen Plumbing, thanks in large part to the professionalism and expertise of our plumber, David. From the outset, David demonstrated outstanding attention to detail and a commitment to customer satisfaction.

During the service, David discovered an additional leak that we weren’t aware of. Instead of overlooking it or charging extra, he promptly fixed it free of charge. David also pointed out damage to our baseboards caused by the leak, something we had not noticed.

To ensure easy future access to the plumbing, the installation of a quick-access panel by David was a thoughtful solution that will save us time and money on potential wall repairs and repainting.

On top of the excellent service, Kaisen Plumbing also provided a $50 discount on the initial quote, which was an appreciated bonus.

In conclusion, my experience with Kaisen Plumbing, and particularly with David, exceeded my expectations in every way. Their service is all about attention to details and customer-oriented. I highly recommend them to anyone looking for a reliable and conscientious plumbing service.

Plumber came to do an estimate of the work required to fix my under the sink water filter system. They didn't find any clear issue and recommended replacing the whole unit.

However, as they investigated the problem, they removed the hose that goes into the system and reinserted it, and the unit is now leaking from that place - when it was not leaking before their visit. So unfortunately they actually damaged it in the process.

Kaizen Plumbing Review
After receiving notification of a water leak on our property, my husband set out to get three estimates. Kaisen Plumbing was the first to respond and provided the lowest estimate. They began work four days later and completed everything by that evening.
We were impressed with the saw cut on our driveway done by
Mohammad Ranjbaran which was quite clean and precise.
They installed new Pex pipe and also managed to expose our water shutoff valve for our irrigation which Kajik Zaghian had notified us, had been buried under the concrete. We also appreciate laborer Elias Pezez and the men for all the labor intensive digging that had to be done. Overall a very hard-working and focused team and we were quite impressed with the quality of their work.
My husband was interested in having our shutoff valve relocated to inside the house rather than out in the driveway. Upon notifying Kaizen Plumbing of the issue, Kajik said they’d be back out to take a look at it in a couple days. Not long after, receptionist Suzie also very pleasant, notified my husband they’d be able to send someone out that same day.
Mohammed and Elias came back out and reconnected our irrigation from inside the house. They worked an additional 3 hours to complete this work and Kaizen Plumbing included it in the original bid, adding no additional charge.
We would strongly recommend them to anyone looking for a competitively priced, prompt, and efficient plumbing company to service their needs.

After an early morning call to schedule a service call later that day, I was promised a service visit starting between noon and 2pm, with a technician to call when on the way.

I know how things can go, but by 3:20, not a peep. Nothing. No update or status. Diddly.

I called them. They contacted their guy, and called back to let me know they'd have to reschedule for 3 days later.

I get it. Things happen, but keep your customer informed. I wasn't up at 5:30am looking for service for 3 days later.

I will offer that their automated call answering thing is top notch - one of the best I've ever talked with. Really! It's outstanding.

But it's making promises the company can't keep.

I cannot comment on the quality of their work since they didn't do any. Customer care is unacceptable.

The best and professional company that we’ve ever worked with. Our water heater started leaking at night and Kajik the owner of the company came out 10pm to fix it to prevent further damage to house without charging any additional emergency charge . Will recommend this company for anyone looking any kind of plumbing issues and repairs.

If you have a plumbing job and landed on Kaizen Plumbing page, consider yourself lucky. And if you're reading my review, consider yourself even luckier—because you don’t need to look any further!

I had the pleasure of working with David from Kaizen Plumbing, and I couldn’t be happier with the service he provided. He helped me replace a leaking water heater tank and went the extra mile to install a smart water shut-off valve as well.

From start to finish, David was transparent, professional, and extremely knowledgeable. He took the time to walk me through every step of the process, ensuring I understood what was being done and why. Unlike many other plumbers who just throw an overall price at you, David was upfront about every cost—materials, labor, everything—so there were no surprises. Having called multiple plumbers before choosing Kaizen, I can confidently say their pricing is very reasonable and they stand by their quotes.

Beyond his technical skills, David was an absolute pleasure to be around. Always smiling, always helpful, and genuinely invested in making sure everything was done right. Even when we faced a challenge connecting the smart shut-off valve to the internet (something outside his scope), he stayed with me, offering support where he could. That level of dedication speaks volumes about his character.

Everything was installed cleanly and professionally, and I’ve attached photos to showcase the quality of his work.

If you need a plumber you can trust, who will explain everything clearly, charge fairly, and deliver top-notch work, Kaizen Plumbing and David Stuhr are the way to go. Highly recommended!

I'll highly recommend Pars plumbing! Very professional and on time. They connected the gas meter to my house and also the gas water heater insulation and connections. They also pointed out an issue with my kitchen sink drain and fixed the entire line. They came on a weekend also because of the urgency.

I hired Iman for a plumbing issue and he showed up on time, explained the problem clearly, and fixed it quickly and efficiently. He was knowledgeable and experienced, and the prices were reasonable. I highly recommend Iman for all plumbing needs.

I experienced a water leak problem, and the wood supporting the sink was in poor condition as well. Pars Plumbing demonstrated exceptional professionalism. He quickly identified a solution within minutes and completed the work the following week in just three hours.

As a contractor I have been worked with Iman for last two years. He is amazing man Always on time, fair price, ver responsive and his job is guaranteed. Highly recommended for home owner and contractor who needs Plumber with great job and fair price.

Very professional and on time. We are very pleased. We hired Pars for installation of a water heater. They did a fantastic job. I would highly recommend them for any plumbing needs.

Ian came the next day I called him to fix the clogged kitchen sink. He used the drain snake first and then went to the crawl space, cut the pipes and cleared them. It took him one hour and half to complete everything. He also helped us to investigate a leaking bathroom which turned out to be tiling issue. Love it and will recommend to friends.

I used pars plumbing for 2 time and I’m so happy with that company.
He is on time and professional And update me everything and then they are knowledgeable and they know what they’re doing. I am so lucky to find that company. I will recommend that company to all my friends and family.

Iman did a fast and great job of diagnosing and replacing a 1/4 turn valve with a cracked housing. Would recommend this plumber to anyone. Was also super friendly and knowledgeable.

I had a leakage from dishwasher. I called Pars plumbing yesterday and he came to my home this morning. and found out the problem. He also took a video of the leak so I can show to the insurance company. He did a good job and response quickly. thanks a lot.

Got a gas line and gas cooktop installed by Pars plumbing. Free quoting, very competitive pricing, punctuate and great work. Passed city inspection with flying colors. Finally found a goto plumber. I highly recommend Pars Plumbing. 10/10

I recently hired Pars Plumbing to install an under sink reverse osmosis (RO) filter system in my kitchen. I was very impressed by their professionalism, punctuality, and quality of work. They arrived on time, explained the process and the benefits of the RO system, and completed the installation in less than an hour. They also cleaned up the work area and tested the water quality before leaving. The RO system works great and provides me with clean and fresh drinking water. I highly recommend Pars Plumbing for any plumbing needs. They are reliable, courteous, and affordable. Thank you Pars Plumbing for a job well done!
