Plumbing reviews in Covina, California

If you are looking for a plumber I would highly recommend Courtesy Plumbers. Aaron came out, he quickly diagnosed the problem and explained everything in detail. The job was done quickly and professionally. The price was reasonable.

Jack was here 9/29/2025 to repair my water pipe. He did an amazing job. So quick to get job done. So thankful.

Jack came over to inspect a possible leak in my home. He was very professional and explained possible causes and solutions to the problem that I had. In the end, we were able to identify the cause of the “leak” and turned off the water to a rarely used toilet. Easy fix!

Excellent work! They showed up on time and did exactly what they said they would. There prices were also cheaper than other vendors. Highly recommended.

Had a backed-up sink and called for service. Got a same-day appointment, and Johnny the technician was greatquick, professional, and efficient.

Jack is very professional and did an excellent job replacing our water pressure regulator. Highly recommend Jack and his company.

Courtesy Plumbing was highly recommended by a good friend. I'm a former Vietnam veteran who was given a discount from the company. Johnny Taylor, our plumber was very professional and did an excellent job in unclogging our kitchen sink. He did not try to add any other task that was not necessary. He had the "clean as you go" attitude which was very impressive. My wife was extremely satisfied with his work. We called a couple of other plumbers but the were very expensive and/or unavailable. Courtesy Plumbing responded immediately. We were impressed. Like my friend before me, I too highly recommend courtesy Plumbing for all of our future Plumbing issues

We've used them a few times now. Had a gas leak on our furnace hookup that we noticed. They came out on the same day we called and were able to replace/fix the part. Highly recommend. Thanks Cory!

Aaron was here right on time and was very helpful and polite. We needed a plumber fast and on a Saturday. They were here within 2 hours and for a very reasonable price. I will definitely be keeping their number!

Aaron and Jacob were awesome! Very professional, knowledgeable, and friendly. So happy with the service we got and today.

I would highly recommend Courtesy Plumbing. I will be calling them the next time I need a plumber. I had a very simple problem with my toilet, but two plumbers before Jack and Courtesy Plumbing had come and gone (and charge me for their visit) yet still the problem persisted.

This morning, Jack called to let me know he was on his way. He arrived promptly. He was very friendly. He took the time to show me what was wrong how, he was fixing it and why the repairs in the past had not worked. The entire process took less than 15 minutes! The fee was less than I had been expecting. II can’t recommend Jack and Courtesy Plumbing highly enough.

Always a great experience with Courtesy plumbing. Our place is old and Richard and Jonny were informative and helpful with answering our questions about our home’s plumbing supply issues and future needs to prevent further problems. The task at hand they came for initially, they were able to provide ultimate satisfaction in their work.

Jack came out on short notice and on time he called me to say he was on his way, we needed a new water pressure valve he had one on his truck and he had it fixed in under an hour. l will definitely be using Courtesy Plumbing for any future needs. JKeehn

I contacted Courtesy Plumbing for the first time based on their online reviews and ratings, and I’m happy to say they truly lived up to them. My first impressions are: Timely, Courteous, Efficient, and Professional — and as someone who is retired from the trades, I can confidently say these descriptions are well deserved.

My initial phone call was very pleasant, and I was able to secure a same-day consultation and proposal to evaluate my water pressure valve. Richard arrived exactly when they said he would. He was a pleasure to speak with — very honest and straightforward. The price quoted was fair, so I gave the authorization to move forward.

I was contacted the next morning and was pleased to see that Richard returned to do the work himself. This eliminated any concerns about getting a different installer or a “bait and switch.” Richard completed the job efficiently, provided a clean and professional install, and used high-quality parts.

This was my first experience with Courtesy Plumbing, but they’ll absolutely be my first call for any future plumbing projects. Highly recommend!

Courtesy plumbing is a great plumbing company. Cory and Aaron have been fantastic to work with and are always available when I need them. They go above and beyond to diagnose and fix the problem. A few years back I had a major leak in the pipe below my kitchen and bathroom on a weekend and Cory and his crew worked the whole weekend to dig up the kitchen floor and bathroom floor to fix the problem. It was a tremendous amount of work and they did a great job!

Richard took great pains to explain what he proposed to do for both our toilets. While the one was not making the water-running noise--naturally!--he explained that should the sound come back, Courtesy Plumbing would return to fix. With the second toilet he explained what was likely the problem (a wax seal) and then, while restoring that, he noticed that the leak was more extensive than we thought, suggesting a restoration company that Courtesy has worked with before.

I would call Courtesy again--this was a very pleasant experience--and recommend to any who needs plumbing.

Cory and the crew are always professional and able to handle any task at my workplace. They always show up on schedule and get the job(s) done promptly. Scheduling is a snap due to their excellent office staff. I highly recommend courtesy plumbing for both residential and commercial plumbing needs.

Was very happy with the service provided by Courtesy Plumbing and their serviceman Jack who came to address my issues. Jack replaced a 20+ year old pressure regulator that was bad. Professional and prompt work.

I want to share this review of Courtesy Plumbing and their worker Jack. I needed my water heater repaired and Jack came out and first explained the problem and discussed options. He made the necessary repairs and the work and his expertise is exceptional. I highly recommend Courtesy Plumbing and if you can ask for Jack, you won't be disappointed. He is courteous and knowledgeable.

WOW!! John showed up on time and with a smile. He introduced himself, asked me to show him the problem and got to work. Cleared the clogged kitchen drain in less than 10 minutes.

As the name implies, he was quite courteous!

I highly recommend Courtesy Plumbing! They don't try to gouge you and advise that work needs to be done when it does not. Value, definitely! Honesty, without a doubt!

Make Courtesy Plumbing your first call!

Thank you John!!
