Recommended Customer Reviews

Joel and Martin were very helpful to me. They saved me hundreds of dollars. They seem very knowledgeable in water heater systems. Martin was on time and very respectful and quick with his repair. He knew exactly what to do to get my water heater back up and running. I definitely recommend this company.

Joel did an amazing job navigating a challenging situation involving a replacement of a broken main water valve and a leaky pressure breaker valve in tight quarters. Regardless of the time, effort and challenges; Joel pushed the project through to a successful completion (likely when most folks would have ""tapped out"".) His work ethic, integrity and skills are top notch and I whole-heartily recommend his services to anyone.
Thanks Joel!

Fixed our main water line and put and attached a drain to the dishwasher. Did a good job at a reasonable price. Very flexible.

Joel installed whole house water filter/softner us, and also installed the under the sink reverse osmosis filter. He beat every single price quote in the bay and did excellent and professional work. He was friendly, knowledgeable and very accomodating of every question I had during the process. He even accepted impromptu requests I had to fix other plumbing issues in the home. He will be the first person I call anytime I have any plumbing issues in the future. And I highly recommend him.

Joel is the independent business owner. He responds promptly and responsibly. I called him for an appointment, he came over right away next morning for the job. Today he finished my little project efficiently and neatly: removed old and installed in 3 new toilets. He was very professional, pleasant, courteous, came across very confident due to his experiences in the plumbing trade. On top of good work, his price quote was fair and reasonable to go along. I was very pleased to have chosen Joel to do this project. If I ever need a plumber in the future, I would definitely try to reach out to him again.

Working with Joel was fantastic. He helped me with my San Jose property. He was beyond flexible, affordable and very professional. I was out of the area and I was able to communicate with him all over email/text. We talked communicated prior to the job and he even followed up with me days after the job was completed. I will be using him again in the future. Highly recommend.

There great other plumbers told me 1200 they came out and did the job $150 gave them $50 tip honest people won't go anywhere else.great people

Joel is a professional backflow expert. He repaired the equipment which other contractor said not fixable.

They quoted me low to get the job, removed my shower's handle and then tell us that the cost will increase from $180 to $225. This is bait and switch tactics. Don't fall for them.

Joel did a great job replacing the drain line on the kitchen sink. Extremely reasonable price, professionally done. Will use again and recommend to any of my friends.
