I've been a customer of John's Plumbing for a number of years. His plumbers have done a number of small jobs and one large job for me at my home in Novato. All were done with good attention to detail, quality work and at a fair price. The most recent large job was very complicated but his team did perfect work. Employees are friendly and reliable. Would use their services again and recommend them to others.
John, the owner, is good about keeping on top of the projects and keeping customers informed about any needed info.

I had an old dripping shower with washers that were always failing. After talking to a variety of plumbers, I chose John's plumbing to cut into my tile and replace the valve. Ruben did a great job. Although their hourly rate is a smidge higher than average, I saved quite a bit because Ruben was so efficient.

Then, when being told the house needed a costly sewer lateral job, John gave a passionate dissenting opinion which was corroborated by a few other professionals. Saved me again.

It is my pleasure to recommend John Gleason's Plumbing & Sewer Service. Yesterday was the 3rd time we used John's assistance. It's ALWAYS a stressful situation when something backs up in your plumbing and begins to reenter the toilets, showers and bathtubs...add that it's in an 60 year older home with a 92 year old Mom and the scene intensifies. From Mary and Erin in the office to the wonderful workers who came to rescue me from the ugly scene, they are courteous, professional, and kind AND they solve the problem! I simply would not hesitate in calling John Gleason and his plumbing & sewer service. They were terrific!

I am not officially a customer of John's because I haven't paid him anything! Let me elaborate... I called with a major plumbing emergency on a Sunday afternoon and John was off visiting his grandchildren. He actually walked me through how to get my problem fixed!!! I had him on the phone for at least 10-20mins when he shouldn't have given me the time of day. He was a kind, thoughtful, and caring man! I will definitely use John's plumbing in the future.

Just had John and his guy mike out to the house to fix a hot water leak after my contractor drove a nail through the pipe. Again I would strongly recommend John Gleason for any of your plumbing needs. He has now done multiple jobs for me and is extremely easy to work with. I will be only using him for all future plumbing needs.

We have used John several times. Each time has been great. The first time we called the day after Thanksgiving, with a problem we thought might be an emergency, we explained the problem over the phone, he gave us an explanation and he came out the next day and took care of the problem.

He has helped two other times - both were those emergency type calls. The last time he took the call in the evening and was able to help us over the phone.

John is now my go to guy for our plumbing.

Not only is John a stand up guy, he and his crew do great work. He is old school, which means he does quality work for a fair price. He will tell you honestly what you need and don't need. He helped me out by fitting me into his schedule even though I didn't give him much notice at all. I could not be happier with the work that has been done. I am extremely greatful to him and his guys. Highly recommend!

John was great. I had a faucet with a leak in the valve. I called him, texted him pictures of the faucet, he found an exact replacement and installed it the same day it arrived from the warehouse. This was all within 48 hours which was appreciated as it was our kitchen sink. He followed up afterwards to make sure everything was good. John was top notch and I would certainly use him again.

Friendly, honest, quick to come out (like less than an hour), found & fixed the problem fast; John Gleason Plumbing was a pleasure to work with. When you have an emergency and your business relies on having equipment that works, toilets that flush, absolutely NO backups and a very very quick response time John is who we call.

For the most part we use our facilities personnel to fix minor plumbing issues but when some plumbing catastrophe happens we need the extra reassurance that come from a reliable plumber who is insured & boned. We have shopped around for a plumber that can basically come immediately when called for an emergency plumbing situation, as a medical facility we needed a reliable partner that is as committed to us as we are with our clients. John has so far showed us that he is our man and we are grateful for his professionalism, quality work and speediness.
