I began my plumbing career in 2005 with a respected plumbing firm in San Mateo County. I enjoyed gaining experience in service, repair, and remodels during my initial years. I gained essential experience during that time. My next position was with another prominent plumbing service in San Jose, CA. Following five years in the service field, I knew it was time for a new challenge. From 2010 to 2014, I worked with an outstanding plumbing contractor focused on new construction in Atherton, CA. Throughout that period, I established a loyal client base during my off hours. To provide better service, I resolved to dedicate myself fully to my business, which led to the establishment of Henthorn Plumbing.
I aim to bring back that classic, no-nonsense service because that’s my approach and what true craftsmanship represents. Henthorn Plumbing is completely licensed, bonded, and insured. I’m Matt Henthorn, the owner and a licensed plumbing contractor (CA #994835), raised in Mountain View, CA.
I cherish moments with my wife and two kids, playing music, enjoying traditional archery, and, naturally, plumbing.

Recommended Customer Reviews

This is a long overdue review. I needed a plumber to relocate a vent going from the kitchen sink drain, because the vent was in the way of a new window that was being installed. My contractor referred me to Matt. I found him easy to work with, very skilled and quick, and not one to try and rip you off just because it's boom time for remodeling work in Silicon Valley.
What more can I say that other people haven't said except that Matt is a gem of a plumber.

I had a couple of plumbing problems and called Matt again. He responded quickly and arranged a time the same day for an appointment. As always Matt came on time and looked over the problem. He was able to fix one quickly and obtained parts and returned to fix the second problem. We decided to install new low flow toilets which Matt ordered and picked up. A day or two later Matt installed them . As a true professional, Matt tries to keep my expenses low , works very efficiently, and always is respectful of his surrounding ( Neat and clean ). I can highly recommend Matt in every way.

Matt installed a new water-efficient toilet (Toto) in our older home. He helped us understand the options, arrived on time, and installed the toilet carefully and efficiently. We recommend him to others, and plan to call him again the next time we need plumbing work. (Our next-door neighbors recommended him to us.)

I highly recommend Matt. We called him to fix a clogged drain and he happened to be in the area so arrived within 5 mins of our call. He was super nice and fixed the problem very quickly.

We had a clogged drain, when I use washer the water would come back up from the shower tabs and we were not able to use toilets for few hours before the water went down. I had one guy came over said we don't have clean out for our house and he needs to dig a big hole on my front lawn and he will charge a lot since it is a big job. Then I called Matt since lot of people recommend him through next door, he came over right after I called him, he found the same problem but he gave a much better solution through the crawl space to install a clean out open to the back yard. Which will be a lot cheaper than digging in the front yard and looks nicer and don't need to patch the lawn afterward. He started to work on it right away in the rain today and had the clean out installed and also got my drain cleaned, everything was done in about 3 hours. I was so happy about the work Matt did and I will for sure recommend him to my friends.

Matt was terrific in troubleshooting an issue I was having with my kitchen faucet. On time, efficient, knowledgeable and reasonable pricing. I highly recommend and will call him again if I need help.

Matt did the plumbing on a complete house remodel for us. Matt was the best and easiest to work with of all the contractors we used. Not only is he knowledgable and capable in his trade, he is very responsive and dependable. He takes his commitments very seriously and is a great communicator.

Matt just installed a water return line from my master bathroom to my water heater, along with a pump. Now I have instant hot water at all my taps and showers, thus saving water waiting for the hot water to show up. Matt was timely, tidy, honest, knew what he was doing and got the job done quickly. He is also very amicable to work with. I asked Matt to re-work the pump piping to fit it closer to the water heater so my kid would not damage it passing by with her bulky metal book bag and he did it cheerfully. I recommend Matt highly. He will be installing my Ultra Low Flush (1.06G) Toto toilets when they arrive.

Matt was awesome. I discovered at 9 PM that my hot water heater had broken, and my basement was flooded with warm water. After a few basic questions, Matt was at my door an hour later with a new heater. Other plumbers might be grumpy and short in that situation, but despite the late call, Matt was extremely friendly, positive, and professional, and worked tirelessly until almost midnight to get me squared away. I really appreciated how he took the time to answer all of my questions and the fact that he respected my home, taking care not to leave a mess. This was quite possibly the best experience I've ever had with a plumber!

I Highly Recommend Matt Henthorn.
