My plumbing journey started in 2005 at a reputable plumbing company in San Mateo County. I enjoyed gaining experience in service, repair, and remodels during my initial years. Those three years provided me with invaluable skills. After that, I worked for a reputable plumbing service company in San Jose, CA. After five years in the service industry, I decided to pursue a new direction. From 2010 to 2014, I collaborated with a top-notch plumbing contractor dedicated to new construction in Atherton, CA. In those four years, I developed a strong clientele in my spare time. To enhance my service to clients, I chose to focus entirely on my business, resulting in the founding of Henthorn Plumbing.
My mission is to restore that traditional, straightforward, and simple service because that’s how I operate and what quality craftsmanship embodies. Henthorn Plumbing is fully licensed, bonded, and insured. I, Matt Henthorn, am the business owner and a licensed plumbing contractor (CA #994835) who grew up in Mountain View, CA.
I cherish moments with my wife and two kids, playing music, enjoying traditional archery, and, naturally, plumbing.

Recommended Customer Reviews

We first called Matt about sewer problems. We had first called Roto-Rooter who installed a cleanup in the middle of our front lawn. When that failed, we called Matt. He determined that the problem was with the city. He helped me contact the city and arrange for a free repair.
Today I called Matt with three problems, a water heater that was turning off, and repairs to two toilets. All of these he fixed quickly.

Matt called to confirm my appointment, he was on time, explained the work to be done and did an excellent job! I would not hesitate to recommend Henthorn Plumbing!!!

Matt was called when our water heater failed. He asked me a few questions on the phone and then asked me to send him a picture of the info label on the side of the water heater. He knew what was wrong, got the serial number off of the label and showed up on time with the right part.
He had the water heater running in less than 30 minutes, cleaned up the area, and was on his way. I was very impressed.
He's polite, showed up on time, and very professional. I asked for his card and will use him again. I highly recommend Matt.

We've had Matt out to the house numerous times for plumbing issues. He always does great work, and gets the job done quickly too. He will continue to be the first call we make when we have any plumbing related issues. Thanks for your hard work Matt!

Matt was professional, responsive and reasonable. Overall excellent experience.

I looked up a plumber on Yelp and found Henthorn Plumbing. I called one other company, but I really liked Matt's manner on the phone. The other company I called started throwing out all kinds of caveats: we may have to go on the roof ($), etc, etc.
Matt Henthorn knew what the problem was from my description, and said it would probably be an easy fix, which it was. His price is very reasonable, he showed up on time, and got the job done. Solid 5 stars, and we will use him for our future plumbing needs.

Had a clogged toilet and was looking for someone to come in as soon as possible. Tried a few other plumbers and nobody bothered calling back. Called Matt at 8:15 AM, got his call back by 9 AM. We scheduled a time for later in the evening.. and as promised, Matt was right on time, got the toilet unclogged, fixed another minor issue. Less than 15-20 mins, he's done a thorough professional job at a reasonable price and left a very happy satisfied customer. Will definitely reach out to him anytime I have plumbing issues in the future and also recommend him to others.

I called Matt to clear a clogged toilet. Matt quoted $125 to clear the line between the toilet and the septic tank. I chose Matt because the other plumbers I called quoted $200, $250 and $338 to do the same job. Matt provided quality work and left the bathroom cleaner than he found it. He charged exactly what he quoted. He is professional, honest and a pleasure to deal with. I will definitely call Matt for my next plumbing job.

In my search for a highly capable plumber to replace a badly leaking water heater, most of those I contacted either didn't return the call or failed show up at the appointed time. Matt, however, set himself apart from the others. He was responsive, on time, and as we learned, a talented plumber who takes pride in his work. He's also a skilled listener, intent on gaining information that is or might be important to his diagnosis. While he works efficiently, he doesn't cut corners and spends a good amount of time carefully inspecting and testing his work. The installation was an improvement over the unit being replaced both in workmanship and approach. For example, the old heater, while strapped to the wall in such a manner that would permit lateral movement in significant shaker. To mitigate that possibility, Matt added wood blocking affixed to the wall to provide more stability in an earthquake. Additionally, he replaced the screw type water valve with a single lever type which provides an added measure of safety with its ability to quickly shut off the water source. It was a high quality installation.
Aside from the attributes I mentioned, we found him to be honest and respectful. There was never any up sell, I'll be calling Matt for my future needs.

My water heater cracked and leaked all over my basement on a Wednesday night. I called Matt for an estimate. He came by Thursday morning and immediately shut off the main valve to the water heater (it was stuck). I had 3 other people come in and none of them would touch the valve. Matt's quote was very reasonable to replace my existing tank water heater with a Navien tankless water heater with re-circulation pump. I chose Matt to install the tankless water heater as he was the most genuine, honest and trustworthy plumber I met. He gave me various options and gave me all the pros and cons.
Matt immediately replaced my water heater on Friday and hot water was running immediately. The wife and kids were ecstatic and life was good again. He then came by the following Friday to finish the re-circulation pump throughout the house and also replaced an old toilet with a new Toto one. He took care of all the old pipes and old water heater and left me with a nicely installed tankless heater.
It's been about 2 months since my water heater was installed and we love it. I highly recommend Matt and will call him up for any future plumbing projects in my house. He was always on time and I never felt like I had to worry about a thing. I don't think I will ever call another plumber.
