Kratzer Plumbing
Company Overview
Kratzer Plumbing began its journey in 1986 in Belmont, California. In 2005, Lee Kratzer acquired the business. He combined the current business with Kratzer Plumbing. A Los Altos native, Lee has been in the trades since he graduated high school in 1983. He became part of Triple A Plumbing in 1987 and gradually advanced through the company. He stepped down as general manager in 2005 to launch his own venture, delivering high-quality plumbing services to the Bay Area Peninsula. As a dad of two, he emphasizes the importance of workmanship and a strong work ethic, lessons passed down from his father. You might often find one of his kids working alongside him. At Kratzer Plumbing, we focus on delivering quality work by skilled professionals at reasonable rates. I wear two hats as both the owner and the sole employee. I hope to bring on additional employees down the line, but I will not trade quality service for more calls. My goal is to provide every customer with the finest service they’ve had. My background equips me to tackle challenges that could confuse other plumbing professionals. An avid surfer, I am committed to protecting our oceans and waterways.

Recommended Customer Reviews

Called them based on all the great Yelp reviews. Cleared a sewer line that Palo Alto Plumbing had cleared but clogged again in just a couple of days. Not the cheapest rates but worth it for great service. Sewer line is still clear after 1+ months.

Had a guy come out to replace 3 toilets, 2 sinks and clean out a shower drain pipe. He did a great job and was very quick. One of the toilets was broken upon delivery so he helped me pack it back up to be shipped back and replaced; at which time he came back out to install.
The one thing that he could have done to go the extra mile was advise/help with cleaning/painting the spot behind the toilet in between removal and installation. The originals left a spot that could be seen when the newer narrower toilets were installed which was difficult to get to after installation.

Just had Lee from Kratzer Plumbing to the house today. He is an honest guy. Had to have my Franke water dispenser fixed and he was upfront that the replacement parts that Franke sent me might not work. He said the job wouldn't take the full hour so if there was other things to look at he could do that too. I'll be calling him from now on. 650-571-5580

Another happy customer. They answered the phone the first time I called and were able to schedule an appointment for a non-emergency within two business days and gave me a 2 hour window in which they would show. On the phone, they did some diagnosis (I sent a few iPhone photos of the items) so I could go out and buy the parts to make the process faster and less expensive. When they showed up, everything went smoothly. They even advised against doing something we planned on doing and suggested how we could solve the problem less expensively. Repairs included: Replacement of faucet stems and multiple stoppers, replaced shower head, replaced kitchen faucet, caulked shower, installed hot water recirculator, replaced toilet stopper. Highly recommend!

I called these guys because I had a leak under my kitchen sink, one side of the kitchen sink that wasn't draining, and two toilets that weren't flushing correctly. The first company I called wanted over $50 just to come to my house. Whenever I see companies charging just to show up I think they're either not confident in their appearance (maybe they show up out of it or scary or something?) to the point that I'm too freaked out to hire them, or that they give outrageous quotes just so they can collect a quick buck and then spend all day going from house to house getting paid to do nothing.
The second company I called said they'd call me back but never did. Kratzer was a different story! They were able to send someone out the same day (Luis) and he worked so fast I couldn't believe it. I was heating up my lunch when he arrived, and when he left it was still warm. Clearly he knew what he was doing. I'll be calling Kratzer Plumbing again.

Wonderful experience! Lee came and fixed all three if my broken toilets quickly and competently. They were in touch in advance to get pix and model numbers so they knew which parts to bring. They were a pleasure to work with and I will definitely call again.

The Kratzer team is great. They respond quickly to inquiries, work with you quickly to schedule times to perform service and their service team is efficient and very nice. I highly recommend them.

Lee and Marion rock! After thinking we had figured out why our kitchen sink was leaking and having a temporary fix for it, I opened up the cabinet under the sink this morning to find a flood. AHHHHHH!!!! Such a bummer. I called a few plumbers and got voicemails, but was very happy to finally have my call answered by Marion at Kratzer Plumbing. She was so helpful and was able to book me an appointment for just an hour later! Lee and Marion came together and worked as a team to figure out and fix my sink. Lee is a straight shooter...no BS. He even spoke to my protective Dad on the phone and explained things, which was much appreciated because I do not understand plumbing-speak. My Dad had been trying to fix the sink and was going to try to fix what we thought was the problem the next time he came to visit from out of state. Marion is very friendly and happy. Such a pleasure to work with these two. I highly recommend them!!!! I also thought their pricing was extremely reasonable!!!!

Lee & Mary came to our house three times to try to fix an issue with our bathroom sink. Lee & Mary were always prompt and very professional. Unfortunately, the problem could not be fixed without shutting off the water in our building (and the valve was broken so it could not be shut off). Lee & Mary refunded us what we paid them for their first two visits and did not charge us for the third because they could not fully resolve our problem. There are few service providers out there with this much integrity. I highly recommenced that you use Kratzer Plumbing for all your plumbing needs!
