I had a leaking water valve that connects the lawn irrigation system to water mainline. They responded to my quote request quickly and got the valve replaced in the next working day. Great service.

Cal tech plumbing did a wonderful job on installation of a new vanity. Travis was very helpful in helping me find the right product. I would recommend them highly

I could not be happier with Travis at Cal-Tech plumbing. We've had him work on two projects in the house now: Installing a vanity in the upstairs bathroom, and a whole remodel of the downstairs bathroom. They're a little pricier than some of the other plumbing companies I've researched, but they're also all-inclusive. They will do all the patching, painting, and disposal associated with your project - including a very thorough cleanup of the job site. On top of that, I have twice seen him reinforce and upgrade parts of my project when he felt the factory default items were not up to his high quality standards. They stand behind their work 100% and I could not recommend them more highly!

As part of a major remodel of my house, Travis and Cal-Tech Plumbing installed new sewer lines, new gas lines, new water lines, new tankless water heater, new bathroom fixtures, and new kitchen fixtures. They provided high quality workmanship and were friendly, courteous, professional, fast, trustworthy, timely, responsive, and thorough.
I highly recommend Cal-Tech Plumbing for any of your plumbing needs.

I trust him and know that he will always steer me in the right direction and take care of everything I need him to! I definitely recommend working with Travis!

Cal-tech plumbing did such a great job completely remodeling my bathroom, it's so beautiful... I can't wait to get up and shower every day! Travis was our lead contractor and he really knows what he's doing, from start to finish.

Travis was willing to work within our budget and always kept us updated with revised estimates, when products arrived, & sent photos as things were completed along the way, since we were living elsewhere. He helped us pick the correct finishes and fixtures and always keeping in mind the pros and cons with each choice we had to make, and that was such a help. They were extremely thorough about protecting the floors and all other mirrored finishes that are often times overlooked. Also, when things with our electrical were not as expected, delaying everything a few days, he was willing to keep working through that as well and provide us with a skilled and trusted electrician to fix the problem immediately. His carpentry skills were impeccable and his crew was awesome. Tavis was always extremely professional, yet personable, thorough, fair, and reliable.

All in all I would say I would feel confident about recommending him to any friends or family that wanted a beautiful remodel. We are also hopefully going to use Travis to do our kitchen next!

I recently had a gas line installed by Cal-Tech Plumbing. Travis came out and completed the free estimate beforehand, and was very thorough with measurements (even crawled into the attic on a scorching hot day!) and sent me a detailed estimate. Their pricing was about half what other less professional companies were offering and their work is all guaranteed. They were flexible with my work schedule and found a date to come out ASAP to complete the work.

Travis arrived right on time, and he and John finished the project quickly. They even found and repaired a big gas leak on my water heater valve (yikes!). They also made sure to bring everything to code by strapping down the gas lines and installing an earthquake safety shut-off on our gas meter. Travis was super patient with me, as I had a million questions to ask. He took extra time to explain to me how everything worked, and even showed me how to light the pilots on my water heater and furnace.

I would highly recommend Cal-Tech Plumbing, and will definitely be calling them if I ever have future plumbing needs. They are thorough, safety-conscious, highly professional, and affordable. You can tell that Travis takes great pride in his work and does not cut any corners. Thanks Travis!

Top notch plumbing firm with solid expertise that focuses on what is right for the customer. Travis brings a level of customer service that far exceeds any plumbing service provider I have experienced - he was very responsive, thorough and priced right for the very high level of quality he brings to every job! I highly recommend checking with Travis on major and minor plumbing projects - he will guide you through options, answer questions in detail and provide the wisdom of an industry professional who gives you the details and facts beyond product literature you need as consumer - there is a reason all of his ratings are 5 stars!

Pricing was reasonable. Kept my white carpets clean. Courteous. Professional. Responsive. Very competent and skilled. I'd recommend them to anyone.


I had 3 toilets installed by Cal-Tech plumbing in November 2012. Travis and his assistant did a great job: removing the old toilets with no mess; installed the new toilets better than how the orig. builder installed the old toilets; replaced all angle stops from the kind that you have to keep turning, to the kind that turns 1/4 turn to turn on/off. All parts provided by them were very good quality parts - the kind I'd buy as a homeowner if I did the job myself. They understand most homeowners don't want to trade a few dollars here for headaches and many more dollars down the road.

For the toilets, they installed extra wax seals in the 2nd floor bathrooms to make sure everything was tight and didn't leak below. They also anchored some anchor bolts that the original builder neglected.

They also provided complementary assessment of all internal and external plumbing fixtures, etc. Helped ID some loose drain pipes and tightened on the spot. I originally asked them to help me plan out a new water heater, either tankless, or tank, high efficiency, etc. Travis provided detailed guidance and promptly sent follow up materials, etc. He was honest to provide feedback that I didn't need a new water heater, and just needed to flush out the one I had.

If you have a gas leak in your house, do not call anyone else. Don't waste your precious time or money. Call Cal-Tech Plumbing directly. Travis and his associate took care of the gas leak which was under the concrete in my garage, from trouble shooting to city inspection, to my complete satisfaction. My old house has been remodeled over the years and therefore it is not of a standard construction. As such, unforeseen problems cropped up during repair. Travis overcame them all and did not give me a change of order - did not charge me extra for the additional labor and material. Honest, dependable, and knowledgeable, you can't go wrong with Cal-Tech.
