Hired on Thumbtack
The team arrived on time, quickly assessed my plumbing situation and offered me a lower cost option than what was initially quoted. Carlos explained everything in detail while also providing visual insight of the problem. They were quick, efficient, transparent, offered excellent pricing and respectful of the property. Went the extra mile to make sure everything (systemic) was in proper working order beyond the localized problem area. Fixed a problem in an area and did not charge me for it. Excellent work by Carlos & Anthony. Will hire this team in the future for any plumbing problems. Truly appreciate the quick, cheap and professional resolution to our problem!

Carlos and Anthony replaced the WC in the guest bathroom. We had a piece of plastic stuck in the old toilet and he gave us honest options! He was super responsive as we coordinated the arrival of the new WC and its installation. Work was clean and the price was reasonable. I will absolutely hire him again for all my plumbing needs. Thank you, Carlos and Anthony!

Carlos responded quickly and came the same day to replace a broken kitchen faucet. He explained his recommendation based on the age of faucet not just a quick fix and we feel secure following it. He's very personable, got parts fast and did an excellent job with clean up. We will call him again if needed and wholly recommend him.

Carlos responded promptly to my message and scheduled time the next day. He arrived right on time. He explained the process clearly, did a good job resolving the issue and helping us understand what happened. He left the bathroom as clean as he found it. He was very professional in every aspect. Highly recommended!

Thank you, Yash. We’re really glad we were able to help with both your sewer lateral repair and the branch line blockage at your San Ramon property. Carlos always makes sure to explain everything clearly and leave the area cleaner than he found it, so it means a lot that you noticed. We appreciate your trust in us for both jobs, and we’re here anytime you need sewer, drain, or plumbing help in the future.

Excellent all around. Carlos was responsive and accommodating. He arrived, replaced our water heater, and removed the old one – all within two hours, at a very reasonable price. Add to that: he's very friendly, and good to have around. Highly recommended – we will definitely be calling on him again.

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
I give upfront pricing before starting any work - no surprises. Pricing includes labor, materials, and cleanup. Emergency service after 6pm or weekends is +$75. I don't charge travel fees within my service area. Payment is due when the job is complete - I accept cash, credit card, Venmo, or Zelle.
What is your typical process for working with a new customer?
First, I respond to your request within 30 minutes to set up a time. When I arrive, I assess the problem, explain what needs to be done simply, and give you an exact price before starting. Once you approve, I get the work done efficiently and test everything to make sure it's working properly. Then I clean up and make sure you're satisfied before I leave.
What education and/or training do you have that relates to your work?
I'm a California licensed plumber with 36 years of hands-on experience. I've worked on everything from simple drain clogs to complex commercial installations. I stay current on California plumbing codes and requirements, and I'm fully bonded and insured.
