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!

1st Class Plumbing & Drains did an amazing job replacing our water heater in Mountain House, CA. Our old unit died out of nowhere and they were able to get us scheduled quickly. Carlos showed up on time, walked me through my options, and gave a clear upfront price before starting anything. No weird add-ons, no pressure just honest explanations so we could choose what made sense for our home and budget.The install itself was super professional. They protected the work area, handled all the hauling away of the old water heater, and made sure everything was up to code. You can tell they actually care about doing things the right way, not just the fast way.Before leaving, Carlos tested everything, checked for leaks, and took the time to show us how to use and maintain the new water heater so it lasts. The area was cleaner when he left than when he arrived.If you need a water heater repair or replacement in Mountain House, I 100% recommend 1st Class Plumbing & Drains. Fast response, respectful, super knowledgeable, and genuinely trustworthy.
1st Class Plumbing and Drains's reply
Thank you so much for taking the time to leave this review and for trusting us with your water heater replacement in Mountain House 🙌 Being without hot water is stressful, so I’m really glad Carlos was able to get you taken care of quickly, walk you through the options, and keep everything upfront and pressure-free. We care a lot about doing clean, code-compliant installs and leaving the space better than we found it, so it means a lot that you noticed those details. If you ever have any questions about your new water heater or need help with anything else plumbing-related, we’re always just a call or text away. Thank you again for the 5 stars and the recommendation – it truly helps our small, family-owned business. 💛

Our water heater picked the worst possible time to die. I messaged 1st Class Plumbing & Drains and they got us on the calendar fast. They were friendly, explained what they were doing in a way that I understood, and didnt try to upsell me into something crazy. The water heater install looks super clean, they verified everything worked before leaving, and the area wasnt left looking like a construction zone. Well be using them again.
