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 / 1st Plumbing helped us replacing our water heater, Timesense / Knowledge / Work was flawless.When he installed new water heater and left, we felt gas smell and called Carlos for advise. He came back immediately and addressed the issue.Also when we asked about permits and inspection he explained everything patiently. Carlos was very knowledgable professional, Definitely support or recommend doing business with them.
