Highly recommend this plumbing company! From the first call to the completed job, everything was handled professionally. They arrived on time, explained the work clearly, and provided upfront pricing with no surprises. The work was done cleanly and efficiently, and they made sure everything was tested before leaving. Honest, reliable, and knowledgeable. Exactly what you want in a plumber!

I recently had a sump pump installed by OC Plumbing & Water Heaters and had a great experience. The team was professional, on time, and very easy to work with. They explained the process clearly and made sure everything was installed properly and cleanly. The work was done efficiently, and the area was left spotless. Pricing was straightforward with no surprises. Overall, very reliable service - I’d definitely recommend them for any plumbing needs.
