Hear From Our Satisfied Customers

“Gerard and Avery from O’Neill Plumbing replaced our water heater and kitchen faucet, and the whole experience was seamless. They were efficient, knowledgeable, and straightforward from start to finish. They took the time to walk me through my options and consistently recommended what made the most sense, rather than pushing unnecessary upgrades. I really appreciated their honesty and would absolutely recommend them.”
