Matt is reliable, honest, respectful, trustworthy and charges fair prices for services rendered. It took many years, and several unethical, unreliable and untrustworthy plumbers who charged inflated prices for sub-par work. My wife and I highly recommend Hatfield Brothers.

Hatfield Brothers replaced my furnace and recently replaced my water pressure tank. They are honest, reliable, and do an excellent job.

Matt and his crew installed our new furnace after ours failed. They were great! Timely, clean, and professional. After the install Matt kept in touch to make sure everything was working well and if we had any questions. Fantastic job! Couldn’t be happier.
