    I felt every detail was taken care of when they went out the door.
    “Matt and Sean came to do my fall furnace check this afternoon and I want to say I was very pleased. They checked the airflow that I never had done before, cleaned the drain that was covered with corrosion materials, and replaced the humidifier filter with a fresh one I had. I felt every detail was taken care of when they went out the door.”

    “Bill came to our home to do a full plumbing inspection. Bill was very thorough and showed attention to detail. We noted to technician that we had a concern with our shower drain. Bill was right on it! He recommended we consider using a snake on the drain. Bill adjust the price based on the fact that it was an easy job to complete. He also tested our water and reviewed the report with us. Bill was outstanding, friendly, and very accommodating!”

    We'll definitely be using Master Plumbing going forward.
    “ohn from Master Plumbing installed a new water heater for us last week. He was prompt and thoroughly explained all of our options in the quote. It was nice having the same person doing the quote and installation. He installed it the same day. We were so pleased, we had him return to fix some previous issues with water temperature and pressure. He fixed it in no time at all and was cognizant to keep the price as reasonable as possible.”
    Chad G.
    Would definitely recommend him and Master Plumbing.
