"Did a $59 consult only. Turned out the cost of repairing the old heater was almost as much as a new one, so we got a new one, and handled the install ourselves. Luis B was great, knowledgeable, friendly, didn't try to upcharge just to sell a heater, which we appreciated. Gave us an honest evaluation, several options, and was right on time. I will say, though, that the company failed to call me when he was on his way... not a big deal. All in all a good experience."

"All the people sent to my home were professional, friendly and efficient. Eric, the repair tech, had to give me the bad news that my furnace was not repairable. He listened to my requirements and desires for the replacement and gave me a solution that matched at a reasonable cost. Novlin and Brandon came the next day to install the unit. They were careful of my home and floors. They installed the new furnace quickly and efficiently. They cleaned up after themselves very well. Before leaving, they showed me pictures of the work in the areas that I couldn't easily get to like the attic and roof. I'm very happy with the whole project"

"They called us quickly and got a plumber out within a few days. Super thorough - tested all pipes and water sources to diagnose the problem. They were able to perform maintenance on most bathrooms the same day and improve the water temperature in our showers. Gave helpful, non-biased advice on potential further plumbing improvements. We will likely call this company again for any and all future plumbing needs."

"Good Day Plumbing has done multiple projects for us. They have installed a tankless water heater, a water softener, and also replaced a backflow. Good Day was competitive with their quotes and worked around our schedule. All of the work was done in a clean, professional manner and they even helped us out in understanding the operation and maintenance that would be required for the water heater and softener. We would not hesitate to call them out for our next project or unexpected repair. Itâ s good to have a company like this you can trust to do the work right the first time and treat you in an honest and fair manner."
