Reviews often highlight prompt responses, including late-night and same-day help, and technicians who arrive on time and work efficiently. Many customers mention straightforward, transparent pricing without pressure to upsell. Several note knowledgeable explanations and thoughtful solutions for gas lines, water heaters, and leak repairs. A smaller number report mixed experiences with phone communication and tone during estimate discussions.

I spoke to John over the phone. He was able to give me a great deal for repairing a leaky exterior main water pipe and valve. Nathaniel came out for the same-day repair. He's very professional and courteous.

B Mon on Mercy Plumbing

I called to request a quote for a water heater installation and was told that someone would need to come out to assess the current setup in order to provide an accurate estimate, which I completely understand. However, during the call, the representative stated that he was “losing $100” just by being on the phone with me. That comment was off-putting and unprofessional, and it immediately changed my impression of the company.
As a customer, I’m calling in hopes of receiving helpful guidance and good service—not to be made to feel like a burden. Rather than continuing the conversation, I let him know I would not be moving forward with their services and ended the call. Seems like they have enough business by his attitude.

John is very knowledgeable. More important, he is honest and a straight shooter. He will tell you straight if something is not right and help you understand why. I like it. We had to reroute a gas line to the outdoor kitchen. I had another contractor come in to give me an estimate. But what John proposed was brilliant. Julian and his coworker did most of the work. It was thorough. Their price was reasonable and affordable. It took them over a day to finish the entire work. I will use them in the future. I strongly recommend them.

Maureen Payton on Mercy Plumbing

Mercy Plumbing was amazing. John and Julian came out to look at my water heater and gave me a fair and transparent price right from the start. No upselling, no pressure, and no unnecessary add ons. They were honest, trustworthy, and truly focused on what I needed. They even flushed the lines in my attic for free, which was such a thoughtful surprise. I’m very grateful for their professionalism and how smoothly everything went. Highly recommend Mercy Plumbing.

Last night i had a gas leakage in my dryer gas valve. It seems when LG technician was installing the new dryer they cracked the valve.
Anyhow i contacted Mercy Plumbing late night, they responded immediately.
Nathaniel showed up 10min prior and started to work on it. He checked the whole house if they were any leakage and he mentioned that it will take around 60~90min but actually finished in 45min. He is also very knowledgeable in his work, super nice and explained the current situation.

Very trustworthy company. Thank you Nathaniel.
