Reviews
What customers say
Customers describe the plumbers as professional and knowledgeable, and one customer valued John’s straightforward explanations. A caller seeking a water-heater installation quote said a representative made a comment they found off-putting and unprofessional, so they ended the call without moving forward.

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.

Frequently Asked Questions
What does Mercy Plumbing’s annual membership inspection cover?
It includes an annual plumbing inspection with aerator cleaning, drain and fixture shutoff-valve checks, a water-heater drain, and a camera inspection of the main sewer line if a cleanout is accessible.
How long can a Mercy Plumbing home repipe take?
Smaller homes may take a couple of days; homes over 3,000 square feet can take up to a week. Hard-to-access pipes or a more complex plumbing system can extend the job.
