South Corridor · Clayton · Henry · Fayette
One call.
Unit back online.
Mercer Plumbing is an owner-led plumbing contractor built for south-corridor property managers who are tired of chasing vendors. Flat per-unit pricing, a 20-minute callback and 60-minute dispatch, one invoice, and one person who answers the phone at 2am.
What we do
Plumbing service built around uptime, not tickets
A vacant unit is lost rent and a flooded unit is a claim. Mercer Plumbing is organized around getting the unit back in service and giving you a paper trail you can hand to ownership.
Multifamily & apartments
Per-unit flat pricing, turn work, unit-by-unit documentation, and a standing response window written into the agreement.
Hotels & motels
Rooms out of service cost you every night. Scheduled preventive work plus after-hours emergency coverage that does not wake a guest floor.
Senior living
Background-checked techs, quiet work, resident-sensitive scheduling, and compliance documentation for surveys.
Emergency plumbing
Burst lines, active leaks, sewage backups, no hot water. 24/7 dispatch with a 20-minute callback and 60-minute dispatch.
Backflow testing & certification
Georgia requires annual testing on most backflow prevention assemblies. We test, certify and file, and we track your due dates so you do not get a notice.
Homeowners
Water heaters, drains, sewer lines, repipes and repairs, quoted flat-rate up front before any work starts.
Why Mercer
The company is new. Nobody in it is.
Mercer Plumbing launched in 2026. We are not going to pretend otherwise, and we are not going to show you a wall of reviews we have not earned yet. What we will show you is who is doing the work.
You deal with the owner
Not a call center, not a rotating account rep. The person who signs your agreement is the person who picks up when something goes wrong.
Licensed and supervised
Every job is performed by or under the supervision of a licensed Georgia master plumber. License number is published in our footer, on every proposal, and on every invoice.
Built by a builder
Mercer is led by a third-generation Georgia builder who has run a licensed design-build general contracting firm since 2007. We understand your building because we have built buildings.
Coverage
Where we work
Mercer Plumbing works Atlanta's south corridor from a base in Jonesboro, Georgia — Clayton, Henry and Fayette counties, and the apartment corridors running up and down I-75 and I-85. That focus is deliberate: we would rather hold a 60-minute dispatch window in three counties than miss it across twelve.
