Columbus Master Plumbers Since 1996
JA Mechanical LLC is a family-run residential plumbing company serving Columbus and Central Ohio since 1996. For 30 years, owner and master plumber Antwan Allen has built the business on a simple promise:Integrity & Service After the Sale. We are a licensed and insured Ohio plumbing contractor (License #PL.29708), and we stand behind our workmanship 100%.
Antwan learned the trade hands-on, working residential service calls across every kind of Columbus home — from century-old German Village row houses to newer builds in the suburbs. That field experience drives how JA Mechanical operates today: diagnose the real problem, explain it in plain terms, give an upfront price, and fix it right the first time. We do not sell you services you do not need, and we do not disappear after the invoice is paid.
From a running toilet in a 30-year-old home to a same-day water heater replacement on a freezing January morning, our team treats every job like it is on our own home. When you call JA Mechanical, you reach a real local plumber who answers the phone live, day or night.

Our Story
JA Mechanical LLC started as a one-truck residential plumbing operation in Columbus, Ohio, built on the belief that homeowners deserve a plumber who shows up on time, tells the truth about what is wrong, and finishes the job cleanly. Antwan Allen named the company with his own initials because his reputation is on every job the truck rolls up to.
Over 30 years, that standard earned JA Mechanical a reputation across Columbus neighborhoods — German Village, Clintonville, the Short North, and out into the suburbs — for honest diagnostics and work that lasts. We carry thermal imaging and acoustic leak detection so we find the problem without guessing, and we stock our service vehicles to finish most repairs in a single visit.
Our motto, "Integrity & Service After the Sale," is not a slogan we hung on a wall. It is the rule Antwan runs the company by: if something we installed or repaired is not right, we come back and make it right. That is what we mean by standing behind our workmanship 100%.
