Who We Are
Northlake Plumbing has been solving Atlanta-area plumbing problems since 1975 — which means Walter Cooper and his crew have seen every aging cast-iron drain, every slab leak hiding under a Gwinnett County crawlspace, and every water heater that chose the worst possible day to give out. Walter is a licensed master plumber who built this company from the ground up and still leads a team of journeymen and apprentices on every job. With 4.5 stars across 76 Google reviews earned over five decades, the work speaks louder than any ad ever could.

“Called Northlake after another company told me I had a slab leak and quoted me something astronomical. Walter's crew came out, found the actual source — a corroded supply line under the bathroom — and fixed it the same day for a fraction of what I was quoted. These guys are the real deal.”

“Our water heater died on a Sunday morning with a houseful of guests. I found Northlake Plumbing online and they picked up right away. New unit was installed by early afternoon. I've used them twice since for smaller stuff and they're consistently fast and straightforward about what things actually cost.”

“I bought an older home in Norcross that needed a lot of plumbing work before we moved in — new fixtures throughout, a couple of bad shutoff valves, and a drain that hadn't been properly cleaned in years. Northlake handled all of it in two visits. Walter walked me through everything they found before touching a thing, which I really appreciated.”
