Whether it’s a slow-draining shower or a kitchen sink that’s completely backed up, Radiant Plumbing & Air Conditioning is here with fast, effective drain cleaning for San Antonio homes. We’ve cleared thousands of clogs across the Alamo City, from vintage pipes in older neighborhoods to stubborn buildup in modern kitchens. Our licensed plumbers come prepared with professional tools—not store-bought chemicals—and the experience to diagnose the real cause of the clog.
We’ve worked in every type of San Antonio home, from historic properties with aging lines to modern builds with complex plumbing systems. And if a clog turns out to be part of a larger sewer line issue, we have the tools and training to handle that too.
No matter the cause, we’ll explain what’s going on, provide clear pricing, and treat your home with the respect it deserves. When you call Radiant, your drains—and your peace of mind—are in expert hands.
Clogs are more than an inconvenience—they’re often a warning sign. With the Radiant Care Club, San Antonio homeowners get ahead of drain issues before they turn into messy, stressful backups. As a member, you’ll receive an annual plumbing inspection that includes checks on sinks, tubs, floor drains, and more. Our licensed techs spot early signs of buildup, root intrusion, and poor flow—then help you take action before it gets worse.
Plus, if a clog ever catches you off guard, you’ll get priority scheduling, 10% off your service, and no dispatch fee. Whether you live in an older home with aging lines or a new build still settling, the Care Club gives your plumbing the routine attention it needs to stay clear and problem-free.
Join the Radiant Care Club and flush your drain worries for good.
When your drain backs up, you don’t want guesswork—you want results. At Radiant Plumbing & Air Conditioning, every drain cleaning service is backed by our Home Comfort Guarantee, so you know the job will be done right. That means transparent pricing before we start, licensed plumbers who respect your home, and lasting results you can trust.
We use proven methods—not quick fixes—to clear clogs and get your drains flowing again. And if you experience a backup related to our work? We’ll come back at no charge to make it right. That’s our promise. If we can’t meet your expectations, we’ll offer a 10% inconvenience refund—up to $1,000.
We take your time and trust seriously. With Radiant, you’re not just getting clear drains—you’re getting confidence that we stand behind every repair.
