Plumbing problems don’t wait for business hours—and neither do we. At Radiant Plumbing & Air Conditioning, our licensed emergency plumbers are on call 24/7 across San Antonio. Whether it’s a burst pipe at midnight, a sewer backup before sunrise, or an overflowing toilet during your weekend barbecue, we show up fast and prepared.
We’ve seen it all in San Antonio homes—from older plumbing systems in historic neighborhoods to the high-pressure issues common in newer developments. Our team diagnoses quickly, works cleanly, and gets your home back to normal with as little disruption as possible. No guesswork, no delays—just real solutions when you need them most.
Most plumbing emergencies don’t happen out of nowhere—they build up over time. That’s why Radiant’s Care Club is one of the smartest ways San Antonio homeowners can protect their homes. As a member, you’ll receive a full annual plumbing inspection from a licensed Radiant technician who knows what to look for. We catch hidden leaks, corroded lines, and failing fixtures before they turn into late-night disasters.
And if something does go wrong? Care Club members get priority service and skip the dispatch fee—because in an emergency, every minute matters. You’ll also get 10% off repairs, helping you save money when things are most stressful.
Whether it’s a slow drain that’s about to clog or a water heater on its last leg, the Care Club helps stop emergencies before they start—and gives you trusted support when they do.
When plumbing emergencies strike, you need more than fast service—you need confidence that the job will be done right. That’s why every emergency call to Radiant is backed by our Home Comfort Guarantee. We give you clear, upfront pricing before work begins—no guesswork, no games. Our technicians are licensed, background-checked, and trained to handle urgent issues with precision and care.

Plumbing emergencies don’t wait; neither does Radiant. When a pipe bursts, a sewer backs up, or a water heater lets go, Radiant moves fast with clear communication, upfront pricing, and clean, code-correct repairs. Our licensed plumbers know local San Antonio homes—from historic cottages to newer slabs—and we’re ready to support light commercial spaces along the River Walk, Pearl, and Brooks, too.
San Antonio’s environment creates its own brand of “urgent.” Sudden winter blasts can freeze hose bibbs and attic lines, leading to burst pipes and slab leaks once the thaw hits. Spring downpours around Leon and Salado Creeks push stormwater hard; floor drains and cleanouts get overwhelmed, so we come prepared for sewer backups and backwater valve issues. Year-round hard water from the Edwards Aquifer accelerates scale inside tank and tankless heaters, causing relief valves to lift, burners to trip, and hot water to run cold when you need it most. We arrive with pro-grade leak detection, isolation valves, and the parts to stabilize the situation quickly and then repair the root cause.
We’re ready 24/7 for more than just plumbing. See some related San Antonio service offerings:
From shutting off the right valve and stopping active leaks to restoring hot water and clearing critical blockages, Radiant stabilizes the emergency first—then provides options that fit your home, timeline, and budget. Residential or light commercial, when every minute matters, trust the team that protects your property and peace of mind. We Answer the Call.
