If you live in Austin, there’s a good chance your home sits on a concrete slab foundation. While slab construction can be efficient—and thankfully basement-free—it comes with its own set of challenges. One of the biggest? Hidden plumbing issues under the foundation, especially slab leaks.
A slab leak happens when water pipes underneath the slab crack, corrode, or burst. These leaks are hard to detect but can cause major damage and sky-high water bills. At Radiant Plumbing, we specialize in diagnosing and repairing slab leaks across the Austin area. Below are three common signs to help you spot one before it causes serious trouble.
1. Mystery Moisture or Cracked Flooring
Have random puddles appeared in your home with no obvious source? That water may be seeping up from a leaking pipe beneath your foundation. Other red flags include cracked tiles, warped flooring, or mildew near the base of your walls. If the leak involves a hot water line, you might even feel warmth in specific spots on the floor.
These signs often go hand-in-hand with hidden drain line leaks that slowly saturate your home’s foundation. Left untreated, they can weaken structural integrity and increase the risk of mold.
2. The Sound of Running Water (When Nothing’s On)
Hearing water flow when all faucets and fixtures are turned off? That could be water escaping from a damaged pipe below your home. This is one of the most common symptoms homeowners report before discovering a slab leak.
Our team uses advanced leak detection tools to track down the source—whether it’s a broken freshwater line or an issue with your main sewer line.
3. Rising Water Bills with No Explanation
Have your water bills spiked, even though your daily usage hasn’t changed? A slab leak could be the culprit. Water leaking below the foundation still registers on your meter, which means you’re paying for water that never reaches your faucets.
You can run a quick test: shut off all water in your home and check the meter. If it’s still moving, there’s likely a hidden leak—and it’s time to call in the pros.
