If youve ever noticed mysterious damp spots on your floor, unexplained spikes in your water bill, or the faint sound of running water when everythings offwelcome to the club. Ive been there.

Heres what I learned (and wish Id known sooner) about detecting a slab leak yourself.
What Is a Slab Leak, Anyway?
A slab leak occurs when pipes beneath your homes concrete foundation spring a leak. Since these pipes are buried, leaks arent always obvious until you start seeing water damage, hear running water, or notice higher water bills. In my case, it started with warm tile floors in July. Not exactly cozy.
5 DIY Tips to Detect a Slab Leak
1. Monitor Your Water Bill Closely
If your usage hasnt changed but your bills skyrocketing, thats a red flag. I tracked mine for two months before realizing it was way off.
2. Try the Water Meter Test
Turn off all water in your house. Check the water meter and wait an hour. If the numbers move, theres likely a hidden leakpossibly under your slab.
3. Look for Warm Spots on the Floor
This was the biggest giveaway for me. Id step into the kitchen andbaman oddly warm tile. Leaks from hot water lines often cause warm patches on concrete floors.
4. Listen for Running Water
At night when the house is quiet, I could hear faint hissing. Turns out, my pipes were whispering, Help me!
5. Check for Mold or Mildew
That musty smell? It could mean waters been sitting under your flooringgross and unhealthy. I pulled up a corner of carpet and, yep, mold city.
