After 25+ years serving homeowners across Coral Springs, I’ve seen it all when it comes to hidden water leaks. The worst part? Most of these costly disasters could’ve been prevented if homeowners knew what to look for early on.
Hidden leaks are sneaky. They’ll quietly destroy your home and drain your bank account while staying completely out of sight. The EPA reports that household leaks waste nearly 10,000 gallons per year on average, and some homes waste over 90 gallons daily without anyone noticing.
But here’s the good news: once you know these 7 warning signs, you’ll be able to catch leaks before they turn into major headaches. Let me share what I’ve learned from decades of emergency calls throughout Coral Springs and South Florida.
This is the #1 red flag I tell every Coral Springs homeowner to watch for. If your water usage spikes 25% or more compared to the same month last year, and nothing in your routine has changed, you’ve likely got a hidden leak somewhere.
I’ve seen families discover leaks wasting 200+ gallons daily just from monitoring their bills. A cracked underground pipe or a toilet that’s secretly running can cost you hundreds extra each month.
Quick tip: Keep your last 12 months of water bills handy. Compare month-to-month, not just the total cost (rates can change), but the actual gallons used.

Walk through your house at night when it’s quiet. Do you hear water moving through pipes when all faucets and appliances are off? That’s not normal.
Before calling a plumber in Coral Springs FL though, do this quick check:
If the meter keeps spinning with everything off, you’ve confirmed a leak in your system.
This one’s usually impossible to ignore, but I’m amazed how many homeowners try to “wait and see” if it goes away. It won’t.
Unexplained moisture anywhere in your home means water is escaping from somewhere it shouldn’t be. In Coral Springs’ humid climate, this creates the perfect breeding ground for mold within 24-48 hours.
Common spots to check:
Don’t assume it’s just condensation from our Florida humidity. Trust your instincts – if it looks wrong, it probably is.
That persistent musty smell isn’t just “old house character.” It’s often the first sign of hidden moisture from a slow leak that’s creating mold and mildew behind your walls.
I’ve found major leaks in Coral Springs homes just by following my nose. The smell typically gets stronger near the leak source, so pay attention to where it’s most noticeable.
Pro tip: Check inside cabinets under sinks, behind toilets, and around your water heater. These areas often develop that telltale musty odor before you see any visible water damage.

When water is escaping through a hidden leak, there’s less pressure available for your faucets and showers. If you notice:
You could have a leak in the supply line to that area. This is especially common in older Coral Springs neighborhoods where underground pipes may be deteriorating.
Here in South Florida, we’re used to some settling and minor cracks in our homes. But new cracks that appear suddenly, especially if they coincide with any of the other warning signs, could indicate a slab leak.
Slab leaks happen when pipes under your concrete foundation start leaking. The escaping water can undermine your foundation, causing:
These types of leaks require immediate professional attention because they can compromise your home’s structural integrity.
Water damage loves to show up in the most visible (and expensive to fix) places. Keep an eye out for:
These signs mean water has been present long enough to cause damage. The longer you wait, the more extensive (and expensive) the repairs become.

Don’t panic, but don’t wait either. Here’s your action plan:
Immediately:
Within 24 hours:
