Winter might seem like an unlikely time to worry about water leaks, but January is actually one of the most critical months to inspect your home for hidden water problems. Between freezing temperatures, increased indoor heating, and the stress winter places on your plumbing system, leaks can develop quickly and silently cost you hundreds of dollars in wasted water and potential damage.
At EJ Water, we’re committed to helping our community conserve water and protect their homes. That’s why we’ve put together this guide to help you spot the warning signs of hidden leaks before they become major problems.
Why January is Prime Time for Leak Detection
Cold weather puts extra strain on your plumbing system. Pipes expand and contract with temperature changes, seals can deteriorate, and increased water usage during the holidays can reveal weak points in your system. Plus, with everyone spending more time indoors, you’re more likely to notice the subtle signs of a leak.
Catching a leak early can save you from:
- Wasted water and higher utility bills
- Structural damage to your home
- Mold and mildew growth
- Costly emergency repairs
5 Warning Signs of a Hidden Water Leak
1. Your Water Bill Has Unexpectedly Increased
One of the most obvious indicators of a hidden leak is a spike in your water bill with no change in your usage habits.
What to do: Compare your current water bill to bills from the same time last year. If you notice a significant increase without a corresponding change in usage (like extra guests or lifestyle changes), it’s time to investigate.
2. You Hear Water Running When Nothing is On
Do you hear the sound of running water when all faucets are off and no appliances are in use? This phantom sound is often your plumbing system trying to tell you something is wrong.
What to do: Turn off all water sources in your home and listen carefully. Check near water heaters, under sinks, and along walls where pipes run. If you hear trickling or dripping, you likely have a leak that needs attention.
3. There are Damp Spots, Stains, or Discoloration
Water stains on ceilings, walls, or floors are telltale signs of a leak. You might notice yellowish-brown spots, bubbling paint, warped wallpaper, or soft spots in your drywall. In winter, you might also see unexplained puddles or moisture in basements or crawl spaces.
What to do: Document any stains with photos and monitor them over a few days. If they grow or change, you have an active leak. Don’t ignore even small stains, as they often indicate a larger problem behind the wall.
4. Your Water Meter Keeps Running
This simple test can definitively tell you if you have a leak somewhere in your home. Your water meter is an honest indicator of water flowing through your system.
What to do: Turn off all water-using appliances and faucets in your home. Check your water meter and write down the numbers. Wait 1-2 hours without using any water, then check the meter again. If the numbers have changed, you have a leak.
5. There’s a Musty Odor or Visible Mold
Persistent moisture from a hidden leak creates the perfect environment for mold and mildew growth. If you notice a musty smell in certain areas of your home, especially near bathrooms, kitchens, or basements, a leak could be the culprit.
What to do: Mold often grows in hidden areas like behind walls, under flooring, or in cabinets. If you detect a musty odor without an obvious source, it’s worth having a professional investigate.
Common Leak Locations to Check
Now that you know what to look for, here are the most common places leaks occur:
- Under sinks and around toilets – Check cabinet floors for warping or moisture
- Water heater connections – Look for rust, corrosion, or pooling water
- Washing machine hoses – Inspect for cracks, bulges, or loose connections
- Outdoor faucets and hoses – Freezing temperatures make these especially vulnerable
- Basement and crawl space pipes – Cold spots are prone to condensation and leaks
What To Do If You Suspect a Leak
If you’ve identified one or more of these warning signs, here’s your action plan:
For minor visible leaks: Turn off the water supply to that fixture and contact a licensed plumber and/or EJ Water.
For major leaks or emergencies: Shut off your main water valve immediately and call for professional help.
For suspected hidden leaks: Contact a plumber who specializes in leak detection and/or EJ Water. They have specialized equipment like moisture meters and thermal imaging cameras that can pinpoint leaks without damaging your walls.
Monitor your water usage: Keep an eye on your water meter and bills to catch future problems early.
Prevention is Your Best Defense
While not all leaks are preventable, regular maintenance can dramatically reduce your risk:
- Insulate exposed pipes in unheated areas
- Disconnect and drain outdoor hoses before winter
- Keep your home heated to at least 55°F, even when away
- Have your plumbing system inspected annually
- Replace old fixtures and appliances on schedule
- Know where your main water shut-off valve is located
The Bottom Line
A small leak might not seem like a big deal, but over time it can waste thousands of gallons of water, increase your utility bills, and cause serious damage to your home. This January, take 30 minutes to walk through your home and check for these warning signs.
