When temperatures drop below freezing, your plumbing system is under pressure—literally.
Frigid weather is one of the leading causes of hidden water leaks in homes across New Jersey and other cold-climate states. Unfortunately, many of these leaks go undetected until major damage occurs.
At First Class Leak Detection, we specialize in finding leaks even during the coldest months of the year—without damaging your walls, floors, or foundation.
Here’s what you need to know.
Why Freezing Temperatures Lead to Leaks
Cold weather impacts your pipes in a few dangerous ways:
- Expansion of frozen water inside pipes can cause them to crack or burst
- Shifting soil from freeze-thaw cycles can stress underground and slab pipes
- Frozen hose bibs or sprinkler systems can leak slowly into foundations or walls
- Hidden hairline fractures often don’t reveal themselves until thawing begins
Signs of a Hidden Leak in Winter
Even if you don’t see water, you may still have a leak. Look out for:
- Sounds of running water when everything is turned off
- Unexplained drop in water pressure
- Cold spots or dampness on walls, floors, or ceilings
- Spikes in your water bill
- Frozen pipes that suddenly thaw and drip
Don’t assume a leak will stop once the pipe thaws—it may just start leaking in secret.
How We Find Winter Leaks Without Damage
Our cold-weather leak detection process uses advanced non-invasive technology, including:
- Acoustic listening devices to hear leaks beneath concrete or behind walls
- Thermal imaging cameras to detect heat loss and water movement inside walls
- Tracer gas for hard-to-find underground or slab leaks
- Moisture meters to map trapped water in insulation, flooring, and drywall
We locate the leak fast—so your plumber or repair team can fix it without guesswork or unnecessary demolition.
Cold Weather Leak Detection Checklist
If the temperature has dropped and you suspect a leak, do this:
- Turn off all faucets and appliances
- Listen carefully near bathrooms, kitchens, and basements
- Check your water meter – is the leak indicator spinning?
- Inspect outside walls and exposed pipes for frost, bulges, or dampness
- Call a professional if anything feels off—trust your instincts
