Homeowners in Douglas, GA, count on their plumbing to stay out of sight and out of mind. But when pipes under a concrete foundation develop leaks or burst, especially in colder weather, the consequences can be serious. Understanding how to spot a slab leak early is one of the most important steps you can take to prevent structural damage, expensive repairs, and avoidable headaches.
Our plumbers at Mr. Rooter Plumbing of Southeast Georgia highlight the five key warning signs of slab leaks and burst pipes below concrete, explain why they happen, and share how Douglas homeowners can protect their properties.
Why Do Slab Leaks Happen & Why Should You Be Cautious of Cold Snaps?
A slab leak is simply a water leak that develops beneath a home’s poured concrete foundation. Most commonly, these leaks involve copper pipes, which can corrode, shift, or crack over time. Colder weather increases the risk. As temperatures drop, the ground under your foundation contracts, pipes are exposed to more stress, and freezing water can cause even well-installed pipes to burst.
With the area experiencing real temperature swings between seasons, winter and early spring pose an extra risk for hidden leaks under homes and businesses.
5 Signs of a Slab Leak Under Your Foundation
1. Unexplained Spikes in Water Bills
One of the most obvious tip-offs of a slab leak is a sudden, unexpected increase in your utility bill. If your water usage hasn’t gone up but your costs have, water could be escaping somewhere you can’t see (beneath the slab). In Douglas, many homeowners see winter bills jump as colder weather triggers hidden leaks.
Regularly reviewing your monthly water bills and comparing usage is a straightforward first step in slab leak detection. A consistent upward trend, even if minor, deserves attention.
2. Damp, Wet, or Warm Spots on Your Floors
Slab leaks can reveal themselves as persistently damp or warm patches on the flooring above your foundation. If you notice spots on your carpet, tile, or laminate that are warmer—or even wet—to the touch, you could be dealing with a leaking hot water line under the slab.
Douglas’s clay-rich soils make trapped moisture more likely to linger just under the surface, drawing that warmth or dampness up into the floor. These symptoms become more noticeable in winter, when your heating system makes any leak-related hot spots stand out on cold floors.
3. Cracks in Walls, Baseboards, or the Foundation
As water escapes under a slab, it changes the consistency of the soil, causing shifting and settling.
Over time, the loss of support can lead to visible cracks forming:
- In interior walls—hairline fractures that widen or grow over time
- Along baseboards or where the floor meets the wall
- In the concrete foundation itself
You may notice new cracks becoming more pronounced after a cold snap because pipes are more susceptible to bursting in low temperatures. Not every crack means a slab leak, but new or growing fissures are always worth a professional inspection.
4. Low Water Pressure Throughout the Home
A lower flow rate in showers, faucets, or appliances can point to a problem with water escaping before it reaches its destination. When a pipe under your slab bursts or develops a leak, it steadily reduces water pressure throughout the house.
Sudden, unexplained drops in water pressure—especially after a cold night—can signal a major leak. In homes with multiple bathrooms, widespread low pressure is a red flag and should not be ignored.
5. Mold, Mildew, or Musty Odors
Persistent leaks create a moist environment prime for mold and mildew, under your floor and, eventually, inside your home. If there’s a musty odor that doesn’t fade after cleaning or seasonal mustiness appears in winter, there could be water trapped under your slab.
Wet flooring promotes mold growth, which is extremely dangerous for loved ones with allergies or respiratory issues. Douglas’ humid climate adds to this risk, making prompt investigation and remediation essential.
How Cold Weather in Douglas Adds Risk
Douglas winters may be mild compared to other regions, but localized freezes and temperature dips are enough to stress pipes under slabs. As the ground cools and shifts, pipes contract and may burst where they were already weakened by corrosion or age. When water inside these pipes freezes, it expands, causing breaks and rapid leaks once temperatures rise. Regular winter plumbing checks and insulating exposed lines can help reduce these risks.
What to Do If You Suspect a Slab Leak or Burst Pipe
If you notice any of these signs, don’t wait. A small leak can quickly spiral into major property and structural damage.
Steps to take include:
- Turn off the main water supply to prevent further flooding.
- Avoid running heat directly over wet spots to “dry them out”—this can worsen damage.
- Call a professional plumber with experience in pipe leaks for fast, accurate detection and repair.

Keep slab leaks at bay by:
- Scheduling regular plumbing inspections each year, especially before the cold season.
- Insulating exposed pipes and sealing external cracks to reduce cold air intrusion.
- Maintaining steady soil moisture around your home’s foundation to minimize shifting.
