Hidden Leaks: How to Spot Them Before They Cause Major Damage

Not every plumbing issue makes itself obvious.

In fact, some of the most expensive damage we see around Newnan and across Coweta County starts with a leak you can’t see.

Hidden leaks can quietly cause:

• Water damage behind walls
• Mold growth
• Structural issues
• Higher water bills

The good news? There are usually signs – if you know what to look for.

Common Signs of a Hidden Leak

 

1. Your Water Bill Suddenly Jumps

If your usage hasn’t changed but your bill has… something’s off.

A hidden leak can run constantly in the background, slowly adding up over time.

2. Musty Smells You Can’t Explain

That damp, musty smell?
It’s often the first sign of moisture sitting where it shouldn’t be – like behind walls, under flooring, or in a crawl space.

3. Stains or Discoloration on Walls & Ceilings

Keep an eye out for:

• Yellow or brown spots
• Bubbling paint
• Warped drywall

These are clear indicators that water is getting where it shouldn’t.

4. Flooring That Feels “Off”

If your floors:

• Feel soft or spongy
• Start to warp or buckle
• Have unexplained damp spots

…it could be a leak underneath.

5. The Sound of Running Water (When Nothing’s On)

This one gets overlooked a lot.

If you hear water running or dripping when everything is turned off, there’s a good chance water is escaping somewhere in your system.

6. Lower Water Pressure

A hidden leak can reduce the pressure throughout your home – especially if it’s in a main line.

Simple Ways to Check for a Leak

 

✔ Check Your Water Meter

• Turn off all water in your home
• Watch your meter
• If it’s still moving → you likely have a leak

✔ Monitor Your Usage

Compare your current bill to past months. Even small changes can point to a slow leak.

✔ Inspect Common Problem Areas

Take a quick look under:

• Sinks
• Around toilets
• Behind appliances

You might catch something early before it spreads.
