Leak Detection & Repair in Mount Pleasant & Charleston, SC
We find hidden leaks fast and fix them before they damage your home.
Signs of a Hidden Leak
- A water bill that jumped without any change in usage
- The sound of running water when every fixture is off
- Warm spots on the floor or a constantly running water heater
- Musty smells, mold, or bubbling paint from coastal humidity plus moisture
- Stained or sagging ceilings and soft drywall
- Low water pressure across the whole house
- Pinhole leaks in older copper lines common in downtown homes
- Wet, sunken, or unusually lush spots in the yard
Our Process
- Listen to the symptoms: We start with your meter reading, bill history, and the signs you have noticed to narrow down where the leak likely is.
- Non-invasive detection: Using acoustic listening devices, moisture meters, and thermal imaging, we locate the leak without tearing open walls or floors.
- Confirm the source: We isolate the exact pipe or fitting so the repair is targeted and we open only what truly needs opening.
- Make the repair: We fix the leak with proper, code-compliant materials, whether it is a supply line, slab leak, or corroded joint.
- Verify and document: We re-check the meter and surrounding area to confirm the leak is fully resolved and show you the repair.
Why Charleston Homes Are Prone to Hidden Leaks
Charleston’s warm, humid climate hides leaks well, and our hard water slowly corrodes copper and galvanized lines from the inside, producing the pinhole leaks we see often in older downtown and West Ashley homes. A small drip you cannot see can rot framing, feed mold, and waste thousands of gallons before you notice it on the bill. Our leak detection is deliberately non-invasive, so we pinpoint the source before opening any wall or slab. Get in touch the moment you suspect a leak anywhere in Mount Pleasant or greater Charleston.

Frequently Asked Questions
How can you find a leak without cutting into my walls?
We use acoustic listening equipment, moisture meters, and thermal cameras to trace water behind walls, under floors, and beneath slabs. That lets us mark the exact spot so any opening we make is small and targeted instead of exploratory.
What is a slab leak and is it common in Charleston?
A slab leak is a leak in a water line that runs beneath your home’s concrete foundation. They occur here as supply lines corrode or shift with the soil. Signs include warm floor spots, unexplained high bills, and the sound of running water with everything off.
My water bill spiked but I do not see any water. What should I do?
Turn off every fixture and check your water meter; if it is still moving, you have a hidden leak. Catching it early prevents structural damage and mold in our humid climate. Call us and we will locate and repair it before it gets worse.
Do you handle leak repair in Mount Pleasant, SC?
Yes. We are based in Mount Pleasant, so leak calls in Park West, Carolina Park, the Old Village and the rest of town are usually reached the same day. We also cover Charleston, Daniel Island, the beach communities, James Island and West Ashley.
Is a hidden leak an emergency?
If water is actively running, the meter is spinning with everything off, or you see a ceiling sagging or a floor going soft, treat it as urgent and shut off the main. We offer 24/7 emergency response for active leaks. A small, slow leak is less urgent but should still be found quickly; in Charleston humidity it feeds mold fast.
What happens after you find the leak?
We show you exactly where it is, explain what caused it, and give you an upfront, flat-rate quote for the repair before any work begins. Most leaks are a targeted repair at one spot. If the pipe material is failing in several places, we will tell you honestly whether repiping makes more sense than another patch.
