Leak Detection & Repair in Woodbridge, VA
A hidden leak announces itself indirectly: a stain that keeps coming back, a warm spot on the floor, a water bill that climbed and never came down.
The expensive mistake is opening walls to hunt for it. Locating the leak precisely first is what keeps a leak repair a small job instead of a renovation.
Leak detection locates water escaping inside walls, under concrete slabs, or below ground without demolishing the house to find it. Lud's Plumbing uses meter isolation, acoustic listening, and pressure testing to pinpoint leaks in Woodbridge, VA, then repairs only the section that actually failed.
Signs you need leak detection & repair
- Water bill increased with no change in household usage
- A musty smell with no visible water source
- A recurring stain on a ceiling or wall
- A warm spot on a slab floor, which suggests a hot-water slab leak
- The sound of running water when nothing is on
- Mold or peeling paint concentrated in one area
How we handle it
Step 1
Isolate the system
Meter testing separates a supply leak from a drain leak and narrows it to a zone.
Step 2
Pinpoint
Acoustic listening equipment, pressure testing, and visual inspection locate the failure before anything is opened.
Step 3
Confirm before cutting
We show you where we expect the leak and why, so the access opening is small and deliberate.
Step 4
Repair
Section repair, rerouting around a slab run, or fitting replacement, depending on what we find.
Step 5
Verify
Re-pressurize and recheck the meter to confirm the system holds.

Leak Detection & Repair FAQs
How can I tell if I have a hidden water leak?
Shut off every fixture and appliance, then check the water meter's leak indicator. Movement over fifteen minutes with nothing running means water is escaping somewhere in the system. Supporting signs include an unexplained bill increase, a musty odor, recurring stains, and a warm spot on a slab floor.
What is a slab leak?
A slab leak is a break in a water line running beneath or within the concrete foundation slab. Hot-water lines fail more often because heat accelerates corrosion and expansion. Symptoms include a warm floor spot, unexplained water use, and moisture at the edge of flooring with no visible source.
Do you have to break the floor to fix a slab leak?
Not always. When a single line has failed, rerouting it overhead or through walls is often less invasive and less expensive than opening the slab. When multiple failures exist in the same line, repiping that circuit is usually the better long-term answer. We present both options with pricing.
How much water does a small leak waste?
A leak dripping once per second wastes over 3,000 gallons a year, and a pinhole in a pressurized supply line wastes far more because it never stops. Beyond the bill, continuous moisture in a wall cavity causes mold growth and structural damage that costs more than the plumbing repair.
Will insurance cover a hidden leak?
Sudden failures are commonly covered while gradual, long-term seepage often is not, and detection costs are sometimes covered separately from the repair. We document the failure with photographs and provide a written scope so you can submit a complete claim, but coverage is determined by your carrier.
