We find the break before we dig.
Dog fence wire-break repair and location.
A single break anywhere in the loop takes down the entire boundary, and the wire isn’t going to tell you where it is. We locate breaks in buried dog-fence wire with specialized signal equipment, open one small section of ground, and splice it waterproof. Any brand, any installer, across Richmond and Central Virginia.
The loop only works when it’s a loop. A break anywhere silences the whole boundary.
How breaks happen
What actually cuts a boundary wire.
Boundary wire lives a few inches underground, which puts it in the path of everything else that happens to a yard. The usual suspects:
Landscaping and digging
Edging beds, planting shrubs, installing irrigation, building a patio: anything with a shovel or trencher can nick the loop. If the boundary died the same week a project happened, that project is suspect number one.
Lawn aeration
Core aerators pull plugs from exactly the depth boundary wire is buried at. Aeration season is wire-break season; a break can also start as a nick that fails weeks later, so the timing isn't always obvious.
Frost and ground movement
Central Virginia's freeze-thaw cycles shift soil and flex the wire season after season. A wire under tension at a root, rock, or splice point can fatigue and part, which often shows up as a break in late winter or early spring.
Age and old splices
Insulation gets brittle, corrosion creeps into nicks, and old twist-cap or taped splices, the classic DIY shortcut, eventually let moisture in. Older systems usually have one weak point, and that's where they give out.
Professional locating
How we locate a wire break with signal equipment.
A boundary loop can be hundreds or thousands of feet long. Digging on a hunch means trenching your own yard to find a fault the size of a fingernail. Locating equipment reads the wire instead.
- 1
Confirm it's actually the wire
First we verify the fault at the transmitter (power, connections, and loop readings) so we're not hunting a break that doesn't exist. If the wire is fine, you'll hear that instead.
- 2
Put a locating signal on the boundary wire
A transmitter designed for fault-finding drives a traceable signal into the boundary wire. It's the same principle utility locators use to find buried lines.
- 3
Walk the boundary and listen
A handheld receiver follows the signal along the buried path. Where the signal changes character, the break is close, whatever happens to be growing on top of it.
- 4
Pinpoint and open one small spot
We narrow the fault to a small area, open a hand-dug section of turf, and confirm the damaged wire visually before any repair starts.
The repair
A waterproof splice, done once and done right.
The fix itself is small and precise. We take out the damaged section, add fresh wire where it’s needed, and make the connections with waterproof splice connectors built for direct burial. Twist caps and electrical tape fail underground. Moisture finds them, corrosion follows, and the same break comes back a season later.
Before the ground closes, we retest the entire loop at the transmitter rather than only the spot we fixed, because where there was one nick there is sometimes a second. Most wire-break repairs take a single visit, locating included.
Pricing, plainly: once we’ve diagnosed the fault, you’ll have a clear price before any repair work begins. We don’t run a meter while we search, and you won’t see new line items added afterward.
Honest diagnosis
Sometimes it isn’t the wire.
A dead boundary has more than one possible cause, and we check the cheap ones first. If your problem is on this list, you won’t pay for a wire hunt you didn’t need.
Power problems
A tripped GFCI outlet, a failed adapter, or an outage can silence the system with the wire perfectly intact. It's the first thing we check, and sometimes it's the whole fix.
Transmitter faults
Surge damage, failed components, or a loose loop connection at the terminals can mimic a break. The transmitter's own indicators plus a loop test usually separate the two quickly.
Collar and battery issues
If the transmitter is happy but the dog is ignoring the line, the receiver collar is the likely story: battery, fit, contact points, or a failed receiver. We test the collar at the boundary before anyone digs anything.

Before we dig
Common wire-break repair questions.
Can you repair an existing Invisible Fence® system?
Yes. We diagnose and repair systems from Invisible Fence®, Dog Guard®, DogWatch®, Pet Stop®, PetSafe®, SportDOG® and others, regardless of who installed them. Wire breaks, transmitter faults, and collar issues are all common, fixable problems.
What happens during a power outage?
The boundary is inactive while power is out, so treat the yard like an unfenced yard until it's restored. We'll explain backup options and what to watch for when power returns.
What happens if the wire breaks?
The transmitter alerts you (typically with a beep or indicator light) and the boundary stops correcting until the break is fixed. We locate breaks with specialized equipment and splice them with waterproof connectors, which is usually a same-visit repair.
