Common Underground Electrical Fault Locating Issues We Repair

We've traced every version of a buried cable fault back to its exact location. Here are the calls our clients make most often.

💡

Landscape Lighting Circuit Suddenly Stopped Working

A dead landscape lighting run often means a buried connection or cable section has failed underground, usually from moisture intrusion or ground movement. Guessing at the location and digging blindly wastes time and damages landscaping unnecessarily. We locate the exact fault before any digging begins.

🏚️

Underground Cable to a Detached Structure Lost Power

A garage, shed, or pool house that suddenly loses power often points to a fault in the buried feeder cable rather than an issue at the structure itself. Excavating the entire run to find the problem is far more disruptive than necessary. We pinpoint the fault to within a few feet before excavation.

❓

No Visible Damage but Circuit Won't Hold Power

A circuit that trips or loses power with no visible sign above ground usually means the fault is buried and invisible from the surface. Digging test holes at random rarely finds the actual problem efficiently. We use signal-based detection to find the fault without guesswork.

🚧

Worried About Digging Up a New Driveway or Patio

Homeowners understandably want to avoid tearing up a recently finished driveway or patio to find a buried cable fault. Fault locating equipment finds the exact position first so excavation stays targeted. We confirm the fault location precisely before any surface is disturbed.

🌱

Cable Fault Suspected After Recent Digging or Landscaping

Recent digging, tree planting, or landscaping work near a buried cable run is a common cause of accidental physical damage to the insulation. The resulting fault may not show symptoms until weeks later. We trace the cable and locate the exact point of damage.

🔁

Repeated Circuit Failures From the Same Buried Run

A cable that has failed more than once often has insulation breaking down along a longer section rather than a single isolated point. Repeatedly patching the same run without a full assessment tends to fail again. We evaluate whether the fault is isolated or part of a wider issue.

🔧

Old Direct-Burial Cable With No Conduit Protection

Older cable buried directly in soil without conduit protection is more exposed to moisture, soil chemistry, and physical stress than modern protected runs. This makes fault development more likely as the cable ages. We locate the fault and assess whether the run needs upgrading.

🌳

Fault Suspected Under a Mature Tree's Root System

Root growth around a buried cable can gradually compress or damage the insulation over years, eventually creating a fault. Excavating through an established root system without knowing the exact spot risks unnecessary tree damage. We locate the precise fault point to minimize root disturbance.

🛠️

Uncertain Whether the Fault Is in the Cable or the Panel

A circuit failure can sometimes originate at the panel connection rather than the buried cable itself, and it's not always obvious which one is at fault. Assuming the wrong source leads to unnecessary excavation. We test both ends of the circuit to confirm exactly where the problem is.

What Our Customers Say

Ingrid P.

Only two small holes in the yard

I was dreading a trench across the whole side yard for our dead landscape lighting circuit. Electrical Services Ontario used their detection equipment and found the fault within about a foot. Barely any digging needed.

Malcolm F.

Explained the technology clearly

I had no idea they could send a signal down the cable to find a break without digging first. The technician explained the process while he worked and it genuinely felt like watching real expertise in action.

Cassandra H.

Accurate but took longer due to clay soil

Our soil is heavy clay and it slowed the reading down a bit more than the Electrical Services Ontario technician initially expected. He was upfront about the extra time and the location he found was exactly right once we dug.

Theo R.

Fixed same day once located

Assumed this would be a two-visit job, locate one day and repair another. Electrical Services Ontario had the fault pinpointed and repaired within the same afternoon since they had the materials on the truck.

Dahlia N.

Saved our new patio from being torn up

The routing path for the buried cable ran right under our newly poured patio. They found the fault a few feet outside the patio edge instead, which meant we didn't have to worry about the concrete at all.

Gareth B.

Precise and professional from start to finish

Every step was explained before it happened, from the initial signal test to the final dig location. The precision of the equipment they used was honestly impressive to watch, and the repair has held up perfectly.

How It Works

Your Electrical Work Done in 4 Simple Steps

Licensed electrician working on a residential service panel

Call or Request a Quote

Tell us what is happening — no power, a breaker that will not reset, or a planned upgrade. We talk it through and book a time that works for you, including same-day for urgent calls.

On-Site Assessment

A licensed electrician looks at the actual panel, circuit, and load rather than quoting over the phone, then gives you a firm written price with the scope set out line by line.

Licensed Installation or Repair

The electrician who quoted the job does the work. Drop sheets go down, permits are filed where the work calls for it, and you get an update before anything changes from the plan.

Tested, Inspected, Guaranteed

Every circuit is tested before we close the panel, the inspection is booked and the certificate handed over, and our labour is warrantied for two years.

Licensed, Insured, and Local

Electrical Work Done to Code the First Time

Panel upgrades, rewiring, EV chargers, generators, and emergency repairs, all handled by licensed electricians who find the real fault and leave the work inspected.
