Reliability

Fewer repeat outages

We rebuild weak connections and damaged cable so the fix holds through wet soil and Michigan freeze/thaw.

Performance

Even brightness

We diagnose voltage drop and rebalance runs so the end of the line doesn’t look dim or orange.

Serviceability

Cleaner wiring you can maintain

We reduce “mystery” issues by making splices, taps, and routing easier to find and service later.

How it works

  • 1

    Verify power & control

    We start at the transformer: load, taps, timer/photocell behavior, and obvious failures.

  • 2

    Locate the failure

    Voltage checks and run tracing point to the real cause: splice corrosion, damage, or drop.

  • 3

    Repair & rebuild

    We rebuild connections with waterproof splice discipline and restore cable integrity.

  • 4

    Test & document

    We confirm performance and note what matters for future service and upgrades.

Common repair calls we handle

Lights out or flickering

  • Loose or corroded splice
  • Failed lamp, socket, or fixture lead
  • Transformer overload, bad tap, or failing control

Dim at the end (voltage drop)

  • Wire gauge too small for run length
  • Too many fixtures on one run
  • Runs need rebalancing (T/hub method)

Wiring damage (critter / shovel / aeration)

We locate damaged cable, replace sections, and rebuild splices with moisture protection. If your system is older, we can also map the runs so future repairs are faster.

Pro tip: Many “mystery” lighting failures are a single corroded splice or nicked cable that only fails when soil is wet.

What affects price

  • Fixture count + layout: number of connection points and distance from the transformer.
  • Access: mulch beds vs. dense roots/hedges vs. hardscape edges.
  • Root cause: a single splice is quick; voltage drop rebalancing is more involved.
  • Controls: timer/photocell issues can be a simple swap or a broader control upgrade.

If a repair turns into a modernization opportunity, we’ll confirm scope before proceeding.
