Electrical Troubleshooting & Repair
Dead outlets. Flickering lights. A breaker that keeps tripping. We find what is causing the problem and explain the repair before you decide.
Family-owned since 1979Based in DracutScope and pricing explained first
Basic diagnostics start around $299 and include an eligible small outlet, GFCI or switch repair within the agreed scope.
Start with the symptom
What has stopped working?
The same symptom can have several causes. We test the affected devices and circuits so you can make a repair decision based on findings, rather than a guessed replacement.
A breaker that keeps tripping
The cause may involve a connected appliance, circuit loading, a wiring fault or the breaker. A trip alone does not mean you need a new panel.
Flickering or dimming lights
Tell us whether one fixture or multiple rooms are affected and whether it happens when another device starts. That pattern helps guide the investigation.
Partial or widespread power loss
The scope matters: one room, several areas or most of the home can require different diagnostic levels. For a full outage, check with your utility first.
Smoke, fire or immediate danger? Leave the area and call 911. An online service request is not an emergency response.
Know what the visit covers

The diagnostic fee pays for skilled testing and investigation to locate the cause. We explain the appropriate level and scope before starting.

Diagnosis and repair
A small repair can be part of the visit.
If the diagnosed issue is resolved by an eligible small device replacement within the agreed basic scope, that repair is included. You get both an explanation of the cause and the appropriate small repair.
Some symptoms trace back to a broader wiring or circuit problem. We explain what is involved and the price before doing work outside that scope.
A straightforward visit
From the first symptom to a clear next step.
Share what you have noticed. We handle the investigation, explain the findings and discuss the repair.
Tell us the pattern
Which rooms or devices are affected? When did it start? Does it happen constantly or only when something runs? No need to remove covers or touch wiring.
Understand what we find
We confirm the diagnostic scope, test the affected equipment and circuits, and explain the cause and repair options.
Approve the right work
We complete the agreed work and check the affected equipment or circuit. Parts, access and the cause determine whether a return visit is needed.

Before you book
Questions about electrical troubleshooting.
How do I know if I need electrical troubleshooting?
An existing fault, such as repeated breaker trips, a dead outlet, flickering lights or partial power loss, calls for diagnosis before choosing a repair. Tell our office what happens and when so we can arrange the appropriate visit.
Does a tripping breaker mean I need a new panel?
Not necessarily. Circuit loading, connected equipment, wiring faults and breaker issues can require different solutions. We investigate the cause and assess the existing equipment before recommending repair or replacement.
Why are my lights flickering or dimming?
The cause may involve a lamp, fixture, dimmer, connection, circuit or the supply to the home. Tell us whether one fixture or several areas are affected and whether the flicker happens when equipment starts. Diagnosis determines the next step.
Can you fix outlets that stopped working?
We can investigate a failed outlet and the circuit serving it. Replacing the receptacle alone may not address an upstream connection or another circuit problem, so testing comes first.
How long does electrical troubleshooting take?
Timing depends on the symptoms, access and the cause. An intermittent fault or concealed wiring can take longer to investigate. We explain the findings and the scope of any additional work rather than promise a fixed completion time.
How much does electrical troubleshooting cost?
Basic diagnostics start around $299 and include an eligible small repair, such as replacement of a standard outlet, GFCI or switch within the agreed scope. Advanced diagnostics are $599 for more extensive investigations, including problems affecting multiple areas. Whole-home diagnostics cover widespread issues affecting more than half the home or a full power outage; pricing is confirmed before work. Additional repairs are explained and priced separately when outside the agreed scope.
What small repairs are included in a basic diagnostic?
An eligible small repair includes replacing a standard outlet, GFCI receptacle or switch when it resolves the diagnosed problem within the agreed basic scope. Broader wiring repairs, additional faults and other work outside that scope are explained and priced before you authorize them. Parts, access and the actual cause affect whether the work can be completed during the visit.
