Troubleshooting and Repair in Southern NH and the Merrimack Valley

Find the real problem, fix it, and hear it explained in plain language.

What you get

Diagnosis before repair

A breaker that keeps tripping, a warm outlet, or lights that flicker is your electrical system telling you something. We diagnose the actual cause, repair it, and tell you what we found in plain language, often the same day when it is urgent.

A lot of electrical repairs get quoted before anyone knows the real cause, which is how homeowners end up paying to replace parts that were never the problem. We do the opposite. We trace the actual fault first, show you what is going on, and repair the thing that is actually wrong, so the fix holds.

  1. Trace the real cause

    We test and trace the circuit to find what is actually happening, rather than guessing from the symptom.

  2. Repair it right

    We fix the real fault, whether that is a bad connection, an overloaded circuit, or a failing device, and confirm the repair holds under load.

  3. Explain what we found

    We tell you in plain language what was wrong and what we did, so you understand your own home and know it is genuinely handled.

Why does my breaker keep tripping?

A breaker trips to protect the circuit, so a repeat trip means something real, an overloaded circuit, a short, or a failing breaker or device. We trace the actual cause instead of just resetting it, then repair the thing that is wrong.

Can you come out the same day for an urgent problem?

Often, yes. When something feels unsafe, like a warm outlet or a burning smell, we make room to get to it quickly, often the same day. If you smell burning or see sparks, shut the circuit off and call right away.

Is a warm outlet or switch dangerous?

A warm outlet or switch is worth taking seriously, since it can point to a loose connection or an overloaded circuit. Stop using it and have it looked at. We will find the cause and correct it before it becomes a bigger problem.
