Best Electrical Contractor in Portsmouth, NH 3802 - JNJ Electric

If you suspect rodent damage, it's a serious safety risk that requires immediate attention from a licensed electrician. At JNJ Electric, we safely inspect your wiring, identify all compromised sections—often in attics, basements, and crawlspaces common in our area—and perform expert wire repair or replacement. We also recommend solutions to help prevent future infestations from causing electrical fires or outages in your Portsmouth home.

Frequent tripping is a classic sign of an overloaded panel, a common issue in older Portsmouth homes as families add more devices. It means your system is working harder than it safely can. Our electricians can diagnose the cause, which may involve repairing a faulty breaker or, more often, recommending a panel upgrade. Installing a new, higher-capacity electric panel ensures your home can handle modern electrical loads safely and prevents potential fire hazards.

Absolutely. Installing an EV charging station often requires an assessment of your existing electrical panel's capacity. Many older panels are already near their limit. We provide a comprehensive service: we evaluate your system, perform any necessary electric panel repair or installation to add capacity, and then expertly install your charging station. This ensures safe, efficient charging and prevents overloads on your home's electrical system.
