The lights in my house started flickering so I called Liberty Electric power Company. They came out and checked the lines from the telephone pole to my house and they said I had an internal problem with my current electrical box which was only rated at 50 amps and it had been installed about 60 years ago. So they immediately turned off my power and would not turn it back on until I had it replaced. So I called Janusz Electric and spoke with Mitch. He was great he came out to my house within the hour, we made a deal and he started immediately with getting me some temporary power until they could come back the next morning to replace my panel and upgrade to a 200 amp. He had three guys there and they worked all day until they got the panel fixed and then he got the inspector out and got it approved so I was up and running . Everything came out great looks perfect and I'm very happy with my new service. The pricing was fair and they were very professional. THANKS MitchPosted on Google![]()

I had a wonderful experience with Janusz electrical. I had reached out on a Thursday or Friday and was able to get an appointment scheduled for the following Tuesday. It wasn't an emergency of any kind but we couldn't get some lights on our outdoor posts working. Mitch was able to determine it was just a bad switch on the outlet (I was thinking it was something significantly worse), was able to swap it out quickly and have us back up and running in no time. He was extremely professional, kind and the pricing was very fair. I would highly recommend Janusz Electric.Posted on Google![]()

Janusz did great work on a handful of move-in items I needed. Owen and Gabe showed up promptly and got right to work, coordinating tasks so they could work smoothly and efficiently. As they went they were communicative and open to questions and input I had about exactly how I wanted certain things done. The price was reasonable and fair and matched their initial estimate very closely. Highly recommended.Posted on Google![]()

Complete Home Rewiring Services for Windham, NH Homeowners
Many homes in Windham — especially older properties built before modern code updates — still run on wiring that predates today’s electrical demands. If you’re noticing flickering lights, tripped breakers, warm outlets, or you’re planning a renovation, home rewiring in Windham, NH may be overdue.
Janusz Electric, your local certified electrician, provides complete home rewiring for Windham homeowners, upgrading outdated systems to safely support modern appliances, EV chargers, smart home technology, and everyday power use — all completed to New Hampshire code.

Signs Your Windham, NH Home May Need Rewiring
Older homes throughout Windham often carry hidden electrical risks that aren’t obvious until something goes wrong. Common warning signs include:

Knob and tube wiring
Found in many older Windham homes, this outdated method has no grounding or insulation protection and is considered a serious fire hazard by today’s standards.

Aluminum wiring
Common in homes built in the 1960s and ’70s, aluminum wiring is prone to overheating and loose connections over time.

Undersized panels and outdated circuits
If you’re relying on power strips or extension cords to keep up with daily use, your panel may not be handling modern load. Our service and electric panel upgrades can pair with a rewire to solve this permanently.

Lack of grounding
Proper grounding is required for safely running electronics and protecting your home from power surges. Many Windham homeowners pair a rewire with whole-house surge protection for extra peace of mind.

Frequent breaker trips or flickering lights
Often the first visible symptom of a wiring system under strain. If breakers are tripping regularly, it may point to a deeper issue — see our circuit breaker repair services in Windham.
As your certified electrician near me, we inspect your current system, walk you through exactly what needs updating, and install grounded outlets and code-compliant wiring throughout your Windham home.

Planning a kitchen remodel, basement conversion, or room addition? It’s the ideal time to rewire — walls are already open, making it far more cost-effective than tackling it later.
