What Is Home Rewiring and Why It Matters?

Home rewiring involves replacing old or faulty electrical wiring in a house to meet current safety standards and support modern electrical demands. In many older homes across New Hampshire, original wiring systems were not designed to power today’s appliances, electronics, or smart devices.

Outdated wiring can increase the risk of electrical fires, power outages, and damage to your equipment. In some cases, it can also prevent you from getting home insurance coverage or passing a home inspection. Whether you’re concerned about safety, planning a renovation, or simply want peace of mind, home rewiring is a smart and necessary investment.

Home Rewiring for Older Homes in New Hampshire

Many homes across New Hampshire were built before modern electrical codes and safety standards existed. If your home was constructed before the 1980s and hasn’t been rewired since, there’s a good chance the electrical system may be outdated or even hazardous.

Older homes often contain:

Knob and tube wiring

This early wiring method lacks grounding and insulation protection, making it highly unsafe by today’s standards.

Aluminum wiring

Common in homes built during the 1960s and 70s, aluminum wiring is prone to overheating and loosening at connection points, which can increase the risk of fire.

Undersized panels and outdated circuits

Electrical panels from past decades weren’t built to handle the load of today’s technology. If you’re using extension cords or power strips just to keep up, your home may be due for an upgrade.

Lack of grounding

Grounding is essential for safely running electronics and protecting your home from electrical surges. Many older systems don’t include proper grounding.

We specialize in rewiring older homes with the attention and care they deserve. Our experienced team will thoroughly inspect your current system, explain what needs to be updated, and replace outdated or unsafe wiring with modern, energy-efficient, and fully code-compliant materials. We also ensure your home is equipped with the right number of grounded outlets, GFCI protection in critical areas, and an upgraded panel that can support today’s electrical demands

What to Expect During a Rewiring Project

Rewiring your home is a big decision, and knowing what to expect can make the process smoother and less stressful. At Janusz Electric, we believe in clear communication and high-quality workmanship from start to finish.

Initial consultation and inspection

We start with a full evaluation of your current wiring system. We’ll look for safety concerns, code violations, and areas that need updating. We also take time to understand your goals, whether it’s increased capacity, additional outlets, or support for smart technology.

Customized plan and estimate

Once we understand your home’s needs, we’ll provide a detailed plan and transparent quote. You’ll know exactly what we’re doing, why it’s needed, and how much it will cost.

Permits and code compliance

Our team takes care of all required permits and ensures your new wiring meets local and state electrical codes in New Hampshire.

Professional installation

We complete the rewiring with minimal disruption to your home. Our electricians work efficiently, clean up after themselves, and keep you updated throughout the process.

Final inspection and walkthrough

Once the work is complete, we test everything to ensure safety and performance. We’ll walk you through the upgrades, show you how to use any new features, and answer any questions you may have.

Rewiring doesn’t have to be overwhelming. With Janusz Electric, you get a trusted team that puts your safety, comfort, and satisfaction first.

Rewiring During Renovations and Remodels

If you’re planning a home renovation or adding new rooms, it’s the perfect time to consider upgrading your electrical wiring. During a remodel, walls are often already opened up, making it more efficient and cost-effective to install new wiring that meets your updated needs.

Janusz Electric works closely with homeowners, contractors, and designers to ensure your electrical system aligns with your renovation plans. Whether you’re reconfiguring room layouts, adding lighting, or integrating smart home technology, our electricians can rewire your space to match.

We provide rewiring services for:

Kitchen and bathroom renovations
Home office and basement conversions
Room additions and garage upgrades
Whole-home remodels and layout changes

Rewiring during construction or remodeling not only helps your project run more smoothly but also future-proofs your home for years to come. We ensure that everything is up to code, supports your desired electrical load, and is installed with precision and care.

 Trustindex verifies that the original source of the review is Google. 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 Mitch

 Trustindex verifies that the original source of the review is 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.

 Trustindex verifies that the original source of the review is 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.
