"Ken was great throughout the whole process of installing a bathroom exhaust fan. I hired him because he was very pleasant and professional on the phone, and he understood what I needed done. He worked with the schedule and short time I needed a bathroom fan installed because I had a state inspection coming up. He would answer the phone when I needed to ask him a queation, or he would call back when I left a message. It turned out the wiring from the old fan was not to code, so he figured out a way to rewire the bathroom fan without breaking open the walls. This was important to me because it was a rental unit, and I did not know what to expect. It was a great experience working with Ken, and I would recommend him for any electrical work!"

"Second time using B-Tec electric and I think now they are my go to electrician. I used them previously to upgrade my panel to 200 Amp and this time to hook up my new electric water heater. Both tasks were completed perfectly and fairly priced. I highly recommend B-Tec electric!"

"Scott is very experienced and he knew what to do with an electrical problem that I had. Opposed to other electricians, Scott knew exactly what was wrong. He did a good job and I am especially impressed with his honesty. Scott didn't use scare tactics or try to talk me into other unneeded electrical work."

"Mark and his crew installed the wiring for our pool pump along with a pool timer and added two spare circuits that we could use later. The work for the pool pump wiring was extensive since he also performed the excavation for the wiring to go underground as required by code. My husband did electrical engineering work during his career and is very knowledgeable in that area. He said Mark did excellent work and is very knowledgeable. His total cost for the project was very reasonable. We highly recommend him and would not hesitate to use him again."

"We had an excellent experience with this electrician at our 120,000 sq ft office building. He came out to perform repairs and upgrades on our electrical systems and delivered truly professional, high‑quality workmanship from start to finish. His knowledge, attention to detail, and clear communication made the entire process smooth and efficient. It’s not easy finding someone who can handle large‑scale commercial electrical work with this level of skill and reliability. He showed up on time, worked safely, and made sure everything was done correctly the first time. I highly recommend him for any commercial or residential electrical needs. Outstanding service and professionalism"

"We purchased the home a month before all of our electrical issues started. Come to find out that water was following the main wire into the panel, and moisture was building behind the breakers. We found the problem when a circuit became overloaded, and the breaker didn't trip, causing the wire to overheat and almost cause a serious fire inside the wall void and drop ceiling. We started calling all the local services, and that's when we found Alex and the crew of Princeton Electrical Makeover (PEM). Even during the great pandemic (COVID-19) of 2020, PEM was responsive, professional, reasonable, and safe when coming into our home. Alex, the owner of PEM, took our call and immediately made us feel at ease. He asked us the right questions to start diagnosing the issues and even agreed to come out and look at it himself (now that's a great owner/operator). When Alex arrived, the same day we called, he wore a mask, gloves, and even shoe covers to keep the home clean and germ-free. When he realized the severity of the situation and our need for immediate service, he agreed to do the work immediately and called in some backup. Before we knew it, the house was back and running in one day. He and his crew found multiple burnt wires and a circuit that wasn't operating as intended. My family and I appreciated the great work that done so much that we invited PEM in to do some upgrades and installation a week later. Great prices, great service, great people make for an excellent experience. THANK YOU Princeton Electrical Makeover for being caring, honest, and reliable!!!"

"If you're looking for an honest and knowledgeable electrician, R.A.P. Electric Company is the real deal. When my master bathroom outlets suddenly lost power, I spent hours checking breakers, outlets, and GFCIs without finding the problem. After contacting R.A.P. through Angi, I expected a service call and a bill. Instead, the electrician took the time to ask a few questions and patiently guided me through troubleshooting over the phone. He helped me locate a forgotten GFCI outlet in my basement that had tripped and was causing the problem. Once I reset it, everything worked perfectly. Many electricians could have charged me for a house call to perform a 30-second fix. Instead, R.A.P. chose honesty and customer service over making a quick dollar. That level of integrity is rare these days. I will definitely use R.A.P. Electric Company for any future electrical work and highly recommend them."

FAQs for electrical wiring or panel upgrade projects in Mendham, NJ

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
