"Ray and his crew thoroughly explained and reassured me about everything pertaining to the work they were doing for my electrical panel upgrade. Ray also took the time to talk to me and make suggestions on what types of doorbell or bathroom fan to consider buying. There were supply chain shortages during the pandemic of a part that I needed for my electrical panel upgrade. Ray made sure to keep in touch and provide regular status updates of my job. In addition, they cleaned up thoroughly afterwards and their prices were also very competitive. I will be calling Celano Electric for my future electrical needs!"

"We needed a turnkey solution two 35+ year old bathroom exhaust fans that were dying. Anjali in the main office understood and coordinated with Brad to make it happen. Brad is an excellent communicator who did beautiful work selecting and installing a replacement exhaust / heat fan and switch panel in the master bath. He saved us the expense of the powder room exhaust fan replacement by making a repair instead. Brad Brown Electrics is our new go-to business for future electrical work!"

"Glenn goes above and beyond for his customers. We hired Glenn for a number of different activities including hanging 75” TV over the mantle, installing recessed lighting and fixing the electrical panel. Glenn is knowledgeable, hardworking and always wants his customers to be happy with the end product. This combination of attributes makes for one top-notch electrician! Highly recommended"

"Bill H from Gambino Electric showed up promptly on time for the job. There were some edge ceiling tiles that needed to be removed to reach the power line and Bill did very clean work with the removal and disposal. Bill showed cross sections of the older range power line and the new line installed, describing the differences in insulation and safety features of the newer line. Bill went above and beyond by detecting the wrong cord on the new range, and replaced this with the proper range gauge power cord. Bill also helped us to correctly position and level the new range appliance. I would recommend Bill and Gambino Electric for any similar household wiring job where safety and quality of work are a priority."

"John was responsive and quick to set a meeting for an estimate. he honored the Angie's List deal for a panel upgrade plus a slight upcharge for going from a 100 amp to 200 amp panel. He also inspected an outlet I was having issue with. This original work was done on 5/27/2016. Unfortunately, when the cold weather came and I turned on my electric heat, it didn't work. I called John and he quickly made an appointment for one of his electricians to come out and check the heat on 11/14/2016. Adam and another gentlemen came out and assessed the issue and was able to get the heat back on as the heat was hooked up to another area in the attic of the house, Adam was also able to trace the outlet I had issue with, put a blank cover on the outlet and ensured the wiring was tied off and not an issue. They took there time and found out the issue and corrected it quickly. They also didn't charge me for the second visit. Honest and professional. Do not hesitate to contact John and his guys!"

Customers say: Quick response

"I cannot recommend this electrical service highly enough! I recently needed to have all the circuit breakers in my electrical panel replaced, and the experience from start to finish was absolutely flawless. Electrical work requires a high level of trust, and the electrician completely blew me away with their professionalism, expertise, and attention to safety. They arrived exactly on time, took the time to explain the process clearly, and answered all of my questions without making me feel rushed. The actual replacement of the breakers was done with meticulous care. The wiring inside the panel looks incredibly neat, clean, and organized. Not only did they complete the job efficiently, but they also left the workspace spotless when they were done. It is a massive relief knowing my home's electrical system is completely safe and up to code. If you are looking for an honest, highly skilled, and professional electrician who takes genuine pride in their craft, this is them."

"We needed to put a cable outlet on a wall in our music room where we were relocating a computer, desk, router and speakers, and Mike Stapleford did the job in about an hour or so. He has years of experience and was a nice guy.

"We used Gen3 in the past for a small job and were pleased, so we decided to use them to replace our old knob and tube wiring. Our technicians were nice and friendly. But there were a lot of problems. They did not sufficiently clean up after the work they did each day. We had to clean up ourselves, and our home was full of dust and debris. The workers scratched our floor, dented some kitchen cabinets, took a chunk out of a wall, and did a sloppy job patching up the holes they made during the job. They missed one of our outlets, so we'll have to rewire that one ourselves. They damaged our outside flood lights, and we had to replace them. They did not label the circuits on the new sub-panel they installed. And, I'm sorry to write this, but they used our bathrooms every day for more than just urination. I felt like our home was abused."

FAQs for electrical wiring or panel upgrade projects in King Of Prussia, PA

Yes, a licensed electrician is essential for this project. Running an electrical service from the road to your house involves connecting to utility power lines, complying with national and local electrical codes, and safely handling high-voltage systems. 

Licensed professionals understand proper wire sizing, grounding requirements, and voltage drop calculations needed for safe installation. Most jurisdictions require permits and inspections that only certified professionals can obtain. The safety risks and potential for property damage make this project inappropriate for DIY attempts.

Overhead installations are less expensive than underground options. For a 1000-foot run, overhead service costs between $8,000 and $15,000, while underground service ranges from $10,000 to $25,000. 

Overhead lines require less labor and fewer materials since they don't need trenching or conduit. However, underground lines offer better protection from weather events and aesthetic benefits. Your decision should balance your budget constraints with long-term reliability and visual preferences.

You might need to upgrade your electrical panel depending on your power requirements. If your existing panel cannot handle the additional load from the extended service, upgrading to a 200-amp service (costing $750 to $2,000) may be necessary. 

A licensed electrician can evaluate your current system and determine if an upgrade is required. Factors include what you'll be powering at the end of the line, existing electrical demand, and whether voltage drop over the distance will affect performance.

Running electric service from the road to a house requires electrical permits from your local building department, costing between $500 and $2,000 depending on your location. You may also need excavation permits for trenching work if installing an underground service. Your utility company will have its own application process for connecting to its grid. A licensed electrical contractor can handle all the necessary permit applications as part of their service, ensuring your installation meets all local code requirements.
