"It went well. Some of the wall to fixture wiring had been previously updated, but most of the wiring running from attic to basement needed to be replaced and grounded fixtures all throughout. It was a big task. Brad mapped it all out days before starting the job. One thing Brad prides himself on is customer service, and he carried that out through the entire project. There was change orders, as well as punch list items, and he took care of all of them promptly and efficiently. Brad was on the job site most of the time, and when he wasn't he was in constant communication with his two crew members (both very nice fellows)."

"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!"

"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, the owner quoted me the best price and did not try to upsell me on additional work like another contractor from Angie’s list. They showed up on time on the scheduled date and completed the work in a timely manner with no surprises or additional costs. I would use them again."

"We were selling our house and came to find out that basement electrical panel had never received its final inspection when it was finished.  As a result, we had to bring everything up to current codes, which included child-proof outlets.  There were at least 25 outlets.  They changed all of them out, and arranged to have a final electrical box inspection.  There were a couple of other minor issues they noticed and took care of while doing the work.  Also, 2 outlets had to be changed into GFCI outlets.  Mike and his crew were very friendly and professional.  They initially did an estimate, and then came back pretty soon after we requested the work.  I was very happy with them and felt I could trust them, and I felt the price was extremely reasonable for what they were doing.  I will definitely use them again.

"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

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
