Here at GJC Electric, LLC, customer service and quality electrical work is what we were founded on. We were built on quality and affordable electrical work which in turn provided long lasting relationships with our customers. We strive to provide a superior service experience to all of our customers and live by our 100% customer satisfaction guarantee.

"Iâ ve used GJC Electric twice. On both occasions the service was outstanding. Iâ ll start my review with the second occasion because Gregâ s help exceeded all expectations. It was an emergency repair for a bad wire in the meter box. For all of you who donâ t know, owners are responsible for this part of the system ( I thought it was PECO.). PECO inspected the box and deemed it unsafe and turned off the electric. At 4pm. I called GJC and Greg was on the site and completed the job within 3 hours. His prompt response averted a complete catastrophe! I previously used his services for the electrical wiring of a kitchen and bath remodeling job. This was completed in a timely manner and he was helpful with design and worked great with the other contractors on the job! Professional, fair pricing, prompt, neatness, collaborative and helpful all come to mind. So glad I used this electrician. Highly recommend!!!"

FAQs for electrical wiring or panel upgrade projects in Warminster, PA

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
