We are not currently offering smaller electrical services, including outlets, fixtures, running wire or panels for things that are not in the home like rvs or boats. We only service electrical panel upgrades within the home and the average cost for this service is around 5000$ but cost will go up or vary according to scope of project. At Diamond Electrical Contractors, LLC our training and experience is second to none. For electrical work you can trust, call the professionals at Diamond Electrical Contractors today!

"I am writing to express my sincere appreciation for the outstanding work performed by Diamond Electric during a recent electrical service upgrade at our property. From start to finish, the entire crew demonstrated professionalism, punctuality, and exceptional craftsmanship. They arrived on time, communicated clearly throughout the process, and completed the work efficiently and safely. What stood out most was their attention to detail—even the smallest aspects of the job were handled with care and precision. It’s not often that you come across contractors who combine technical expertise with such a strong commitment to quality and customer satisfaction. I would not hesitate to work with them again, and I highly recommend their services to anyone in need of electrical work."

FAQs for electrical wiring or panel upgrade projects in Porter, ME

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 Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation.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Yes, rewiring your house is worth it, especially if your wiring is outdated.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.
