"These guys came out and worked in the dead of cold in the winter in an old barn and got the job done. It was a good value for the price point. They aren't the cheapest but you wouldn't want that with a professional electrician. John has a good crew of people working with him and they'll get the job done. This was a 100 amp to 200 amp upgrade with a sub panel and electric car charger install."

"Roy and his crew installed a media wall for us. It was much more a construction project than electric, but they did both beautifully and managed it very professionally, cleaning up after themselves and doing an extremely precise job. Cost was reasonable compared to other quotes. They are busy, so be prepared to wait a little on scheduling and communication. We plan to hire again!"

FAQs for electrical wiring or panel upgrade projects in Portland, 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 Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation.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Yes, rewiring your house is worth it, especially if your wiring is outdated.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.
