"I was incredibly happy with their service. I had Dave upgrade my 100 amp service to a 200 amp service and put a 100 amp sub-panel in my garage. Dave and his Son showed up on time, did a thorough job and did everything for the quoted price. Dave and his Son are very nice people, easy to talk to, and very knowledgeable. I would recommend them to anyone looking for electrical work. I have already hired Dave for another job to add LED lighting and multiple 50 amp outlets in my garage. Can't say enough good things about them. Don't bother looking for other electricians, his prices are more than fair and you will not get better service anywhere else."

FAQs for electrical wiring or panel upgrade projects in Old Lyme, CT

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 Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation.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Yes, rewiring your house is worth it, especially if your wiring is outdated.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