"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."

"I hired Prime Sine Electric LLC for a complete new electrical service and wiring on our 1937 home when purchased. It was in need of a complete gut-job. Spence did an amazing job bringing it up to today's standards. I mean, totally amazing transformation. Spence was professional the entire time through the quote process, customer service and final completion. He listened to our needs and gave input and helped us with planning the electrical needs of this old house. We can't recommend Spence enough and would hire him again in an instant."

"The problem turned out to be a burned out small electric door switch. I believe the price was way too expensive for the service performed and the price of the door switch. What more can I say? It got done."

Electrical questions, answered by experts

Aluminum wiring can pose a fire risk as it can overheat, expand, and contract, leading to failing splices and loose connections. If your home has aluminum wiring, it requires careful maintenance and potential safety upgrades. The first step is to hire a licensed electrician to conduct a thorough inspection.

A complete replacement with copper wire is the safest option but can be very expensive and is not always necessary. Other safety measures and upgrades include:

  • Copper Pigtailing: A more budget-friendly option where a short section of copper wire is added to each end of the aluminum wire. This is only appropriate for certain homes.

  • Aluminum-Compatible Outlets: Installing outlets specifically designed for use with aluminum wiring.

  • Anti-Oxidant Paste: Applying this paste to connections to prevent oxidation.

Consulting with a qualified electrician is essential to assess the condition of your wiring and determine the most appropriate updates to meet current safety standards.

Inverter generators are designed to turn on the engine when your appliances demand more energy. This is in contrast to running at full capacity as soon as they’re turned on, like a standard portable generator does. So long as the wattage rating is high enough, an inverter can power a refrigerator just as well as a traditional generator.

While you can technically live in a home while it's being rewired, prepare for some debris and dust if your electrical contractor needs to remove parts of walls, floors, and ceilings to access wires. If you stay home during the project, ask your electrician to cut the power supply to all exposed electrical wires to keep your family safe.

If you plan to have a refrigerator or other appliances that require electricity, you will need an electrical outlet in your outdoor kitchen. Be sure to comply with all National Electrical Code® (NEC®) codes for electrical wiring and outlets in kitchens. If you do not plan to install a refrigerator or any other appliances that require electricity as part of your outdoor kitchen features, then you do not need to install electrical outlets. However, it is a good idea to install at least one electrical outlet should you decide to use any appliances that require electricity.

A faulty light switch can trip a breaker due to circuit overload or a short circuit. A faulty light switch may not always trip a breaker, so don’t use that as your only sign that something’s wrong. Always investigate the cause of a switch that isn’t working properly, feels hot to the touch, or is making unusual noises.
