"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

Yes, tamper-resistant outlets are designed to be safe for use in homes with children. They feature a spring-loaded shutter that blocks the electrical slots when not in use, which helps protect children from electric shock if they try to insert an object. While they are the safest option available and highly effective, it's important to note that few things are truly 'childproof.' Children may still try to imitate adults by inserting a plug. For this reason, it's best to use tamper-resistant outlets over less effective solutions like plastic covers, which can be removed or pose a choking hazard. Always supervise young children around any electrical outlets or devices.

Many wire nuts can accommodate three wires of various gauges; you should check the packaging of the nut to confirm you are buying the correct size. In addition, there are screw terminals that accommodate various numbers of wires; these might also be called “terminal blocks,” and exist to connect multiple wires. 

A standard three-prong electrical outlet typically lasts for about 15 years with normal use and should be replaced accordingly. GFCI outlets may have a longer lifespan of 15 to 25 years. While some outlets can last longer if used infrequently, they can also fail prematurely. Reasons for early failure include poor wiring, an overloaded circuit, improper grounding or installation, or loose plugs. Signs that an outlet is failing include flickering lights, overheating, a discolored or melted faceplate, plugs that fall out easily, or frequently tripping circuit breakers. It is essential to address faulty outlets promptly to avoid safety hazards, especially in homes older than 15 years.

At a minimum, you need an electrician to inspect the house wiring after a fire. The electrician will need to replace damaged or melted wires. If the electrical wiring is old, about 25 years or more, you should rewire the house after a fire. Old wiring can increase the risk of another fire, so replacing the wires is the safest option.

If wiring in a relatively modern home is damaged due to sudden events like a fire, a tree falling into the house, or a flood, then homeowners insurance is very likely to cover the cost of replacing the wire.

However, if it’s determined that wiring failed or started the fire because of age, neglect, or not meeting current electrical standards, then insurance won’t be covering any replacement. Also, insurance policies may charge more for particularly old kinds of wiring like aluminum wiring or deny applications altogether.
