When you call GLEC, you get a master electrician providing you the highest quality work at a fraction of the cost. You are losing out big time when calling a large electrical company! They will send an unqualified employee, and you will pay the overhead for them to learn on your property. We at Green Light Electrical Contractors strive to maintain our reputation as a high quality, very service oriented company with our main focus being customer satisfaction.
"Ryan was on time and a great worker, couldn't recommend him and his company enough!"

"They did an excellent job of installing the new panel at a reasonable price. Also they had financing options that were same as cash. I was provided some options of circuit breakers and the price with the options. The differences in breaker were explained and the code requirements for my area was also explained and compared to other local code standards. I was able to customize the options a little bit based on my needs and I have more space in the panel if I have additional requirements. Going from a box from the 1960’s to a modern solution mad a lot of sense. The installation was smooth with only a short time without power. Throughout the process, I was well informed of the progress. My family was able to work remotely from home during most of the install without too much disruption. (Used cell phone for internet and laptops while power was off.) They even installed a monitoring system for me to track the electrical use of the house. Overall they did a great job and I am very satisfied."

"Tri State was prompt—they had a tech out within hours when our 20-year-old HVAC broke down. The repair estimate was $800–$1,200, and they also sent a salesman, Mike, to discuss replacement. Mike was courteous and knowledgeable, but, when we sat down to review the quote, the sales process turned into a bad car-buying experience. They started at $34,000, then "discounted" to $29,300—$10,000 -$12,000 higher than other quotes for the exact same unit. Even factoring in their warranty, they remained $8,000–$10,000 overpriced. Mike also claimed they were a four-generation family-owned business, but I later found out they’re owned by Sila Services, a Goldman Sachs private equity firm—which feels misleading. To their credit, canceling was easy (though I hadn’t signed a financing agreement or put money down). Bottom line: Get multiple quotes. Their pricing was excessive, and the sales tactics felt manipulative."

There are several telltale signs that your home is due for an electrical upgrade. You may need to rewire your house if your lights are constantly flickering or your circuit breaker keeps tripping. If you feel mild electric shocks when you touch light switches, hear buzzing sounds, or notice burning smells, you may need to rewire your house, too. Discolored or burnt-looking switches and faceplates are another crucial warning sign.
Properly installed copper wiring in a residential property can last as long as 50 to 100 years in some cases, but many homes over 30 years old are due for an upgrade. That’s the timeline that many experts recommend, even if it is only a partial update to accommodate technological advancements, increased power demands, and changing safety requirements.
At $3 to $5 per square foot, the cost to wire a 2,000-square-foot house ranges from $6,000 to $10,000, on average. This can depend on many factors, like the age and complexity of the house and how easy it is for contractors to access the areas they need to get the job done. Opening and repairing walls can further add to your total cost.
