"We had an absolutely amazing experience with this father-and-son team! They own and operate their electrical company full time and also do furniture assembly, and we could not have been happier with the job they did for us. They arrived at 9:30 in the morning and stayed until around 6:30 that evening, making sure every single piece of furniture was completely assembled before they left. Everything came out beautifully, and they were incredibly hardworking, efficient, careful, and thorough. On top of that, they were both so friendly, personable, and pleasant to have around all day. Their pricing was also fantastic — by far the best of all the quotes we received. We were so impressed with their work and felt they deserved even more than what they had quoted us, so we were happy to tip them extra. We would 100% recommend them to anyone looking for reliable, skilled, hardworking people who genuinely care about doing a great job. We will be keeping their number for any future projects!"

"We were very happy with the work.Eric was easy to work with. He installed a new 220 circuit and was able to fish it though the walls harmlessly whereas other electricians we talk with were going to tear up the drywall. Pricing was very reasonable. Highly recommend."

"I have a very good impression of Mr. Morton and appreciate his efficiency and speed in getting my generator back in service. I have asked him to put me on his list for a yearly evaluation. I am trusting that the next time there is a power failure my generator will be back in operation."
