"Wonderful service! We had a whole house generator installed. Charles and Joyce were a joy to work with from quote to finish. They completed the work on the days promised. Scheduling to completion was quick and easy. They did everything right and was clean and neat and we are very pleased. We would recommend this company to anyone and would call them first if needed for any future projects. Wonderful company! Great people!"

"Tom Mullaney and his team at Wire Works Inc. are top notch. Very professional, responsive, and reasonably priced. Wire Works most recently assisted as with all our electrical needs for a complete kitchen remodel - new outlets, switches, can lights, pendant lights, stove hookup, etc. When the team wasn't able to complete all tasks on the scheduled day for our rough electrical, they found a way to squeeze us back into the schedule so our kitchen remodel could stay on schedule. Tom Mullaney is one of the nicest people you'll meet, and provides an outstanding service. I won't use anyone else."

"Andrew came to our house between Ann Arbor and Plymouth at 8 PM on Tuesday when a storm caused an electrical outage. We had a generator but we're only getting partial power in the house. Andrew ran tests inside the house, determining that not enough power was coming into the house. He then started testing different areas of the generator until he found the part not working. Once he located the problem, he quickly fixed it. Because he didn't give up on me or my problem, he restored electricity, saving me hundreds from food spoilage in a refrigerator and freezer. I don't think most electricians would have stuck with the problem or been able or willing to fix the generator. If I could give more than 5 stars, I would."

"☆☆☆☆☆☆☆☆☆☆ Amazing! I had a panel upgrade on a house over 100 yrs old, and 4 dedicated circuits installed, as well as having it future proofed for things I may have - solar, an electric vehicle, central air, a generac, and an ADU (Accessory Dwelling Unit (ADU/aka Tiny House) They were prompt, courteous, and very reasonably priced, as well informative ‐ gave me a pretty accurate quote upfront And always let me know when they would be over, what they were going to do, and how long it should take them. Only took them a handful of visits. When I need electrical services in the future I will definitely be calling them back! ☆☆☆☆☆☆☆☆☆☆"
