"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."

"☆☆☆☆☆☆☆☆☆☆ 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! ☆☆☆☆☆☆☆☆☆☆"

"I used Grand Bay Electric to replace outdoor receptacles to weather related outlets. Ethan and Christian displayed professionalism, friendliness and respect to my home. I believe the quote to be fair and honest. I also liked Maizey in the office who answered and sent text messages when my appointment moved up a day on their schedule. 5 star company and people!"
