Mark was very efficient in fixing a few electrical issues we had at home. We had another electrician (different company) come in before him who felt the job was too big & complicated, but Mark figured it out. Reasonable price too. I would use the company again.
4wire has become our go to electricians. They installed pots, fans, outlets, a panel and an electrical fireplace. They’re reliable, prompt and efficient. We’ve been very pleased with their service. Keep up the great work, gents! Highly recommend!
I had my 40-year-old electrical panel changed and some basement wiring fixed by 4wire. I would highly recommend this company as they were professional and courteous from beginning to end. Their prices are also extremely reasonable.
Really great experience with these guys - professional crew, fast & high quality work, and they took the time to explain things to me when I had questions. Price was more than reasonable as well. I won't hesitate to call them again for any other electrical work.
Flexible scheduling, no job too small attitude and great work on top of that.
These folks showed up very quickly and were extremely good-natured about the fact that it was a simple fix. Fast and friendly! Happy to recommend them.
