Junior replaced four long light fixtures and multiple outlets/switches. He was professional and very patient to get the job done correctly. I highly recommend him.

Junior was precise, fast and professional. He dealt with unexpected calmly and methodically. I plan to hire him for my future electrical projects.

Hey Junior. Great work today. Thanks again for your knowledge and expertise in getting the wiring to my hot tub corrected and safely up to code. We can finally enjoy our white cedar tub again!!!

I stayed home today for this installation. The installer is now 3 hours late. Lowe's said that I will have to reschedule my installation. I will again have to stay home. I am VERY unhappy. I called Thumbtack 3 times today. The first time I was on hold for 75 minutes, then disconnected. I called again. I was on hold for 45 minutes. I spoke with someone for a moment, but he hung up on me. I called for a 3rd time. There was another long wait on hold, so I hung up and called Lowe's. I have spoken to the customer service representative for installations. She escalated the issue further. How can you send a request to rate an installation that hasn't occurred? No one called. No one texted. No one emailed. This is totally unacceptable.

They helped me troubleshoot a tricky breaker issue, and returned to my house several times free of charge until the issue was fully resolved.

They were very professional and did the work in a timely manner. Very respectful as well.

Junior at Marconis Construction & Electric was a lifesaver. This happened on the Friday before Easter weekend, and I was having a hard time getting anyone to even call me back. Junior responded quickly, came out, and diagnosed the problem right away. He found that some of the wire connections in the panel had not been torqued properly, and he also discovered a Siemens breaker that had to be replaced because moisture had gotten inside and caused corrosion. He explained everything clearly, fixed the issue the right way, and charged a fair price. The breaker replacement was only a small additional cost, which was completely reasonable. What I appreciated most was that he knew what he was looking at and didn’t waste time guessing or trying to sell me things I didn’t need. Responsive, honest, knowledgeable, and professional. I would definitely call Junior and Marconis again.

Junior was very responsive and did great job. We were happy with hs quality and efficiency. Responded within hours of posting the request and completed the same day.

I would definitely recommend Marconis to anyone looking for professional work at a reasonable cost. Junior was responsive and clear, setting expectations and following through. His work is clean and I'm so happy with the result. He put in some recessed lighting with a new switch, as well as a junction box in case we wanted to do any future electrical work. While at the same time he managed to do the work without putting unnecessary holes in our wall, which I always appreciate. Not to mention he offered to fix a faulty switch while he was simply here for a consultation. He was very respectful of our space and polite, it was a real pleasure having him here. Our dog like him too, always a good sign. I'm not the most experienced hiring people to do work on the house and always wary of the task given some of the horror stories. But he made it easy. Never did I feel like I was being taken advantage of or upsold. 100% would call him again if we ever need an electrician.
