Electrical reviews in Naperville, Illinois

I had a great experience with Cob Services LLC. From the first call to the completion of the job, everything was handled professionally and efficiently. The team was punctual, knowledgeable, and took the time to explain exactly what needed to be done.

What really stood out was their attention to detail and commitment to doing the job right the first time. You can tell they genuinely care about quality and safety, which is hard to find these days. They also kept everything clean and organized, which I really appreciated.

If you’re looking for reliable electricians who are honest, skilled, and easy to work with, I highly recommend Cob Services. I’ll definitely be using them again for future projects.

I’ve been working with Alex from Cob Service LLC for the past three years, and I couldn’t be more satisfied with his work. He has helped me with multiple projects around my home, including installing can lights and adding electrical outlets.

Alex is extremely professional, reliable, and detail-oriented. Every job he has completed has been done with great care and high-quality workmanship. On top of that, his pricing is very fair, which makes him even more valuable.

I’ve referred Alex to several of my friends, and every one of them has had a great experience and speaks highly of his work as well. It’s rare to find someone so consistent and trustworthy.

Highly recommend Alex for any electrical work!

Alex amd his team have done an amazing job. Ever since they helped the first time putting lights in my basement, in my kitchen and my kids bedrooms. Now any electrical issue I encounter I know who to call. Highly recommended 👌 👍 👏

I recently hired this company for a full electrical rewire of my home, as well as the installation of a Tesla charger, and the experience was excellent from start to finish.
Their pricing was fair and transparent, with no surprises along the way. The team was professional, knowledgeable, and clearly experienced in both residential electrical work and EV charger installations.
What stood out most was their reliability — the project was completed on schedule, and the quality of work met high standards. They communicated clearly throughout the process and made sure everything was done safely and correctly.
I would highly recommend them to anyone looking for dependable electrical services, whether for a full home rewire or EV charger installation.

Certainly 5 out of 5.. Very professional, knowledgeable and diligent..

Alex has helped me multiple times with electrical work at my rental properties, and he’s always been very reliable. He shows up on time, quickly figures out the issue, and gets it fixed without any hassle. It makes managing rentals much easier knowing I can count on him. Easy to work with and very efficient—I’ll definitely keep calling him.

Alex is the ultimate professional! He was my favorite sub-contractor that my contractor used on our addition. Very responsive to all of my questions and add-on jobs. If he can't do it, no one can! He is just the best! I also liked his helper a lot! A++
