Electrical Wiring or Panel Upgrade
They did a project at my sons home to replace an old 100 amp fuse panel with new upgraded 200 amp breakers and new service entrance. Did an excellent job. Work was done professionally and timely. I would hire this company for future electrical repairs.

Electrical Wiring or Panel Upgrade
The electrician was very knowledgeable and friendly. He did an electrical panel upgrade in our house that required a second panel. He also upgraded electrical outlets and plugs for us that were older and needed to be replaced. We had a new plug installed for our electric dryer. We have already been in touch with them to install a new generator we just got and update the rest of the outlets in our home. He kept the work area clean and cleaned up after he was finished. Great work! We are very satisfied.

The team did an amazing job and we have no issues. What I really appreciated was how friendly they were. We weren't just another customer who they were trying to just finish a job for, they took the time to speak with us. It was really appreciated.

I called 7 electricians before Desmond with no one answering the phone. His reply was “I will be there in an hour.” We lost power while temperatures were well below zero, he arrived and quickly found our main breaker failed and did the replacement. Great service, price and customer service couldn’t be better! I will be referring him to my friends and family. Thanks again Desmond

Electrical Wiring or Panel Upgrade
I had to make an appointment two weeks earlier because I was out of town. I lost Mr. Haney s number and could not confirm. To my surprise Mr Haney showed up on time was professional and extremely way to do business with. He even has his billing system setup so it is easy to pay. I will use mainstream again and again.

Electrical Wiring or Panel Upgrade
Desmond is always prompt on returning text messages and emails. I liked his strategic planning of where each recessed light would be placed, assuring to have light exactly where it would be needed and placed for looks aswell. It came out really lovely. He also rewired our electrical box when all the wiring was found in the soffit we had removed. The wiring was to short to get into the wall and he made it happen so we could drywall. I definitely recommend Desmond for any electrical project you might have or want done.
