Professional Generator Installations

Our team of professional electricians can safely set up wiring, plug your generator into the transfer switch, and can wire it directly into your service panel. Doing so will ensure that the electricity is delivered safely into your home, preventing your generator from getting overloaded. Failing to install a generator properly can result in back feeding, fires, and other safety issues. Professional generator installations are also essential to prevent carbon monoxide poisoning.

Our team of electricians will inspect your current electrical system and help you find a generator that best fits your needs and your budget. Then we will thoroughly explain the installation process and its cost before any of the work begins.

These guys are fantastic- they're reasonably priced, pleasant and flexible, and the tech who installed our new lighting, Brendan Mahoney- was really enjoyable to have at the house. He was respectful of our home & our pets, and made sure everything was to our satisfaction before wrapping up. Mr Sparky now has a permanent spot in my phone contacts as our go-to electrician. Thank you Brendan & team, we look forward to working with you again!

- Holley Ackerson

I was impressed with how quickly Mister Sparky returned my initial phone call as well as how quickly they were able to schedule my work. Brendan showed up in a timely manner, was friendly, efficient and communicated clearly what he was doing. My overall experience was quite positive and I would definitely use the company again for my electrical needs.

- Brenda Shannon

Brendon did a great job! On time, fast, courteous, and knowledgeable. I recommend Mr Sparky for all your electrical needs.

- Joseph Lavely

The electrician (Brendan) arrived to my house was very professional. He was very knowledgeable and explained everything that he was doing. He gave us an initial price to figure out what was wrong with my wiring and another price for the new ceiling fan to be installed, both prices I felt where reasonable. I will be receiving two quotes for two more jobs that we need done. I am so glad that I contacted them to fix the issue. If anyone needs work done I recommend this company. They are on time and quality of work was wonderful.

- Marie Russell

Brendan did a great job. He was patient when I was irritable about the failed attempts to repair it by other companies who had come out and my worry that we would have the same issue this time. Very reasonably priced and both him and the owner did an excellent job explaining everything they were doing. We're having them come back out next week for another job. Highly recommend
