  • I highly recommend J.D. Patrick Electric. We had to have some major electrical work done. I had conversations with other electrical firms before I settled on J.D. Patrick Electric. This company definitely stood out in the crowd. They were able to answer all of my many questions and I trusted them implicitly with the decisions they made regarding a solution to our electrical problem. The day the work was being done, the electricians here were courteous, thoughtful and incredibly hard working. I was very impressed at the calibre of work and the way they were able to solve some hurdles which arose during the work day. They remained after the work was completed and did a complete clean up both inside and out. I will continue to use this company and I strongly urge anyone who needs electrical upgrades or repairs to use J.D. Patrick Electric Inc. You will not find a better company for electrical work.
