About This & That


~ About our services

    We offer complimentary lighting consultations, budgeting plans, shopping assistance as well as financing referrals and try to answer questions over the phone when we possibly can.  Our estimates are free. 

We are now scheduling appointments for free CSST gas piping inspections to let you know if your home has this dangerous piping that can cause house fires and even explosions which was reported by the Today Show, CNN and has also happened locally.  Please contact us for more information and to schedule your free CSST inspection (within our service area).

     In a time when excellent customer service is a rarity, I would be remissed if I did not share my wonderful experience with Cornerstone Electric. Bobby, the electrician, was always on time asscheduled, professional and most importantly respective of my home. He completed several electrical jobs expediently and exceptionally. I highly recommend Cornerstone Electric for all your electrical needs. I will certainly use them for all my electrical needs. Thank you, Cornerstone Electric.

    Once again I had a very positive experience with Cornerstone Electric. Mr. (Allison) is very professional, knowledgeable and a great person to talk to. He installed a video doorbell for me today and I could not have asked for better service. He was om time, in fact, he was a bit early,and I sure appreciated that. He took care of the service call, did not waste time and I WILL CALL HIM AGAIN if I need more electrical work done. Thanks Mr. (Allison) for a job well done.

​​~About Us

  Cornerstone Electric is owned by Bobby and Sheryl Allison.  Bobby not only has over 25 years of experience and also holds a technical degree in Commercial/ Industrial/ Residential Electricity, which is a huge advantage; very few electricians have any type of formal education or degree.  We specialize in residential clients only and work with homeowners, property managers, realtors, home inspectors and house flippers among others.  Our hours are well beyond the typical 9 to 5 so that we can take exceptional care of our clients.  We offer several programs like our financing referral program, Budget Savers (where we help you break down large projects into more manageable steps to fit your budget) and Refresh (our lighting staging service for homes for sale that can make all the difference when the home is empty) to help our clients.  The National Electric Code (NEC) as well as local county regulations are strictly followed.

   Sheryl will probably be the first one you speak with or get an email or text from.  We put our clients first whether we are working on a multi million dollar home or putting in a ceiling fan- both are equally important to us.  Our BBB report can be viewed at  and our company motto is 2 Corinthians 8:21-  For we are taking pains to do what is right not only in the sight of the Lord but also in the eyes of man.
