When you need more than just an electrician.


Mark Collum, Owner

"Give me a call or email me with any questions you may have on your electrical project."

Being without power can be a huge inconvenience… or worse… a huge fire hazard if it’s because of faulty electrical equipment!  When the power goes out because of an equipment failure, it usually means that a component has overheated and failed!

If you have a main electrical service that needs some TLC or if you have been thinking about  upgrading  your electrical service – now is the time!   We have a solution to fit your needs whether it’s a minor repair or a complete replacement/upgrade.

Hello, my name is Mark Collum and I am the owner of Collum Electric Service, LLC.  My dad, Bob Collum started the business back in 1971 when  he saw a need for electrical services in the local area.  He focused on providing quality service and building relationships with customers in the community.  I grew up looking over my dad’s shoulder learning the trade and gaining valuable experience.  I then went on to school to study industrial maintenance technology and worked for an electrical contractor in Cedar Rapids.  After receiving my Journeyman and Masters license I returned to work for my Dad and eventually took over the family business in 2014 when he retired.  We strive to continue on with his core values of quality service and valued relationships.

Once we upgrade your electrical service, you won’t have to worry about your main power system for many years.  You will have peace of mind knowing your electrical service and breaker panel is properly installed by our qualified electricians. 

Once you contact us to set up your FREE consultation, we will come out and survey your existing electrical system and discuss what your future power requirements may be.  After we gather all of the necessary information we will then provide you with a no obligation proposal to have the work completed.  Here are a few of the benefits you will receive if you choose to do business with my company:

  • Free Consultation
  • Quick lead times to have the work completed
  • Convenient Scheduling
  • Our services are backed by our customer satisfaction guarantee.  We make sure you are 100% satisfied with our work before we step foot out the door… or we make it right! 
  • Minimum 3 Year Warranty on Labor and Materials.  If your breaker panel or main service gives you any trouble during that period, we will repair the problem FREE of charge.
