Main and Sub Panel Services

Keeping your home, office, or commercial building's electrical system functioning is essential to working safely and efficiently in any environment. Our electrical panel services include maintenance, repair, and installation for current systems and new ones. Having a main panel in place is an important component as it controls permission to the entire building and home. Wherever more circuits are needed, we can install subpanels to assist. We will inspect your current electrical panel box and make sure it is equipped to fit the needs of your space. Don't wait until it's too late — utilizing our electrical service makes sure you have the power to support all your necessary appliances and electronic devices. Let us help you keep your electricals running smoothly for years to come.


Protecting your electrical panel is vitally important. With surge protectors, you can easily add an extra layer of protection to avoid potential damage or destruction from power outages and other electrical issues. In addition to multiple levels of obstruction in the form of circuit breakers, surge protectors provide an added measure of safety against sudden and destructive waves of voltage that can have costly effects on appliances and even fire risk.

When It’s Time to Upgrade or Repair Your Electrical Panel

If you've noticed any of these signs, it may be time to upgrade your electrical breaker panel. 


  • Breakers that constantly trip can be frustrating, as well as lights flickering or dimming.
  • Experiencing power outages should not be seen as a normal occurrence
  • Overuse of extension cords or power strips can also put your family or employees at risk. 
  • Appliances running at full strength is likely not happening if your electrical panel is outdated, and discolored outlet covers point towards a bigger problem. 
  • If you hear burning smells or crackling sounds near appliances, this may be a cause for concern.
  • Even if you are just doing a remodel or adding on to your home, making sure your electrical panel has been updated will benefit you in the long run. 
  • When adding new appliances like hot tubs, A/Cs, or refrigerators to the home, having an up-to-date system that supports these are necessary for a safe operation. 


For more information on panel upgrades, check out our blog posts: What to Expect During a Sub Panel Upgrade, Does My Home Need a Panel Upgrade, All About Arcs, and What to Expect During a Service Panel Upgrade.   


Upgrading the electrical panel can save you from more serious issues down the line - so keep an eye out for these key signs! Also, we recommend upgrading to smart panels. This long-term investment will save money and energy.
