Surge Protection Devices

What is a Surge Protector?

Whole-home surge protection devices are installed by an electrician to protect all your entire electrical system from power surges, ensuring safe power quality to keep your home and property safe. The average home in Chatham-Kent houses roughly $15,000 worth of equipment.

 While some power bars offer surge protection, they only protect the devices directly plugged into it, and require replacement after a major electrical event. Whole home surge protection devices protect against larger power surges and last longer than point-of-use devices. 


A power surge is a brief over voltage in a home’s electrical system. This spike in energy can damage or destroy sensitive electrical devices. It is estimated that 80% of surges are caused by electrical systems inside the home. Surges can damage and reduce the life span of:

  • Water heaters
  • Refrigerators
  • Entertainment systems
  • Electronic Devices
  • Heating and Cooling Systems
  • Computers
  • Washers and Dryers
  • Lighting

“Everyone At Postma is very professional and offers wonderful and prompt service. They have helped us out of two jams one a plumbing emergency and today when our furnace in a rental unit broke and the temperature dropped to 49 degrees they came out right away and got us up and running… I can’t thank them enough and will turn to them again the next time we need something…”

“Had some leaking/flooding from an unknown source, Postma was able to schedule a plumber to come out the same day. Even though the plumber, Mark, was running behind with his other emergency calls after the cold snap he fit us in at the end of his day. Mark was kind, thorough and accurate in diagnosing the issue. Would definitely recommend Mark and Postma to anyone with a plumbing issue.”
