The answer to 'how much to replace surge protection in my area' is that the cost can vary significantly depending on several factors. Generally, the cost to replace surge protection for a home can range from a few hundred dollars up to $1,000 or more, depending on the size of your home, the type of surge protection needed, and whether any electrical work is required.
The biggest factors that influence the cost include the size and complexity of your electrical system, the quality and features of the surge protector, and whether you need to hire an electrician to handle the installation. Homes with more electrical circuits or larger service panels may require more extensive surge protection, which can increase the overall cost. Additionally, whole-home surge protectors that connect directly to your main electrical panel tend to be more expensive than plug-in or power strip style surge protectors.
