Cost to Install Lightning Protection

Many people assume that their homes are protected from lightning, but the reality is that a bolt during a thunder storm can do significant damage to your property. Along with the immediate threat of fire, lightning can fry your electrical systems as well as any electronic items plugged in at the time of the strike. Thankfully, there is one defense against this threat. Hiring professionals to install lightning protection can be a smart move that protects your home as well as your family.

Average Cost of Lightning Protection Installation

Before you begin looking at prices or providers for a lightning protection system for your home, it can be a good idea to get an average price range for the installation. Of course, prices vary from location to location and home to home, but you can expect to be within the range of $897 and $1,395 if you want average protection.

Factors Influencing the Cost of Protection

The biggest factor that influences the total cost of professional lightning protection installation is the size of the home. The more square footage you own, the longer it will take to secure the space from electrical and fire damage in the event of a lightning strike. Height, too, is a significant issue, because taller homes are more susceptible to lightning damage. Systems can vary from a relatively basic single lightning rod used in conjunction with a grounding cable to a more effective system featuring multiple lightning rods. Ultimately, the price of any professionally installed lightning protection system will depend on your overall needs as well as your budget.

Cost of Surge Arresters

An additional cost that you may encounter when professionally installing lightning protection in your home is that of a surge arrester. This device works as a kind of surge protector for your entire electrical system, and it can protect any electrical devices in your home. If you have several computers, tablets, laptops or expensive televisions that remain plugged in most of the time, this $50 to $200 investment may be more than worth the initial expense.

Lightning protection may add to your budget, but protecting your home is certainly worth the cost.
