HOME INSPECTION

Welcome to our blog!
We want you to be an informed homebuyer, and each blog post is a question that we have answered for our friends and customers over the years. Hope they help you make a good choice for your next home.

   The question we are often asked when explaining the insurance issue facing homes with older fuse-panels is this: “But the current owner has insurance. Why can’t we just go with their company after we buy the house?” The difference is that insurance companies are slow check up on current policy-holders and require them to upgrade but, when issuing a policy to a new owner, they want the home to meet their latest minimum standards.

   When a home is first built, the designer calculates the required size electric service based on the square footage and electric appliances planned. Electricity usage has been growing at a rate of approximately 5% per year for a while now and, as TVs keep getting bigger and kitchens fill up with more and more counter-top appliances, the trend is likely to continue, even in this era of fluorescent light bulbs and Energy-Star ratings.

   So a healthy size electric service is a good idea. But 200-amp service is not necessarily the gold-standard for homes, even today. For a small home or condo, 125 amps is adequate; and 150 amps is quite satisfactory for many average size family homes, especially if they have any gas-powered major appliances.

   If we feel that the size of the electric service is questionable during a home inspection, we will recommend that a licensed electrician calculate the estimated loads in the home and advise if a service upgrade is recommended. More often than not, though, they will say that the service in an older home--dating back to about the mid-1960s--is still adequate.


While we hope you find this series of articles about home inspection helpful, they should not be considered an alternative to an actual home inspection by a local inspector. Also, construction standards vary in different parts of the country and it is possible that important issues related to your area may not be covered here.
