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.

For the statistics on why insurance companies get hot about water heater replacement, read our blog “Why is an older water heater an insurance problem?”

If you are not sure how old your water heater is, find out at our blog “How do I decode the water heater serial number to figure out the age?”

Also, to learn about common installation defects, see our blog “What are the most common problems with water heater replacement?”

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.
